Mediawiki（1.26） - 如何从页面内访问404 HTTP状态

Question

when calling a non-existent wiki page mediawiki delievers a 404 in the header.

Is there a way to catch this from the own page (for logging reasons)?

There is a

public function getStatusCode()

in WebResponse.php and in HttpError.php

and in OutputPage.php e.g. there is a

public function setStatusCode( $statusCode )

From within the MonoBookTemplate.php i have an instance of MonoBookTemplate.

But how do i catch from this place the 404 status?

I read about $context->getOutput() but have no clue how to access the status variable.

---

Part-Solution:

As a workaround i added $wgMyStatusCode to the LocalSettings.php and in WebResponse.php:

public function statusHeader( $code ) {
    HttpStatus::header( $code );

    //added
    global $wgMyStatusCode;
    $wgMyStatusCode = $code;
}

Anyway - if someone could me introduce to the secrets of object-orientation in mediawiki - thanks.

Answer 1

!RequestContext::getTitle()->exists()

is probably close enough.
