Java Can'；无法从http响应获取设置Cookie头

我正在开发一个小型web内容刮板。代码的一部分是发送http请求并从响应头获取cookie，以便可以在后续请求中进行设置。 获取cookies的代码如下所示：

    HttpClient client = HttpClientBuilder.create().build();
    HttpGet request = new HttpGet(url);

    request.setHeader("Accept", "text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8");

    request.setHeader("Accept-Encoding","gzip,deflate,sdch");

    if(cookie!=null)
    {
      request.setHeader("Cookie", cookie);
    }
         
    request.setHeader("Accept-Language","en-US,en;q=0.8,zh-CN;q=0.6");    
    request.setHeader("Cache-Control", "max-age=0");
    request.setHeader("Connetion", "keep-alive");
    request.setHeader("Host", "www.booking.com");
    request.setHeader("User-Agent", "Mozilla/5.0 (Windows NT 6.1; WOW64) 
           AppleWebKit/537.36 (KHTML, like Gecko) 
           Chrome/32.0.1700.76 Safari/537.36");
    
    try {

        HttpResponse response = client.execute(request);
        int statusCode = response.getStatusLine().getStatusCode();
        System.out.println(statusCode);
        //get all headers       
        Header[] headers = response.getAllHeaders();
        for (Header header : headers) {
            System.out.println("Key : " + header.getName() 
                  + " ,Value : " + header.getValue());
        }
     
    

        System.out.println("----------------------------------------------------------");
        
    } catch (HttpException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }

然而，当我将这个小程序上传到我的服务器并运行它时，结果是：

Set Cookie头消失了，我对同一站点内其他内容页面的后续请求（应该由我请求的第一个页面中的

javascript

加载）都返回了400个错误，我猜这是因为Cookie丢失了。 我不知道为什么，我知道我的电脑和服务器之间的区别是：

我的电脑运行的是Windows 7，实际上有一个Chrome浏览器，而服务器运行的是Linux，没有任何实际的浏览器

ip地址不同。 除了这些，我还想不出其他的

如有任何解决此问题的建议，我们将不胜感激。谢谢。

请使用实际发送的HTTP请求更新您的问题。我认为你想要发送的和实际发送的有一些区别。您可以使用诸如ngrep或fiddler之类的工具捕获请求。@Majid L因为我使用的是云服务器，所以无法获取服务器发出的“实际”HTTP请求。fiddler将只获取虚拟服务器发送的请求，而请求正是我在问题中包含的内容。UserName假设不是我，而是@npcode:）
