使用Devise注册，登录并使用iOS应用程序登录 [英] Using Devise to sign up, sign in and sign out with an iOS app
问题描述
我有一个非常基本的Rails应用程序，使用Devise进行用户注册，登录等。我想将Devise公开到iOS应用程序。有很多线程是高级别的解释，但我是Rails的新手。我基本上是向用户/ sign_up发出请求，如下所示：
I have a very basic Rails app that uses Devise for user sign up, sign in, etc. I'd like to expose Devise to an iOS app. There's a lot of threads that are high level explanations, but I'm very new to Rails. I'm basically posting a request to users/sign_up like so:
AFHTTPClient *client = [AFHTTPClient clientWithBaseURL:[NSURL URLWithString:@"http://localhost:5000"]];
//[client defaultValueForHeader:@"Accept"];
[client setParameterEncoding:AFJSONParameterEncoding];
NSDictionary *params = [NSDictionary dictionaryWithObjects:[NSArray arrayWithObjects:
@"first.last@gmail.com",
@"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];
这似乎在iOS端正在经历，因为我收到200 OK：
This seems to be going through on the iOS side as I receive a 200 OK:

在Rails端：

-box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" %>
我不知道的Rails足以解决的问题是，我不想任何提交的视图。我只想将注册或登录凭据作为JSON对象传递，并接收用户创建或登录的验证。我上面所提到的不是创建用户，因为它试图渲染视图。任何帮助将不胜感激。谢谢。
The problem, which I don't know Rails enough to solve, is that I don't want any views rendered. I simply want to pass the sign up or login credentials as JSON objects and receive a validation that the user was created or signed in. What I have above isn't creating the user because it's attempting to render a view. Any help would be greatly appreciated. Thanks.
推荐答案
我正在做一个类似的事情，并通过使用JSON的CURL将其注册部分工作到目前为止（应该易于转换为iOS），也可以通过浏览器。使用的修改来自 NeverBe 的此答案：
I'm doing a similar thing, and have the sign up part of it working so far via CURL using JSON (which should translate to iOS easily), and also via the browser. Using a modification of this answer from NeverBe:
我已修改 config / initializers / devise.rb 并添加了以下行：
I modified config/initializers/devise.rb and added the line:
config.navigational_formats = ["*/*", "/", :html, :json]
我修改了 config / routes.rb 并替换这一行：
devise_for :users
与此行：
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，您仍然会收到错误处理，但是我想返回状态代码错误（400和409）而不是200，其中包含自定义错误消息我从默认设计行为中获得了什么。
Additional note: You still get error handling even without all that custom error handling code, but I wanted to return status code errors (400 and 409) instead of 200 with custom error messages which is what I was getting from the default devise behavior.
