Referring to fig. 1, fig. 1 is a schematic diagram of a visual agricultural data platform system according to an embodiment of the present invention, where the communication method of the internet of things includes the following steps:
step S100, the user side sends a handshake instruction to the authentication and authorization server to indicate the identity type of the user side; the user terminal also refers to a user terminal device.
Step S200, after the authentication authorization server receives the handshake instruction, it is determined whether the user is a registered user
Step S300, if yes, returning to the address of the jump server; that is, in the communication method, a separate authentication and authorization server is provided to process requests of login, registration and the like of a user, so that the load of the server is balanced.
And step S400, after receiving the returned jump server address, the user side establishes communication connection with the service server according to the jump server address, wherein the jump server address is the address of the service server. That is, the user who has authorized the login is authenticated by the authentication and authorization server, and then jumps to the service server of the corresponding address according to the returned server address.
Wherein, in the step of judging whether the user is a registered user, if the user is a non-registered user, the following steps are executed,
