WeChat third-party platform regularly receives component_verify_ticket, and third-party platform ticket push_PHP tutorial

WeChat third-party platform regularly receives component_verify_ticket, and third-party platform ticket push

Background:

Get the third-party platform token (component_access_token) and add the component_verify_ticket parameter. component_verify_ticket is continuously pushed by the public platform to the third-party platform every 10 minutes (the push will not start until the third-party platform has approved the creation of the public account).

Target:

Receive component_verify_ticket

pushed by WeChat server

Document description: (See WeChat Open Platform Documentation)

Push component_verify_ticket protocol

After the public account is created and approved by the third-party platform, the WeChat server will regularly push component_verify_ticket to its "Authorization event receiving URL" every 10 minutes. The third-party platform also needs to decrypt the ticket push after receiving it (see [Message Encryption and Decryption Access Guidelines] for details), and must directly return the string success after receiving it.

So look for “Authorization Event Receiving URL” in the Open Platform Management Center, as shown below.

Intercept the POST request address of component_verify_ticket pushed by WeChat:

http://[Authorization event receiving URL]?encrypt_type=aes
🎜>        &signature=xxxxxxx

Request content format:

                                                                                                                       xml>

After knowing the format of WeChat push xml, the next thing to do is to decrypt the xml, so continue reading the document (see WeChat Open Platform Message Encryption and Decryption Guide)

Regarding decryption, the WeChat public platform provides sample codes in 5 languages: c, php, java, python, c# (click to download)

Here is a sample code based on the PHP version to implement PHP receiving component_verify_ticket (based on CI framework)
