Background
In recent times, wireless network devices with small volume, such as thermal imaging sensors, often do not have wired network ports, so that such devices access a wireless network through an internally integrated wireless module. However, since such devices do not have a display screen like a smart phone, a human-computer interaction interface cannot be provided externally, and further, such devices cannot configure network access related parameters through the screen. Based on this, the wireless network device has to perform network entry parameter configuration by means of other clients or form a local area network only with other terminals that have already accessed the wireless network.
However, at present, the wireless network device configures the network access parameters by using other clients, or the device itself must support the wired network first, so that the other clients log in the device through the wired network and then enter a configuration interface to configure the network access parameters, or the device is required to cooperate with a dedicated APP (Application program) installed in the client to configure the network access parameters based on a mode of transmitting a UDP (User Datagram Protocol) message. Whether the device supports a wired network or the device can receive the UDP message needs to be specially designed aiming at the hardware and software, so that the production and manufacturing cost of the device is inevitably increased.

Based on the above structure, various embodiments of the device network access method are provided.
Referring to fig. 2, fig. 2 is a flowchart illustrating a first embodiment of a device networking method according to the present invention.
While the logical order is shown in the flowchart, in some cases, the steps shown or described may be performed in an order different from that shown or described herein. In this embodiment, the execution main body of the device network access method of the present invention may be a device to be accessed to a wireless network, and the device to be accessed to the network may be a terminal device which has a small volume, does not have a human-computer interaction interface like a mobile phone touch screen, does not have a wired network port, and only inherits a wireless module with a small volume inside to access the wireless network. For example, the device to be networked may be a thermal imaging human body sensor device, an electrical device such as a household appliance, and the like. It should be understood that no limitation is made to the specific type of device to be networked in this embodiment. The following description of the present embodiment is made by directly replacing the above execution main bodies with the devices to be networked.
In this embodiment, the network access method of the device of the present invention includes:
step S10, establishing communication connection between the equipment to be accessed to the network and a preset client, and receiving a resource request message sent by the client based on the communication connection;
it should be noted that, in this embodiment, the preset client is a client that forms a local area network with the to-be-networked device that needs to access the wireless network currently to perform data communication with the to-be-networked device, where the client may specifically be a smart phone, a personal computer, a server, and the like, and is not limited specifically here.
In this embodiment, the device to be networked starts the hotspot function by operating the wireless access point mode, so that the client establishes a communication connection between the device to be networked and the client after accessing based on the hotspot function. Then, the device to be networked may perform data communication with the client based on the communication connection, that is, the device to be networked receives, based on the communication connection, a resource request message sent by the client through the communication connection.
For example, it is assumed that the client is a mobile phone of a user, and a resource request message initiated by the client after accessing a hotspot opened by a device to be networked is specifically an HTTP (hypertext Transfer Protocol) request. As shown in the application flow of fig. 3, when a device to be networked (illustrated as "device") that needs to access a wireless network is started to enter an operation flow of accessing the wireless network, a wireless access point mode of the device to be networked is started to start a hotspot function, so that a user mobile phone can access the device hotspot of the device to be networked and the device to be networked to form a local area network for data communication, and then, the smart phone automatically sends an HTTP request to the device to be networked by starting a browser of the smart phone.
It should be noted that, in this embodiment, after establishing a communication connection with the device to be networked, the client may automatically send, by starting a browser running on the client, an HTTP request in which the URL format is a domain name format or the URL format is an IP format to the device to be networked in the wireless access point mode in which the device to be networked runs.
Step S20, redirecting the resource request message to a virtual network service address of the equipment to be networked, wherein the virtual network service address is preset with a corresponding distribution network page;
in this embodiment, after receiving a resource request message sent by a client through the communication connection, a device to be networked immediately performs a resource redirection operation on the resource request message to redirect the resource request message to a pre-configured virtual network service address of the device to be networked, so that the client further obtains a distribution network page preset by the virtual network service address after obtaining the virtual network service address, so that the client can obtain, based on the distribution network page, wireless network configuration data configured by a user to enable the device to be networked to access a target wireless network, and the client further sends the wireless network configuration data to the device to be networked through the communication connection with the device to be networked.
