However, those of ordinary skill in the art will understand that in various embodiments of the present invention, numerous technical details have been set forth in order to provide a better understanding of the present application. However, the technical solutions claimed in the present application can be implemented without these technical details and with various changes and modifications based on the following embodiments. The following embodiments are divided for convenience of description, and should not be construed as limiting the specific implementation of the present invention, and the embodiments can be mutually combined and referred to without contradiction.
One embodiment of the invention relates to a server connection method which is applied to Internet of things equipment. According to the server connection method, different server addresses are not required to be preset for the Internet of things equipment in different areas when the Internet of things equipment leaves a factory, and a unified domain name address is preset for all the Internet of things equipment, and is corresponding to the connection address of each area server, so that the Internet of things equipment is connected to the area server of the area to which the Internet of things equipment belongs, the Internet of things equipment in different areas can be managed conveniently, management cost of the Internet of things equipment in links of production, logistics, sales and the like is reduced, unified production and global delivery of the Internet of things equipment are achieved.
The implementation details of the server connection method of the present embodiment are specifically described below, and the following description is provided only for convenience of understanding, and is not necessary to implement the present embodiment. The specific flow of the server connection method in this embodiment is shown in fig. 1, and includes:
step 101, sending a request message to a domain name server; the request message is used for requesting the connection address of the area server corresponding to the domain name.
Specifically, because the correspondence between the domain name and the area server is stored in the domain name server, when the internet of things device needs to be connected, a request message carrying the domain name is sent to the domain name server first, so as to request the connection address of the area server corresponding to the carried domain name to the domain name server.
In one example, the correspondence between the domain name and the area server is one-to-many, specifically, a unified domain name is applied for all areas in advance, that is, when the internet of things equipment leaves the factory, a unified domain name address is preset for the internet of things equipment in all areas, so that the internet of things equipment can send a request message for requesting the connection address of the area server corresponding to the domain name server (Domain Name Server, DNS) through the domain name address. By presetting unified domain names for all the area internet of things equipment and enabling the domain names to correspond to the connection addresses of all the area servers, different connection addresses do not need to be preset for the area internet of things equipment in different areas when the area internet of things equipment leaves the factory.
Step 102, receiving a connection address of a first area server corresponding to the domain name returned by the domain name server, and initiating connection to the first area server according to the connection address, so that the first area server can judge whether the area server of the area where the internet of things equipment belongs is the first area server.
Specifically, after a request message for requesting a connection address of a region server corresponding to a domain name from a domain name server is received by the internet of things device, the connection address of a first region server corresponding to a carried domain name returned by the domain name server is received, and then connection is initiated to the first region server according to the received connection address of the first region server.
In a specific implementation, if the internet of things device initiates connection to the first area server, the first area server allows the internet of things device to be accessed, namely, the connection with the first area server is successful, the first area server is the area server of the area where the internet of things device belongs, and the internet of things device is kept online and can operate normally; if the first area server refuses the access of the internet of things device, that is, the connection between the internet of things device and the first area server fails, the step 103 is entered to indicate that the first area server is not the area server of the area where the internet of things device belongs.
Step 103, if the connection address of the second area server sent by the first area server is received, connection is initiated to the second area server according to the connection address of the second area server.
Specifically, the first area server refuses the access of the internet of things device, namely, under the condition that the connection between the internet of things device and the first area server fails, as each area server stores the connection address of the area server of the area where each internet of things device belongs, the internet of things device receives the connection address of the second area server of the area where the internet of things device belongs, which is sent by the first area server, and initiates connection to the second area server according to the connection address of the second area server. Because the second area server is the area server of the area where the Internet of things equipment belongs, the second area server allows the Internet of things equipment to be accessed, namely the Internet of things equipment is successfully connected with the second area server, so that the Internet of things equipment is kept online, and subsequent work is performed.
It can be understood that the connection address in this embodiment is an IP address; the correspondence between the domain name and the area server includes: the corresponding relation between the domain name and the IP addresses of the regional servers initiates connection to the corresponding regional server through the IP address of the regional server.
