The target server is an embedded server (such as an embedded web server) pre-embedded in the first device, and the target server is used for controlling the application program on the first device. In order to enable the target server to control the application program on the first device, the application program on the first device may be developed in advance based on the specification of the target server, and each application program needs to report its own package name, class name and parameters of the opened capability, call type (e.g., activity, broadcast), and register its own capability on the target server. The interface information refers to a port address of the target server.

S102, sending the interface information to a second device, so that when the second device accesses the first device, the target server is accessed through the interface information, and the application program on the first device is controlled through the target server.

In this embodiment, the second device is a control end of a remote control, such as a smart phone. After the interface information is sent to the second device, when the second device accesses the first device, the target server can be accessed through the interface information, and then the application program on the first device is controlled through the target server.

As shown in fig. 2, a web server APP (target server) is embedded in a television, APP1-8 is an application program developed based on the specification of the web server APP on the television, each APP needs to report its own package name, class name and parameter of open capability, and call type (e.g., activity, broadcast), so as to register its own capability on the web server APP, so that a control end can access the web server APP through interface information of the web server APP, and further control APP1-8 on the television through the web server APP.

In the embodiment of the application, first, interface information of a target server is obtained, wherein the target server is an embedded server which is embedded into first equipment in advance, and the target server is used for controlling an application program on the first equipment; and then, sending the interface information to the second equipment. When the second device accesses the first device, the target server can be accessed through the interface information, and the application program on the first device is controlled through the target server. According to the scheme, the application program on the first equipment can be controlled through the embedded server only by exposing the port of the embedded server on the first equipment, and the port does not need to be exposed by each application program on the first equipment, so that the port resource is saved.

In another embodiment of the present application, as shown in fig. 3, the method may further include the steps of:

s201, acquiring the device information sent by the first device.

In the embodiment of the present application, the device information may include, but is not limited to, a device ID. The first device sends its device information to the server before establishing the remote control connection.

After receiving the device information, the server may generate access information corresponding to the first device based on the device information.

S203, sending the access information to the second device, so that the second device accesses the first device through the access information.

Determining an agent node with the flow data smaller than a preset threshold value as a target node; the access information is distributed to the target node for processing. When the traffic processed by the plurality of proxy nodes is smaller than the preset threshold, the proxy node with the smallest processed traffic can be selected as the target node from the plurality of proxy nodes.

As shown in fig. 4, a Frp (fast reverse proxy) client (Frp client) is configured in the first device ("device" in the figure) in advance. When the Frp client is started, the Frp client may send device information of the first device to the server. After a server (in the figure, "agent") receives the equipment information and generates access information according to the equipment information, an agent node (frp server node) meeting preset conditions is distributed to the access information.

By the scheme, the agent node with the flow data smaller than the preset threshold value can be determined as the target node, and the access information is distributed to the target node for processing. The access information is prevented from being distributed to the proxy node which is already processing a lot of traffic, thereby improving the processing efficiency of the access information.

In yet another embodiment of the present application, the method may further comprise the steps of:

step one, receiving an access request of the second device, wherein the access request carries the access information;

and step two, when the access request meets the preset access condition, determining a target node corresponding to the access information so that the second device accesses the first device through the target node.

In the embodiment of the application, the access request is used for requesting access to the first device, and carries access information, when the access request of the second device is received, whether the access request is legal or not needs to be judged through authentication information in the access information, and when the authentication information is correct, the access request is determined to be legal, that is, the access request meets the preset access condition. And determining a target node corresponding to the access information so that the second device accesses the first device through the target node.

As shown in fig. 5, a control interface of the second device (the "user" in the figure) is opened, the access request is sent to the server (the "proxy" in the figure), after receiving the access request, the server allocates the access request to a target node corresponding to the access information in the access request, the target node processes the access request, so that the second device (the "user" in the figure) accesses the first device (the "device" in the figure), and after the first device (the "device" in the figure) executes a corresponding operation according to an instruction of the second device (the "user" in the figure), the execution result is returned to the second device (the "user" in the figure).

In the embodiment of the application, the second device can determine the corresponding target node through the access information, and then access the first device through the target node, so that the access process is simple and efficient, and the access to the first device by using the proxy node which is already processing a lot of flows can be avoided, thereby improving the access efficiency.

In yet another embodiment of the present application, the method may further comprise the steps of:

step one, receiving media information sent by the second equipment.

And step two, generating a control link based on the media information.

And step three, the control link is sent to the first equipment, so that the first equipment processes the media information based on the control link.

In the embodiment of the present application, the media information refers to media content stored or collected by the second device, such as content such as pictures or videos. After receiving the media information sent by the second device, the media information may be stored in the server, and a control link may be generated based on the media information and sent to the first device. After receiving the control link, the first device may process the media information through the control link, for example, when the media information is a video, the video may be played.

In this embodiment of the application, a control link may be generated based on the media information sent by the second device, and the control link is sent to the first device, so that the first device processes the media information based on the control link. Therefore, the first device is not required to store the media information, and the storage resource of the first device is occupied.

In yet another embodiment of the present application, the method may further comprise the steps of:

step one, acquiring image information of an object acquired by the first equipment.

And secondly, determining corresponding control information and a target application program corresponding to the control information based on the image information.
