HttpServlet.doOptions介绍

[英]Called by the server (via the service method) to allow a servlet to handle a OPTIONS request. The OPTIONS request determines which HTTP methods the server supports and returns an appropriate header. For example, if a servlet overrides doGet, this method returns the following header:

Allow: GET, HEAD, TRACE, OPTIONS

There's no need to override this method unless the servlet implements new HTTP methods, beyond those implemented by HTTP 1.1.
[中]由服务器调用（通过service方法），以允许servlet处理选项请求。OPTIONS请求确定服务器支持哪些HTTP方法，并返回适当的头。例如，如果servlet重写doGet，此方法将返回以下标头：
Allow: GET, HEAD, TRACE, OPTIONS
除非servlet实现了HTTP 1.1以外的新HTTP方法，否则不需要重写此方法。