In this embodiment, a request message for requesting a connection address of an area server corresponding to a domain name is sent to the domain name server, and because the request message carries the domain name and the corresponding relation of the area server is stored in the domain name server, after receiving the connection address of a first area server corresponding to the domain name returned by the domain name server, connection can be initiated to the first area server according to the connection address, so that the first area server determines whether the area server of the area to which the internet of things device belongs is the first area server, in addition, since the connection addresses of the area servers of the areas to which the internet of things device belongs are stored in the area servers, if the area server of the area to which the internet of things device belongs is not the first area server, the first area server can send the connection address of a second area server of the area to which the internet of things device belongs to the internet of things device, and then the internet of things device can successfully connect the second area server according to the connection address of the second area server, and then the internet of things device and the internet of things device can successfully connect with the second area server. Therefore, when the Internet of things equipment leaves the factory, different server addresses are not required to be set for the Internet of things equipment in different areas, only one unified domain name address is required, and the domain name address corresponds to the connection address of each area server, so that the Internet of things equipment is connected to the area server of the area to which the Internet of things equipment belongs, the Internet of things equipment in different areas can be managed conveniently, and management cost of the Internet of things equipment in links of production, logistics, sales and the like is reduced.
Another embodiment of the present invention relates to a server connection method, which is applied to an internet of things device, and a specific flow of the server connection method of the present embodiment is shown in fig. 2, and includes:
step 201, sending a request message to a domain name server; the request message is used for requesting the connection address of the area server corresponding to the domain name.
Step 202, receiving a connection address of a first area server corresponding to the domain name returned by the domain name server, and initiating connection to the first area server according to the connection address, so that the first area server can judge whether the area server of the area where the internet of things equipment belongs is the first area server.
In step 203, if the connection address of the second area server sent by the first area server is received, connection is initiated to the second area server according to the connection address of the second area server.
Steps 201 to 203 are substantially the same as step 101 and step 103, and will not be described here again.
And step 204, disconnecting the connection with the second area server and initiating connection to the third area server if the connection address of the third area server sent by the second area server is received.
Specifically, after the connection between the internet of things device and the second area server is initiated and succeeded, at a certain moment later, as the area to which the internet of things device belongs changes, or the triggering of some events, for example, when the operation and maintenance operation is implemented, the internet of things device needs to be connected to another area server to operate, the second area server can acquire the information of the area to which the internet of things device belongs again, and according to the area to which the internet of things device belongs, the connection address of the third area server is sent to the internet of things device, namely, the third area server is the area server of the area to which the internet of things device belongs after the area to which the internet of things device belongs is changed, then the internet of things device is disconnected with the second area server, and connection is initiated to the third area server.
It can be understood that the connection address of the third area server includes an IP address of the third area server, so that when the area to which the internet of things device belongs changes at a certain moment, the internet of things device is connected with the changed area server.
In this embodiment, after the connection between the internet of things device and the area server of the area to which the internet of things device belongs is successful, if the area to which the internet of things device belongs changes at a certain moment, the area server may also send the connection address of the area server of the area to which the internet of things device belongs after the area to which the internet of things device belongs changes to the internet of things device, so that the internet of things device is connected with the area server after the change.

step 301, receiving a request message sent by an internet of things device and used for requesting a connection address of a region server corresponding to a domain name; wherein the request message carries a domain name.
Step 302, obtaining a connection address of a first area server corresponding to a carried domain name according to a pre-stored correspondence between the domain name and the area server;
the corresponding relation between the domain name and the area server is one-to-many, and the first area server is any area server corresponding to the carried domain name.
Step 303, returning the connection address of the first area server to the internet of things device, so that the internet of things device initiates connection to the first area server.
It can be understood that, in this embodiment, the connection address is an IP address, and the correspondence between the domain name and the area server includes: correspondence between a domain name and each of the IP addresses of the plurality of regional servers.
In this embodiment, a request message sent by an internet of things device and used for requesting an IP address of any area server is received, according to a pre-stored correspondence between a domain name and an area server, a connection address of a first area server corresponding to the carried domain name is obtained, and then the connection address of the first area server is returned to the internet of things device, so that the internet of things device initiates connection to the first area server, the area to which the internet of things device belongs is prevented from being distinguished, and the connection address of any area server can be returned to the internet of things device.
Another embodiment of the present invention relates to a server connection method, applied to an area server, where a specific flow of the server connection method in this embodiment is shown in fig. 4, and includes:
step 401, if a connection request initiated by the internet of things device is received, determining whether an area server of an area to which the internet of things device belongs is an area server.
Specifically, since the information of the area to which each piece of the internet of things equipment belongs, for example, the information of the area server of the area to which the piece of the internet of things equipment belongs, the connection address of the area server, and the like, are stored in each area server in advance, if the area server receives the connection request initiated by the piece of the internet of things equipment, it is first determined whether the area server of the area to which the piece of the internet of things equipment belongs is the area server to which the piece of the internet of things equipment requests connection.
