Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
For the convenience of understanding of the embodiments of the present invention, the following description will be further explained with reference to specific embodiments, which are not to be construed as limiting the embodiments of the present invention.
In the application, as shown in fig. 1, in the application scenario diagram shown in fig. 1, the control terminal is a mobile phone, and may also be other terminals, for example, a computer, a PDA, and a tablet. The internet of things equipment is a network camera, and the cloud server can be a specific server or a server cluster.
According to the technical scheme, the control terminal receives a target Internet of things equipment access request input by a user and sends the target Internet of things equipment access request to a cloud server; the Web process in the cloud server sends the user interface code corresponding to the target Internet of things equipment access request to the control terminal so that the control terminal can execute the user interface code; the control terminal receives the user interface code and sends an acquisition request for executing the required data of the user interface code to the cloud server; the cloud service end Web process receives the acquisition request, forwards the acquisition request to a cloud service end VPN process, and sends the acquisition request to the target Internet of things equipment through the cloud service end VPN process; the corresponding application program in the target Internet of things equipment executes the acquisition request to obtain data required for executing the user interface code, and the data required for executing the user interface code is sent to a cloud server; the cloud service end VPN process receives the required data of the user interface code, forwards the required data of the user interface code to the cloud service end Web process, and sends the required data of the user interface code to the control terminal; and the control terminal executes the user interface codes to display the required data for executing the user interface codes. Therefore, the user can conveniently and safely remotely control the target Internet of things equipment at the control terminal.
For further explanation of the present application, the following examples are provided to illustrate the present application:
as shown in fig. 2, an interactive flow diagram of the method for controlling an internet of things device according to the present application may specifically include the following steps:
s201, a control terminal receives a target Internet of things equipment access request input by a user;
in the application, a user wants to access a webcam driven by Jeejio, and the user can access a website by using a control terminal: https:// jeejio. Com/zlei/webcam/monitor/pic _ now/, for example, the above-mentioned website is accessed using a mobile phone as shown in fig. 1, in this URL, "webcam" is an alias of the user to the webcam; "monitor" is the name of an application running on the webcam; the "pic _ now" is a "sub-page" in the "minor" app, and the control terminal may receive a target internet of things device access request input by the user, where the target internet of things device access request may be a URL as described above.
S202, the control terminal sends the target Internet of things equipment access request to a cloud server;
the control terminal sends the target internet of things device access request to a cloud server, for example, the URL (https:// jeejio. Com/zlei/webcam/monitor/pic _ now /) can be sent to the cloud server, specifically to a Web process in the cloud server.
S203, the Web process in the cloud service end sends the user interface code corresponding to the target Internet of things equipment access request to the control terminal, so that the control terminal executes the user interface code;
after the Web process in the cloud service end receives the target Internet of things equipment access request, the Web process in the cloud service end sends a user interface code corresponding to the target Internet of things equipment access request to the control terminal, so that the control terminal executes the user interface code.
For example, a Web process in the cloud service side sends an HTML5 user interface code corresponding to the target internet of things device access request to the mobile phone shown in fig. 1. The HTML5 user interface code is written specifically for the network camera 'monitor' app. Typically, this code is part of a third party application developed by a third party developer. The third party application needs to have its user interface code on the server side during installation so that any control device can retrieve it when accessing the relevant application.
S204, the control terminal receives the user interface code and sends an acquisition request for executing the required data of the user interface code to the cloud server;
the control terminal receives the user interface code, and since the control terminal needs to acquire data from the target internet of things device in the process of executing the user interface code, an acquisition request for executing the data of the user interface code needs to be sent to the cloud server.
For example, as shown in fig. 1, the cell phone browser needs to obtain more data from the webcam during the execution of the HTML5 user interface code. For example, part of the HTML5 code needs to access the latest image captured by the web camera, with a URL https:// jeejio. Com/zlei/webcam/monitor/data _ now. This is to require the webcam to execute a piece of code and return the required image.
S205, the cloud service end Web process receives the acquisition request, forwards the acquisition request to a cloud service end VPN process, and sends the acquisition request to the target Internet of things equipment through the cloud service end VPN process;
the cloud service end Web process receives the acquisition request, forwards the acquisition request to the cloud service end VPN process, and sends the acquisition request to the target Internet of things equipment through the cloud service end VPN process, wherein the specific implementation mode is as follows:
the cloud service end Web process receives the acquisition request, searches a VPN subnet address of the target Internet of things equipment in a local database, forwards the acquisition request to the cloud service end VPN process according to the VPN subnet address, and sends the acquisition request to the target Internet of things equipment.
For example, as shown in fig. 1, when the cloud server Web process receives the acquisition request, it needs to first search the database for this specific device, i.e. the webcam of zlei, which is located on the VPN subnet of 10.0.0.1. Then the cloud service end Web process forwards the URL request to the cloud service end VPN process which is in charge of the VPN. These VPNs are secure tunnels that allow the cloud service to interact with the internet of things devices. Where a generic VPN proxy service is not provided here. The VPNs cannot be used for general network access of third-party application programs, can only be used for the cloud service side and the Internet of things device to communicate with each other, and are security tunnels for the interconnection of the cloud service side and the Internet of things device, as shown in FIG. 1, a webcam device of zlei is located at a position with a VPN address of 10.0.0.17, and therefore, URL https:// jeejio. Com/zlei/webcam/monitor/data _ now of an initial control side can be expressed as http://10.0.0.17/monitor/data _ now.
