Kurseinführung：Dynamisch einbeziehen oder von Benutzern, um Steuerelemente einzugeben, kann schwerwiegende Sicherheitslücken einführen. 1. Die Anf?lligkeit von Remote File Inclusion (RFI) erm?glicht es den Angreifern, b?swilligen Code über externe URLs zu injizieren. Sie sollten es vermeiden, Fern -URLs zu verwenden und einen Whitelisting -Mechanismus anzuwenden. 2. Die Verwundbarkeit der Lokaldateieinschluss (LFI) erm?glicht es den Angreifern, über Pfadtraversal auf sensible Dateien zuzugreifen. Sie sollten vermeiden, die Benutzereingabe direkt zu verwenden, die Optionslisten mit festen Optionen zu verwenden und die Eingabe streng zu überprüfen. 3. Der Angreifer kann auch Befehle ausführen, indem er PHP -Code in die Protokoll- oder Upload -Datei einfügt. Dynamische Einbeziehung, die Dateiberechtigungen einschr?nken und davon ausgehen, dass alle Dateien m?glicherweise manipuliert werden. Kurz gesagt, Dynamics erfordern eine strenge überprüfung und Konfiguration, wobei sichere Alternativen bevorzugen.

Kurseinführung：jQuery ist ein schnelles und pr?gnantes JavaScript-Framework. Es ist nach Prototype eine weitere hervorragende JavaScript-Codebibliothek (oder JavaScript-Framework). Der Zweck des jQuery-Designs besteht darin, ?weniger zu schreiben, mehr zu tun“, was bedeutet, weniger Code zu schreiben und mehr Dinge zu tun. Es kapselt h?ufig verwendete Funktionscodes in JavaScript, stellt ein einfaches JavaScript-Entwurfsmuster bereit und optimiert HTML-Dokumentvorg?nge, Ereignisverarbeitung, Animationsdesign und Ajax-Interaktion. Wir haben das ?Boolean Education jQuery Practical Video Tutorial“ zusammengestellt, in der Hoffnung, jedem dabei zu helfen, jQuery besser zu erlernen.
