一 ：普通請求，根據設置參數andRequestType爲POST或GET 來確定請求方式
ASIFormDataRequest部分：

[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
NSMutableDictionary *dic=[[NSMutableDictionary alloc] init];
[dic setObject:@"1" forKey:@"newwindow"];

}AFNetworking部分：
用AFNetworking來請求

}

}
