Description

Following code works fine:

myResource_ = std::make_unique<MyResource>(); //myResource_->setInternalPath("myresource"); root()->addWidget(std::make_unique<WAnchor>(WLink(myResource_->url()), "Resource"));
(with MyResource subclass of WResource)
Clicking on the link displays the content generated by myResource_, as expected

However when the second line is uncommented the clicking on the link returns a 403 forbidden error.
Also entering the url as

http:///myresource or http:///?_=myresource

does not work. Tested with Wt 4.5.0

Update: urls at the end are wrong (part was interpreted as markdown)
should be:

http://myserver/myresource or http://myserver/?_=myresource

Updated by Geert Verbruggen over 1 year ago

Cause of the error seems to be that &request=resource is not added to the url for a WResource with internalPath set.

As a consequence requestForResource evaluates to false at WebSession.C, line 1328, and request handling ends at WebSession.C line 1385:

if (env_->ajax()
      && isEqual(request.requestMethod(), "GET")
      && !requestForResource
      && conf.reloadIsNewSession()
      && wtdE && *wtdE == sessionId_) {
    LOG_SECURE("Unexpected GET request with wtd of existing Ajax session");
    serveError(403, handler, "Forbidden");
    return;
}
