Wir verwenden NodeJS und Express in Kombination mit für immer. Das hat gut funktioniert, aber jetzt mussten wir unsere NodeJS-Version aktualisieren und alles funktioniert nicht mehr.Kann nicht erhalten, wenn für immer mit Knoten und Express
Wir verwenden Angular mit UI-Routing für Front-End-Routing, so dass wir einen statischen Ordner haben. Ich kann auf unsere Homepage (/) gehen und von dort aus kann ich zur ganzen Seite navigieren. Aber wenn ich eine Seite zu aktualisieren, oder ich gehe direkt auf eine Seite (zB./Produkte) bekomme ich ein
Kann nicht GET/Produkte
Fehler. Knoten gibt einen Fehler 404.
Wenn ich das Skript direkt ohne für immer laufen alles funktioniert gut. Wie Sie sehen können, haben wir 2 statische Ordner in Express konfiguriert. Vor dem Update funktioniert alles einwandfrei.
Wir verwenden auch Apache, um benutzerdefinierte Domänennamen zu bestimmten Seiten umzuleiten, ohne die Adresse im Browser zu ändern, aber das funktioniert gut (zeigt nur den GET-Fehler anstelle der Seite). Hat jemand eine Idee, wie man das löst?
