Server-Code: Ich verwende die folgenden Versionen der Bibliotheken: libpion-dev 5.0.6 libboost-all-dev 1.58.0 Im Internet gefunden ein einfaches Beispiel für einen asynchronen HTTP-Server, aber es fällt in die Verarbeitung von Anfragen, für die der Behandler beschrieben wird. Bei nicht vorhandenen Ressourcen wird die 404-Antwort korrekt zurückgegeben.

In diesem Beispiel wird die Anfrage http://127.0.0.1:8080/none 404 ohne Absturz zurückgibt, und http://127.0.0.1:8080/test abstürzen. Ich kann nicht verstehen, was der Grund ist und wie man es richtig macht. Bibliothek haben keine Dokumentation, vielleicht etwas nicht berücksichtigt. Bitte helfen Sie.
