How does WeChat public platform apply for message interface?

The message interface of WeChat public platform provides a new message processing method for developers.

Second, the application message interface

Click Apply, truthfully fill in the name, mobile phone number and email address of the person in charge, and fill in the website address and token of the website. The token can be filled by the developer at will to generate the signature.

Three. Website visit

After the public platform user submits the information, we will request the filled Url in the form of GET request, which has four parameters:

* Signature-WeChat encrypted signature

* Timestamp-Timestamp

* Current random number

* echostr- random string

Developers check the legality of URL access by checking the signature. If the GET request returns the echostr parameter content as it is, the access will take effect, otherwise the access will fail. Verifying the signature will encrypt the process by combining token parameters, timestamp parameters and nonce parameters filled by the developer:

* Token, timestamp and nonce are sorted in dictionary order.

* Splicing three parameter strings into one string for SHA 1 encryption.

* The encrypted string obtained by the developer can be compared with the signature, indicating that the request originated from WeChat.

Fourth, message push.

When an ordinary WeChat user sends a message to a public account, the public platform will post the message to the filled Url (SMS and geographic location messages are now supported). Its structure is as follows:
