Hudson.getRootUrlFromRequest介绍

[英]Gets the absolute URL of Hudson top page, such as "http://localhost/hudson/".

Unlike #getRootUrl(), which uses the manually configured value, this one uses the current request to reconstruct the URL. The benefit is that this is immune to the configuration mistake (users often fail to set the root URL correctly, especially when a migration is involved), but the downside is that unless you are processing a request, this method doesn't work.
[中]获取Hudson首页的绝对URL，例如“http://localhost/hudson/".
与使用手动配置的值的#getRootUrl（）不同，此函数使用当前请求来重建URL。这样做的好处是不受配置错误的影响（用户通常无法正确设置根URL，尤其是在涉及迁移时），但缺点是，除非您正在处理请求，否则此方法不起作用。

  else {
    rootUrl = hudson.getRootUrlFromRequest();
