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,当我尝试发布时,我收到以下错误

{"meta":{"status":401,"msg":"Not Authorized"},"response":[]}

我正在使用OAuthConsumeriOS 客户端,如果从MGTwitterEngine.

这是我尝试过的。

我在这里犯了什么错误?为什么我收到这个错误?我是否正确遵循了这些步骤?

请 XXX 出您的 consumer_key 和 consumer_secret 以避免不必要的使用。代码方面,您可能想在这里寻找一些东西。

  1. 您是否能够使用诸如“ http://api.tumblr.com/v2/user/info ”之类的 oauth 'GET' 请求?如果您可以收到成功的“GET”请求,那么您的访问令牌是有效的,您可以查看如何发送您的帖子参数。

  2. 确保您将参数作为 HTTP 正文和签名参数传递。库可能提供了正确的参数排序。

    NSString *postbody = @"body=myBodyText&type=text";

    [oRequest setHTTPBody:[postbody dataUsingEncoding:NSUTF8StringEncoding allowLossyConversion:TRUE]];
