Description

网页截图方法、装置及设备Webpage screenshot method, device and equipment

技术领域Technical field

本说明书一个或多个实施例涉及计算机技术领域，尤其涉及一种网页截图方法、装置以及设备。One or more embodiments of this specification relate to the field of computer technology, and in particular to a method, device, and device for screenshotting a webpage.

背景技术Background technique

目前以文本、图片为主的版权保护领域，网站侵权是最常见的现象。而在针对网站侵权进行诉讼时，最大的诉求就是侵权证据的获取。这里的侵权证据可以是指对侵权网站的网页截图。At present, in the field of copyright protection where texts and pictures are the mainstay, website infringement is the most common phenomenon. In litigation against website infringement, the biggest appeal is to obtain evidence of infringement. The evidence of infringement here can refer to a screenshot of the webpage of the infringing website.

传统技术中，网站的网页截图的获取过程可以为：先基于浏览器加载网页，然后直接将加载后的网页转存为图片。然而由于网页的加载通常会受多方面因素的影响，因此，在基于传统的方法获取网页截图时，会存在网页截图不一致的问题。比如，当在不同的地理位置，访问同一网页时，浏览器加载的网页可能会不一致，从而导致获取的网页截图也不一致。再比如，网页的加载还会受到历史环境的影响等等。In traditional technology, the process of obtaining a screenshot of a webpage of a website may be as follows: first load the webpage based on the browser, and then directly transfer the loaded webpage as a picture. However, since the loading of a webpage is usually affected by many factors, when a screenshot of a webpage is obtained based on a traditional method, there will be a problem of inconsistent webpage screenshots. For example, when visiting the same webpage in different geographic locations, the webpages loaded by the browser may be inconsistent, resulting in inconsistent webpage screenshots. For another example, the loading of web pages will also be affected by the historical environment and so on.

因此，需要提供一种更可靠的网页截图方法。Therefore, it is necessary to provide a more reliable method for taking screenshots of web pages.

具体实施方式Detailed ways

下面结合附图，对本说明书提供的方案进行描述。The following describes the solutions provided in this specification with reference to the accompanying drawings.

在描述本说明书提供的方案之前，先对本方案的发明构思作以下说明。Before describing the solution provided in this specification, the following description of the inventive concept of this solution is made.

为了避免网页的加载受历史环境的影响，申请人考虑先在沙箱环境中启动实例，这里的实例可以包括但不限于Docker容器或者虚拟机等，之后在启动的实例中，运行指定浏览器来加载待截图网页。In order to prevent the loading of web pages from being affected by the historical environment, the applicant considers to start the instance in the sandbox environment first. Examples here can include but are not limited to Docker containers or virtual machines, etc., and then run the specified browser in the launched instance. Load the web page to be screenshot.

上述Docker容器是由开发者通过集装箱(Docker)(一个开源的应用容器引擎)将应用程序以及程序的依赖包打包到一个可移植的Docker镜像文件中，之后运行这个Docker镜像文件所启动的。在该Docker容器中，应用程序可以像在真实的物理机上一样正常运行。基于Docker镜像所启动的多个Docker容器之间不会有任何接口，也即Docker容器之间是相互隔离的。另外，对于虚拟机，其也具有隔离型。The above-mentioned Docker container is started by developers who package the application and program dependencies into a portable Docker image file through the container (Docker) (an open source application container engine), and then run the Docker image file. In this Docker container, the application can run normally as if it were on a real physical machine. There will be no interface between multiple Docker containers started based on the Docker image, that is, the Docker containers are isolated from each other. In addition, for virtual machines, it also has an isolation type.

需要说明的是，Docker容器(或者虚拟机)的隔离性，可以确保网页的加载不受历史环境的影响。此外，通过指定浏览器来加载待截图网页，可以避免由于浏览器的不同，而导致的所加载网页的不同。It should be noted that the isolation of Docker containers (or virtual machines) can ensure that the loading of web pages is not affected by the historical environment. In addition, by specifying the browser to load the web page to be screenshotted, the difference in the loaded web page due to the difference of the browser can be avoided.

