Android网络编程

Scoket

Socket编程客户端

Socket s=new Socket(ip, port);

Socket编程服务端

ServerSocket ss=new ServerSocket(port);
Socket s=ss.accept();

Socket服务端的基本编程架构：

ServerSocket ss=new ServerSocket();
while(true){
  Socket s=ss.accept();
  new Thread(){
    public void run(){
      s.getInputStream()
      s.getOutputStream()
    }
  }.start();
}

HttpGet和HttpPost

Android客户端如何发送HttpGet请求
1、创建HttpClient对象

HttpClient client=new DefaultHttpClient();

2、创建HttpGet请求对象

String uri="http://ip:port/app/path?name=x";
HttpGet get=new HttpGet(uri);

3、调用execute方法执行get请求

HttpResponse resp=client.execute(get);

4、解析获取响应数据包中的内容：

resp.getEntity();

Android客户端如何发送HttpPost请求
1、创建HttpClient

  HttpClient client=new DefaultHttpClient();

2、创建HttpPost请求对象

  String uri="http://xxxxx";
  HttpPost post=new HttpPost(uri);

3、传递参数

  List<NameValuePair> list=new ArrayList<>();
  list.add(new BasicNameValuePair("number", "No.100100"));
  list.add(new BasicNameValuePair("number", "No.100100"));
  list.add(new BasicNameValuePair("number", "No.100100"));
  HttpEntity entity=new UrlEncodedFormEntity(list,"utf-8");
  post.setEntity(entity);

4、设置消息头

post.setHeader(“Content-Type”, “application/x-www-form-urlencoded”);

5、调用execute方法发送请求

HttpResponse resp=client.execute(post);

6、解析获取相应数据包中的内容

resp.getEntity();
