HttpServletRequest 完成 URL [英] HttpServletRequest to complete URL

问题描述

我有一个 HttpServletRequest 对象.

如何获取导致此调用到达我的 servlet 的完整且准确的 URL?

How do I get the complete and exact URL that caused this call to arrive at my servlet?

或者至少尽可能准确，因为也许有些东西可以重新生成(可能是参数的顺序).

Or at least as accurately as possible, as there are perhaps things that can be regenerated (the order of the parameters, perhaps).

推荐答案

HttpServletRequest 有以下方法:

The HttpServletRequest has the following methods:

• getRequestURL() - 返回查询字符串分隔符 ?
之前的完整 URL 部分
• getQueryString() - 返回查询字符串分隔符 ?
后的完整 URL 部分

• getRequestURL() - returns the part of the full URL before query string separator character ?
• getQueryString() - returns the part of the full URL after query string separator character ?

因此，要获取完整的 URL，只需执行以下操作:

So, to get the full URL, just do:

public static String getFullURL(HttpServletRequest request) {
    StringBuilder requestURL = new StringBuilder(request.getRequestURL().toString());
    String queryString = request.getQueryString();

    if (queryString == null) {
        return requestURL.toString();
    } else {
        return requestURL.append('?').append(queryString).toString();
    }
}
