// //post请求中url不带请求参数,请求参数在参数HTTPBody中设置, 需要创建可变的url请求,设置请求方式为post //创建url NSURL *url = [[NSURL alloc] initWithString:@""]; //创建可变的url请求 NSMutableURLRequest *mRequest = [[NSMutableURLRequest alloc] initWithURL:url]; //设置请求方式为POST mRequest.HTTPMethod = @"POST"; //设置请求参数 NSString *sendString = @"type=focus-c”; //HTTPBody为NSData类型, 所以需要将NSString类型转换为NSDate类型 mRequest.HTTPBody = [sendString dataUsingEncoding:NSUTF8StringEncoding]; //发送同步请求 NSData *data = [NSURLConnection sendSynchronousRequest:mRequest returningResponse:nil error:nil]; //将NSData转换为NSString类型 NSString *string = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding]; NSLog(@"%@", string);
