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: 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 } }) },
