ASIHttpRequest NSURL参数问题

两种方式都可以加参数
1.NSURL
  [ NSURL URLWithString : [NSString stringWithFormat:@"http://192.168.1.100:8080/down?method=%@",abcdef] ];


2.ASIFormDataRequest
ASIFormDataRequest *request = [ASIFormDataRequest requestWithURL:url];
[request setPostValue:@"Ben" forKey:@"first_name"];
[request setPostValue:@"Copsey" forKey:@"last_name"];
