Question

我查看了所有相关的StackOverflow页面，似乎没有任何东西适用于我的情况。我试过console.log（响应），它只是说对象对象。我不清楚为什么在我之前获得“欢迎”时，我的应用程序上的“欢迎未定义”。

应用程序/实/ facebook.js：

HashMap

应用程序/实/ facebook.html：

'use strict';

angular.module('ngSocial.facebook', ['ngRoute', 'ngFacebook'])

.config(['$routeProvider', function($routeProvider) {
  $routeProvider.when('/facebook', {
    templateUrl: 'facebook/facebook.html',
    controller: 'FacebookCtrl'
  });
}])

.config( function( $facebookProvider ) {
  $facebookProvider.setAppId('1410425285653598');
  $facebookProvider.setPermissions("email, public_profile, user_posts, publish_actions, user_photos");
})

.run(function($rootScope){
    (function(d, s, id){
     var js, fjs = d.getElementsByTagName(s)[0];
     if (d.getElementById(id)) {return;}
     js = d.createElement(s); js.id = id;
     js.src = "//connect.facebook.net/en_US/sdk.js";
     fjs.parentNode.insertBefore(js, fjs);
   }(document, 'script', 'facebook-jssdk')); 
})

.controller('FacebookCtrl', ['$scope', '$facebook', function($scope, $facebook) {
    $scope.isLoggedIn = false;

    $scope.login = function(){
        $facebook.login().then(function(){
            $scope.isLoggedIn = true;
            refresh();
        });
    }


    $scope.logout = function(){
        $facebook.logout().then(function(){
            $scope.isLoggedIn = false;
            refresh();
        });
    }

    function refresh(){
        $facebook.api("/me",{fields:'last_name, first_name, email, gender, locale, link'}).then(function(response){
            $scope.welcomeMsg = "Welcome "+ response.name;
            $scope.isLoggedIn = true;
            $scope.userInfo = response;
            $facebook.api('/me/picture').then(function(response){
                $scope.picture = response.data.url;
                $facebook.api('/me/permissions').then(function(response){
                    $scope.permissions = response.data;
                    $facebook.api('/me/posts').then(function(response){
                        $scope.posts = response.data;
                    });
                });
            });
        },
        function(err){
            $scope.welcomeMsg = "Please Log In";
        });
    }

    $scope.postStatus = function(){
        var body = this.body;
        $facebook.api('/me/feed', 'post', {message: body}).then(function(response){
            $scope.msg = 'Thanks for Posting';
            refresh();
        });
    }

    refresh();
}]);

应用/ index.html中：

  <div class="col-md-4">
    <h4>{{welcomeMsg}}</h4>

Answer 1

你的问题是facebook.api电话中的这一行。

$scope.welcomeMsg = "Welcome "+ response.name;

如果我不得不从查看代码（不熟悉facebook api）猜测，看起来好像你要求facebook提供first_name和last_name，而不是名字。所以我怀疑你要找的代码行是

$scope.welcomeMsg = "Welcome "+ response.first_name + " " + response.last_name;

Answer 2

这取决于ngFacebook API如何返回response对象，但我的钱是在data属性中。请改为response.data.name。

（您还可以在控制台将其记录到任何称职的开发工具（如Chrome）后展开response对象，并手动查看其属性。）

为什么我的response.name未定义？