It should be noted that, in this embodiment, after receiving the resource request message sent by the client through the communication connection, the device to be networked may transmit the distribution network page for configuring the wireless network configuration data to the client for visual output display by using the distribution network page as response data of an access request initiated by the client based on the virtual network service address, so that the client may receive, based on the distribution network page, a network configuration interactive operation performed by a user to obtain the wireless network configuration data.
In some possible embodiments, as shown in the application flow illustrated in fig. 3, the device to be networked may perform a process of feeding back response data to the user handset according to a resource request message, i.e., an HTTP request, sent by the user handset based on the IP redirection and DNS hijacking functions. After receiving the distribution network page fed back by the device to be networked, the client can output and display the distribution network page to the user through the currently running browser, so that the user can perform configuration operation of relevant network access parameters (such as the name, SSID and password of the wireless network) of the target wireless network based on the distribution network page, and further the client can obtain the network access parameters to serve as wireless network configuration data of the target wireless network and further send the wireless network configuration data to the device to be networked.
And step S30, receiving wireless network configuration data submitted by the client through the distribution network page, and accessing a corresponding target wireless network by using the wireless network configuration data.
In this embodiment, the device to be networked feeds back a distribution network page with a preset virtual network service address to the client by redirecting a resource request message initiated by the client, so that after the client obtains wireless network configuration data based on the distribution network page and returns the wireless network configuration data to the device to be networked, the device to be networked further switches from a currently running wireless access point mode to a running WIFI access mode, and thus, the device to be networked adds the resource request message to a target wireless network corresponding to the wireless network configuration data through the wireless network configuration data request.
Exemplarily, as shown in the application flow of fig. 3, after further receiving the wireless network configuration data, i.e., SSID and password, sent by the client, the device to be networked immediately stops operating the wireless access point mode to close the hotspot function, and simultaneously closes the IP redirection and DNS hijacking functions. And then, the device to be accessed to the network further starts a WIFI access mode to open the WiFi function, so that the device to be accessed to the network is added into the target wireless network (namely the target SSID network) according to the SSID and the password request.
In this embodiment, the device to be networked starts the hotspot function by operating the wireless access point mode, so that the client establishes a communication connection between the device to be networked and the client after accessing based on the hotspot function. Then, the device to be networked may perform data communication with the client based on the communication connection, that is, the device to be networked receives, based on the communication connection, a resource request message sent by the client through the communication connection. And then, the device to be networked immediately performs a resource redirection operation on the resource request message to redirect the resource request message to a pre-configured virtual network service address of the device to be networked, so that the client further obtains a distribution network page preset by the virtual network service address after obtaining the virtual network service address, and thus, the client can obtain wireless network configuration data configured by a user to enable the device to be networked to access a target wireless network based on the distribution network page, and further sends the wireless network configuration data to the device to be networked through communication connection with the device to be networked. And finally, the to-be-networked device is further switched from the currently running wireless access point mode to the running WIFI access mode, so that the to-be-networked device is added into a target wireless network corresponding to the wireless network configuration data through the wireless network configuration data request.
Therefore, the device to be accessed to the network firstly operates the wireless access point mode to communicate with the client, so that the client can obtain the wireless network configuration data only by operating the browser to perform communication data interaction with the device to be accessed to the network, and then the device to be accessed to the network can be accessed to the wireless network based on the wireless network configuration data. Therefore, compared with the traditional equipment network access mode of carrying out network access parameter configuration by other clients or only forming a local area network with other terminals, the method does not need to support a wired network by the equipment to be accessed, does not need to install special client software by the client and provide corresponding matching support by the equipment to be accessed, and can realize the network access of the equipment by the client based on a browser only after the connection is established with the client through the hotspot function of the equipment, namely, the equipment can be stably accessed to the wireless network only through the design of the software layer of the equipment under the condition of not increasing the integral production and manufacturing cost of the equipment to be accessed.
