php微信支付（僅Jsapi支付）詳細步驟.----僅適合第一次做微信開發的程式設計師

本人最近做了微信支付開發,是第一次接觸.其中走了很多彎路,遇到的問題也很多其中走了很多彎路,遇到的問題也很多的新人不再遇到類似的問題,我把我的開發步驟和問題寫出來,以供參考

.

開發時間是2016/8/2,所以微信支付的版本也是對應此時的版本

.

一.前期準備：

首先你們公司開通微信支付功能後，會收到一份郵件，裡面有帳戶相關信息，一般有：微信支付商戶號，商戶平台登錄帳號，商戶平台登錄密碼，申請對應的公眾號，公眾號APPID

。 🎜🎜

1.下載demo1.下載demo：用上面資訊登陸“微信商家平台”，>>>（右上角開發文件）> >sdk下載>>>選php

2.下載證書：帳戶中心>>>api安全

3.配置好後去微信公眾平台,裡面有微信支付功能如下圖.在開發配置中設定支付目錄和測試目錄目錄,支付目錄可以先不管(我的網域是www.test.com),然後將自己的微訊號加入測試白名單

.

 

 

    4.再去微信公眾平台>>>開發>>>接口權限>>>網頁服務的第一項`網頁賬號 `,修改它的值為你自己的網域名稱(僅僅是網域名稱).如圖:

 

 

 

二.demo程式碼修改(僅針對目前的版本):

     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']);

   改为:

   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.付款:先點擊付款後,會到jsapi.php ,也沒出錯;    然後是統一下單,他會設置一大堆參數,

如圖

:    將裡面的setNotify_url

設定為你的notify.php

檔案所在的位置

.檔案所在的位置.

   其中的setOut_trade_no和setTotal_fee這兩個參數是你可以隨便填寫的個參數的值回給你.我是直接將商品訂單號碼放到setOut_trade_no我是直接將商品訂單號碼放到setOut_trade_no中傳遞過去.在這一步中傳遞過去.在這一步中傳遞過去 ,get過來的字串參數總是放不到setOut_trade_no中,最後我發現傳過來的訂單字符串被莫名奇妙的加上了單引號最後我發現傳過來的訂單字符串被莫名奇妙的加上了單引號.接收到字串後先用trim函數處理,然後就能放入了.

   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)