此外，基于上述截图方法所获得的目标截图可能会存在被篡改的风险。因此，避免目标截图被篡改也成为要解决的问题。In addition, the target screenshot obtained based on the above screenshot method may be at risk of being tampered with. Therefore, preventing the target screenshot from being tampered with has also become a problem to be solved.

区块链技术是一种互联网数据库技术，其特点是去中心化、公开透明、不可篡改以及可信任。因此，本方案可以引入区块链技术。具体地，网页截图服务器在获取到目标截图之后，可以向区块链网络的多个节点中任意的第一节点发送目标截图，以使第一节点在对目标截图的真实性验证通过后，对目标截图进行存储。还使第一节点向区块链网络中的其它节点广播目标截图。由此，实现了目标截图在区块链网络中的存储，从而可以避免目标截图被篡改的风险。Blockchain technology is an Internet database technology, which is characterized by decentralization, openness and transparency, immutability and trustworthiness. Therefore, this solution can introduce blockchain technology. Specifically, after obtaining the target screenshot, the webpage screenshot server may send the target screenshot to any first node among the multiple nodes of the blockchain network, so that the first node can verify the authenticity of the target screenshot. The target screenshot is stored. It also makes the first node broadcast the target screenshot to other nodes in the blockchain network. As a result, the storage of the target screenshot in the blockchain network is realized, thereby avoiding the risk of tampering with the target screenshot.

以上就是本说明书提供的发明构思，基于该发明构思就可以得到本技术方案。以下对本方案进行详细阐述。The above is the inventive concept provided in this specification, and the technical solution can be obtained based on the inventive concept. The following describes this scheme in detail.

图1为本说明书提供的网页截图***示意图。图1中，该***可以包括网页截图服务器以及区块链网络。其中，网页截图服务器可以接收用户的网页截图请求。在接收到该请求之后，网页截图服务器可以先启动Docker容器或者虚拟机，之后在启动的Docker容器或者虚拟机中，运行指定浏览器来加载待截图网页，并对该截图网页进行截图，以得到目标截图。在获取到该目标截图之后，网页截图服务器可以将目标截图存储到区块链网络中。Figure 1 is a schematic diagram of the webpage screenshot system provided in this manual. In Figure 1, the system can include a webpage screenshot server and a blockchain network. Among them, the webpage screenshot server can receive the user's webpage screenshot request. After receiving the request, the webpage screenshot server can start the Docker container or virtual machine first, and then run the specified browser in the started Docker container or virtual machine to load the webpage to be screenshotted, and take a screenshot of the screenshot webpage to get Target screenshot. After obtaining the target screenshot, the web page screenshot server can store the target screenshot in the blockchain network.

图1中的区块链网络可以包括多个节点，其中，任一节点均可以接收上述目标截图。在接收到目标截图之后，该节点可以对其真实性进行验证，并在验证通过时，对其进行存储。此外，该节点还可以向区块链网络中的其它节点广播该目标截图，以使得其它节点在对该目标节点的真实性验证通过后，对其进行存储，由此，就实现了目标截图在区块链网络中的存储。The blockchain network in Fig. 1 may include multiple nodes, and any node can receive the above-mentioned target screenshot. After receiving the target screenshot, the node can verify its authenticity and store it when the verification passes. In addition, the node can also broadcast the target screenshot to other nodes in the blockchain network, so that other nodes can store the target node after the authenticity verification of the target node is passed, thereby achieving the target screenshot in Storage in the blockchain network.

应理解，在实际应用中，图1中的网页截图服务器的个数也可以为多个。当为多个时，用户可以随机选择其中一个来发送网页截图请求。可以理解的是，多个网页截图服务器可以大大提升网页截图***的负载。It should be understood that, in actual applications, the number of webpage screenshot servers in FIG. 1 may also be multiple. When there are more than one, the user can randomly select one of them to send a web page screenshot request. It is understandable that multiple web page screenshot servers can greatly increase the load of the web page screenshot system.

图2为本说明书一个实施例提供的网页截图方法流程图。所述方法的执行主体可以为具有处理能力的设备：服务器或者***或者装置，如，可以为图1中的网页截图服务器。如图2所示，该方法具体可以包括步骤202至210。Fig. 2 is a flowchart of a webpage screenshot method provided by an embodiment of this specification. The execution subject of the method may be a device with processing capability: a server or a system or a device, for example, it may be the webpage screenshot server in FIG. 1. As shown in FIG. 2, the method may specifically include steps 202 to 210.

