我有以下用于将数据发布到 Web 服务器的代码，但它给了我空响应，我有多个数据，它们是：-
date,
rig,
driller,
offsider-1,
offsider-2,
shift
,
project,
supervisoremail,
geologistemail,
comments,
plants[0][name-id],
plants[0][start-usage],
plants[0][end-usage],
consumables[0][category],
consumables[0][name-id],
consumables[0][used],
consumables[0][code],
consumables[0][description],
我必须发布这些数据，并且我使用此代码进行发布，但它对我不起作用。请帮帮我。
NSURL *url=[NSURL URLWithString:@"http://www.mydor.com.au/staff/dor/idorInsert"];
NSString *post =[[NSString alloc]initWithFormat:@"date=15/08/2012&rig=53&driller=207&offsider-1=131&offsider- 2=236&shift=day&project=24&supervisoremail=24&geologistemail=24&comments=&plants[0][name- id]=286&plants[0][start-usage]=1.0&plants[0][end-usage]=0.0"];
NSLog(post);
NSData *postData = [post dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:YES];
NSString *postLength = [NSString stringWithFormat:@"%d", [postData length]];
NSMutableURLRequest *request = [[[NSMutableURLRequest alloc] init] autorelease];
[request setURL:url];
[request setHTTPMethod:@"POST"];
[request setValue:postLength forHTTPHeaderField:@"Content-Length"];
[request setValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"Content-Type"];
[request setHTTPBody:postData];
[NSURLRequest setAllowsAnyHTTPSCertificate:YES forHost:[url host]];
NSError *error;
NSURLResponse *response;
NSData *urlData=[NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&error];
NSLog(@"here u re");
NSString *data=[[NSString alloc]initWithData:urlData encoding:NSUTF8StringEncoding];
NSLog(@"here also called");
NSLog(@"%@",data)
