一个看似奇怪的OAuthException(A seemingly strange OAuthException)

 我正在学习构建fb应用程序，并且在第一次尝试时，我得到了这个奇怪的OAuthException。 该教程清楚地提到我需要传递redirect_uri，client_secret，client_id和代码（来自app auth阶段）。 但是当流程完成时，我得到的是JSON错误对象，而不是获取访问令牌： 
 
{"error":{"message":"client_secret should not be passed to \/oauth\/access_token\/","type":"OAuthException"}}
 
 编辑：这是我用来建立网址的片段（请原谅第二行过多，请） 
 
url = "https://graph.facebook.com/oauth/access_token/"
url += "?" 
url += urllib.urlencode([('client_id',client_id),
                           ('redirect_uri', redirect_uri),
                           ('client_secret', client_secret),
                           ('code', code)])
 
 变量保存正确的值。（选中> 5次） 

I am learning to build fb apps, and on the very first attempt, I get this strange OAuthException. The tutorial clearly mentions that I need to pass redirect_uri, client_secret, client_id and code(from the app auth phase). But when the flow completes, instead of getting an access token here is the JSON error object I get:
 
{"error":{"message":"client_secret should not be passed to \/oauth\/access_token\/","type":"OAuthException"}}
 
EDIT: this is the snippet I'm using to build the url(pardon the excessive 2nd line, please)
 
url = "https://graph.facebook.com/oauth/access_token/"
url += "?" 
url += urllib.urlencode([('client_id',client_id),
                           ('redirect_uri', redirect_uri),
                           ('client_secret', client_secret),
                           ('code', code)])
 
where the variables hold correct values.(checked > 5 times)
