I have recently done WeChat payment development,This is my first contact with .I have taken many detours,I have also encountered many problems.In order to be like me Newcomers no longer encounter similar problems,I write down my development steps and problems,for reference.

The development time is 2016/8/2,so the version of WeChat payment also corresponds to the version at this time.

一.Preparation:

3.After configuration, go to the WeChat public platform,There is a WeChat payment function as shown below.Set the payment directory and test directory in the development configuration.This is mainly for configuration testing Directory , You can ignore the payment directory ( my domain name is www.test.com), and then add your WeChat ID to the test whitelist .

4.Go to the WeChat public platform again>>>Development>>>Interface permissions>>>The first item of web service `web account`,change its value to your own domain name(just the domain name).As shown in the picture:

II.democode modification(only for the current version):

1. Modify the fileWxPay.Api.php

   将curl_setopt($ch,CURLOPT_SSL_VERIFYPEER,TRUE);

       curl_setopt($ch,CURLOPT_SSL_VERIFYHOST,2);//严格校验
   改为:

       curl_setopt($ch,CURLOPT_SSL_VERIFYPEER,FALSE);

       curl_setopt($ch,CURLOPT_SSL_VERIFYHOST,FALSE);//严格校验2

三.开始开发,按大概流程讲述:

1.Pay:First click Pay, will go to the jsapi.php file to , get openid, I don’t care about this step ,There’s nothing wrong either;

Then it’s a unified order , He will set a lot of parameters , as shown in the picture :

Set the setNotify_url inside to the location of your notify.php file.

The two parameters setOut_trade_no and setTotal_fee can be filled in at will (Other parameters can be defaulted).After the payment is successful, the WeChat server will The value of each parameter is returned to you.I directly put the product order number into setOut_trade_no and passed it over.In this step,the problem I encountered is , the string parameter passed by get always cannot be placed in setOut_trade_no,Finally, I found that the order string passed was inexplicably added with single quotes.So I After receiving the string, first use the trim function to process , and then put it in .

   此时点击支付,应该可以去支付了.(支付的结果在商户平台中查看)
