Question

我一直在尝试使用离子angularjs中的$ http请求连接到后端服务器。我想使用API注册用户。有人能告诉我我的代码有什么问题吗？这是我的controller.js

angular.module('app.Auth', [])

.factory('Auth', ['$q', '$http', '$localStorage', 'URL', function($q, $http, $localStorage, URL) {

return {
    register: function(data, success, error) {
        $http.post(URL.api + 'register', data).success(success).error(error)
    }
};
}])
.controller('SignupCtrl', function($scope, $rootScope, $timeout, $stateParams, ionicMaterialInk,Auth,$localStorage,$state,Auth,URL) {

$scope.signupError = function(msg){
    if(msg.status == false){
        $scope.errors = msg.errors;
    }else{
        $scope.errors = ['Error accessing API.'];
    }
};


$scope.signupSuccess = function(response){
    if(response.status==false){
        $scope.errors = response.errors;
    }else{
        alert("success!");
    }

};

$scope.user = {
    firstname:'',
    middlename:'',
    lastname:'',
    password: '',
    email: ''
};

$scope.signupEmail = function(){
    Auth.register($scope.user,$scope.signupSuccess,$scope.signupError);
};
});

这是我的signup.html

<ion-view view-title="Sign Up" name="signup">
<ion-content>
  <div class="list">
   <div ng-if="errors.length > 0" class="error_bg" ng-repeat="error in errors">
            <p class="error" ng-bind="error"></p>
        </div>
    <label class="item item-input item-floating-label">
        <span class="input-label">First Name</span>
        <input type="text" placeholder="First Name" style="color:purple; font-size:18px" ng-model="user.firstname">
    </label>
    <label class="item item-input item-floating-label">
        <span class="input-label">Middle Name</span>
        <input type="text" placeholder="Middle Name" style="color:purple; font-size:18px" ng-model="user.middlename">
    </label>
    <label class="item item-input item-floating-label">
        <span class="input-label">Last Name</span>
        <input type="text" placeholder="Last Name" style="color:purple; font-size:18px" ng-model="user.lastname">
    </label>
    <label class="item item-input item-floating-label">
        <span class="input-label">Email Address</span>
        <input type="text" placeholder="Email Address" style="color:purple; font-size:18px" ng-model="user.email">
    </label>
    <label class="item item-input item-floating-label">
        <span class="input-label">Password</span>
        <input type="password" placeholder="Password" style="color:purple; font-size:18px" ng-model="user.password">
    </label>
    </div>
  <button class="button button-block button-royal" style="background-color:blue" ng-click="signupEmail()">Continue</button>

注意$http.post的正确sintax。

实际上，$http.post()返回 promise ，其方法then()有两个参数（成功和错误处理程序），因此您的HTTP请求注册服务应该被重写从：

$http.post(URL.api + 'register', data).success(success).error(error);

为：

$http.post(URL.api + 'register', data).then(success, error);