步骤202，接收用户的网页截图请求。Step 202: Receive a web page screenshot request from the user.

该网页截图请求至少可以包括待截图网页的URL地址。此外，还可以包括用户自定义的截图规则。该截图规则至少可以包括针对待截图网页所需执行的目标操作。这里的目标操作可以包括但不限于点击操作、关闭操作以及滑动操作等等。此外，还可以包括截取区域或者截取像素范围等等。The webpage screenshot request may at least include the URL address of the webpage to be screenshotted. In addition, it can also include user-defined screenshot rules. The screenshot rule may at least include a target operation that needs to be performed on the webpage to be screenshot. The target operation here may include, but is not limited to, a click operation, a close operation, a sliding operation, and so on. In addition, it may also include a clipping area or a clipping pixel range, and so on.

举例来说，当用户需要针对网页底部内容区域进行截图时，该截图规则中可以定义相应的点击操作。该点击操作具体可用于点击网页中的用于表示加载全文的按钮，以便可以加载网页的底部内容。此外，该截图规则中还可以定义截取区域：底部区域等等。For example, when a user needs to take a screenshot of the content area at the bottom of a webpage, the corresponding click operation can be defined in the screenshot rule. The click operation can be specifically used to click a button in the webpage for loading the full text so that the bottom content of the webpage can be loaded. In addition, the screenshot rule can also define the interception area: the bottom area and so on.

步骤204，运行沙箱环境的镜像文件，以在沙箱环境中启动第一实例，并在第一实例中运行第一浏览器。Step 204: Run the image file of the sandbox environment to start the first instance in the sandbox environment, and run the first browser in the first instance.

在本说明书中，第一实例可以包括但不限于Docker容器或者虚拟机等。In this specification, the first example may include, but is not limited to, a Docker container or a virtual machine.

以第一实例为Docker容器为例来说，上述沙箱环境的镜像文件可以是指Docker镜像文件，该Docker镜像文件可以是从Docker镜像仓库中预先下载的，如，可以是从Docker Hub公共镜像源预先下载的。需要说明的是，基于Docker镜像文件，通常可以启动多个Docker容器，该多个Docker容器之间是相互隔离的。此外，Docker镜像文件中还可以打包有第一浏览器以及依赖包，也即其中可以封装有第一浏览器。这里的第一浏览器可以是指任一浏览器，如，可以为Chrome浏览器或者Safari浏览器等等。当然，在实际应用中，上述Docker镜像文件中还可以封装有其它软件，如，拼图软件等等。Taking the first instance as a Docker container as an example, the image file of the aforementioned sandbox environment can refer to a Docker image file, which can be pre-downloaded from the Docker image warehouse, for example, it can be a public image from Docker Hub The source is pre-downloaded. It should be noted that based on the Docker image file, multiple Docker containers can usually be started, and the multiple Docker containers are isolated from each other. In addition, the first browser and dependent packages may also be packaged in the Docker image file, that is, the first browser may be packaged in the Docker image file. The first browser here can refer to any browser, for example, it can be a Chrome browser or a Safari browser. Of course, in practical applications, other software, such as puzzle software, can also be encapsulated in the above-mentioned Docker image file.

应理解，在第一实例为虚拟机时，虚拟机的镜像文件中也可以封装有第一浏览器以及其它软件等等，本说明书对此不作赘述。It should be understood that when the first instance is a virtual machine, the image file of the virtual machine may also be encapsulated with the first browser and other software, which will not be repeated in this specification.

此外，对于上述Docker镜像文件，当运行该Docker镜像文件时，可以启动一个Docker容器。在启动的Docker容器中，可以运行Docker镜像中封装的浏览器或者其它软件。浏览器或者其它软件在Docker容器中运行，就像在真实的物理机上运行一样。另外，对于虚拟机的镜像文件，当运行该虚拟机的镜像文件时，可以启动一台虚拟机。在启动的虚拟机中，也可以运行虚拟机的镜像文件中封装的浏览器或者其它软件。In addition, for the aforementioned Docker image file, when the Docker image file is run, a Docker container can be started. In the started Docker container, you can run the browser or other software packaged in the Docker image. The browser or other software runs in a Docker container, just like it runs on a real physical machine. In addition, for the image file of the virtual machine, when the image file of the virtual machine is running, a virtual machine can be started. In the started virtual machine, a browser or other software packaged in the image file of the virtual machine can also be run.