In addition, in this embodiment, the device to be networked feeds back an effective IP address to the client for the client to access through relatively mature IP redirection and DNS hijacking so as to further feed back a distribution network page to the client to acquire wireless network configuration data, so that the device is networked in a low-cost manner without considering the influence of performance and environment on function implementation, and the stability of the device in networking is further improved.
In addition, based on the first embodiment of the network access method of the device of the present invention, a second embodiment of the network access method of the device of the present invention is provided. In this embodiment, the main execution body of the device network entry method of the present invention may still be the device to be networked, which is the device to be networked.
In this embodiment, the step S20 of redirecting the resource request message to the virtual network service address of the device to be networked may specifically include:
step S201, sending the virtual network service address of the equipment to be networked to the client according to the resource request message;
in this embodiment, when the device to be networked receives a resource request message initiated by a client, and redirects the resource request message to a pre-configured virtual network service address of the device to be networked, so that the client obtains a configured web page preset by the virtual network service address, the device to be networked feeds back the virtual network service address to the client based on running a DNS hijacking function after receiving the resource request message.
In some possible embodiments, in the step S201, sending the virtual network service address of the device to be networked to the client according to the resource request message may specifically include:
step S2011, determining a URL format of the resource request message;
in this embodiment, after receiving a resource request message, i.e., an HTTP request, sent by a client, a device to be networked parses the HTTP request to determine whether a URL format of the HTTP request is a domain name format or a protocol address format.
It should be noted that, in this embodiment, the domain name format of the URL may specifically be: http:// domain name/resource path, and the protocol address format (i.e., IP format) of the URL may specifically be: http:// IP/resource Path.
Step S2012, if the URL format is a domain name format, sending the virtual network service address of the device to be networked to the client;
it should be noted that, in this embodiment, the preset virtual network card is a virtual network card of a different network segment generated by the device to be networked through an original network card in advance. For example, in this embodiment, the device to be networked may be connected to an operating system of the device to be networked in advance, so that a design and development worker of the device to be networked generates a virtual network card wlan0:1 in a different network segment through an original network card wlan0 of the device to be networked by using the operating system. And the device to be networked configures the IP addresses corresponding to all domain names of the DNS service as the IP address of the virtual network card based on the preset DNS service function provided by the DNS server.
In this embodiment, after the device to be networked resolves and determines the URL format of the HTTP request sent by the client, if the URL is in the domain name format, the device to be networked immediately feeds back the IP address of the preconfigured virtual network card to the client as the currently received intermediate response data of the HTTP request.
For example, as shown in the application scenario of fig. 4, assuming that the device to be networked is an IPC (thermal imaging device), if the URL of an HTTP request sent to the IPC by the above communication connection by a client (PC or user mobile phone) is in the format of HTTP:// domain name/resource path, after receiving the HTTP request sent in the form of a DNS request message, the IPC immediately resolves the domain name by using a DNS service to further send the IP address of a preconfigured virtual network card wlan0:1 as intermediate response data to the client.
Step S2013, if the URL format is a protocol address format, determining whether an Internet protocol address carried by the resource request message is the same as the virtual network service address;
step S2014, if the internet protocol address is different from the virtual network service address, sending the virtual network service address to the client.
In this embodiment, after the device to be networked resolves and determines the URL format of the HTTP request sent by the client, if the URL is in the protocol address format, the device to be networked further immediately determines whether the IP address carried by the HTTP request is the same as the IP address of the virtual network card, so that when it is determined that the IP address carried by the HTTP request is different from the IP address of the virtual network card, the IP address of the virtual network card is immediately fed back to the client as the currently received intermediate response data of the HTTP request.
