通过json的Devise失败认证发回html而不是json [英] Devise failure authentication via json sends back html instead of json

问题描述

我已经设法设置了json身份验证。我实现了以下代码：

  class Users :: SessionsController< Devise :: SessionsController 
 def create 
 respond_to do | format | 
 format.html {super} 
 format.json {
 warden.authenticate！（：scope => resource_name，：recall =>＃{controller_path} #failure）
 render：json => {：success => true} 
} 
 end 
 end 
 
 def destroy 
 respond_to do | format | 
 format.html {super} 
 format.json {
 Devise.sign_out_all_scopes？ sign_out：sign_out（resource_name）
 render：json => {} 
} 
 end 
 end 
 
 def failure 
 render：json => {：success => false，：errors => [登录失败]} 
结束
结束
  

但是当身份验证失败时，失败不会返回json失败。我有一个自定义失败的设计。如果我删除redirect_url或完全删除客户故障，则验证将返回一个具有失败消息的json。我的自定义失败如下：

  class CustomFailure< Devise :: FailureApp 
 def redirect_url 
 #return super除非[：worker，：雇主，用户] .include？（scope）#make具体到范围
'/'
 end 
 
＃你需要覆盖响应以消除召回
 def response 
如果http_auth？ 
 http_auth 
 else 
重定向
结束
结束
  

end

无论如何保持重定向，如果它的一个html请求，并返回一个json与失败msg如果它的一个json请求？

谢谢！

解决方案

您必须告诉监护人才能使用该自定义失败。 p>

  def failure 
 respond_to do | format | 
 format.html {super} 
 format.json do 
 warden.custom_failure！ 
 render：json => {：success => false，：errors => [登录失败]} 
结束
结束
结束
  

I have managed to setup json authentication. I implemented the following code:

class Users:: SessionsController < Devise::SessionsController
  def create
    respond_to do |format|  
      format.html { super }  
      format.json {  
        warden.authenticate!(:scope => resource_name, :recall => "#{controller_path}#failure")  
        render :json => {:success => true}  
      }
    end  
  end

  def destroy
    respond_to do |format|
      format.html {super}
      format.json {  
        Devise.sign_out_all_scopes ? sign_out : sign_out(resource_name)
        render :json => {}
      }
    end
  end

  def failure
    render :json => {:success => false, :errors => ["Login Failed"]}
  end
end

This works fine, but when authentication fails, the failure doesnt return the json failure. I have a custom failure for devise. If I remove the redirect_url or remove the customer failure completely, then the authentication returns a json with the failure message. My custom failure is as follows:

class CustomFailure < Devise::FailureApp
  def redirect_url
    #return super unless [:worker, :employer, :user].include?(scope) #make it specific to a scope
     '/'
  end

  # You need to override respond to eliminate recall
  def respond
    if http_auth?
      http_auth
  else
    redirect
  end
end

end

Anyway to keep the redirect if its an html request, and return a json with a failure msg if its a json request?

Thanks!

解决方案

You have to tell warden to use that custom failure.

def failure
  respond_to do |format|
    format.html {super}
    format.json do
      warden.custom_failure!
      render :json => {:success => false, :errors => ["Login Failed"]}
    end
  end
end
