安卓使用InputStream获取网站内容

try {
    URL url = new URL("http://www.example.com"); // 指定网站的URL
    HttpURLConnection connection = (HttpURLConnection) url.openConnection(); // 建立连接
    connection.setRequestMethod("GET"); // 设置请求方法为GET
    connection.connect(); // 发起连接

    int responseCode = connection.getResponseCode(); // 获取响应码
    if (responseCode == HttpURLConnection.HTTP_OK) { // 判断响应码是否为200
        InputStream inputStream = connection.getInputStream(); // 获取输入流
        BufferedReader reader = new BufferedReader(new InputStreamReader(inputStream));
        StringBuilder content = new StringBuilder();
        String line;
        while ((line = reader.readLine()) != null) {
            content.append(line);
        }
        reader.close();
        inputStream.close();

        String websiteContent = content.toString(); // 获取网站内容
        // 对网站内容进行处理或展示
    } else {
        // 处理响应码不为200的情况
    }
} catch (IOException e) {
    e.printStackTrace();
}
