问题描述
我尝试通过在Blackberry中发送http请求来接收响应.它正确打开了Http连接器.但是它无法收到响应.下面提到了我用来接收响应的代码.
I try to receive a response from sending a http request in blackberry. It correctly open the Http Connector. But It can''t receive the response. The code I used yo recieve the response is mentioned below.
String url="https://www.google.lk/";
HttpConnection con = null;
InputStream is = null;
try {
con = (HttpConnection) Connector.open(url);
int responseCode = con.getResponseCode();
Dialog.alert(String.valueOf(responseCode ));
}
catch(Exception e)
{
Dialog.alert(e.getMessage());
}
该代码未如预期的那样显示警告.在Blackberry Simulator上运行应用程序时,也不会发生任何异常.上面的代码有任何错误吗?
The code is not shown a alert as expected in the code. And also any exception is not occurred while running the application on Blackberry simulator. Is any error in above code?
