HttpURLConnection的get用法

final String path="路径";
new Thread(){
public void run() {
  try {
    URL url=new URL(path);
    HttpURLConnection connection = (HttpURLConnection) url.openConnection();

//设置连接超时的时长
    connection.setConnectTimeout(5000);

//设置读取超时的时长
    connection.setReadTimeout(5000);

//设置读取方法
    connection.setRequestMethod("GET");
    if(connection.getResponseCode()==200){
    InputStream is=connection.getInputStream();
    ByteArrayOutputStream bos=new ByteArrayOutputStream();
    int len=0;
    byte[] by=new byte[1024];
    while((len=is.read(by))!=-1){
      bos.write(by,0,len);
    }

//读取出的内容
    String json=bos.toString();

//用Gson解析出来
    Gson gson=new Gson();
    Goods goods = gson.fromJson(json, Goods.class);


    List<Deals> deals = goods.deals;

//发送消息
    Message msg=Message.obtain();
    msg.obj=deals;
    handler.sendMessage(msg);
  }
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
};
}.start();
