iOS上的Twitter状态/ update_with_media返回500错误
有没有人使用新的Twitterfunction，状态/ update_with_media？
我试图用它来上传照片，并返回内部服务器错误。
我的要求如下：

任何人都可以帮助我发现什么是错的？
提前致谢！
我已经解决了这个问题，但是我真的不知道根本原因在哪里。
那么，所做的是以下列方式更改代码：
- (NSString *) _uploadImage:(UIImage *)image requestType:(MGTwitterRequestType)requestType responseType:(MGTwitterResponseType)responseType { NSString *boundary = @"----------------------------991990ee82f7"; NSURL *finalURL = [NSURL URLWithString:@"http://upload.twitter.com/1/statuses/update_with_media.json"]; if (!finalURL) { return nil; } OAMutableURLRequest *theRequest = [[[OAMutableURLRequest alloc] initWithURL:finalURL consumer:self.consumer token:_accessToken realm: nil signatureProvider:nil] autorelease]; [theRequest setHTTPMethod:@"POST"]; [theRequest setHTTPShouldHandleCookies:NO]; // Set headers for client information, for tracking purposes at Twitter. [theRequest setValue:_clientName forHTTPHeaderField:@"X-Twitter-Client"]; [theRequest setValue:_clientVersion forHTTPHeaderField:@"X-Twitter-Client-Version"]; [theRequest setValue:_clientURL forHTTPHeaderField:@"X-Twitter-Client-URL"]; NSString *contentType = [NSString stringWithFormat:@"multipart/form-data; boundary=%@", boundary]; [theRequest setValue:contentType forHTTPHeaderField:@"content-type"]; NSMutableData *body = [NSMutableData dataWithLength:0]; [body appendData:[[NSString stringWithFormat:@"--%@\r\n", boundary] dataUsingEncoding:NSUTF8StringEncoding]]; [body appendData:[[NSString stringWithString:@"Content-Disposition: form-data; name=\"media_data[]\"; filename=\"1.png\"\r\n"] dataUsingEncoding:NSUTF8StringEncoding]]; [body appendData:[[NSString stringWithString:@"Content-Type: application/octet-stream\r\n"] dataUsingEncoding:NSUTF8StringEncoding]]; [body appendData:[[NSString stringWithString:@"\r\n"] dataUsingEncoding:NSUTF8StringEncoding]]; [body appendData:[[NSString stringWithString:[UIImageJPEGRepresentation(image, 1.0) base64EncodingWithLineLength:0]] dataUsingEncoding:NSUTF8StringEncoding]]; [body appendData:[[NSString stringWithFormat:@"\r\n--%@\r\n", boundary] dataUsingEncoding:NSUTF8StringEncoding]]; [body appendData:[[NSString stringWithString:@"Content-Disposition: form-data; name=\"status\"\r\n"] dataUsingEncoding:NSUTF8StringEncoding]]; [body appendData:[[NSString stringWithString:@"\r\n"] dataUsingEncoding:NSUTF8StringEncoding]]; [body appendData:[[NSString stringWithString:@"Honeymoon uploads image\r\n"] dataUsingEncoding:NSUTF8StringEncoding]]; [body appendData:[[NSString stringWithFormat:@"--%@--\r\n", boundary] dataUsingEncoding:NSUTF8StringEncoding]]; // -------------------------------------------------------------------------------- // modificaiton from the base clase // our version "prepares" the oauth url request // -------------------------------------------------------------------------------- [theRequest prepare]; [theRequest setHTTPBody:body]; // Create a connection using this request, with the default timeout and caching policy, // and appropriate Twitter request and response types for parsing and error reporting. MGTwitterHTTPURLConnection *connection; connection = [[MGTwitterHTTPURLConnection alloc] initWithRequest:theRequest delegate:self requestType:requestType responseType:responseType]; if (!connection) { return nil; } else { [_connections setObject:connection forKey:[connection identifier]]; [connection release]; } return [connection identifier]; }
与以前的代码有3个不同之处：
1.不同的数据顺序，意味着首先填充图像数据，然后是状态数据
2.使用media_data []键代替media []
3.准备好后调用请求集http请求体
希望这对别人有帮助。
