我想獲得當前用戶名，以便我可以顯示它。但我不知道該怎麼做？有任何想法嗎 ？我使用的是authservice這裏是我的角度控制器，我想獲取用戶名。如何獲取currenlty的用戶名登錄用戶authservice
myApp.controller('meetupsController', ['$scope', '$resource', function ($scope, $resource) {
var Meetup = $resource('/api/meetups');
$scope.meetups = []
Meetup.query(function (results) {
$scope.meetups = results;
});
$scope.createMeetup = function() {
var meetup = new Meetup();
meetup.name = $scope.meetupName;
meetup.$save(function (result) {
$scope.meetups.push(result);
$scope.meetupName = '';
});
}
}]);
我的主角度控制器代碼 VAR對myApp = angular.module（ '對myApp'，[ 'ngResource'， 'ngRoute']）;
myApp.config(function ($routeProvider) {
$routeProvider
.when('/', {
templateUrl: 'partials/main.html',
access: {restricted: true}
})
.when('/api/meetups', {
templateUrl: 'partials/main.html',
access: {restricted: true}
})
.when('/login', {
templateUrl: 'partials/login.html',
controller: 'loginController',
access: {restricted: false}
})
.when('/prive', {
templateUrl: 'partials/prive.html',
controller: 'userController',
access: {restricted: true}
})
.when('/logout', {
controller: 'logoutController',
access: {restricted: true}
})
.when('/register', {
templateUrl: 'partials/register.html',
controller: 'registerController',
access: {restricted: false}
})
.when('/one', {
template: '<h1>This is page one!</h1>',
access: {restricted: true}
})
.when('/two', {
template: '<h1>This is page two!</h1>',
access: {restricted: false}
})
.otherwise({
redirectTo: '/'
});
});
myApp.run(function ($rootScope, $location, $route, AuthService) {
$rootScope.$on('$routeChangeStart',
function (event, next, current) {
AuthService.getUserStatus()
.then(function(){
if (next.access.restricted && !AuthService.isLoggedIn()){
$location.path('/login');
$route.reload();
}
});
});
});
myApp.controller('meetupsController', ['$scope', '$resource', function ($scope, $resource) {
var Meetup = $resource('/api/meetups');
$scope.meetups = []
Meetup.query(function (results) {
$scope.meetups = results;
});
$scope.createMeetup = function() {
var meetup = new Meetup();
meetup.name = $scope.meetupName;
meetup.$save(function (result) {
$scope.meetups.push(result);
$scope.meetupName = '';
});
}
}]);
我的第二個角代碼：
var app = angular.module('myApp');
app.controller('loginController',
['$scope', '$location', 'AuthService',
function ($scope, $location, AuthService) {
$scope.login = function() {
// initial values
$scope.error = false;
$scope.disabled = true;
// call login from service
AuthService.login($scope.loginForm.username, $scope.loginForm.password)
// handle success
.then(function() {
$location.path('/');
$scope.disabled = false;
$scope.loginForm = {};
})
// handle error
.catch(function() {
$scope.error = true;
$scope.errorMessage = "Invalid username and/or password";
$scope.disabled = false;
$scope.loginForm = {};
});
};
$scope.posts = [];
$scope.newPost = {created_by: '', text: '', created_at: ''};
$scope.post = function(){
$scope.newPost.created_at = Date.now();
$scope.posts.push($scope.newPost);
$scope.newPost = {created_by: '', text: '', created_at: ''};
};
}]);
app.controller('logoutController',
['$scope', '$location', 'AuthService',
function ($scope, $location, AuthService) {
$scope.logout = function() {
// call logout from service
AuthService.logout()
.then(function() {
$location.path('/login');
});
};
$scope.gotoregister = function() {
$location.path('/register');
};
$scope.gotoprive = function() {
$location.path('/prive');
};
}]);
app.controller('registerController',
['$scope', '$location', 'AuthService',
function ($scope, $location, AuthService) {
$scope.register = function() {
// initial values
$scope.error = false;
$scope.disabled = true;
// call register from service
AuthService.register($scope.registerForm.username, $scope.registerForm.password)
// handle success
.then(function() {
$location.path('/login');
$scope.disabled = false;
$scope.registerForm = {};
})
// handle error
.catch(function() {
$scope.error = true;
$scope.errorMessage = "Something went wrong!";
$scope.disabled = false;
$scope.registerForm = {};
});
};
}]);
和我的服務
angular.module('myApp').factory('AuthService',
['$q', '$timeout', '$http',
function ($q, $timeout, $http) {
// create user variable
var user = null;
// return available functions for use in the controllers
return ({
isLoggedIn: isLoggedIn,
getUserStatus: getUserStatus,
login: login,
logout: logout,
register: register
});
function isLoggedIn() {
if(user) {
return true;
} else {
return false;
}
}
function getUserStatus() {
return $http.get('/user/status')
// handle success
.success(function (data) {
if(data.status){
user = true;
} else {
user = false;
}
})
// handle error
.error(function (data) {
user = false;
});
}
function login(username, password) {
// create a new instance of deferred
var deferred = $q.defer();
// send a post request to the server
$http.post('/user/login',
{username: username, password: password})
// handle success
.success(function (data, status) {
if(status === 200 && data.status){
user = true;
deferred.resolve();
} else {
user = false;
deferred.reject();
}
})
// handle error
.error(function (data) {
user = false;
deferred.reject();
});
// return promise object
return deferred.promise;
}
function logout() {
// create a new instance of deferred
var deferred = $q.defer();
// send a get request to the server
$http.get('/user/logout')
// handle success
.success(function (data) {
user = false;
deferred.resolve();
})
// handle error
.error(function (data) {
user = false;
deferred.reject();
});
// return promise object
return deferred.promise;
}
function register(username, password) {
// create a new instance of deferred
var deferred = $q.defer();
// send a post request to the server
$http.post('/user/register',
{username: username, password: password})
// handle success
.success(function (data, status) {
if(status === 200 && data.status){
deferred.resolve();
} else {
deferred.reject();
}
})
// handle error
.error(function (data) {
deferred.reject();
});
// return promise object
return deferred.promise;
}
}]);
請顯示authservice的代碼。您也可以在Cookie中設置用戶詳細信息，以便每當用戶刷新頁面時不會丟失 –
