如何从控制器页面redirect页面？ – Nodejs

login控制器 –

var myapp = angular.module('myApp', ['ngRoute']); myapp.config(["$routeProvider", function($routeProvider) { $routeProvider .when('/addusers', { controller: 'addusersctrl', templateUrl: '../views/addusers.html' }) .otherwise({ redirectTo: '/' }); }]); myapp.controller('loginctrl', ['$scope', '$route', '$http', '$routeParams', '$location', function($scope, $route, $http, $routeParams, $location) { console.log("im a controller"); $scope.login = function() { //console.log($scope.user); // $http.post('/login',$scope.user).success(function(response){ // console.log(response); // }); $http({ method: 'post', url: '/login', data: $scope.user }).then(function successCallback(response) { // this callback will be called asynchronously // when the response is available console.log('Inside controller'); // console.log(response.data+" "+location); //$window.location.href = 'addusers.html'; //window.location.href = '/views/addusers.html'; $location.path("/addusers"); }, function errorCallback(response) { console.log(response.data); // called asynchronously if an error occurs // or server returns response with an error status. }); }; }]); myapp.controller('addusersctrl',['$scope','$http',function($scope,$http){ console.log("im a controller"); $scope.login = function() { //console.log($scope.user); // $http.post('/login',$scope.user).success(function(response){ // console.log(response); // }); $http({ method: 'post', url: '/login', data: $scope.user }).then(function successCallback(response) { // this callback will be called asynchronously // when the response is available console.log(response.data); //$window.location.href = 'addusers.html'; }, function errorCallback(response) { console.log(response.data); // called asynchronously if an error occurs // or server returns response with an error status. }); }; }]); 

Server.js –

  var express = require('express') var app = express() var mongojs = require('mongojs'); var db = mongojs('userlogin',['userlogin']); var bodyParser = require('body-parser'); // var exphbs = require('express-handlebars'); var path = require('path'); var routes = require('./routes/index'); var users; users = require('./routes/users'); app.set('views', path.join(__dirname, 'views')); app.engine('html', exphbs({defaultLayout:'layout'})); app.set('view engine', 'html'); app.use(express.static(path.join(__dirname,'public'))); app.use(bodyParser.json()); //var Client = require('node-rest-client').Client; //var client = new Client(); var request = require('request'); app.post('/login',function(req, res){ console.log(req.body); // // direct way uncomment this and try to http request // client.post("http://192.168.1.6:8080/RestTGRP/TGRP/checkAPI", function (data, response) { // // parsed response body as js object // //console.log(data); // // raw response // console.log(response); // //res.send(response); // }); // this is another method to call client var options = { uri : 'http://192.168.1.6:8080/RestTGRP/TGRP/checkAPI', method : 'post' }; var resss = ''; request(options, function (error, response, body) { if (!error && response.statusCode == 200) { resss = body; } else { resss = 'Not Found'; } console.log(body); //res.json(resss); }); // this is to validate the user db.collection('userlogin').findOne({name: req.body.name}, function(err, user) { console.log('inside validation'); console.log(err); console.log(user); // In case the user not found if(!user) { console.log('THIS IS ERROR RESPONSE') res.json("user not found!") } else{ console.log('User found '); if (user.password === req.body.password){ console.log('User and password is correct'); // alert('inside user login'+res); res.json("login successfully"); //res.render('addusers'); } else { console.log("Credencials wrong"); res.json("wrong password"); } } }); }); app.use('/', routes); app.use('/users', users); app.listen(8000, function(){ console.log("running successfully in 8000"); }); 

每当我们试图从login导航到addusers页面，我们得到404页面找不到错误。 如何从控制器页面redirect页面？

这很可能是您在路由configuration中提供了templateUrl的方式。 我的build议是找出你的docroot，它最有可能是nodejs的项目文件夹，并提供一个完整的path相对于templateUrl中的docroot，而不是“../”样式表示。 你要做的是提供templateUrl相对于login控制器。

例如，如果您的项目结构是：

  nodeproject/ |-> js/ |-> loginPage/ |-> views/ 

您在routeConfig中的templateUrl将是：

 myapp.config(["$routeProvider", function($routeProvider) { $routeProvider .when('/addusers', { controller: 'addusersctrl', templateUrl: '/loginPage/views/addusers.html' }) .otherwise({ redirectTo: '/' }); }]);
