The method comprises the following steps:
step 101, a first network server receives an inquiry request initiated by a browser of a first terminal device (for example, a mobile phone), wherein the inquiry request is used for requesting a URL address of a terminal device in a local area network where the first terminal device (for example, the mobile phone) is located. The step and subsequent steps 102 and 103 may be specifically executed by a WEB server on the first network server, where the step may be that the WEB server on the first network server receives, by using a WEB interface, a query request initiated by a browser of the first terminal (e.g., a mobile phone) device.
Before this step 101, a WEB server on a first network server may provide a WEB page program to a first terminal (e.g., a mobile phone) device by using a WEB interface, or a WEB server on another network server (e.g., a second network server) may provide a WEB page program to a first terminal (e.g., a mobile phone) device by using a WEB interface, where the WEB page program includes: and a program for controlling the browser of the first terminal (such as a mobile phone) to send the query request. The WEB page program may further include: and/or, controlling the browser of the first terminal (such as a mobile phone) device to store the program of the internal URL address which is successfully connected, and controlling the browser of the first terminal (such as a mobile phone) device to connect with the stored internal URL address when the first terminal (such as a mobile phone) device is not connected for the first time. The internal URL in this embodiment and the subsequent embodiments at least includes an intranet IP address of the terminal device in the local area network, and specifically, the internal URL includes the intranet IP address or a domain name, a file directory address, and may further include an access parameter, and the like.
Step 102, the first network server obtains a public network IP address of a local area network where a first terminal (for example, a mobile phone) device is located. Wherein the public network IP address is a public network IP address of the local area network.
Before step 101, the first terminal (e.g., a mobile phone) device establishes an HTTP connection with the first network server, and in this step, the first network server may call some interfaces to query according to the established HTTP connection, and how to obtain the public network IP address through the established HTTP connection is a relatively mature technology, which is not described herein again.
The query request is initiated by a browser of a first terminal (e.g., a mobile phone) device and forwarded to a first network server via a network device, in another embodiment, the query request is added to a public network IP address of a local area network by the network device when being forwarded by the network device, so that the query request carries the public network IP address when reaching the first network server, and in this step, the network server parses the public network IP address from the query request. Wherein, the network device may include at least one of a router, a switch, and a gateway.
And 103, the first network server acquires internal URL addresses of other terminal equipment in the local area network corresponding to the public network IP address according to the public network IP address of the local area network. The other terminal devices in the local area network are terminal devices in the local area network except the first terminal device, such as a set top box. The internal URL address is a URL address which can be accessed in the local area network, and the internal URL at least comprises intranet IP addresses of other terminal equipment in the local area network.
In the step, the first network server uses the public network IP address as an index to find the corresponding relation and obtains at least one URL address corresponding to the public network IP address, such as a URL address of a set-top box.
Step 104, the first network server sends a response message of the query request to the first terminal (e.g. mobile phone) device, where the response message includes: and the internal URL address of the terminal equipment in the local area network.
Wherein, the step may be that the WEB server in the first network server sends the response message through a WEB interface.
Prior to step 102, the method further comprises: the first network server receives an information packet, wherein the information packet comprises: the method comprises the steps that an intranet IP address of a second terminal (such as a set top box) device (called target device) is obtained, when a first network server receives an information packet, HTTP connection between the first network server and the second terminal (such as the set top box) device (called target device) is established, and the first network server obtains a public network IP address of a local area network where the second terminal (such as the set top box) device (called target device) is located according to the established HTTP connection; and storing the corresponding relation between the public network IP address and the URL address of the second terminal (such as a set-top box) device, wherein the URL address of the second terminal (such as the set-top box) device comprises the intranet IP address of the second terminal (such as the set-top box) device. In another embodiment, the packet is originated by the target device and forwarded through the network device, and when the packet is forwarded through the network device in the line, the network device automatically adds the public network IP address corresponding to the local area network to the packet, so that the subsequent first network server can establish the corresponding relationship between the public network IP address and the internal URL address thereof. In step 103, the first network server may use the public network IP address of the local area network where the first terminal (e.g., a mobile phone) device is located as an index to search for the internal URL address corresponding to the public network IP address. The network device may be a router or a switch, among others.
The URL address of the second terminal (e.g., set-top box) includes an intranet IP address, a file directory address, an access parameter, and the like of the second terminal (e.g., set-top box), and the file directory address is a logical address used for specifying a service on the device and is always determined for a specific task, so that the file directory address does not need to be periodically reported by the second terminal (e.g., set-top box). The first network server generates a URL address by using information such as an intranet IP address, a file directory address, an access parameter and the like reported by a second terminal (such as a set top box) device; in another implementation manner, the second terminal (e.g., a set-top box) device may also directly report the URL address, and the first network server stores the URL address directly reported by the second terminal (e.g., a set-top box) device.
A plurality of target devices share a public network IP address, and for example, a plurality of target devices in a home have a one-to-many correspondence relationship. Or, a cell uses a public network IP address, a plurality of families are provided in the cell, each family has a primary intranet IP address, and each terminal device in each family has a secondary intranet IP address.
