请参阅图2，图2是本发明实施例提供一种分布式***数据共享方法的流程示意图。如图2所示，分布式***数据共享方法S200包括：Please refer to FIG. 2, which is a schematic flowchart of a data sharing method for a distributed system according to an embodiment of the present invention. As shown in FIG. 2, the distributed system data sharing method S200 includes:
S21、接收第一设备发送的第一数据共享请求，第一数据共享请求携带有第二设备的身份信息；S21. Receive a first data sharing request sent by a first device, where the first data sharing request carries identity information of a second device;
在本实施例中，第一设备保存有设备权限列表，设备权限列表预存有若干设备的身份信息，其中包括第二设备的身份信息，任意两个设备的身份信息皆不同，每个设备的身份信息皆对应有通讯地址。In this embodiment, the first device stores a device permission list, and the device permission list pre-stores the identity information of several devices, including the identity information of the second device. The identity information of any two devices is different, and the identity of each device is different. The information corresponds to the correspondence address.
第一设备需要共享第二设备的屏幕内容时，第一设备将第二设备的身份信息封装成第一数据共享请求，第一设备向节点服务器发送第一数据共享请求，以使节点服务器根据第一数据共享请求中的第二设备的身份信息，查找出所述第二设备的通讯地址。When the first device needs to share the screen content of the second device, the first device encapsulates the identity information of the second device into a first data sharing request, and the first device sends the first data sharing request to the node server, so that the node server The identity information of the second device in a data sharing request is used to find the communication address of the second device.
在一些实施例中，节点服务器检测到新增设备加入数据共享分布式***时，节点服务器将新增设备的身份信息广播于数据共享分布式***，每个设备接收到新增设备的身份信息时，都会自动更新自身维护的设备权限列表。In some embodiments, when the node server detects that the newly added device joins the data sharing distributed system, the node server broadcasts the identity information of the newly added device to the data sharing distributed system, and when each device receives the identity information of the newly added device , Will automatically update the device permission list maintained by itself.
S22、根据第二设备的身份信息，获取显示于第二设备的屏幕内容的文件格式以及播放起始点；S22. Acquire a file format and a playback starting point of the screen content displayed on the second device according to the identity information of the second device.
在本实施例中，节点服务器同样维护着与各个设备相同的设备权限列表。节点服务器获取设备权限列表，判断设备权限列表是否存在与第二设备的身份信息匹配的身份信息，若不存在，不响应第一数据共享请求，若存在，根据第二设备的身份信息，获取显示于第二设备的屏幕内容的文件格式以及播放起始点，例如，节点服务器从设备权限列表中遍历出与第二设备的身份信息相对应的通讯地址，并根据第二设备的通讯地址访问第二设备。访问第二设备时，节点服务器向第二设备发送内容获取请求，该内容获取请求用于指示第二设备向节点服务器返回第二设备显示屏幕当前显示的屏幕内容的文件格式以及播放起始点，于是，第二设备根据内容获取请求，向节点服务器返回屏幕内容的文件格式以及播放起始点。In this embodiment, the node server also maintains the same device permission list as each device. The node server obtains the device permission list and determines whether there is identity information matching the identity information of the second device in the device permission list. If it does not exist, it does not respond to the first data sharing request. If it does, it obtains a display based on the identity information of the second device. The file format and playback start point of the screen content of the second device, for example, the node server traverses the communication address corresponding to the identity information of the second device from the device permission list, and accesses the second device according to the communication address of the second device device. When accessing the second device, the node server sends a content acquisition request to the second device, and the content acquisition request is used to instruct the second device to return to the node server the file format of the screen content currently displayed on the display screen of the second device and the playback start point. The second device returns the file format of the screen content and the playback starting point to the node server according to the content acquisition request.
屏幕内容包括各类格式视频文件、各类格式音频文件或各类格式编辑文本等等，例如，视频文件的格式包括wmv、asf、asx、rm、rmvb、mp4、3gp、mov、m4v、avi、dat、mkv、flv、vob等等，音频文件的格式包括ACT、REC、VY1、VY2、VY3、VY4、SC4、DVF、MSC、WMA、MP3、WAV等等。Screen content includes various formats of video files, various formats of audio files or various formats of edited text, etc. For example, the format of video files includes wmv, asf, asx, rm, rmvb, mp4, 3gp, mov, m4v, avi, dat, mkv, flv, vob, etc. The formats of audio files include ACT, REC, VY1, VY2, VY3, VY4, SC4, DVF, MSC, WMA, MP3, WAV, and so on.
播放起始点为在第二设备响应于内容获取请求时，当前屏幕内容所在的播放时间点，例如，屏幕内容为视频文件，该视频文件的播放时长为60分钟，当该视频文件在第二设备播放32分钟时，第二设备响应于内容获取请求，此时的播放时间点为第32分钟。The playback start point is the playback time point at which the current screen content is located when the second device responds to the content acquisition request. For example, the screen content is a video file, and the playback time of the video file is 60 minutes. When playing for 32 minutes, the second device responds to the content acquisition request, and the playback time point at this time is the 32nd minute.
