微信企業付款開發 C#

1、第一步：須要準備的東東

     <add key="sAppID" value="wxf2303b260*******"/>　　　　                       // 開發者應用ID ，如圖一

     <add key="sAppSecret" value="5b83018b0b69c4231c14a2a25*******"/>    //開發者應用密鑰，如圖一

     <add key="sPartnerKey" value="E07D38C4EC0C9B42BF808633*******"/>   //商戶祕鑰           如圖二

     <add key="sPartner" value="**********"/>  　　　　　　　　　　　　　　　　// 商戶號            申請微信支付經過後，收到的郵件裏面有， 10位的商戶號

 

    

    (圖一)，登陸地址：https://mp.weixin.qq.com/

 

     

 （圖二，你本身設置的32位祕鑰），登陸地址：https://pay.weixin.qq.com/index.php/home/login?return_url=%2F

 

 

2、第二步：安裝證書，windows下面選擇.p12格式的證書；取證書時必定得用 絕對路徑（如：D:\wwwroot\BusinessCard\weixin\businesscard\cert\apiclient_cert.p12）

      證書pkcs12格式 (apiclient_cert.p12)

 

3、第三步：賬戶裏面必須有錢，以下圖

    

 

4、第四步：源碼以下：
