The WeChat official account development token is a credential used to verify the identity and authority of the developer. In the development of WeChat public accounts, developers need to obtain tokens to make interface calls to realize interaction with WeChat servers.
The WeChat official account development token is a credential used to verify the identity and authority of the developer. Through a series of verification steps, the developer can obtain the token and make interface calls.
New Mileage Technology, a professional WeChat official account development company, will introduce to you, what is the WeChat official account development token?
Token is a string, which is generated by the WeChat server and returned to the developer. The developer uses this token for authentication in subsequent interface calls. The process of generating and obtaining Token is as follows:
1. The developer creates an official account on the WeChat official platform and completes relevant configurations, including filling in server configurations, setting interface addresses, etc.
2. In the server configuration, the developer needs to set a Token to verify the identity of the server. This Token can be set by the developer. It is recommended to choose a complex and difficult to guess string.
3. After the developer completes the server configuration, the WeChat server will send a GET request to the developer’s server, which contains four parameters: signature, timestamp, nonce, and echostr.
4. After receiving the request, the developer’s server needs to perform verification according to the verification rules provided by the WeChat public platform. First, sort the three parameters of Token, timestamp and nonce set by yourself in lexicographical order, and then concatenate the three parameters into a string for sha1 encryption.
5. Compare the encrypted character string with the signature sent by the WeChat server. If they are consistent, the verification is passed and the developer’s server can respond normally.
6. After the verification is passed, the developer’s server needs to return the echostr sent by the WeChat server as it is. After returning, the WeChat server will confirm that the developer’s server is valid, and then the interface can be used normally.
Through the above steps, the developer successfully obtained the token and verified the identity and authority of the server. In subsequent interface calls, the developer needs to pass the token as a parameter to the WeChat server to ensure the legitimacy of the interface call.
It should be noted that the token has a certain timeliness, and the WeChat server will refresh the token periodically. Therefore, developers need to update the token in time when the interface is called to ensure the normal use of the interface.