步骤206，在运行后的第一浏览器中，基于URL地址加载待截图网页。Step 206: Load the web page to be screenshot based on the URL address in the first browser after running.

也即在运行后的第一浏览器中，对待截图网页的页面内容进行渲染。That is, in the first browser after running, the page content of the web page to be captured is rendered.

需要说明的是，如果上述网页截图请求还包括用户自定义的截图规则，且该截图规则可以包括针对待截图网页所需执行的目标操作，那么在基于URL地址加载待截图网页之后，还可以确定在对待截图网页执行上述目标操作后的目标网页，并在上述第一浏览器中，通过目标网页代替最初加载的待截图网页。It should be noted that if the above web page screenshot request also includes user-defined screenshot rules, and the screenshot rule can include the target operation that needs to be performed on the web page to be screenshot, then after loading the web page to be screenshot based on the URL address, you can also determine The target webpage after the target operation is performed on the webpage to be screenshotted, and in the first browser, the target webpage is used to replace the initially loaded webpage to be screenshotted.

另外，如果获取不到上述用户自定义的截图规则，那么也可以基于默认的截图规则，来对待截图网页执行相应的操作。这里的默认的截图规则可以包括针对待截图网页所需执行的操作。此外，还可以包括截取区域或者截取像素范围等等。In addition, if the aforementioned user-defined screenshot rules cannot be obtained, then the corresponding operations can be performed on the screenshot webpage based on the default screenshot rules. The default screenshot rule here may include operations that need to be performed for the webpage to be screenshotted. In addition, it may also include a clipping area or a clipping pixel range, and so on.

当然，如果既获取不到用户自定义的截图规则，也没有默认的截图规则，那么也可以不对待截图网页执行任何操作。Of course, if neither user-defined screenshot rules nor default screenshot rules can be obtained, then no operation can be performed on the screenshot webpage.

步骤208，对待截图网页进行截图，以得到目标截图。Step 208: Take a screenshot of the webpage to be screenshot to obtain a target screenshot.

应理解，如果第一浏览器中的待截图网页被目标网页替代，那么这里可以是对目标网页进行截图，以得到目标截图。It should be understood that if the webpage to be screenshot is replaced by the target webpage in the first browser, then the target webpage may be screenshotted here to obtain the target screenshot.

对于待截图网页或者目标网页的截图过程，分如下两种情况进行讨论。For the screenshot process of the webpage to be screenshot or the target webpage, the discussion is divided into the following two situations.

第一种，当第一浏览器运行在Dcoker容器中时，由于Dcoker容器没有对应的UI界面，因此，可以直接基于第一浏览器内置的截图功能，对待截图网页或者目标网页进行截图。First, when the first browser is running in the Dcoker container, since the Dcoker container does not have a corresponding UI interface, it can directly take a screenshot of the webpage to be screenshot or the target webpage based on the screenshot function built in the first browser.

第二种，当第一浏览器运行在虚拟机中时，由于虚拟机具有对应的UI界面，因此，既可以基于第一浏览器内置的截图功能，对待截图网页或者目标网页进行截图。也可以基于独立的截图软件，对待截图网页或者目标网页进行截图。可以理解的是，当通过独立的截图软件，对待截图网页或者目标网页进行截图时，该独立的截图软件可以封装在虚拟机的镜像文件中。Second, when the first browser runs in a virtual machine, since the virtual machine has a corresponding UI interface, it is possible to take screenshots of the webpage to be screenshot or the target webpage based on the screenshot function built in the first browser. It can also be based on independent screenshot software to take screenshots of the webpage to be screenshot or the target webpage. It is understandable that when a screenshot is taken of the webpage to be screenshot or the target webpage through the independent screenshot software, the independent screenshot software can be encapsulated in the image file of the virtual machine.

