The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The embodiment of the application provides an access method, which is applied to an internet of things gateway, and as shown in fig. 1, the method can include the following steps:
s11, sending a DHCP request message to a Dynamic Host Configuration Protocol (DHCP) server in the internet of things where the DHCP request message is located.
And S12, receiving a DHCP response message sent by the DHCP server, and acquiring and storing the configuration information of the Internet of things platform to be accessed from the DHCP response message.
In this step, the configuration information includes an IP address and port information of the internet of things platform to be accessed.
Specifically, when the gateway of the internet of things acquires the configuration information of the platform of the internet of things to be accessed from the DHCP response message, the gateway of the internet of things may acquire the configuration information of the platform of the internet of things to be accessed from an option field specified in the DHCP response message.
For example, the specified Option field may be an Option174 field or the like, and the Option174 field may specifically include a Data Length field, an Option Type field, a Server Address field, and a Port value field.
Wherein, the Data Length field represents the byte Length of the Option content; the Option Type field represents the number of ports; the Server Address field represents the IP Address of the platform of the Internet of things; the Port value field represents a Port of the platform of the internet of things, the length of the Port value field is determined by the Option Type field, and the ports can be sequentially arranged.
It should be noted that, in the embodiment of the present application, configuration information of an internet of things platform to be accessed is not separately and manually configured on each internet of things gateway in the internet of things, but configuration information of the internet of things platform to be accessed by the internet of things gateways is configured on the DHCP server in batch in advance, so that after receiving a DHCP request message sent by any one internet of things gateway, the DHCP server carries the configuration information of the internet of things platform to be accessed by the internet of things gateway in an option174 field in a DHCP response message and sends the configuration information to the internet of things gateway.
The subsequent Internet of things gateway can acquire the relevant configuration information of the Internet of things platform needing to be accessed by analyzing the field contents and finally accesses the corresponding Internet of things platform, the configuration workload is greatly reduced by the access mode, the labor cost is reduced, and meanwhile, the manager can conveniently manage all the Internet of things gateways in batches, particularly, the Internet of things gateways without serial ports are conveniently managed.
And S13, accessing to the Internet of things platform to be accessed according to the configuration information and the IP address allocated to the platform in the DHCP response message.
In this step, the specific access procedure is prior art and will not be described in detail herein.
Further, in this embodiment of the present application, when an IP address used by the gateway of the internet of things is about to expire, the following operations may be performed:
sending a DHCP address renewal request message to a DHCP server;
receiving a DHCP address continuation response message sent by a DHCP server;
if the IP address allocated to the DHCP address continuation response message carried in the DHCP address continuation response message is inconsistent with the IP address currently used, acquiring and storing configuration information carried in the DHCP address continuation response message;
and re-accessing to the platform of the Internet of things corresponding to the configuration information carried in the DHCP address continuation response message according to the configuration information carried in the DHCP address continuation response message and the IP address allocated to the DHCP address continuation response message.
It should be noted that, if the administrator needs to replace the IP address and the internet of things platform by the internet of things gateway, the relevant configuration information may be changed on the DHCP server side, and when the subsequent internet of things gateway initiates the DHCP address renewal process, the new IP address and the configuration information of the internet of things platform to be newly accessed are carried in the DHCP address renewal response message and sent to the internet of things gateway, so that the internet of things gateway uses the new IP address to access the new internet of things platform.
If the manager does not need to replace the IP address and the Internet of things platform by the Internet of things gateway, when the Internet of things gateway initiates a DHCP address continuation process, the DHCP server responds to the Internet of things gateway according to the existing mode.
The above access method is described in detail with reference to specific embodiments.
As shown in fig. 2, the internet of things gateway 21, the internet of things gateway 22, and the internet of things gateway 23 in the internet of things are all responsible for receiving and sending messages from the terminal, assuming that these internet of things gateways are all Long range gateways, taking the internet of things gateway 21 as an example, assuming that the internet of things gateway 21 needs to access to port 1 (i.e., pull port, port number is 1680) and port 2 (i.e., push port, port number is 1682) of the internet of things platform 24 with an IP address of 192.168.1.1, and the specific access flow is as follows:
the internet of things gateway 21 sends a DHCP request message to the DHCP server 25.
After receiving the DHCP request message, the DHCP server 25 creates a corresponding DHCP response message and sends the DHCP response message to the internet of things gateway 21.
After receiving the DHCP response packet, the internet of things gateway 21 parses the IP address allocated to itself, and continues to obtain the following configuration information from the DHCP response packet:
AE 09 02 C0 A8 01 01 06 90 06 92
wherein "AE" represents the option174 field;
"09" indicates that the remaining 9 bytes are the content of the option174 field;
"02" indicates that the number of ports is 2;
"C0 a 80101" indicates that the IP address of the internet of things platform is 192.168.1.1;
"0690" indicates that port 1 is 1680, i.e., hexadecimal (0690) is converted to decimal (1680);
"0692" indicates that port 1 is 1680, i.e., hexadecimal (0692) is converted to decimal (1682).
