For example, when the return value of the transmission interface is less than zero, it indicates that the transmission has failed, and when the return value of the transmission interface is greater than or equal to zero, it indicates that the transmission has succeeded.
The transmission failure is indicated in the case where the return value of the reception interface satisfies a specific condition, and the transmission success is indicated in the case where the return value of the reception interface satisfies another specific condition. For example, in the case where the return value of the receiving interface is less than zero, it indicates that the reception has failed, and in the case where the return value of the receiving interface is greater than or equal to zero, it indicates that the reception has succeeded.
The method for sending the request message with the set format to the router again by the internet of things device comprises the following steps: and after the time is set, sending a request message to the router. Alternatively, the set time is 0.5min to 3min, for example, the set time is 0.5min, 1min, 1.5min, 2min or 3min.

Optionally, sending a request packet with a set format to the router includes: and sending the browser type, the recognizable content type, the host name and the preset request character string which are arranged according to the set format to the router.
The set format conforms to the application layer protocol of the network communication model between the internet of things equipment and the router. For example, application layer protocols include: hypertext Transfer Protocol over secure Layer (https) or hypertext Transfer Protocol (http). Similarly, the preset request character string also conforms to the application layer protocol of the network communication model between the internet of things device and the router.
Therefore, after the TCP connection is established between the Internet of things equipment and the router, data can be transmitted between the Internet of things equipment and the router according to the set format.
In some specific applications, the application layer protocol is http, and the request message with the set format sent to the router by the internet of things device is an http request message.

The hostname refers to a hostname and port number, a virtual hostname and port number, a domain name and port number, or an IP address and port number of the router.
In some specific applications, the request message is: GET/HTTP/1.1\ r \ nUser-Agent, browser type \ r \ nACCept, recognizable content type \ r \ nHost, host name \ r \ nConnection, close \ r \ n \ r \ n. Wherein, GET/HTTP/1.1, and \ r \ nConnection, close \ r \ n \ r \ n are preset request character strings. For example, the specific content of the request message is "GET/HTTP/1.1\ r \ nUser-Agent: HAIER \ r \ nACCept:/r \ nHost: none \ r \ nConnection: close \ r \ n'.
Optionally, before the router sends the request packet with the set format, the method for acquiring router information further includes: and generating a request message with a set format. For example, the browser type, the identifiable content type, the host name and the preset request character string are obtained, and the browser type, the identifiable content type, the host name and the preset request character string are arranged according to the set format to obtain the request message conforming to the set format.
Referring to fig. 3, analyzing the response packet to obtain the router information includes:
s301, inquiring the first character string and the second character string in the response message.
The first character string and the second character string are two corresponding character strings, and the second character string usually appear in pairs. One of the first character string and the second character string is a start identifier, and the other is an end identifier.
The first character string and the second character string are used for marking the character string between the first character string and the second character string, and generally have the function of explanation.
In some practical applications, the first string is < title >, and the second string is </title >, and the first string is a start identifier and the second string is an end identifier. The first character string and the second character string explain the role of the character strings between the two: titles that can be displayed.

s401, judging whether the router information is collected.
And the Internet of things equipment directly inquires whether the router information of the currently connected router is collected. For example, a collection status bit is set, and after the router information of the currently connected router is collected, the collection status bit is set to be "1", which indicates that the router information of the currently connected router has been read. After the communication connection based on TCP/IP is established between the Internet of things equipment and the router, reading the acquisition state bit, and acquiring the router information if the acquisition state bit is '1'; if the collection status bit is "0", no router information is collected.
Or reading the identifier of the currently connected router, and inquiring the identifier in the identifier list to obtain an inquiry result. If the identifier is found in the identifier list, the router information is collected; if the identifier is not found in the identifier list, no router information is collected. The identifier list stores identifiers of routers which have collected router information, and the identifiers of the routers comprise BSSIDs or MAC addresses.

The reception failure is indicated in the case where the return value of the reception interface satisfies a specific condition, and the reception success is indicated in the case where the return value of the reception interface satisfies another specific condition. For example, in the case where the return value of the receiving interface is less than zero, it indicates that the reception has failed; in case the return value of the receiving interface is greater than or equal to zero, a successful reception is indicated.
The method for retransmitting the router information to the server by the internet of things device comprises the following steps: and after the time is set, the Internet of things equipment sends router information to the server. Alternatively, the set time is 0.5min to 3min, for example, the set time is 0.5min, 1min, 1.5min, 2min or 3min.
The internet of things equipment continuously sends the router information to the server until the return value of the sending interface is larger than or equal to zero after the router information is sent for a certain time, and the return value of the receiving interface is larger than or equal to zero to indicate that the server successfully receives the router information, and the internet of things equipment stops sending the router information to the server.
