不废话，看代码

onLaunch: function() {
   var _this = this;
   var url=this.globalData.url+"WeiXinConfig";
   wx.request({
     method: 'POST',
     url:url,
     header:{
       'content-type':'application/json'
     },success(res) {
       var Resdata=JSON.parse(res.data.d);
       if(Resdata[0]!=undefined){
         wx.login({
           //获取code
           success: function (res) {
             var code = res.code; //返回code
             var appId = Resdata[0].appid;
             var secret = Resdata[0].appsecret;
             wx.request({
               url: 'https://api.weixin.qq.com/sns/jscode2session?appid=' + appId + '&secret=' + secret + '&js_code=' + code + '&grant_type=authorization_code',
               data: {},
               header: {
                 'content-type': 'json'
               },
               success: function (res) {
                 var openid = res.data.openid //返回openid
                 console.log('openid为' + openid);
                 console.log('appid为' + Resdata[0].appid);
                 console.log('appsecret为' + Resdata[0].appsecret);
                 if(openid!=undefined){
                   wx.setStorageSync("openid",openid);
                   // wx.setStorageSync("appid",Resdata[0].appid);
                   // wx.setStorageSync("appsecret",Resdata[0].appsecret);
                 }
               }
             })
           }
         })
       }
     }
   });
