哪位大神帮忙指点一下猎聘网模拟登陆的问题

Question

当前的form action为http://www.liepin.com/webUser/login4c.json，必要的参数都填写了，但是无法成功登陆。
我的代码如下:
HttpClient httpClient = new HttpClient();
httpClient.getHostConfiguration().setHost("211.151.18.66", 80);
PostMethod postMethod = new PostMethod("http://www.liepin.com/webUser/login4c.json");
postMethod.setRequestBody(new NameValuePair[]{
new NameValuePair("layer_from","wwwindex_rightbox_new"),
new NameValuePair("user_login","XXX"),
new NameValuePair("user_pwd", "XXX")
});
System.out.println(httpClient.executeMethod(postMethod));
System.out.println(postMethod.getResponseBodyAsString());

用fiddler调试下，重点看cookie、referer、useragent