For example, as shown in the application scenario shown in fig. 4, if the URL of the HTTP request sent by the client (PC or user mobile phone) to the device to be networked IPC through the communication connection is in the format of HTTP:// IP/resource path, after receiving the HTTP request, the IPC immediately processes the currently used HTTP protocol through its own web service to determine whether the IP address carried by the HTTP request is the IP address of the virtual network card wlan0:1, and further, when determining that the IP address of the HTTP request is not the IP address of the virtual network card wlan0:1, the IPC returns the IP address of the virtual network card wlan0:1 as intermediate response data to the client in a manner of returning to the response code of the client 302.
In addition, in some possible embodiments, after the step of "determining whether the internet protocol address carried in the resource request message is the same as the virtual network service address" in the step S2013, the network access method of the device of the present invention may further include:
step S2014 is to send the distribution network page corresponding to the virtual network service address to the client if the internet protocol address is the same as the virtual network service address.
In this embodiment, when the device to be networked further determines that the IP address carried in the HTTP request is the same as the IP address of the virtual network card, the device to be networked may directly feed back the network deployment page as response data to the client.
Exemplarily, as shown in the application scenario of fig. 4, if the URL of the HTTP request sent by the client (PC or user mobile phone) to the device to be networked IPC through the communication connection is in the HTTP:// IP/resource path format, after receiving the HTTP request, the IPC immediately processes the currently used HTTP protocol through its own web service to determine whether the IP address carried by the HTTP request is the IP address of the virtual network card wlan0:1, and further, if the IPC determines that the currently received HTTP request IP address is the IP address of the virtual network card wlan0:1, the IPC feeds back the distribution network page for configuring the relevant network access parameters of the accessed target wireless network as final response data to the client.
Step S202, receiving an access request initiated by the client based on the virtual network service address;
in this embodiment, after receiving the virtual network service address, which is the intermediate response data fed back by the device to be networked, the client further sends an access based on the virtual network service address to the device to be networked, which is the device to be networked, so that the device to be networked feeds back the distribution network page based on the access request.
Exemplarily, after receiving the IP address of the virtual network card fed back by the IPC of the device to be networked, the client further sends an access request (a new HTTP request) carrying the IP address of the virtual network card to the device to be networked based on the currently running browser, so that the IPC feeds back the distribution network page based on the IP address of the virtual network card.
Step S203, responding to the access request to send the distribution network page corresponding to the virtual network service address to the client.
In this embodiment, after receiving an access request initiated by a client based on a virtual network service address, a device to be networked immediately responds to the access request to extract the virtual network service address from the access request, so that the device to be networked directly feeds back the distribution network page as response data to the client when determining that the virtual network service address is the IP address of the virtual network card configured in advance.
In addition, a first embodiment of the network access system of the device of the present invention is proposed based on the first embodiment and/or the second embodiment of the network access method of the device of the present invention.
In this embodiment, the device to be networked system of the present invention includes a device to be networked and a client, where the device to be networked is in communication connection with the client, for example, after the device to be networked starts a hotspot function by operating a wireless access point mode, the client immediately accesses a device hotspot of the device to be networked to establish communication connection with the device to be networked. Wherein:
the equipment to be accessed in the equipment access system is used for: receiving a resource request message sent by the client through the communication connection; redirecting the resource request message to a virtual network service address of the equipment to be networked, wherein the virtual network service address is preset with a corresponding distribution network page; receiving wireless network configuration data submitted by the client through the distribution network page, and accessing a corresponding target wireless network by using the wireless network configuration data;
in addition, the client of the device networking system of the present invention is configured to: sending a resource request message to the equipment to be networked through the communication connection; receiving a virtual network service address fed back by the equipment to be networked in response to the resource request message, and determining wireless network configuration data according to a distribution network page corresponding to the virtual network service address; and sending the wireless network configuration data to the equipment to be networked.
