今天为大家带来比较简单的支付后台处理

首先下载官方的c#模板(WxPayAPI),将模板(WxPayAPI)添加到服务器上,然后在WxPayAPI项目目录中添加两个“一般处理程序” (改名为GetOpenid.ashx、pay.ashx)

之后打开business目录下的JsApiPay.cs,在JsApiPay.cs中修改如下两处

然后在GetOpenid.ashx中加入代码如下:

public class GetOpenid : IHttpHandler  
    {  
        public string openid { get; set; }  
  
        public void ProcessRequest(HttpContext context)  
        {  
              
            string code = HttpContext.Current.Request.QueryString["code"];  
            WxPayData data = new WxPayData();  
            data.SetValue("appid", WxPayConfig.APPID);  
            data.SetValue("secret", WxPayConfig.APPSECRET);  
            data.SetValue("code", code);  
            data.SetValue("grant_type", "authorization_code");  
            string url = "https://api.weixin.qq.com/sns/oauth2/access_token?" + data.ToUrl();  
  
            //请求url以获取数据  
            string result = HttpService.Get(url);  
  
            Log.Debug(this.GetType().ToString(), "GetOpenidAndAccessTokenFromCode response : " + result);  
  
            //保存access_token,用于收货地址获取  
            JsonData jd = JsonMapper.ToObject(result);  
            //access_token = (string)jd["access_token"];  
  
            //获取用户openid  
            openid = (string)jd["openid"];  
            context.Response.Write(openid);//获取H5调起JS API参数  
            
        }  

 

在pay.ashx中加入代码如下:

public class pay : IHttpHandler  
   {  
        
       public void ProcessRequest(HttpContext context)  
       {                
           context.Response.ContentType = "text/plain";  
            
           string openid = HttpContext.Current.Request.QueryString["openid"];  
           string total_fee = HttpContext.Current.Request.QueryString["total_fee"];  
           JsApiPay jsApiPay = new JsApiPay(context);  
           jsApiPay.openid = openid;  
           jsApiPay.total_fee = int.Parse(total_fee);  
           WxPayData unifiedOrderResult = jsApiPay.GetUnifiedOrderResult();  
           context.Response.Write(jsApiPay.GetJsApiParameters());//获取H5调起JS API参数  
       }  

 

然后发布就可以了(记得将相关的信息appid等填好)

 

 

微信小程序的代码如下:

wxpay: function () {  
    var that = this  
    //登陆获取code  
    wx.login({  
      success: function (res) {  
        console.log(res.code)  
        //获取openid  
        that.getOpenId(res.code)  
      }  
    });  
  },  
  getOpenId: function (code) {  
//获取openID  
     
    var that = this;  
    wx.request({  
      url: ‘http://*******/WxPayAPI/GetOpenid.ashx?code=‘+ code ,  //改为自己的域名
      data: {},  
    //  method: ‘GET‘,  
      success: function (res) {  
      var a12=res.data  
      that.generateOrder(a12)  
      //console.log(a12)  
      },  
      fail: function () {  
        // fail  
      },  
      complete: function () {  
        // complete  
      }  
    })  
  },  
/**生成商户订单 */  
  generateOrder: function (openid) {  
    var that = this;  
    //console.log(openid)  
    //统一支付  
    wx.request({  
      url: ‘http://*******/WxPayAPI/pay.ashx‘,  //改为自己的域名
      //method: ‘GET‘,  
      data: {  
        total_fee: 1,//1分  
        openid: openid,  
      },  
      header: {  
        ‘content-type‘: ‘application/json‘  
      },  
  
      success: function (res) {  
  
        var pay = res.data  
        //发起支付  
          
        var timeStamp = pay.timeStamp;  
        var packages = pay.package;  
        var paySign = pay.paySign;  
        var nonceStr = pay.nonceStr;  
        var param = { "timeStamp": timeStamp, "package": packages, "paySign": paySign, "signType": "MD5", "nonceStr": nonceStr };  
        
        that.pay(param)  
      },  
    })  
  },  
  
  /* 支付   */  
  pay: function (param) {  
  
    wx.requestPayment({  
      timeStamp: param.timeStamp,  
      nonceStr: param.nonceStr,  
      package: param.package,  
      signType: param.signType,  
      paySign: param.paySign,  
      success: function (res) {  
        // success  
        
        wx.navigateBack({  
          delta: 1, // 回退前 delta(默认为1) 页面  
          success: function (res1) {  
            wx.showToast({  
              title: ‘支付成功‘,  
              icon: ‘success‘,  
              duration: 2000  
            });  
            
          },  
          fail: function () {  
            // fail  
              
          },  
          complete: function () {  
              
          }  
        })  
      },  
      fail: function (res) {  
        // fail  
      },  
      complete: function () {  
        // complete  
      }  
    })  
  },
