고안 문서에서

# config/initializers/devise.rb 

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

Answer 1

,

config.http_authenticatable_on_xhr = TRUE

If http headers should be returned for AJAX requests. True by default. 

의 config.navigational_formats = " / " : HTML : JSON]

==> Navigation configuration 
    Lists the formats that should be treated as navigational. Formats like 
    :html, should redirect to the sign in page when the user does not have 
    access, but formats like :xml or :json, should return 401. 

    If you have any extra navigational formats, like :iphone or :mobile, you 
    should add them to the navigational formats lists. 

    The :"*/*" and "*/*" formats below is required to match Internet 
    Explorer requests.
