Question

前台代码
var data={"UserName":account,"Password":pass};
$.ajax({
** url:"/My/signIn", **
data:data,
type:"POST",
beforeSend:function(){
$.loading();
},
success:function(res){

// if(res.Code==0){
// var index=window.location.href.indexOf('ReturnUrl=');

// window.location.replace(decodeURIComponent(window.location.href.substring(index + 10)));
// }else{
// mui.toast(res.Message);
// }
$.loadover();
},
error:function(res){
$.loadover();
// mui.toast(res.Message);
}
});

    //后台代码
    //路由
    module.exports =function(app){
        app.get(['/','/Home/index'],index.getter);//首页
        app.get('/My/login',login.showlogin);//登录
    **  app.post('/My/signIn',login.signIn);**
    }

    //控制器
    var request = require('request');
    module.exports={
        'showlogin':function(req,res,next){
            res.render('My/login.html',{});
        },  
        'signIn':function(req,res){
            cosnole.log(111111);
            res.render('My/login.html',{});
        }
    }
