Question

您好我使用HttpClient获取Cookie但我找不到任何Cookie。我的代码如下：

public class LoginTab {

    private Cookie[] cookies;
    HttpClient httpClient;
    HttpState httpState;
    HashMap postData;

    public LoginTab() {
        httpClient = new HttpClient();
        httpState = new HttpState();
        httpClient.getHttpConnectionManager().
                getParams().setConnectionTimeout(300000);
        httpClient.setState(httpState);
        // RFC 2101 cookie management spec is used per default
        // to parse, validate, format & match cookies
        httpClient.getParams().setCookiePolicy(CookiePolicy.RFC_2109);
        postData= new HashMap();
    }

    public String getMethod(String url) {
        GetMethod getMethod = new GetMethod(url);
          String pageSoure="";
        try{
        httpClient.executeMethod(getMethod);
         pageSoure=getMethod.getResponseBodyAsString();
        extractUsefulPostData(pageSoure, postData);
        getMethod.releaseConnection();
        }catch(Exception ex)
        {
            ex.printStackTrace();
        }
        return pageSoure;
    }
    public static void main(String[]arg)
    {
        LoginTab loginTab= new LoginTab();
        System.out.println(loginTab.getMethod("http://tab.com.au/"));
        Cookie [] cookies=loginTab.httpState.getCookies();
        System.out.println(cookies.length);
        for(int i=0;i<cookies.length;i++)
            System.out.println(cookies[i]);
    }
}

请告诉我，我犯了一个错误。提前致谢

我已尝试使用所有可用的CookiePolicy，并设置“用户代理”内容但未成功。从我看到的java - verbose中，getCookie（）方法中存在一个被困的异常：

org.apache.commons.httpclient.util.DateParseException

从网站收到的cookie（我可以在firefox上用Cookie编辑器看到它）可能对httpclient不利;看看this线程是否存在同样的问题根据我的看法，您需要启用日志记录并检查httpclient在cookie解析时所执行的操作。
