public class NetworkRequestDemo extends AsyncTask<Void, Void, Void> {
    
    @Override
    protected Void doInBackground(Void... voids) {
        HttpURLConnection urlConnection = null;
        BufferedReader reader = null;
        String result = null;
        
        try {
            URL url = new URL("http://www.example.com/api/data");
            urlConnection = (HttpURLConnection) url.openConnection();
            urlConnection.setRequestMethod("GET");
            urlConnection.connect();
            
            InputStream inputStream = urlConnection.getInputStream();
            reader = new BufferedReader(new InputStreamReader(inputStream));
            StringBuilder buffer = new StringBuilder();
            String line;
            while ((line = reader.readLine()) != null) {
                buffer.append(line).append("n");
            }
            result = buffer.toString();
        } catch (IOException e) {
            e.printStackTrace();
        } finally {
            if (urlConnection != null) {
                urlConnection.disconnect();
            }
            if (reader != null) {
                try {
                    reader.close();
                } catch (IOException e) {
                    e.printStackTrace();
                }
            }
        }
        
        if (result != null) {
            Log.d("NetworkRequestDemo", "Result: " + result);
        }
        
        return null;
    }
}

使用方法如下：

NetworkRequestDemo networkRequestDemo = new NetworkRequestDemo();
networkRequestDemo.execute();

这里是一个简单的 Android 网络请求的示例代码，使用 OkHttp 库发送 GET 请求获取数据：

import okhttp3.OkHttpClient;
import okhttp3.Request;
import okhttp3.Response;

public class NetworkRequestDemo {

    public static void main(String[] args) {
        OkHttpClient client = new OkHttpClient();

        Request request = new Request.Builder()
                .url("https://jsonplaceholder.typicode.com/posts/1")
                .build();

        try {
            Response response = client.newCall(request).execute();
            if (response.isSuccessful()) {
                String responseData = response.body().string();
                System.out.println(responseData);
            } else {
                System.out.println("请求失败: " + response.code());
            }
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

这段代码发送一个 GET 请求到 JSONPlaceholder 的测试 API，获取 ID 为 1 的帖子的数据，并将响应打印输出。请注意需要在 Android 项目中添加 OkHttp 的依赖。
