标题: ios - 使用 Devise 通过 iOS 应用注册、登录和退出

我有一个非常基本的 Rails 应用程序，它使用 Devise 进行用户注册、登录等。我想向 iOS 应用程序公开 Devise。有很多线程是高级解释，但我对 Rails 很陌生。我基本上是向 users/sign_up 发布请求，如下所示:

AFHTTPClient *client = [AFHTTPClient clientWithBaseURL:[NSURL URLWithString"http://localhost:5000"]];
//[client defaultValueForHeader"Accept"];
[client setParameterEncoding:AFJSONParameterEncoding];
NSDictionary *params = [NSDictionary dictionaryWithObjects:[NSArray arrayWithObjects:
                                                            @"[email protected]",
                                                            @"testtest",
                                                            @"testtest",
                                                            nil]
                                                   forKeys:[NSArray arrayWithObjects:
                                                            @"email",
                                                            @"password",
                                                            @"password_confirmation",
                                                            nil]];

[client registerHTTPOperationClass:[AFHTTPRequestOperation class]];
NSURLRequest *request = [client requestWithMethod"GET" path"/users/sign_up" parameters:params];
AFHTTPRequestOperation *operation = [AFJSONRequestOperation JSONRequestOperationWithRequest:request success:^(NSURLRequest *request, NSHTTPURLResponse *response, id JSON) {
    NSLog(@"%@", JSON);
    NSLog(@"%@", [response allHeaderFields]);
} failure:^(NSURLRequest *request, NSHTTPURLResponse *response, NSError *error, id JSON) {
}];

[operation setAcceptableContentTypes:[NSSet setWithObjects"application/json", @"text/json", @"text/javascript", @"text/plain",@"text/html", nil]];
[operation start];

当我收到 200 OK 时，这似乎在 iOS 端进行:

   2013-01-21 13:38:00.412 Starfish[35773:c07] I 
restkit.network:RKHTTPRequestOperation.m:152 GET 'http://localhost:5000/signup?password=testtest&password_confirmation=testtest&email=first.last%40gmail.com'

2013-01-21 13:38:01.073 Starfish[35773:7207] I restkit.network:RKHTTPRequestOperation.m:179 GET 'http://localhost:5000/signup?password=testtest&password_confirmation=testtest&email=first.last%40gmail.com' (200 OK) [0.6611 s]
2013-01-21 13:38:01.074 Starfish[35773:c07] {
    "Cache-Control" = "max-age=0, private, must-revalidate";
    Connection = close;
    "Content-Type" = "text/html; charset=utf-8";
    Etag = "\"5dfe88700e41a015a8f524850446e327\"";
    Server = "thin 1.5.0 codename Knife";
    "Set-Cookie" = "_geo-photo_session=BAh7B0kiD3Nlc3Npb25faWQGOgZFRkkiJTEyZTJjMjFkZjAwZGZlMWIzMTJmNTg5ODNkNjM5OGI0BjsAVEkiEF9jc3JmX3Rva2VuBjsARkkiMTN4eUZGUzVhb1pIdXc1QlJJUnBxSFVrZmYvUDdpeGtaeklxNGhOejFOeEk9BjsARg%3D%3D--5130edc939facbe7004570141c069d40f5f7feca; path=/; HttpOnly";
    "X-Request-Id" = a2480798afed4e7aca17f3f1e2d3d44d;
    "X-Runtime" = "0.219984";
    "X-UA-Compatible" = "IE=Edge";
}

在 Rails 方面:

Started GET "/signup?password=[FILTERED]&password_confirmation=[FILTERED]&email=first.last%40gmail.com" for 127.0.0.1 at 2013-01-21 13:38:00 -0800
13:43:15 web.1  | Processing by Devise::RegistrationsController#new as */*
13:43:15 web.1  |   Parameters: {"password"=>"[FILTERED]", "password_confirmation"=>"[FILTERED]", "email"=>"[email protected]"}
13:43:15 web.1  |   Rendered devise/shared/_links.erb (2.1ms)
13:43:15 web.1  |   Rendered devise/registrations/new.html.erb within layouts/application (23.7ms)
13:43:15 web.1  | Completed 200 OK in 142ms (Views: 64.9ms | ActiveRecord: 6.9ms)

开箱即用注册:

<h2>Sign up</h2>

<%= form_for(resource, :as => resource_name, :url => registration_path(resource_name)) do |f| %>
  <%= devise_error_messages! %>

  <div><%= f.label :email %><br />
  <%= f.email_field :email, :autofocus => true %></div>

  <div><%= f.label :password %><br />
  <%= f.password_field :password %></div>

  <div><%= f.label :password_confirmation %><br />
  <%= f.password_field :password_confirmation %></div>

  <div><%= f.submit "Sign up" %></div>
<% end %>

<%= render "devise/shared/links" %>

我不知道 Rails 足以解决的问题是我不希望呈现任何 View 。我只是想将注册或登录凭据作为 JSON 对象传递并接收用户已创建或登录的验证。我上面的内容不是创建用户，因为它正在尝试呈现 View 。任何帮助将不胜感激。谢谢。

Best Answer-推荐答案

我正在做类似的事情，到目前为止，它的注册部分通过 CURL 使用 JSON(应该很容易转换为 iOS)以及通过浏览器工作。使用 this answer 的修改来自 NeverBe :

我修改了 config/initializers/devise.rb 并添加了这一行:

config.navigational_formats = ["*/*", "/", :html, :json]

---

我修改了 config/routes.rb 并替换了这一行:

devise_for :users

用这一行:

devise_for :users, :controllers => {:registrations => "registrations"}

---

我创建了一个新文件 app/controllers/registrations_controller.rb

class RegistrationsController < Devise::RegistrationsController

  def create
    respond_to do |format|
      format.html {
        super
      }
      format.json {
        if params[:user][:email].nil?
          render :status => 400,
                 :json => {:message => 'User request must contain the user email.'}
          return
        elsif params[:user][:password].nil?
          render :status => 400,
                 :json => {:message => 'User request must contain the user password.'}
          return
        end

        if params[:user][:email]
          duplicate_user = User.find_by_email(params[:user][:email])
          unless duplicate_user.nil?
            render :status => 409,
                   :json => {:message => 'Duplicate email. A user already exists with that email address.'}
            return
          end
        end

        @user = User.create(params[:user])

        if @user.save
          render :json => {:user => @user}
        else
          render :status => 400,
                 :json => {:message => @user.errors.full_messages}
        end
      }
    end
  end
end

附加说明:即使没有所有自定义错误处理代码，您仍然可以获得错误处理，但我想返回状态代码错误(400 和 409)而不是带有自定义错误消息的 200，这是我从默认设计中得到的行为。
