安卓使用HttpURLConnection以get方式请求数据

1、实例化URL对象

URL url = new URL("https://www.baidu.com/s?ie=UTF-8&wd=get");

2、通过URL对象打开链接获取HttpURLConnection的实例化对象

HttpURLConnection conn = (HttpURLConnection) url.openConnection();

3、设置请求方式

conn.setRequestMethod("GET");

4、通过HttpURLConnection对象获取输入流

 InputStream is = conn.getInputStream();

5、将输入流转换成String类型

//把一个inputStream 转换成一个String
public String inputStreamToString(InputStream is) throws Exception{
	ByteArrayOutputStream baos = new ByteArrayOutputStream();
	int len = -1;
	byte[] buffer = new byte[1024]; 
	while((len=is.read(buffer))!=-1){
	    baos.write(buffer, 0, len);
	}
	is.close();
	String content = new String(baos.toByteArray());
	return content;
}


String result = inputStreamToString(is);

或者使用BufferReader类转换

BufferedReader r
