HttpClient登录百度无法成功，求解决，问题何在？
模拟登录百度，但始终登录失败

登录百度：
public static void loginWeb(){

user.setId("kexin_bo");
user.setPwd("*******");
HttpManager.getHttpManager().doGet(BaiduConstants.WEB_LOGIN_PAGE, null);
String tokenPage = HttpManager.getHttpManager().doGet(BaiduConstants.WEB_LOGIN_TOKEN_PAGE, null);
String token = BaiduUtils.regex(tokenPage, "(?<=(login_token='))[^']+");
String loginResultPage = HttpManager.getHttpManager().doPost(BaiduConstants.WEB_LOGIN_POST_PAGE, BaiduUtils.getWebLoginForm(user, token));
String loginResult = BaiduUtils.regex(loginResultPage, "(?<=(jump.html\\?error=))\\d+");
boolean isLoginSuccess = false;
if("0".equals(loginResult)){
isLoginSuccess = true;
System.out.println("登录成功!");
}else if("1".equals(loginResult)){
System.out.println("账号格式错误！");
}else if("2".equals(loginResult)){
System.out.println("账号不存在!");
}else if("4".equals(loginResult)){
System.out.println("密码错误");
}else{
System.out.println("登录失败："+loginResult);
}
System.out.println();
if(!isLoginSuccess){
return;
}
}
输出结果：

Login form get: HTTP/1.1 200 OK
登录失败：119998
无法访问登录后的内容。
这是百度做校验了？浏览器能访问，模拟浏览器httpClient理论上肯定也可以，该如何写？
java?HttpClient?百度
[解决办法]
看看是否需要输入验证码啥的，防火墙是否关闭
[解决办法]
清空cookie，清空缓存试下
[解决办法]
在你使用httpclient来做相关模拟登陆的时候，你最好是把浏览器的js禁用掉，因为，有的时候是通过js来发生改变，但是httpclient不能使用js.所以你禁用js来调试试试

我以前做过一个百度自动登录签到软件（java swing），你可以参考参考：
http://pan.baidu.com/share/link?shareid=251715&uk=2885709842
因为考虑到某些原因，如果登录需要验证码的，程序不能进行，需要在某处添加一行代码（我删掉了一行）。
如果不需要验证码的，当然没问题了。
需要那行代码的可以联系我：hhaosjx@qq.com

楼主，你这个程序都使用了什么jar包吗，我想调试一下但是不知道你用的什么jar

GetMethod get=new GetMethod(url);
NameValuePair name=new NameValuePair("wd","游隼");
post.setRequestBody(new NameValuePair[]{name} );
get.setQueryString(new NameValuePair[]{name});
HttpClient client=new HttpClient();
int m=client.executeMethod(get);
//System.out.println("执行返回代码 "+m);
System.out.println(get.getResponseBodyAsString());
File file=new File("d:\\123.html");
PrintWriter p=new PrintWriter(file);
p.append(get.getResponseBodyAsString());
System.out.println("网页已经生成！！！");
}
}

楼主，没用的，最新的百度不再直接把登陆框加载出来了，而是采用js去加载，除非你把它的js代码研究透了，写个java代码模拟js，才可以得到最终的token和verifycodestring，这个实在是太麻烦了...
[解决办法]
一年多前我就用httpClient登百度，期间百度多次改变其前台代码，每次都要费不少精力去摸索新的登录方法，烦了，不玩了。
