下面的代码使用HTTPPOST将NSData发布到Web服务器。您还需要一些PHP方面的知识。NSString *urlString = @"http://yourserver.com/upload.php";NSString *filename = @"filename";request= [[[NSMutableURLRequest alloc] init] autorelease];[request setURL:[NSURL URLWithString:urlString]];[request setHTTPMethod:@"POST"];NSString *boundary = @"---------------------------14737809831466499882746641449";NSString *contentType = [NSString stringWithFormat:@"multipart/form-data; boundary=%@",boundary];[request addValue:contentType forHTTPHeaderField: @"Content-Type"];NSMutableData *postbody = [NSMutableData data];[postbody appendData:[[NSString stringWithFormat:@"\r\n--%@\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]];[postbody appendData:[[NSString stringWithFormat:@"Content-Disposition: form-data; name=\"userfile\"; filename=\"%@.jpg\"\r\n", filename] dataUsingEncoding:NSUTF8StringEncoding]];[postbody appendData:[[NSString stringWithString:@"Content-Type: application/octet-stream\r\n\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];[postbody appendData:[NSData dataWithData:YOUR_NSDATA_HERE]];[postbody appendData:[[NSString stringWithFormat:@"\r\n--%@--\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]];[request setHTTPBody:postbody];NSData *returnData = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil];returnString = [[NSString alloc] initWithData:returnData encoding:NSUTF8StringEncoding];NSLog(@"%@", returnString);
