从JSON创建Devise用户 [英] Create User in Devise from JSON

问题描述

我正在将我的Rails 3.1应用程序与我的iOS应用程序集成在一起，运行Devise进行用户身份验证。我希望用户能够从应用程序注册，然后我可以存储这些凭据以便稍后登录。

I'm working on integrating my Rails 3.1 app running Devise for user authentication with my iOS app. I'd like the user to be able to register from the application, and then I can store those credentials to login later.

使用RestKit，我这样做： p>

Using RestKit, I do this:

-(IBAction)registerUser:(id)sender {
    NSDictionary *params = [NSDictionary dictionaryWithObjects:[NSArray arrayWithObjects:
                                                                self.email.text,
                                                                self.password.text,
                                                                self.confirmPassword.text,
                                                                nil]
                                                       forKeys:[NSArray arrayWithObjects:
                                                                @"email",
                                                                @"password",
                                                                @"password_confirmation",
                                                                nil]];

    [[RKClient sharedClient] post:@"/users.json" params:params delegate:self];
}

/users.json url转到： user_registration POST /users(.:format）{：action =>create，：controller =>devise / registrations} 根据耙子路线）。看来，post调用接受不同的格式，所以我认为它会接受JSON。我的帖子请求被序列化为JSON，并被发送。服务器得到它，这是日志：

The /users.json url goes to: user_registration POST /users(.:format) {:action=>"create", :controller=>"devise/registrations"} (according to rake routes). It appears that the post call accepts different formats, so I assume it will accept JSON. My Post request is serialized as JSON, and sent off. The server gets it, and this is the log:

Started POST "/users.json" for 129.21.84.10 at 2012-01-12 15:33:57 -0500
  Processing by Devise::RegistrationsController#create as JSON
  Parameters: {"password"=>"[FILTERED]", "password_confirmation"=>"[FILTERED]", "email"=>"[e-mail]"}

   (0.2ms)  BEGIN
   (0.4ms)  ROLLBACK
Completed 422 Unprocessable Entity in 93ms (Views: 3.8ms | ActiveRecord: 10.2ms)

我收到一个422错误，我的用户没有创建。我的iOS应用程序得到的响应是：响应：{电子邮件：[不能为空]，密码：[不能为空]} 。但是密码和电子邮件不是空白的，服务器成功获取。所以，一些事情是不正常的，我不知道去哪里。如何使用JSON创建用户？

I get a 422 error, and my user is not created. The response my iOS app gets is: Response: {"email":["can't be blank"],"password":["can't be blank"]}. But the password and email isn't blank, the server got them successfully. So, something isn't working right, and I'm not sure where to go. How can I create the user using JSON?

感谢您的帮助！

推荐答案

您的rails应用程序期待JSON格式：

Your rails app is expecting JSON in this form :

{"user":{"email":"[e-mail]", "password":"Test123", "password_confirmation":"Test123"}}

但是默认情况下RestKit发送：

But by default RestKit is sending this :

{"email":"[e-mail]", "password":"Test123", "password_confirmation":"Test123"}

要添加user，您只需要设置rootKeyPath如下所示：

To add "user" you just need to set the rootKeyPath like this:

RKObjectMapping *userSerializationMapping = [userMapping inverseMapping];
userSerializationMapping.rootKeyPath = @"user";
[[RKObjectManager sharedManager].mappingProvider setSerializationMapping:userSerializationMapping forClass:[User class]];
