一、获取微信支付 MCHID,KEY,APPID,APPSecret 四个支付关键值.
微信支付商户平台 https://pay.weixin.qq.com/index.php/core/home/login?return_url=%2F
1.登录微信支付商户平台获取到商户号(MCHID),
2.在"账号中心"栏目下"API安全"栏目里设置API密钥(KEY)
微信公众号： https://mp.weixin.qq.com/
1.登录微信公众在"基本配置"栏获取应用ID(APPID)和应用密钥(APPSecret)
2.在"接口权限"栏目下"网页账号"绑定正式支付的域名 (如:××××.net,不要http:和"/"斜杠)
3.在"微信支付"栏目下"开发配置"里面设置公众支付的支付授权目录(如:××××.net/WeChatWeb/)
二、把WxPayAPI添加到制作项目中,在Config.cs文件里修改获取到的MCHID,KEY,APPID,APPSecret四个关键值以及NOTIFY_URL值(NOTIFY_URL是支付授权目录),并在MVC项目里建一个WeChatWeb控制器,里面加上逻辑代码.并传递微信jsapi支付所需的参数.代码示例如下:
