PHP version WeChat js-sdk payment Interface Class Usage example

This article mainly introduces the PHP version of the JS-SDK payment interface class usage, combined with instance form analysis of the PHP version of the JS-SDK payment interface class definition and related use skills, the need for friends can refer to the next

This payment class is based on the Official document modification! The main implementation of the generated JS API, native package signature packages and native response XML format data. The comments are labeled with the intent of each method. Because the package signature, slightly complex, this should spend more time to correspond to see and log out of the file to one by one contrast! Of course, as long as you use the tutorial class, set the corresponding parameters can be correctly generated package parameters, etc.

JS API generated Packages signature Package parameters:

{  "appId": "Wx9998ff5f4dede5b7",  "package": "Bank_type=wx&body=test&fee_type=1&input_charset =utf-8&notify_url=http%3a%2f%2fwww.demo.com%2fnotify&out_trade_no=vf5qsswtu0hc2loh&partner= wx9998ff5f4dede5b7&spbill_create_ip=127.0.0.1&timestamp=1409295711&total_fee=1&sign= Fee0167bd0d89a88bf6850590ea889b6 ",  " TimeStamp ": 1409295711,  " noncestr ":" Vf5qsswtu0hc2loh ",  " paysign ":" f816264c750923863c370a1739640244b0c2d39c ","  Signtype ":" SHA1 "}

XML format for Native response:

<xml>  <appid><![ cdata[wx9998ff5f4dede5b7]]></appid>  <Package>    <![ cdata[bank_type=wx&body=test&fee_type=1&input_charset=utf-8&notify_url=http%3a%2f% 2fwww.demo.com%2fnotify&out_trade_no=gdl3what4saldead&partner=wx9998ff5f4dede5b7&spbill_create_ip= 127.0.0.1&timestamp=1409296124&total_fee=1&sign=bf949b85570644b939b369fd44b0c4a9]]>  </ package>  <TimeStamp>1409296124</TimeStamp>  <noncestr><![ cdata[gdl3what4saldead]]></noncestr>  <RetCode>0</RetCode>  <reterrmsg><![ Cdata[ok]]></reterrmsg>  <appsignature><![ Cdata[ca4a2467b817a62c38a9801fcf451f51692027bf]]></appsignature>  <signmethod><![ Cdata[sha1]]></signmethod></xml>

URL links for native:

weixin://wxpay/bizpayurl?appid=wx9998ff5f4dede5b7&noncestr=vy7cva6mtvrc1bvq&productid=9701&sign= 43508b65b50e1d7e1089be66d55a709469155d73&timestamp=1409296323

Either way, we have to use SetParams to set the necessary initialization parameters and commodity prices and status, etc.!
