android 用HttpURLConnection读网络

网络上很多关于httpUrlconnection的例子，

void getInput(){ try { URL url = new URL("http://www.google.cn/"); HttpURLConnection conn = (HttpURLConnection) url.openConnection(); conn.setDoInput(true); conn.setConnectTimeout(10000); conn.setRequestMethod("GET"); conn.setRequestProperty("accept", "*/*"); String location = conn.getRequestProperty("location"); int resCode = conn.getResponseCode(); conn.connect(); InputStream stream = conn.getInputStream(); byte[] data=new byte[102400]; int length=stream.read(data); String str=new String(data,0,length); conn.disconnect(); System.out.println(str); stream.close(); } catch(Exception ee) { System.out.print("ee:"+ee.getMessage()); } }

只是要注意的是配置一个权限，AndroidManifest.xml 中应该加入如下节点。
</activity>
</application>
<uses-permission android:name="android.permission.INTERNET"></uses-permission>
</manifest>
可以把AndroidManifest.xml open with manifest editor 来编辑在permissions中add uses-permission，然后再在name中选择android.permission.INTERNET，然后save就ok了。
