Answer 1

package com.demo;
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
 
import javax.xml.bind.DatatypeConverter;
 
import org.apache.http.HttpResponse;
import org.apache.http.client.methods.HttpGet;
import org.apache.http.impl.client.DefaultHttpClient;
public class restTest {
   public static voidmain(String[] args) {
       try {
           DefaultHttpClient Client = newDefaultHttpClient();
 
           HttpGet httpGet = newHttpGet("你的地址");
           String encoding =DatatypeConverter.printBase64Binary("admin:admin".getBytes("UTF-8"));
           
          httpGet.setHeader("Authorization", "Basic " +encoding);
 
           HttpResponse response = Client.execute(httpGet);
 
           System.out.println("response =" + response);
 
           BufferedReader breader = newBufferedReader(new InputStreamReader(response.getEntity().getContent()));
           StringBuilder responseString = newStringBuilder();
           String line = "";
           while ((line = breader.readLine()) !=null) {
               responseString.append(line);
           }
           breader.close();
           String repsonseStr =responseString.toString();
 
           System.out.println("repsonseStr =" + repsonseStr);
 
       } catch (IOException e) {
           e.printStackTrace();
       }
 
   }
}
