Client authentication

This example uses HttpClient to execute an HTTP request against a target site that requires user authentication.

 

客户身份验证

 

本实例用HttpClient去执行一个HTTP请求，对方网站是要求用户身份验证。

 

package cn.lake.util;

import org.apache.http.HttpEntity;
import org.apache.http.HttpResponse;
import org.apache.http.auth.AuthScope;
import org.apache.http.auth.UsernamePasswordCredentials;
import org.apache.http.client.methods.HttpGet;
import org.apache.http.impl.client.DefaultHttpClient;

/**
 * A simple example that uses HttpClient to execute an HTTP request against
 * a target site that requires user authentication. 
 */
public class ClientAuthentication {

	public static void main(String[] args) throws Exception {
		DefaultHttpClient httpclient = new DefaultHttpClient();

		httpclient.getCredentialsProvider().setCredentials(new AuthScope("localhost", 443),
				new UsernamePasswordCredentials("username", "password"));

		HttpGet httpget = new HttpGet("https://localhost/protected");

		System.out.println("executing request" + httpget.getRequestLine());
		HttpResponse response = httpclient.execute(httpget);
		HttpEntity entity = response.getEntity();

		System.out.println("----------------------------------------");
		System.out.println(response.getStatusLine());
		if (entity != null) {
			System.out.println("Response content length: " + entity.getContentLength());
		}
		if (entity != null) {
			entity.consumeContent();
		}
	}
}

 

主要是这句代码：

 

httpclient.getCredentialsProvider().setCredentials(new AuthScope("localhost", 443),new UsernamePasswordCredentials("username", "password"));