需要说明的是，当上述截图规则还包括截取区域或者截取像素范围时，该步骤中对待截图网页或者目标网页进行截图的过程可以为：基于截取区域或者截取像素范围，对待截图网页或者目标网页进行截图，以得到目标截图。It should be noted that, when the above screenshot rule also includes the interception area or the interception pixel range, the process of taking the screenshot of the webpage to be screenshot or the target webpage in this step can be: based on the interception area or the interception pixel range, perform the screenshot for the webpage or the target webpage. Take a screenshot to get the target screenshot.

当然，如果截图规则中没有定义截取区域或者截取像素范围，那么可以默认对全部的网页页面进行截图等等，本说明书不作限定。Of course, if the screenshot rule does not define the interception area or the interception pixel range, then all web pages can be screenshots by default, etc., which is not limited in this manual.

步骤210，至少将目标截图存储到区块链网络中。In step 210, at least the target screenshot is stored in the blockchain network.

该存储过程具体可以为：向区块链网络的多个节点中任意的第一节点发送目标截图，以使第一节点在对目标截图的真实性验证通过后，对目标截图进行存储。还使第一节点向区块链网络中的其它节点广播目标截图。其它节点在接收到目标截图之后，也可以对目标截图的真实性进行验证，并在验证通过时，对目标截图进行存储。The storage process may specifically be: sending the target screenshot to any first node among the multiple nodes of the blockchain network, so that the first node stores the target screenshot after passing the authenticity verification of the target screenshot. It also makes the first node broadcast the target screenshot to other nodes in the blockchain network. After receiving the target screenshot, other nodes can also verify the authenticity of the target screenshot, and store the target screenshot when the verification passes.

关于上述对目标截图的真实性进行验证的过程，分如下两种情况进行讨论。Regarding the above process of verifying the authenticity of the target screenshot, the discussion will be divided into the following two situations.

第一，如果目标截图经由网页截图服务器使用预先存储的签名私钥进行了数字签名，且第一节点在本地预先存储了与上述签名私钥对应的公钥，那么上述真实性验证过程可以为：通过该公钥，对数字签名后的目标截图进行验签。First, if the target screenshot is digitally signed by the web screenshot server using the pre-stored signature private key, and the first node locally pre-stores the public key corresponding to the signature private key, then the authenticity verification process can be: The public key is used to verify the digitally signed target screenshot.

第二，如果目标截图未经过数字签名，或者第一节点在本地未存储与上述签名私钥对应的公钥，那么上述真实性验证过程可以为：向网页截图服务器发送截图查询请求，该截图查询请求用于指示网页截图服务器从相应的缓存记录中查找目标截图。当接收到用于指示查找到目标截图的查询结果时，目标截图的真实性验证通过。Second, if the target screenshot is not digitally signed, or the first node does not store the public key corresponding to the signature private key locally, the authenticity verification process can be: sending a screenshot query request to the web screenshot server, and the screenshot query The request is used to instruct the webpage screenshot server to find the target screenshot from the corresponding cache record. When the query result indicating that the target screenshot is found is received, the authenticity verification of the target screenshot is passed.

需要说明的是，第一节点在本地存储目标截图时，会针对该目标截图，生成对应的hash值，以用于标识该目标截图。在生成目标截图的hash值之后，第一节点可以通过网页截图服务器向用户返回该hash值，以便于用户可以基于该hash值，来提取上述目标截图。It should be noted that when the first node stores the target screenshot locally, it will generate a corresponding hash value for the target screenshot to identify the target screenshot. After the hash value of the target screenshot is generated, the first node may return the hash value to the user through the web page screenshot server, so that the user can extract the above-mentioned target screenshot based on the hash value.

以下具体说明下第一节点对目标截图的存储过程：创建与目标截图对应的新区块，该新区块包括区块头和区块体。向区块体中写入目标截图的图像数据。之后，生成与本区块体对应的hash值。该hash值即为与目标截图对应的hash值。向区块头中写入上一个区块体的哈希值(PreHash)，本区块体的哈希值(Hash)，以及时间戳(TimeStamp)。由此，就实现了目标截图在第一节点的本地存储。The following specifically describes the storage process of the first node on the target screenshot: creating a new block corresponding to the target screenshot, and the new block includes a block header and a block body. Write the image data of the target screenshot into the block body. After that, the hash value corresponding to the block body is generated. The hash value is the hash value corresponding to the target screenshot. Write the hash value of the previous block body (PreHash), the hash value of this block body (Hash), and the time stamp (TimeStamp) into the block header. As a result, the local storage of the target screenshot in the first node is achieved.

