Two ways in which Java code simulates HTTP requests

Z here with Baidu Map of the inverse geocoding interface for example,

First way: (Through the java.net package in the JDK)

• Introducing Tool Classes
  

  Import Java.net.URL;
  Import java.net.URLConnection;

• Set URL

  String url = "http://api.map.baidu.com/geocoder/v2/?" +
          "callback=renderreverse&location=40.073357,116.352891&output=json&pois=0&ak=" + mapAk;

• To create an instance from a URL

  URL myurl = null;
  URLConnection httpsconn = null;

  myurl = new URL (URL);
  Httpsconn = (urlconnection) myurl.openconnection ();

• Get the return data by the way to the inflow

  InputStreamReader INSR = null;
  INSR = new InputStreamReader (
          Httpsconn.getinputstream (), "UTF-8");
  BufferedReader br = new BufferedReader (INSR);
  String datastr = Br.readline ();

• Close the input stream

  Insr.close ();

Second approach: (implemented via HttpClient)