In this embodiment, the device to be networked starts the hotspot function by operating the wireless access point mode, so that the client establishes a communication connection between the device to be networked and the client after accessing based on the hotspot function. Then, the device to be networked may perform data communication with the client based on the communication connection, that is, the device to be networked receives, based on the communication connection, a resource request message sent by the client through the communication connection. And then, the device to be networked immediately performs a resource redirection operation on the resource request message to redirect the resource request message to a pre-configured virtual network service address of the device to be networked, so that the client further obtains a distribution network page preset by the virtual network service address after obtaining the virtual network service address, and thus, the client can obtain wireless network configuration data configured by a user to enable the device to be networked to access a target wireless network based on the distribution network page, and further sends the wireless network configuration data to the device to be networked through communication connection with the device to be networked. And finally, the to-be-networked device is further switched from the currently running wireless access point mode to the running WIFI access mode, so that the to-be-networked device is added into a target wireless network corresponding to the wireless network configuration data through the wireless network configuration data request.
In some possible embodiments, the client of the device networking system of the present invention is configured to: sending a resource request message with a URL format in a domain name format to the equipment to be accessed through the communication connection; or, the client is further configured to send a resource request message in a protocol address format in a URL format to the device to be networked through the communication connection.
In this embodiment, the client may perform data communication based on the communication connection with the device to be networked, so as to send the resource request message in the URL format in the domain name format or the protocol address format to the device to be networked. Namely, the client sends an HTTP request in a URL format of a domain name format or an IP format to the device to be networked based on the communication connection by starting up and running a browser.
For example, in this embodiment, after establishing a communication connection with the IPC of the device to be networked, the client may automatically send the HTTP request with the URL format being the domain name format or the URL format being the IP format to the device to be networked by starting and running the browser of the client in the above-mentioned wireless access point mode of the IPC.
It should be noted that, in this embodiment, the domain name format of the URL may specifically be: http:// domain name/resource path, and the IP format of URL may specifically be: http:// IP/resource Path.
In some possible embodiments, the client of the device networking system of the present invention is configured to: initiating an access request to the equipment to be accessed according to the virtual network service address fed back by the equipment to be accessed; and receiving a distribution network page corresponding to the virtual network service address fed back by the device to be networked responding to the access request.
In this embodiment, after receiving the above-mentioned resource request message, i.e. the HTTP request, sent by the client, the device to be networked immediately resolves and determines whether the URL format of the HTTP request is the domain name format or the IP format. If the URL is in a domain name format, the device to be networked immediately feeds back the IP address of the pre-configured virtual network card to the client as the intermediate response data of the currently received HTTP request. Or after the URL format of the HTTP request sent by the client is determined by analysis, if the URL is in the IP format, the device to be networked immediately further determines whether the IP address carried by the HTTP request is the same as the IP address of the virtual network card, so that when the IP address carried by the HTTP request is determined to be different from the IP address of the virtual network card, the IP address of the virtual network card is immediately fed back to the client as the currently received intermediate response data of the HTTP request.
In this way, the client further sends an access request (a new HTTP request) carrying the IP address of the virtual network card to the device to be networked based on the browser. And then, the equipment to be accessed to the network responds to the access request, so that when the IP address carried in the access request is determined to be the IP address of the virtual network card which is configured in advance, the network distribution page is immediately fed back to the client as response data.
It should be noted that, in this embodiment, the preset virtual network card is a virtual network card of a different network segment generated by the device to be networked through the original network card in advance. For example, in this embodiment, the device to be networked may be connected to an operating system of the device to be networked in advance, so that a design and development worker of the device to be networked generates a virtual network card wlan0:1 in a different network segment through an original network card wlan0 of the device to be networked by using the operating system. And the device to be networked also configures the IP addresses corresponding to all domain names of the DNS service as the IP addresses of the virtual network card based on the preset DNS service function provided by the DNS server.
