示例1: checkConditionalRequestHeaders
/**
* Check selected RFC 7232 precondition headers
*
* RFC 7232 envisions a particular model where you send your request to "a
* resource", and for write requests that you can read "the resource" by
* changing the method to GET. When the API receives a GET request, it
* works out even though "the resource" from RFC 7232's perspective might
* be many resources from MediaWiki's perspective. But it totally fails for
* a POST, since what HTTP sees as "the resource" is probably just
* "/api.php" with all the interesting bits in the body.
*
* Therefore, we only support RFC 7232 precondition headers for GET (and
* HEAD). That means we don't need to bother with If-Match and
* If-Unmodified-Since since they only apply to modification requests.
*
* And since we don't support Range, If-Range is ignored too.
*
* @since 1.26
* @param ApiBase $module Api module being used
* @return bool True on success, false should exit immediately
