通过json设计失败身份验证返回html而不是json

Question

我设法设置了json身份验证。我执行下面的代码：

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 => ["Login Failed"]} 
    end 
end 

这工作得很好，但在验证失败，失败犯规返回JSON失败。对于设计我有一个自定义的失败。如果我删除了redirect_url或完全删除了客户失败，那么身份验证将返回带有失败消息的json。我的自定义故障如下：

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 

末

反正保持重定向如果一个HTML请求，并具有故障味精如果JSON请求返回一个JSON？

谢谢！

您必须告诉看守使用该自定义失败。

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
