POST方法接收服務器中重複

Question

我發送一個POST請求到服務器，但他們收到它重複相同的日期，甚至時間。這是我的代碼：

-(void) getTerms{ 
    dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), ^{ 

     User *mUser = [[User alloc]init]; 
     NSString *appFile1 = [self getUserFile]; 
     mUser = [NSKeyedUnarchiver unarchiveObjectWithFile:appFile1]; 
     NSString *post = [NSString stringWithFormat:@"Method=GetFAQ&CustomerID=%@",mUser.customerID]; 
     NSData *postData = [post dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:YES]; 
     NSString *postLength = [NSString stringWithFormat:@"%lu", (unsigned long)[post length]]; 

     NSMutableURLRequest *request = [[NSMutableURLRequest alloc] initWithURL:[NSURL URLWithString:[ServerName serverName]]]; 


     [request setHTTPMethod:@"POST"]; 
     [request setValue:postLength forHTTPHeaderField:@"Content-Length"]; 
     [request setHTTPBody:postData]; 

     NSURLConnection *theConnection = [NSURLConnection connectionWithRequest:request delegate:self]; 
     dispatch_async(dispatch_get_main_queue(), ^{ 
      [SVProgressHUD dismiss]; 
      if(theConnection){ 

       // other codes 

      } 

     }); 

    }); 

} 

我只是想知道我的代碼有什麼問題？在此先感謝

這是我如何解決了這個問題：

-(void) getCredit{ 
    dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), ^{ 

     NSString *post = [NSString stringWithFormat:@"Method=%@",mMethod]; 
     NSMutableURLRequest *request = [ServerName postToServer:post]; 

     dispatch_async(dispatch_get_main_queue(), ^{     
      NSURLResponse *requestResponse; 
      NSData *requestHandler = [NSURLConnection sendSynchronousRequest:request returningResponse:&requestResponse error:nil]; 

      NSString *jsonString = [[NSString alloc] initWithBytes:[requestHandler bytes] length:[requestHandler length] encoding:NSUTF8StringEncoding]; 

      NSDictionary *res = [NSJSONSerialization JSONObjectWithData:[jsonString dataUsingEncoding:NSUTF8StringEncoding] options:0 error:nil]; 
      NSDictionary *res1 = [res objectForKey:@"ServerResponse"]; 
     }); 
    }); 
}
