在Android的HTTP GET请求 [英] Http get request in Android

问题描述

我需要发送HTTP GET请求帮助。像这样的：

I need help with sending http get request. Like this:

URL connectURL;
connectURL = new URL(address);
HttpURLConnection conn = (HttpURLConnection)connectURL.openConnection(); 
// do some setup
conn.setDoInput(true); 
conn.setDoOutput(true); 
conn.setUseCaches(false); 
conn.setRequestMethod("GET"); 
// connect and flush the request out
conn.connect();
conn.getOutputStream().flush();
// now fetch the results
String response = getResponse(conn);
et.setText(response);

我在网上搜索，但我尝试任何方法中，code。在失败'conn.connect（）; 。任何线索？

推荐答案

如果你想要一些的演示code 然后尝试以下操作：

If you want some demo code then try following:

 URL url = new URL("url.com");
   HttpURLConnection urlConnection = (HttpURLConnection) url.openConnection();
   try {
     InputStream in = new BufferedInputStream(urlConnection.getInputStream());
     readStream(in);
   } finally {
     urlConnection.disconnect();
   }

和这样的：

   HttpURLConnection urlConnection = (HttpURLConnection) url.openConnection();
   try {
     urlConnection.setDoOutput(true);
     urlConnection.setChunkedStreamingMode(0);

     OutputStream out = new BufferedOutputStream(urlConnection.getOutputStream());
     writeStream(out);

     InputStream in = new BufferedInputStream(urlConnection.getInputStream());
     readStream(in);
   } finally {
     urlConnection.disconnect();
   }

希望这有助于。
