本文详细介绍了在Android中如何使用原生的HttpURLConnection进行GET和POST请求，包括设置连接和读取超时时间、发送请求参数以及接收响应数据的完整过程。同时提供了OkHttp3和Retrofit2的使用链接，为开发者提供全面的网络请求解决方案。

Android主要就是HTTP请求

主要使用原生的HttpURLConnection或者开源框架okhttp3和retrofit2

HttpURLConnection示例get请求

new Thread(new Runnable() {
            @Override
            public void run() {
                HttpURLConnection connection = null;
                BufferedReader reader=null;
                try{
                    URL url=new URL("https://www.baidu.com");
                    connection= (HttpURLConnection) url.openConnection();
                    connection.setRequestMethod("GET");
                    connection.setConnectTimeout(8000);
                    connection.setReadTimeout(8000);
                    InputStream in=connection.getInputStream();
                    reader=new BufferedReader(new InputStreamReader(in));
                    StringBuilder builder=new StringBuilder();
                    String line;
                    while((line=reader.readLine())!=null){
                        builder.append(line);
                    }
                    Log.i(TAG, "onCreate: "+builder.toString());
                } catch (MalformedURLException e) {
                    e.printStackTrace();
                } catch (ProtocolException e) {
                    e.printStackTrace();
                } catch (IOException e) {
                    e.printStackTrace();
                }finally {
                    try {
                        reader.close();
                        connection.disconnect();
                    } catch (IOException e) {
                        e.printStackTrace();
                    }

                }
            }
        }).start();

HttpURLConnection示例post请求

        new Thread(new Runnable() {
            @Override
            public void run() {
                HttpURLConnection connection = null;
                BufferedReader reader=null;
                try{
                    URL url=new URL("https://www.baidu.com");
                    connection= (HttpURLConnection) url.openConnection();
                    connection.setRequestMethod("POST");
                    connection.setConnectTimeout(8000);
                    connection.setReadTimeout(8000);
                    connection.setDoOutput(true);
                    OutputStream outputStream=connection.getOutputStream();
                    String s="telephone=17131454890";
                    byte[] b=s.getBytes();
                    outputStream.write(b);
                    outputStream.close();
                    InputStream in=connection.getInputStream();
                    reader=new BufferedReader(new InputStreamReader(in));
                    StringBuilder builder=new StringBuilder();
                    String line;
                    while((line=reader.readLine())!=null){
                        builder.append(line);
                    }
                    Log.i(TAG, "onCreate: "+builder.toString());
                    in.close();
                } catch (MalformedURLException e) {
                    e.printStackTrace();
                } catch (ProtocolException e) {
                    e.printStackTrace();
                } catch (IOException e) {
                    e.printStackTrace();
                }finally {
                    try {
                        reader.close();
                    } catch (IOException e) {
                        e.printStackTrace();
                    }
                    connection.disconnect();
                }
            }
        }).start();