In the embodiment of the invention, the first network server receives the query request initiated by the browser of the first terminal (such as a mobile phone) device by using the WEB interface, and sends the internal URL address of the terminal device in the local area network carrying the first terminal (such as the mobile phone) device to the first terminal (such as the mobile phone) device, so that the first terminal (such as the mobile phone) device can establish connection with another terminal device corresponding to the internal URL address by using the browser, and no additional application software needs to be pre-installed on the operating system of the first terminal (such as the mobile phone).
Referring to fig. 2, a second embodiment of the present invention provides a local area network device discovery method for a WEB page, where a terminal device is used as an execution main body, the terminal device may be a mobile phone, a PC, a tablet, and the like, and a description will be given later by taking a mobile phone as an example. The method comprises the following steps:
step 201, the browser of the terminal device (for example, a mobile phone) downloads the WEB page program of the network server according to the address of the network server.
The address of the network server is a URL address, which may be pre-stored on the terminal device or input by the user, and the URL address of the network server includes corresponding IP address information. And the terminal equipment is connected with the URL address and downloads a WEB page program of the network server.
Step 202, the browser of the terminal device (for example, a mobile phone) executes codes in the WEB page program to send a query request.
The WEB page program includes some programs, and the programs can control the browser to send a query request to the WEB server storing the corresponding relationship between the public network IP address and the internal URL address, where the WEB server storing the corresponding relationship between the public network IP address and the internal URL address may be the WEB server providing the WEB page program in step 201 or another WEB server, and the implementation of the present invention is not affected.
Step 203, the browser of the terminal device receives a response message of the query request, where the response message includes: and internal URL addresses of other terminal equipment in the local area network where the terminal equipment is located. The internal URL addresses of other terminal devices in the local area network may include the internal URL address of the set-top box.
One or more internal URL addresses may be included in the response message, where the internal URL addresses include intranet IP addresses (e.g., x.x.x.n 1; x.x.x.n2), directories, and so on.
And step 204, the browser of the terminal equipment initiates a WEB connection request according to the internal URL address so as to establish connection with the terminal equipment corresponding to the internal URL address.
The program included in the WEB page program downloaded in step 201 is used to control the browser to initiate a WEB connection request according to the internal URL address (including an intranet IP address).
And the terminal equipment corresponding to the internal URL address is used as target equipment. In this step, the terminal device may initiate WEB connection requests to the internal URL addresses one by using a browser through AJAX, and attempt to establish a TCP connection. If the response of the target equipment corresponding to the internal URL address (including the intranet IP address) cannot be received within a preset time period, determining that the internal URL address is wrong; and then proceeds to try the next internal URL address (containing the intranet IP address). If the response of the target device corresponding to the internal URL address (including the intranet IP address) is received within the preset time period, the connection is successful. That is, by using AJAX to initiate WEB connection requests one by one to these internal URL addresses using a browser, only other terminal devices belonging to the same minimum subnet as the terminal device (such as a mobile phone) can be connected. If a home corresponds to a public network IP address, other terminal devices in the home can be connected; if a cell corresponds to a public network IP address, each home corresponds to a primary subnet IP address, and each terminal device in each home has a secondary intranet IP address, only other terminal devices belonging to the same home as the terminal device (e.g., a mobile phone) can be connected although a plurality of intranet IP addresses are received in the response message.
Moreover, the program included in the WEB page program downloaded in step 201 is further configured to store the internal URL address (including the intranet IP address) of the target device that receives the response in the cache of the browser, and control the browser to directly connect to the target device according to the internal URL address when a subsequent connection is needed, without repeatedly executing steps 201 to 203.
The terminal device in the embodiment of the invention acquires the internal URL address of other terminal devices (such as a set top box) in the local area network through the browser, and establishes the connection with the terminal device corresponding to the internal URL address by using the browser. The terminal device (such as a mobile phone) uses a WEB browser, can establish connection with the target device by executing the program in the WEB page program, does not need to develop different WEB page programs aiming at different operating systems, is simple to transplant and strong in cross-terminal capability, and does not need to install additional application software on the operating system of the terminal device (such as a mobile phone) in advance.
Referring to fig. 3, an embodiment of the present invention provides a method for reporting an intranet IP address, where the method is executed by a terminal device (e.g., a set top box), and the method specifically includes:
step 301, the terminal device in the local area network environment queries its own intranet IP address.
Step 302, the terminal device sends an information packet to a network server on the internet according to a pre-stored address of the network server, wherein the information packet includes an intranet IP address of the terminal device, and the information packet may further include an identity of the terminal device.
Wherein, the terminal device in this step may send the information packet to the network server on the internet by using a WEB interface.
Step 302 may be periodically sent, that is, the terminal device periodically reports its own intranet IP address.
