读取 HTTP GET 请求的正文

URL url = new URL("http://example.com");
HttpURLConnection connection = (HttpURLConnection) url.openConnection();

try {
    BufferedReader br = new BufferedReader(new InputStreamReader(connection.getInputStream()));

    // use a string builder to bufferize the response body
    // read from the input strea.
    StringBuilder sb = new StringBuilder();
    String line;
    while ((line = br.readLine()) != null) {
        sb.append(line).append('\n');
    }

    // use the string builder directly,
    // or convert it into a String
    String body = sb.toString();

    Log.d("HTTP-GET", body);

} finally {
    connection.disconnect();
}

请注意，上述示例中未处理异常。