当然，在实际应用中，也可以基于智能合约来实现目标截图的存储。如，可以预先编写用于实现目标截图存储功能的智能合约，之后第一节点可以调用该智能合约。其中，该次调用的传入参数可以为目标截图的图像数据。需要说明的是，在智能合约实现目标截图存储的过程中，可以为目标截图生成相应的hash值。此外，在上述调用过程结束之后，第一节点对智能合约的调用过程可以作为一笔交易被记录下来。这里的交易记录可以包含上述hash值。从而第一节点可以将该笔交易存储到对应的区块中。之后，用户可以基于上述交易记录以及其中的hash值，来提取目标截图。Of course, in practical applications, the storage of target screenshots can also be realized based on smart contracts. For example, a smart contract for realizing the target screenshot storage function can be pre-written, and then the first node can call the smart contract. Among them, the incoming parameter of this call can be the image data of the target screenshot. It should be noted that in the process of storing the target screenshot by the smart contract, the corresponding hash value can be generated for the target screenshot. In addition, after the above-mentioned calling process ends, the calling process of the smart contract by the first node can be recorded as a transaction. The transaction record here can contain the above hash value. Therefore, the first node can store the transaction in the corresponding block. After that, the user can extract the target screenshot based on the transaction record and the hash value in it.

上述用户提取目标截图的过程具体可以为：第一节点接收用户的截图提取请求，该截图提取请求至少包括目标截图的hash值。基于hash值，查找目标截图。向用户返回目标截图。The above process of extracting the target screenshot by the user may specifically be as follows: the first node receives the user's screenshot extraction request, and the screenshot extraction request includes at least the hash value of the target screenshot. Based on the hash value, find the target screenshot. Return the target screenshot to the user.

为了确保用户所获取的目标截图的真实性，用户可以向区块链网络中的各节点发送截图提取请求；之后，如果超过一半的节点可以查找到该目标截图，那么就可以该目标截图是真实可信的。In order to ensure the authenticity of the target screenshot obtained by the user, the user can send a screenshot extraction request to each node in the blockchain network; after that, if more than half of the nodes can find the target screenshot, then the target screenshot can be real Credible.

还需要说明的是，由于网页的加载还可以受到加载时间的影响，也就是说明，针对同一网页，在不同的时间，其对应的加载结果可能不一致。因此，本方案中，在针对待截图网页或者目标网页进行截图之后，还可以获取执行截图操作时的截图时间。之后将目标截图和截图时间共同存储到区块链网络中。该两者的存储过程与目标截图的存储过程类似，在此不复赘述。It should also be noted that, since the loading of a webpage may also be affected by the loading time, that is to say, for the same webpage, the corresponding loading results may be inconsistent at different times. Therefore, in this solution, after taking a screenshot of the webpage to be screenshot or the target webpage, the screenshot time when the screenshot operation is performed can also be obtained. After that, the target screenshot and the screenshot time are stored together in the blockchain network. The stored procedures of the two are similar to those of the target screenshot, so I won’t repeat them here.

此外，应理解，本说明书实施例提供的方案不仅适用于网页截图的场景，理论上，只要是拥有可信、但是不稳定的第三方服务的场景都可以适用。如，可以适用于电子凭证存储的场景。这里的电子凭证可以包括但不限于视频流等等。In addition, it should be understood that the solution provided by the embodiment of this specification is not only applicable to the scene of webpage screenshots, but theoretically, it can be applicable as long as it has a credible but unstable third-party service. For example, it can be applied to the scenario of electronic voucher storage. The electronic vouchers here can include but are not limited to video streams and so on.

