Rails ActiveResource检测HTTP 206响应代码

Question

如何检测到活动资源find()调用返回的HTTP 206而不是典型的HTTP 200？

我知道ActiveResource会为HTTP 3xx-5xx响应代码抛出各种异常，但是如何找出您收到的200级响应代码呢？

请参阅Active Resource responses, how to get them了解如何获取线程的最后响应。然后，您可以根据需要测试响应代码：

class MyConn < ActiveResource::Connection 
    def handle_response(resp) 
    # Store in thread (thanks fivell for the tip). 
    # Use a symbol to avoid generating multiple string instances. 
    Thread.current[:active_resource_connection_last_response] = resp 
    super 
    end 
    # this is only a convenience method. You can access this directly from the current thread. 
    def last_resp 
    Thread.current[:active_resource_connection_last_response] 
    end 
end 

class MyResource < ActiveResource::Base 
    class << self 
    attr_writer :connection 
    end 
end 

myconn = MyConn.new MyResource.connection.site 
MyResource.connection = myconn # replace with our enhanced version 
object = MyResource.find(id) 
response_code = MyResource.last_resp.code
