This article mainly introduces the example analysis of Wechat interface development, which has a certain reference value, interested friends can refer to, I hope you can learn a lot after reading this article, let the editor take you to know it.

Signature verification is required during the creation process, as described below:

After the user of the public platform submits the information, we will request it to the entered Url in the form of GET request, with four parameters:

* signature-Wechat encryption signature

* timestamp-timestamp

* nonce-Random number

* echostr-Random string

Developers verify the validity of URL access by verifying signature. If the content of the echostr parameter is returned as is for this GET request, the access takes effect, otherwise the connection fails. The verification signature will be combined with the token parameters, timestamp parameters and nonce parameters entered by the developer, and the encryption process:

* sort the three parameters token, timestamp and nonce in lexicographic order

* concatenate three parameter strings into one string for SHA1 encryption

* the encrypted string obtained by the developer can be compared with signature to indicate that the request originated from Wechat.

Code:

However, Wechat does not transmit data through json:

So use simplexml_load_string to load XML data as objects, and find that the POST method is not urlencode, so set HTTP_RAW_POST_DATA, and then you can read the data.