S23、向第一设备返回第二设备的屏幕内容的文件格式以及播放起始点，以使第一设备根据屏幕内容的文件格式返回文件播放请求；S23: Return the file format of the screen content of the second device and the playback start point to the first device, so that the first device returns a file playback request according to the file format of the screen content;
在本实施例中，当节点服务器接收到第二设备返回的屏幕内容的文件格式以及播放起始点，节点服务器便向第一设备转发第二设备的屏幕内容的文件格式以及播放起始点。第一设备根据屏幕内容的文件格式，判断自身是否安装有用于打开该屏幕内容的应用程序，第一设备将判断结果封装于文件播放请求，并向节点服务器发送文件播放请求。并且，第一设备还记录第二设备的屏幕内容的播放起始点。In this embodiment, when the node server receives the file format and the playback start point of the screen content returned by the second device, the node server forwards the file format and the playback start point of the screen content of the second device to the first device. The first device determines whether an application program for opening the screen content is installed according to the file format of the screen content, the first device encapsulates the determination result in a file playback request, and sends the file playback request to the node server. In addition, the first device also records a playback start point of the screen content of the second device.
举例而言，判断结果包括存在用于打开屏幕内容的应用程序和不存在用于 打开屏幕内容的应用程序，例如，第二设备显示屏幕的当前屏幕内容为mov格式视频文件，然而，第一设备并未安装有用于打开mov格式视频文件的应用程序，于是，该判断结果为不存在用于打开屏幕内容的应用程序。相反，当第一设备安装有用于打开mov格式视频文件的应用程序，于是，该判断结果为存在用于打开屏幕内容的应用程序。For example, the judgment result includes the existence of an application for opening the screen content and the absence of an application for opening the screen content. For example, the current screen content of the display screen of the second device is a mov format video file. An application for opening a mov format video file is not installed, so the determination result is that there is no application for opening the screen content. In contrast, when the first device is installed with an application program for opening a mov format video file, the determination result is that there is an application program for opening the screen content.
S24、根据文件播放请求，向第一设备发送屏幕内容，以使第一设备根据播放起始点播放屏幕内容。S24. Send the screen content to the first device according to the file playback request, so that the first device plays the screen content according to the playback start point.
在本实施例中，节点服务器根据文件播放请求，适应性地向第一设备发送屏幕内容，以使第一设备在播放起始点处播放屏幕内容。In this embodiment, the node server adaptively sends screen content to the first device according to the file playback request, so that the first device plays the screen content at the playback starting point.
在一些实施例中，第一设备根据播放起始点播放屏幕内容的过程中，其还可以获取网络延迟时间，在播放起始点处按照预设播放速度快进与网络延迟时间相对应的播放进度，以使第一设备更有效地共享第二设备的屏幕内容。In some embodiments, during the process of playing the screen content according to the playback start point, the first device may also obtain the network delay time, and fast forward the playback progress corresponding to the network delay time at the playback start point according to a preset playback speed. This allows the first device to more effectively share the screen content of the second device.
综上，节点服务器能够根据屏幕内容的文件格式向第一设备发送屏幕内容，使得第一设备能够成功地打开屏幕内容，降低共享失败率，从而提高***运行的可靠性。In summary, the node server can send the screen content to the first device according to the file format of the screen content, so that the first device can successfully open the screen content, reduce the sharing failure rate, and thereby improve the reliability of system operation.
如前所述，判断结果包括存在用于打开屏幕内容的应用程序和不存在用于打开屏幕内容的应用程序，相应的，文件播放请求包括播放成功请求与播放失败请求。As described above, the determination result includes the existence of an application program for opening the screen content and the absence of an application program for opening the screen content. Accordingly, the file playback request includes a playback success request and a playback failure request.
