我正在尝试将“tumblr”集成到我的应用程序中。我能够成功获取访问令牌。但是，当我尝试发帖时，出现以下错误
{"meta":{"status":401,"msg":"Not Authorized"},"response":[]}
我正在使用OAuthConsumeriOS 客户端，我已经从中提取了MGTwitterEngine.
这是我尝试过的。

我在这里犯了什么错误？为什么我会收到这个错误？我是否正确遵循了步骤？
请XXX取出您的consumer_key和consumer_secret，以避免它们被不必要的使用。
就代码而言，您可能需要在这里查找一些内容。
您是否可以使用 oauth 'GET' 请求，例如“http://api.tumblr.com/v2/user/info http://api.tumblr.com/v2/user/info“？
如果您可以成功收到“GET”请求，则您的访问令牌有效，您可以查看如何发送帖子参数。
-
确保您将参数作为 HTTP 正文以及签名参数传递。库可能提供正确的参数排序。
NSString *postbody = @"body=myBodyText&type=text";
[oRequest setHTTPBody:[postbody dataUsingEncoding:NSUTF8StringEncodingallowLossyConversion:TRUE]];
