在我的回复中,如果我输入无效字段,它会显示来自服务器(节点)的“无效的用户名或密码”消息。但我不知道如何在我的模板中填充它。我尝试了很多例子,但没有一个适合我。如何为它编写服务和控制器? TIA
模板:
<div ng-if="messages.error" role="alert" class="alert alert-danger">
<div ng-repeat="error in messages.error">{{error.msg}}</div>
</div>
<form name="frmRegister" ng-submit="login()" role="form">
<legend>Log In</legend>
<div class="form-group" ng-class="{ 'has-error': frmRegister.email.$dirty && frmRegister.email.$error.required }">
<label for="email">Email</label>
<input type="email" name="email" id="email" placeholder="Email" class="form-control" ng-model="user.email" required>
<span ng-show="frmRegister.email.$dirty && frmRegister.email.$error.required" class="help-block">Email is required</span>
</div>
<div class="form-group" ng-class="{ 'has-error': frmRegister.password.$dirty && frmRegister.password.$error.required }">
<label for="password">Password</label>
<input type="password" name="password" id="password" placeholder="Password" class="form-control" ng-model="user.password"
required>
<span ng-show="frmRegister.password.$dirty && frmRegister.password.$error.required" class="help-block">Password is required</span>
</div>
<button type="submit" id="submit" class="btn btn-success">Log in</button>
</form>
控制器:
angular.module('MyApp')
.controller('LoginCtrl', function($scope,$rootScope, $location, $auth, toastr, $http) {
$scope.login = function() {
$http ({
method : 'POST',
url: 'http://localhost:3000/onio/v1/login',
data : $scope.user
});
$auth.login($scope.user)
.then(function() {
toastr.success('You have successfully signed in!');
$location.path('/');
})
.catch(function(error) {
toastr.error(error.data.message, error.status);
});
};
$scope.authenticate = function(provider) {
$auth.authenticate(provider)
.then(function() {
$rootScope.currentUser = response.data.user;
toastr.success('You have successfully signed in with ' + provider + '!');
$location.path('/');
})
.catch(function(error) {
if (error.message) {
// Satellizer promise reject error.
toastr.error(error.message);
} else if (error.data) {
// HTTP response error from server
toastr.error(error.data.message, error.status);
} else {
toastr.error(error);
}
});
};
});

您需要将错误数据从服务器绑定到范围,以便可以在模板中使用它。在你的catch块中尝试:
.catch(function(error) {
$scope.error_message = error.data.message
toastr.error(error.data.message, error.status);
});
然后在html中,您可以在任何需要的地方绑定该错误消息:
<div ng-if="error_message" role="alert" class="alert alert-danger">
<div>{{error_message}}</div>
</div>