综上，本说明书实施例通过启动实例，可以保证网页渲染不会受之前、之后网页加载的影响。也即可以保证任务之间相互影响降低，同时可以复用处理器资源。此外，还可以将截图过程与存储过程解耦，使得截图资源可以动态扩容。最后，网页截图后直接接入区块链网络，可以保证网页截图结果保鲜，使得取到的内容可信。In summary, the embodiment of this specification can ensure that the rendering of the webpage will not be affected by the loading of the webpage before and after by starting the example. That is, it can ensure that the mutual influence between tasks is reduced, and processor resources can be reused at the same time. In addition, the screenshot process can be decoupled from the stored procedure, so that the screenshot resource can be dynamically expanded. Finally, after the screenshot of the web page is directly connected to the blockchain network, the results of the screenshot of the web page can be kept fresh and the content obtained can be trusted.

图3为本说明书一个实施例提供的基于区块链网络的数据存储方法流程图。所述方法的执行主体可以为图1的区块链网络中多个节点中任意的第一节点。如图3所示，该方法具体可以包括步骤302至308。Fig. 3 is a flowchart of a data storage method based on a blockchain network provided by an embodiment of this specification. The execution subject of the method may be any first node among multiple nodes in the blockchain network of FIG. 1. As shown in FIG. 3, the method may specifically include steps 302 to 308.

步骤302，接收网页截图服务器发送的目标截图。Step 302: Receive the target screenshot sent by the webpage screenshot server.

这里的目标截图即为上述实施例中所提到的目标截图，本说明书对此不复赘述。The target screenshot here is the target screenshot mentioned in the above embodiment, which will not be repeated in this specification.

步骤304，对目标截图进行真实性验证。Step 304: Perform authenticity verification on the target screenshot.

第二，如果目标截图未经过数字签名，或者第一节点在本地未存储与上述签名私钥对应的公钥，那么上述真实性验证过程可以为：向网页截图服务器发送截图查询请求，该截图查询请求用于指示网页截图服务器从相应的缓存记录中查找目标截图。当接收到用于指示查找到目标截图的查询结果时，目标截图的真实性验证通过。Second, if the target screenshot is not digitally signed, or the first node does not store the public key corresponding to the signature private key locally, the authenticity verification process can be: sending a screenshot query request to the web screenshot server, and the screenshot query The request is used to instruct the webpage screenshot server to find the target screenshot from the corresponding cache record. When the query result indicating that the target screenshot is found is received, the authenticity verification of the target screenshot passes.

步骤306，在验证通过后，对目标截图进行存储。Step 306: After the verification is passed, the target screenshot is stored.

步骤308，向多个节点中的其它节点发送目标截图，以使其它节点对目标截图进行存储。Step 308: Send the target screenshot to other nodes among the multiple nodes, so that the other nodes store the target screenshot.

需要说明的是，其它节点在接收到目标截图之后，也可以先对目标截图的真实性进行验证，并在验证通过之后，对目标截图进行存储。It should be noted that after receiving the target screenshot, other nodes may also verify the authenticity of the target screenshot first, and store the target screenshot after the verification is passed.

需要说明的是，第一节点在本地存储目标截图时，会针对该目标截图，生成对应的hash值，以用于标识该目标截图。在生成目标截图的hash值之后，第一节点可以通过网页截图服务器向用户返回该hash值，以便于用户可以基于该hash值，来提取上述目标截图。It should be noted that when the first node stores the target screenshot locally, it will generate a corresponding hash value for the target screenshot to identify the target screenshot. After generating the hash value of the target screenshot, the first node can return the hash value to the user through the web page screenshot server, so that the user can extract the target screenshot based on the hash value.

需要说明的是，本说明书实施例提供的基于区块链网络的数据存储方法不仅可以适用于网页截图存储的场景，此外，还可以视频流等电子凭证存储的场景，本说明书对此不作限定。It should be noted that the blockchain network-based data storage method provided in the embodiments of this specification is not only applicable to scenarios where webpage screenshots are stored, but also scenarios where electronic vouchers such as video streams are stored, which is not limited in this specification.

综上，本说明书实施例提供的基于区块链网络的数据存储方法可以确保所存储数据的真实性和长期保真。In summary, the data storage method based on the blockchain network provided by the embodiments of this specification can ensure the authenticity and long-term fidelity of the stored data.
