一、獲取微信支付 MCHID,KEY,APPID,APPSecret 四個支付關鍵值.
微信支付商戶平臺 https://pay.weixin.qq.com/index.php/core/home/login?return_url=%2F
1.登錄微信支付商戶平臺獲取到商戶號(MCHID),
2.在"賬號中心"欄目下"API安全"欄目里設置API密鑰(KEY)
微信公眾號： https://mp.weixin.qq.com/
1.登錄微信公眾在"基本配置"欄獲取應用ID(APPID)和應用密鑰(APPSecret)
2.在"接口權限"欄目下"網頁賬號"綁定正式支付的域名 (如:××××.net,不要http:和"/"斜杠)
3.在"微信支付"欄目下"開發配置"里面設置公眾支付的支付授權目錄(如:××××.net/WeChatWeb/)
二、把WxPayAPI添加到制作項目中,在Config.cs文件里修改獲取到的MCHID,KEY,APPID,APPSecret四個關鍵值以及NOTIFY_URL值(NOTIFY_URL是支付授權目錄),并在MVC項目里建一個WeChatWeb控制器,里面加上邏輯代碼.并傳遞微信jsapi支付所需的參數.代碼示例如下:
