php微信支付（仅Jsapi支付）详细步骤.----仅适合第一次做微信开发的程序员

本人最近做了微信支付开发,是第一次接触.其中走了很多弯路,遇到的问题也很多.为了让和我一样的新人不再遇到类似的问题,我把我的开发步骤和问题写出来,以供参考.

开发时间是2016/8/2,所以微信支付的版本也是对应此时的版本.

一.前期准备：

首先你们公司开通微信支付功能后，会收到一份邮件，里面有账户相关信息，一般有：微信支付商户号，商户平台登录帐号，商户平台登录密码，申请对应的公众号，公众号APPID。

1.下载demo：用上面信息登陆“微信商户平台”，>>>（右上角开发文档）>>>公众号支付>>>sdk下载>>>选php

2.下载证书：账户中心>>>api安全

3.配置好后去微信公众平台,里面有微信支付功能如下图.在开发配置中设置支付目录和测试目录.这里主要是配置测试目录,支付目录可以先不管(我的域名是www.test.com),然后将自己的微信号加入测试白名单.

 

 

    4.再去微信公众平台>>>开发>>>接口权限>>>网页服务的第一项`网页账号`,修改它的值为你自己的域名(仅仅是域名).如图:

 

 

 

二.demo代码修改(仅仅针对当前的版本):

     1.  修改文件WxPay.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

       $baseUrl = urlencode('http://'.$_SERVER['HTTP_HOST'].$_SERVER['PHP_SELF'].$_SERVER['QUERY_STRING']);

   或者在写链接时写两个??传参,例如:http://www.test.com/demo/example/jsapi.php??id=xxx&...

 

<span style="font-size: 16px;"><span lang="EN-US"> 3.</span>删去<span style="font-family: Calibri, sans-serif;" lang="EN-US">wxpay.notify.php</span>中的<span style="font-family: Calibri, sans-serif;" lang="EN-US">ReplyNotify</span>函数中<span style="font-family: Calibri, sans-serif;" lang="EN-US">$this->GetReturn_code(‘</span>参数<span style="font-family: Calibri, sans-serif;" lang="EN-US">’) == "SUCCESS"</span>里面的<span style="font-family: Calibri, sans-serif;" lang="EN-US">’</span>参数<span style="font-family: Calibri, sans-serif;" lang="EN-US">’.</span></span>

<span style="font-size: 11.5pt;" lang="EN-US"> </span>

三.开始开发,按大概流程讲述:

    1.支付:首先点击支付后,会到jsapi.php文件中去,获取openid,这步我没管,也没出错;

   然后是统一下单,他会设置一大堆参数,如图:

   将里面的setNotify_url设置为你的notify.php文件所在的位置.

   其中的setOut_trade_no和setTotal_fee这两个参数是你可以随便填写的(其他参数默认可以).在支付成功后微信服务器会将这两个参数的值返回给你.我是直接将商品订单号码放到setOut_trade_no中传递过去.在这一步,我遇到的问题是,get过来的字符串参数总是放不到setOut_trade_no中,最后我发现传过来的订单字符串被莫名奇妙的加上了单引号.于是我接收到字符串后先用trim函数处理,然后就能放入了.

   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)
