Question

我目前有一个我想要使用的JSON对象。这是我对它进行字符串化，因为localStorage只能有字符串：

$http.post('http://localhost:8000/refresh', {
  name: $scope.name,
  email: $scope.email,
  token: $rootScope.devToken,
  platform: ionic.Platform.platform()
}).then(function(response) {
  console.log("Saving profile");

  window.localStorage.setItem("UserProfile", JSON.stringify(response.data));

  $state.go('home');
});

当我console.log(response.data)时，会输出正确的数据。然后我来自 localStorage ：

var temp = window.localStorage.getItem("UserProfile");
var profile = JSON.parse(temp);
console.log("Profile: " + profile);

当我console.log(profile)时，我得到了Object对象。我究竟做错了什么？当我console.log(temp)时，我得到了大量正确的数据。但我不希望它成为一个字符串。我需要它回到一个对象。

编辑： JSON：

[
		{
			userProfileID: 1,
			firstName: 'Austin',
			lastName: 'Hunter',
			email: 'ahunasdfgk.com',
			token: '',
			platform: '',
			password: 'inc3',
			companyProfileID: 1,
			authentication: '',
			UserTopics: [
				{
					topicID: 1,
					topicName: 'Needs Maintenance',
					alertLevel: 'Urgent',
					TopicDepartments: [
						{
							departmentID: 1,
							departmentName: 'Shop',
							required: false,
							DepartmentUsers: [
								{
									userProfileID: 1,
									firstName: 'Austin',
									lastName: 'Hunter',
									email: 'ahunook.com',
									token: '',
									platform: '',
									companyProfileID: 1
								}, {
									userProfileID: 2,
									firstName: 'Ashley',
									lastName: 'Jeanette',
									email: 'ashlhgfdail.com',
									token: '',
									platform: '',
									companyProfileID: 1
								}
							]
						}
					]
				}, {
					topicID: 2,
					topicName: 'Help',
					alertLevel: 'Urgent',
					TopicDepartments: [
						{
							departmentID: 1,
							departmentName: 'Shop',
							required: false,
							DepartmentUsers: [
								{
									userProfileID: 1,
									firstName: 'Austin',
									lastName: 'Hunter',
									email: 'afafaf@oook.com',
									token: '',
									platform: '',
									companyProfileID: 1
								}
							]
						}, {
							departmentID: 2,
							departmentName: 'Office',
							required: false,
							DepartmentUsers: [
								{
									userProfileID: 1,
									firstName: 'Ashley',
									lastName: 'Jeanette',
									email: 'ashfafaff.com',
									token: '',
									platform: '',
									companyProfileID: 1
								}
							]
						}
					]
				}
			]
		}
	];

而console.log（个人资料）给了我这个：

[Log] Array (1) (controllers.js, line 65)
0 Object

UserTopics: [Object, Object] (2)

_id: "57e078cc62e223290851c2c1"

authentication: ""

companyProfileID: 1

email: "ahun______.com"

firstName: "Austin"

lastName: "Hunter"

password: "inco_______23"

platform: ""

token: ""

userProfileID: 1

Answer 1

尝试console.log(profile)。您的方法将“配置文件”转换为String。因此给出了[Object Object]。在您的情况下，要获取email，请使用profile [0] .email作为您的调用返回数组而不是JSON对象。

Answer 2

你的方法是正确的

console.log( profile); will print correct object

这可能是跨域政策问题。看看这篇文章。