承接上述例子，虽然第一设备未安装有用于打开mov格式视频文件的应用程序，但是第一设备安装有用于打开avi格式视频文件的应用程序，当将mov格式视频文件转换成avi格式视频文件时，第一设备便能够成功地共享第二设备的屏幕内容。因此，在一些实施例中，请参阅图3，S24包括：Following the above example, although the first device is not installed with an application for opening a mov format video file, the first device is installed with an application for opening an avi format video file. When the mov format video file is converted into an avi format video file , The first device can successfully share the screen content of the second device. Therefore, in some embodiments, referring to FIG. 3, S24 includes:
S241、确定文件播放请求的类型，若是播放成功请求，跳转至S242；若是播放失败请求，跳转至S244；S241. Determine the type of the file playback request. If the playback is successful, skip to S242; if the playback fails, skip to S244;
S242、若是播放成功请求，向第二设备发送第二数据共享请求，以使第二设备根据第二数据共享请求返回屏幕内容的地址；S242. If the playback is successful, send a second data sharing request to the second device, so that the second device returns the address of the screen content according to the second data sharing request;
在S242中，第一设备存在用于打开屏幕内容的应用程序，节点服务器根据第一设备返回的播放成功请求，向第二设备发送第二数据共享请求，其中，该第二数据共享请求用于指示第二设备返回屏幕内容的地址。屏幕内容可以为 第二设备在线观看的内容，亦可以为第二设备本地存储的内容，当屏幕内容为在线观看的内容时，该屏幕内容的地址为URL地址(Uniform Resource Locator，统一资源定位符)。当屏幕内容为本地存储的内容，该屏幕内容的地址为绝对地址。In S242, there is an application for opening the screen content on the first device, and the node server sends a second data sharing request to the second device according to the playback success request returned by the first device, where the second data sharing request is used for An address that instructs the second device to return the screen content. The screen content can be the content viewed online by the second device or the content stored locally by the second device. When the screen content is viewed online, the address of the screen content is a URL address (Uniform Resource Locator, Uniform Resource Locator). ). When the screen content is locally stored content, the address of the screen content is an absolute address.
在一些实施例中，当第二设备当前播放的屏幕内容为注册会员方可观看的内容时，第二设备不仅返回屏幕内容的地址，而且还返回第二设备的会员注册账号绑定的亲情账号，以使第一设备根据亲情账号登录上屏幕内容所在的网页，并成功与第二设备共享屏幕内容。In some embodiments, when the screen content currently played by the second device is content that can be viewed by registered members, the second device returns not only the address of the screen content, but also the family account bound to the member registration account of the second device. To enable the first device to log in to the webpage where the screen content is located according to the family account and successfully share the screen content with the second device.
S243、向第一设备发送屏幕内容的地址，以使第一设备根据屏幕内容的地址获取屏幕内容；S243. Send the address of the screen content to the first device, so that the first device obtains the screen content according to the address of the screen content.
S244、若是播放失败请求，根据播放失败请求，将屏幕内容转换成可由第一设备播放的目标文件，并向第一设备发送目标文件。S244. If the playback failure request, according to the playback failure request, convert the screen content into a target file that can be played by the first device, and send the target file to the first device.
在S244中，承接上述例子，节点服务器将mov格式视频文件转换成avi格式视频文件，该avi格式视频文件为目标文件。In S244, following the above example, the node server converts the mov format video file into an avi format video file, and the avi format video file is the target file.
在一些实施例中，播放失败请求携带有第一设备的文件格式。请参阅图4，S244包括：In some embodiments, the playback failure request carries a file format of the first device. Referring to Figure 4, S244 includes:
S2441、根据播放失败请求，向第二设备发送第二数据共享请求，以使第二设备根据第二数据共享请求返回屏幕内容的地址；S2441. Send a second data sharing request to the second device according to the playback failure request, so that the second device returns the address of the screen content according to the second data sharing request.
S2442、根据屏幕内容的地址，下载屏幕内容；S2442. Download the screen content according to the address of the screen content.
S2443、将屏幕内容转换成匹配第一设备的文件格式的目标文件。S2443: Convert the screen content into an object file that matches the file format of the first device.
因此，第一设备能够可靠地、成功地共享第二设备的屏幕内容。Therefore, the first device can reliably and successfully share the screen content of the second device.
一般，在线视频的播放流畅性低于本地视频的播放流畅性。在一些实施例中，屏幕内容已被下载并预存于节点服务器，第二设备从节点服务器获取视频并将该视频播放的流畅性会高于在线播放视频的流畅性。因此，为了提高第二设备播放视频的流畅性，首先，节点服务器在检测到第二设备的屏幕内容为在线视频时，向第二设备发送连接断开请求，以使第二设备断开在线连接，并与节点服务器建立新连接。其次，以播放起始点为起始点，节点服务器向第二设备推送目标文件的后续内容，该后续内容的起始时间点为播放起始点。Generally, the smoothness of online video playback is lower than that of local video. In some embodiments, the screen content has been downloaded and pre-stored in the node server, and the second device obtains the video from the node server and plays the video more smoothly than when playing the video online. Therefore, in order to improve the smoothness of the video played by the second device, first, when the node server detects that the screen content of the second device is an online video, it sends a connection disconnection request to the second device to disconnect the second device from the online connection. And establish a new connection with the node server. Second, with the playback start point as the starting point, the node server pushes the subsequent content of the target file to the second device, and the start time point of the subsequent content is the playback start point.
在一些实施例中，节点服务器还可以获取网络延迟时间，在播放起始点处 按照预设播放速度快进与网络延迟时间相对应的播放进度，以使第二设备更有效地播放屏幕内容。In some embodiments, the node server may further obtain the network delay time, and fast forward the playback progress corresponding to the network delay time at the playback start point according to a preset playback speed, so that the second device plays the screen content more efficiently.
