如何通过 twitter api 发布推文？

Question

我已将 twitter api 集成到我的应用程序中。在我的应用程序中，我通过使用 oauth 库获得了 oauth_token 和 oauth_secre_key 。现在我想发布一条新推文。我如何发送带有授权标头的 http 请求。我的问题是我有一个从 twitter api 发送消息的网址，即：-https://api.twitter.com/1/statuses/update.json?status=Maybe%20he%27ll%20finally%20find%20his% 20keys.%20%23peterfalk&trim_user=true&include_entities=true 但是当我打开浏览器时我收到此错误：-

{“错误”：“无法验证您的身份。”，“请求”：“/1/statuses/update.json?status=Maybe%20he%27ll%20finally%20find%20his%20keys.%20%23peterfalk& ;trim_user=true&include_entities=true"}

修复此错误的方法是什么？如何在我的请求中添加授权标头？

预先感谢...

我收到此错误是因为我没有以正确的格式设置参数。现在我使用这段代码并且工作正常。

NSString *trimmedText=[NSString stringWithFormat:@"%@",txt_comment.text];

NSURL *url=[NSURL URLWithString: @"https://api.twitter.com/1/statuses/update.xml"];
NSMutableDictionary *params = [NSMutableDictionary dictionaryWithCapacity:0];
[params setObject:trimmedText forKey:@"status"];
NSString *body = [self _queryStringWithBase:nil parameters:params prefixed:NO];

NSData* requestData = [body dataUsingEncoding: NSUTF8StringEncoding];


OAMutableURLRequest *request = [[[OAMutableURLRequest alloc] initWithURL:url consumer: appDelegate.consumer token: appDelegate.accessToken realm: nil signatureProvider: nil] autorelease];  

[request setHTTPMethod:@"POST"];
[request setHTTPBody:requestData];
OADataFetcher *fetcher = [[OADataFetcher alloc] init];

[fetcher fetchDataWithRequest:request
                     delegate:self
            didFinishSelector:@selector(accessTokenTicket_post:didFinishWithData:)
              didFailSelector:@selector(accessTokenTicket:didFailWithError:)];
