如何在HTTP GET中获取锚点名称? [英] How to get the anchor name in HTTP GET?

问题描述

在Java Web项目中，如何获得(如果可能)URL请求中的"HTTP锚"部分?例如，当请求URL为 http://localhost:8080/servlet/page.htm?param1=value1&param2=value2#section 我希望能够识别 #section 部分.

In a Java web project, how can I get (if possible) the "HTTP anchor" part in a URL request? For example, when the request URL is http://localhost:8080/servlet/page.htm?param1=value1&param2=value2#section I want to be able to recognize the #section part.

public void doGet
(HttpServletRequest request, HttpServletResponse response) 
throws ServletException, IOException 
{
  // ...
  System.out.println("QueryString = " + request.getQueryString());
  // ...
}

上面的示例在#之前的子字符串 中生成子字符串，在这种情况下为: param1 = value1& param2 = value2 .有没有办法提取#符号后 的URL部分?

The example above produces the substring preceeding the #, in this case: param1=value1&param2=value2. Is there a way to extract the part of the URL after the # sign?

如果有什么用，我正在使用Apache Click框架.

If this is of any use, I'm using the Apache Click framework.

推荐答案

我不认为锚点部分已发送到服务器.它仅由浏览器处理.也许您可以使用JavaScript提取它.

I don't think the anchor part is send to the server. It is only processed by the browser. Maybe you can extract it using JavaScript.

根据 RFC 1808 :

请注意，片段标识符(及其前面的#")为不被视为URL的一部分.

Note that the fragment identifier (and the "#" that precedes it) is not considered part of the URL.

var url=window.location;
var anchor=url.hash; //anchor with the # character  
var anchor2=url.hash.substring(1); //anchor without the # character
