3. Send messages

With access_token, you can use the message push interface of Enterprise WeChat to send messages. Enterprise WeChat provides a variety of message types, including text, pictures, voice, videos, files, etc.

4. Security considerations

When developing the PHP interface for the enterprise WeChat message push function, security issues need to be considered. It is necessary to ensure that only legitimate requests can call the interface and prevent the interface from being abused.

You can use signatures to verify the legitimacy of the request. The signature algorithm can use the SDK provided by Enterprise WeChat to calculate the signature based on the parameters and secret in the request. Then the signature and the request are sent to the interface, and the interface verifies the correctness of the signature. This ensures that the request comes from a legitimate source.

Summary

Through the above steps, you can develop a PHP interface for the enterprise WeChat message push function. Using the interface of Enterprise WeChat can flexibly realize various message push needs. During the development process, you need to pay attention to security issues and protect the interface from abuse and attacks. At the same time, the application of Enterprise WeChat can be further improved by combining other functions and interfaces according to actual needs.