For example, as shown in the application scenario of fig. 4, assuming that the device to be networked is an IPC (thermal imaging device), if a URL of an HTTP request sent by a client (a PC or a user mobile phone) to the IPC through the above communication connection is in a format of HTTP:// domain name/resource path, after receiving the HTTP request sent in the form of a DNS request message, the IPC immediately resolves the domain name through a DNS service to further send an IP address of a preconfigured virtual network card — wlan0:1 as intermediate response data to the client. Or, if the URL of the HTTP request sent by the client (PC or user mobile phone) to the IPC through the communication connection is in the format of HTTP:// IP/resource path, the IPC immediately processes the currently used HTTP protocol through its own web service after receiving the HTTP request to determine whether the IP address carried by the HTTP request is the IP address of the virtual network card wlan0:1, and further, when determining that the IP address of the HTTP request is not the IP address of the virtual network card wlan0:1, the IPC returns the IP address of the virtual network card wlan0:1 as intermediate response data to the client in a manner of returning to the response code of the client 302. On the contrary, if the IPC determines that the IP address of the currently received HTTP request is the IP address of the virtual network card wlan0:1, the IPC feeds back the distribution network page for configuring the relevant network access parameters of the accessed target wireless network as final response data to the client.
In some feasible embodiments, after receiving the distribution network page fed back by the device to be networked according to the URL format of the HTTP request, the client further obtains, based on the distribution network page, the wireless network configuration parameter of the target wireless network configured by the user and enabling the device to be networked to access, and further sends the wireless network configuration parameter to the device to be networked through the communication connection.
In addition, in this embodiment, the client of the device networking system of the present invention is configured to: and when a user starting instruction is detected, sending the resource request message to the equipment to be networked, visually outputting and displaying the distribution network page, receiving network configuration interactive operation based on the distribution network page, and determining the wireless network configuration data based on the network configuration interactive operation.
In this embodiment, in a scene of actual operation of a user, the user only controls the client to initiate a user start instruction for controlling the browser of the client to start and operate, so that the client can respond to the user start instruction to perform a series of data interaction operations with the device to be networked to receive the distribution network page fed back by the device to be networked. Then, the client can visually output and display the distribution network page to the user through the currently running browser, so that the user can perform configuration operation of relevant network access parameters (such as the name, SSID and password of the wireless network) of the target wireless network based on the distribution network page, and further, the client can obtain the network access parameters to serve as wireless network configuration data of the target wireless network and further send the wireless network configuration data to the equipment to be networked. And after receiving the wireless network configuration data, the device to be networked can be switched from the currently running wireless access point mode to the running WIFI access mode, so that the device to be networked requests to be added into a target wireless network corresponding to the wireless network configuration parameters through the wireless network configuration parameters.
In this embodiment, the device to be networked operates the wireless access point mode first to communicate with the client, so that the client can obtain the wireless network configuration data by only operating the browser to perform communication data interaction with the device to be networked, and then the device to be networked can access the wireless network based on the wireless network configuration data. Therefore, compared with the traditional equipment network access mode of carrying out network access parameter configuration by other clients or only forming a local area network with other terminals, the method does not need to support a wired network by the equipment to be accessed, does not need to install special client software by the client and provide corresponding matching support by the equipment to be accessed, and can realize the network access of the equipment by the client based on a browser only after the connection is established with the client through the hotspot function of the equipment, namely, the equipment can be stably accessed to the wireless network only through the design of the software layer of the equipment under the condition of not increasing the integral production and manufacturing cost of the equipment to be accessed.
In addition, for the actual operation that the user specifically controls the client to control the device to be networked to access the wireless network, the user only needs to trigger a starting instruction based on the client, and then the client can automatically perform a series of data interaction with the device to be networked and directly output and display a distribution network page to the user, so that the user can start the configuration of the related data of the wireless network. Therefore, the technical scheme of the invention further simplifies the operation of the user on the equipment access to the wireless network, and greatly improves the use experience of the user. The starting instruction in this embodiment includes, but is not limited to: the method comprises the steps of opening a client application program and creating a new window in the client application program, and is characterized in that a user does not need to input information of access targets such as specific network addresses or IP addresses, and the resource request message is automatically sent to the equipment to be networked by operating some original operations of the client, so that the network access configuration of the equipment to be networked can be opened noninductively, and the user experience is improved.
In addition, the embodiment of the invention also provides a device for accessing the network.
