本文介绍了一种从HTTP请求中读取响应并转换为字符串的方法。通过使用InputStreamReader和BufferedReader，逐行读取输入流并将内容拼接成字符串。示例展示了如何向“www.baidu.com”发送GET请求，获取输入流并将其转换为字符串。

public static String ResultToString(InputStream inputStream){  
        InputStreamReader inputStreamReader = new InputStreamReader(inputStream);  
        BufferedReader bufferedReader = new BufferedReader(inputStreamReader);  
        StringBuilder result = new StringBuilder();  
        String line = null;  
        try {  
            while((line = bufferedReader.readLine()) != null){  
                result.append(line + "\n");  
            }  
        } catch (IOException e) {  
            e.printStackTrace();  
        } finally {  
            try{  
                inputStreamReader.close();  
                inputStream.close();  
                bufferedReader.close();  
            }catch(IOException e){  
                e.printStackTrace();  
            }  
        }  
        return result.toString();  
    } 
	
	public static void main(String[] args) throws IOException {
		URL url = new URL("http:www.baidu.com") ;
        HttpURLConnection urlConnection = (HttpURLConnection) url.openConnection() ;
        urlConnection.setRequestMethod("GET") ;
        urlConnection.connect() ;
        InputStream inputStream = urlConnection.getInputStream() ;
        String result = ConvertToString(inputStream) ;
        System.out.println(result);
	}