The information packet is sent from the terminal device and sent to the network server through the network device, and the network device adds the public network IP address to the information packet. The network device can be at least one of a router, a switch and a gateway, the network device can also encrypt the information packet added with the public network IP address and send the encrypted packet to a network server, and the subsequent network server decrypts the encrypted packet and then carries out identity authentication on the terminal device according to the identity of the terminal device, and only receives the information packet with legal identity to prevent network attack and deception.
According to the embodiment of the invention, the terminal device reports the intranet IP address of the terminal device to the network server, so that the network server can establish the corresponding relation between the public network IP address of the local area network and the internal URL address (including the intranet IP address) of the terminal device in the local area network, and another terminal device (such as a mobile phone) can conveniently acquire the internal URL address of the terminal device (such as a set top box) from the network server to establish connection with the terminal device (such as the set top box).
Referring to fig. 4, an embodiment of the present invention provides a local area network device discovery method for a WEB page, where the method specifically includes:
step 401, the set-top box in the local area network environment queries its own intranet IP address.
Step 402, the set-top box sends an information packet to a network server on the internet via the routing device according to a pre-stored address of the network server, wherein the information packet sent by the set-top box includes an intranet IP address of the set-top box and may also include an identity of the set-top box.
The detailed implementation of this step is similar to step 302, and is not described herein again.
Step 403, the network server receives an information packet, where the information packet includes: the intranet IP address of the set-top box, and the information packet can also comprise the identity of the set-top box. The network server verifies whether the set-top box is legal or not according to the identity identification information of the set-top box, and if the set-top box is legal, the corresponding relation between the public network IP address and the internal URL address (including the intranet IP address) of the set-top box is established.
When the network server receives the information packet, the HTTP connection between the network server and the set-top box is established, the network server acquires a public network IP address in a local area network where the set-top box is located according to the established HTTP connection, and a corresponding relation between the public network IP address and an internal URL address of the set-top box is established. In another embodiment, the information packet is originated by the set-top box and forwarded through the network device, and when the information packet is forwarded through the network device, the network device adds its own public network IP address to the information packet, so that the subsequent network server establishes the corresponding relationship between the public network IP address and the internal URL address of the set-top box.
The internal URL address of the set top box comprises an intranet IP address and a file directory address of the set top box, the file directory address can be preset, so that the set top box does not need to report periodically, and the network server generates the internal URL address by using the intranet IP address, the file directory address and other information reported by the set top box; in another implementation, the set-top box may also directly report the internal URL address, and the network server stores the internal URL address directly reported by the set-top box.
Step 404, the browser of the mobile phone downloads the WEB page program from the WEB server according to the address of the WEB server, and the WEB server provides the WEB page program to the mobile phone by using the WEB interface. The WEB page program includes programs, for example, the WEB page program includes: the method comprises the steps of controlling a browser of the mobile phone to send out a query request, and/or controlling the browser of the mobile phone to initiate WEB connection by utilizing an internal URL address (including an intranet IP address, a file directory address, an access parameter and the like) in a local area network, and/or controlling the browser of the mobile phone to store the internal URL address which is successfully connected, and/or controlling the browser of the mobile phone to connect with the stored internal URL address in the subsequent connection.
Step 405, the browser of the mobile phone executes a program for controlling the browser of the mobile phone to send out a query request in the WEB page program to initiate the query request, and the query request is sent to the network server through the routing device.
Step 406, the network server uses the public network IP address as an index according to the corresponding relationship established in step 403, and searches for the internal URL address of other terminal devices in the local area network corresponding to the public network IP address. And the internal URL addresses of other terminal equipment in the local area network corresponding to the public network IP address comprise the internal URL addresses of the set top box.
Step 407, the network server sends a response message to the browser of the mobile phone, where the response message includes an internal URL address corresponding to the public network IP address. Wherein, the internal URL address corresponding to the public network IP address comprises the internal URL address of the set-top box.
And step 408, the browser of the mobile phone initiates a WEB connection request according to the internal URL address to establish the connection with the set top box corresponding to the internal URL address.
For a specific implementation of this step, reference may be made to the following description of step 204, which is not described again.
Step 409, after the connection is successful, the browser of the mobile phone stores the internal URL address of the set-top box in the cache of the browser, so that the browser can be directly connected with the set-top box according to the internal URL address in the subsequent connection.
The specific implementation manner of each step in this embodiment may refer to the corresponding description of the embodiment shown in fig. 1 to fig. 3, and is not described herein again.
In the embodiment of the invention, the network server prestores the corresponding relation between the public network IP address of the local area network and the internal URL address of the terminal equipment (such as a set-top box) in the local area network, and the mobile phone acquires the internal URL address of the terminal equipment (such as the set-top box) in the local area network from the network server through the WEB browser without acquiring the internal URL address from the set-top box in the local area network, so that a UDP (user datagram protocol) packet is not required to be used, and an additional application program is not required to be installed on an operating system of the mobile phone. Moreover, the mobile phone can establish connection with the set-top box by using a WEB browser and executing codes in the unified WEB page program, different WEB page programs do not need to be developed aiming at different operating systems, and the mobile phone is easy to transplant and strong in cross-terminal capability.
