ios - 使用 Devise 通过 iOS 应用注册、登录和退出
<p><p>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:</p>
<pre><code>AFHTTPClient *client = ];
//;
;
NSDictionary *params = [NSDictionary dictionaryWithObjects:[NSArray arrayWithObjects:
@"[email protected]",
@"testtest",
@"testtest",
nil]
forKeys:[NSArray arrayWithObjects:
@"email",
@"password",
@"password_confirmation",
nil]];
];
NSURLRequest *request = ;
AFHTTPRequestOperation *operation = [AFJSONRequestOperation JSONRequestOperationWithRequest:request success:^(NSURLRequest *request, NSHTTPURLResponse *response, id JSON) {
NSLog(@"%@", JSON);
NSLog(@"%@", );
} failure:^(NSURLRequest *request, NSHTTPURLResponse *response, NSError *error, id JSON) {
}];
];
;
</code></pre>
<p>当我收到 200 OK 时，这似乎在 iOS 端进行:</p>
<pre><code> 2013-01-21 13:38:00.412 Starfish I

<p>在 Rails 方面:</p>
<pre><code>Started GET "/signup?password=&password_confirmation=&email=first.last%40gmail.com" for 127.0.0.1 at 2013-01-21 13:38:00 -0800

</code></pre>
<p>开箱即用注册:</p>
<pre><code><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" %>
</code></pre>
<p>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。</p></p>

<p><p>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 <a href="https://stackoverflow.com/questions/14792746/create-a-user-account-with-devise-via-a-native-ios-app" title="this answer" rel="noreferrer noopener nofollow">this answer</a> 的修改来自 <a href="https://stackoverflow.com/users/1025520/neverbe" rel="noreferrer noopener nofollow">NeverBe</a> :</p>
<p>我修改了 <strong>config/initializers/devise.rb</strong> 并添加了这一行:</p>
<pre><code>config.navigational_formats = ["*/*", "/", :html, :json]
</code></pre>
<hr/>
<p>我修改了 <strong>config/routes.rb</strong> 并替换了这一行:</p>
<pre><code>devise_for :users
</code></pre>
<p>用这一行:</p>
<pre><code>devise_for :users, :controllers => {:registrations => "registrations"}
</code></pre>
<hr/>
<p>我创建了一个新文件 <strong>app/controllers/registrations_controller.rb</strong></p>
<pre><code>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
</code></pre>
<p>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。</p></p>
