HttpClient 对 cookie 的处理详解编程语言

public static void main(String[] args) { 
        HttpClient client = new HttpClient(); 
        NameValuePair[] nameValuePairs = { 
                new NameValuePair("username", "aaa"), 
                new NameValuePair("passwd", "123456") 
        }; 
        PostMethod postMethod = new PostMethod("登录url"); 
        postMethod.setRequestBody(nameValuePairs); 
        int stats = 0; 
        try { 
            stats = client.executeMethod(postMethod); 
        } catch (HttpException e) { 
            e.printStackTrace(); 
        } catch (IOException e) { 
            e.printStackTrace(); 
        } 
        postMethod.releaseConnection();//这里最好把之前的资源放掉 
        CookieSpec cookiespec = CookiePolicy.getDefaultSpec(); 
        Cookie[] cookies = cookiespec.match("域名", 80/*端口*/, "/" , false , client.getState().getCookies()); 
        for (Cookie cookie : cookies) { 
            System.out.println(cookie.getName() + "##" + cookie.getValue()); 
        } 
          
        HttpMethod method = null; 
        String encode = "utf-8";//页面编码,按访问页面改动 
        String referer = "http://域名";//http://www.163.com 
        method = new GetMethod("url2");//后续操作 
        method.getParams().setParameter("http.useragent","Mozilla/4.0 (compatible; MSIE 5.5; Windows 98)"); 
        method.setRequestHeader("Referer", referer); 
  
        client.getParams().setContentCharset(encode); 
        client.getParams().setSoTimeout(300000); 
        client.getParams().setParameter(HttpMethodParams.RETRY_HANDLER, new DefaultHttpMethodRetryHandler(10, true)); 
    
        try { 
            stats = client.executeMethod(method); 
        } catch (HttpException e) { 
            e.printStackTrace(); 
        } catch (IOException e) { 
            e.printStackTrace(); 
        } 
        if (stats == HttpStatus.SC_OK) { 
            System.out.println("提交成功!"); 
              
        } 
    }
