使用HttpClient模拟登录 博客园

最近在做Android版的博客园客户端,在考虑添加入登录功能,以实现获取更多的信息。

现在测试使用HttpClient进行模拟登陆。

登录页面:http://passport.cnblogs.com/login.aspx

登录结果页面:http://home.cnblogs.com/ 、 http://www.cnblogs.com/ 、……

登录的时候要求提供用户名和密码,属性分别是tbUserName 和 tbPassword;如图所示:

登录成功,转到下一个页面时,需要提供Cookies,还可以设置UA等属性:

具体代码:

 1 package com.arlen.login;
 2 
 3 import org.apache.commons.httpclient.Cookie;
 4 import org.apache.commons.httpclient.HttpClient;
 5 import org.apache.commons.httpclient.NameValuePair;
 6 import org.apache.commons.httpclient.cookie.CookiePolicy;
 7 import org.apache.commons.httpclient.methods.GetMethod;
 8 import org.apache.commons.httpclient.methods.PostMethod;
 9 import org.apache.commons.httpclient.params.HttpMethodParams;
10 
11 public class ImitateLogin {
12 
13     public static void main(String[] args) {
14         String userName = "username";
15         String password = "password"
16         String loginUrl = "http://passport.cnblogs.com/login.aspx";
17         String dataUrl = "http://home.cnblogs.com/";
18         HttpClientLogin(userName, password, loginUrl, dataUrl);
19     }
20 
21     private static void HttpClientLogin(String userName, String password,
22             String loginUrl, String dataUrl) {
23         HttpClient httpClient = new HttpClient();
24         httpClient.getParams().setParameter(
25                 HttpMethodParams.HTTP_CONTENT_CHARSET, "utf-8");
26         PostMethod postMethod = new PostMethod(loginUrl);
27 
28         NameValuePair[] postData = { new NameValuePair("tbUserName", userName),
29                 new NameValuePair("tbPassword", password) };
30         postMethod.setRequestBody(postData);
31 
32         try {
33 
34             httpClient.getParams().setCookiePolicy(
35                     CookiePolicy.BROWSER_COMPATIBILITY);
36             httpClient.executeMethod(postMethod);
37             Cookie[] cookies = httpClient.getState().getCookies();
38             StringBuffer stringBuffer = new StringBuffer();
39             for (Cookie c : cookies) {
40                 stringBuffer.append(c.toString() + ";");
41             }
42 
43             GetMethod getMethod = new GetMethod(dataUrl);
44             getMethod.setRequestHeader("Cookie", stringBuffer.toString());
45             postMethod.setRequestHeader("Host", "passport.cnblogs.com");
46             postMethod.setRequestHeader("Referer", "http://home.cnblogs.com/");
47             postMethod.setRequestHeader("User-Agent", "AndroidCnblogs");
48             httpClient.executeMethod(getMethod);
49 
50             String result = getMethod.getResponseBodyAsString();
51             System.out.println(result);
52 
53         } catch (Exception e) {
54             e.printStackTrace();
55         }
56     }
57 
58 }