S206, the corresponding application program in the target Internet of things equipment executes the acquisition request to obtain the required data for executing the user interface code;
the corresponding application program in the target internet of things device executes the acquisition request to obtain the required data for executing the user interface code, and the specific implementation mode is as follows:
receiving the acquisition request by a VPN client process in the target Internet of things equipment, wherein the VPN client process is used for receiving the request from the cloud server; the VPN client process in the target Internet of things equipment forwards the acquisition request to a Web server process in the target Internet of things equipment; the Web server process in the target Internet of things equipment forwards the acquisition request to a corresponding application program; and executing the acquisition request by the corresponding application program in the target Internet of things equipment to obtain the required data for executing the user interface code.
The Web server process in the target internet of things device forwards the acquisition request to the corresponding application program, and the specific implementation manner is as follows:
extracting key fields from the acquisition request by a Web server process in the target Internet of things equipment; and forwarding the acquisition request to a corresponding application program according to the key field.
In addition, the corresponding application program in the target internet of things device executes the acquisition request to obtain the required data for executing the user interface code, and the specific implementation manner is as follows:
corresponding application programs in the target Internet of things equipment analyze fields related to the corresponding application programs from the acquisition requests; and executing the acquisition request according to the field related to the user interface code to obtain the required data for executing the user interface code.
For example, as shown in fig. 1, a VPN client process is running on the network camera, and is configured to receive a request from the cloud server, and then forward the request to a local Web server process named "httpd" running on the network camera, where all communications related to the cloud server need to be routed through the "httpd" running on the internet of things device. Therefore, the httpd process needs to forward the request sent by the cloud server to a specific third-party application program running on the network camera. The "minor" field in the URL is used to index the response app, which is used to find "app 1" and its corresponding process.
The "minor" app on the webcam device is an application developed by a third party, which will eventually receive the request sent, and the only part of the URL related to the "minor" app is "data _ now". The "minor" app, upon receiving the "data _ now" request, will execute the request by capturing the current image and send the response to the local "httpd".
S207, the corresponding application program in the target Internet of things equipment sends the data required for executing the user interface code to a cloud server;
the corresponding application program in the target internet of things equipment sends the required data for executing the user interface code to the cloud server, and the specific implementation mode is as follows:
the corresponding application program in the target Internet of things equipment forwards the data required for executing the user interface code to a Web server process in the target Internet of things equipment; the Web server process in the target Internet of things equipment forwards the required data for executing the user interface code to a VPN client process in the target Internet of things equipment; and the VPN client process in the target Internet of things equipment sends the required data for executing the user interface code to a cloud server.
For example, as shown in fig. 1, the app sends a response to a local "httpd", the local "httpd" forwards the response to the VPN client process running on the network camera, and the VPN client process running on the network camera sends the response to the cloud server.
S208, the cloud service end VPN process receives the required data of the user interface code, forwards the required data of the user interface code to the cloud service end Web process, and sends the required data of the user interface code to the control terminal;
and the cloud service end VPN process receives the required data of the user interface code, forwards the required data of the user interface code to the cloud service end Web process, and sends the required data of the user interface code to the control terminal.
For example, as shown in fig. 1, the VPN client process on the network camera forwards the response to the VPN process operated by the cloud server, the VPN process operated by the cloud server forwards the response to the Web process operated by the cloud server, and the Web process operated by the cloud server sends the response to the mobile phone.
S209, the control terminal executes the user interface code to display the required data for executing the user interface code.
And the control terminal receives the data required for executing the user interface code, executes the user interface code to display the data required for executing the user interface code, and finishes controlling the target Internet of things equipment.
For example, as shown in fig. 1, when the mobile phone receives the data required for executing the user interface code, the HTML5 code running in the mobile phone will continue to be executed, and finally the current image captured by the network camera is displayed.
According to the method, the VPN tunnel between the cloud server and the Internet of things equipment ensures that the message can safely reach the Internet of things equipment through the wide area network, and the message is communicated based on the URL.
According to the technical scheme provided by the embodiment of the application, the control terminal receives a target Internet of things equipment access request input by a user and sends the target Internet of things equipment access request to the cloud server; the Web process in the cloud server sends the user interface code corresponding to the target Internet of things equipment access request to the control terminal so that the control terminal can execute the user interface code; the control terminal receives the user interface code and sends an acquisition request for executing the required data of the user interface code to the cloud server; the cloud service end Web process receives the acquisition request, forwards the acquisition request to a cloud service end VPN process, and sends the acquisition request to the target Internet of things equipment through the cloud service end VPN process; the corresponding application program in the target Internet of things equipment executes the acquisition request to obtain data required for executing the user interface code, and the data required for executing the user interface code is sent to a cloud server; the cloud service end VPN process receives the required data of the user interface code, forwards the required data of the user interface code to the cloud service end Web process, and sends the required data of the user interface code to the control terminal; and the control terminal executes the user interface codes to display the required data for executing the user interface codes.
