Wireguard Server abfragen -> Client Infos

[Kuddel]

Die Anzeige der Werte vom Wireguard Adapter über in JSON DP funz schonmal:

Aktuell hänge ich noch an der whois Abfrage.

Die Abfrage an sich funzt, nur mein javascript wartet aktuell nicht, bis die Abfrage eine Antwort gelifert hat. Somit sind die Werte immer undefiniert

@kuddel

So dürfte er erst nach einem Ergebnis oder 2sek weiter machen oder?
Das ist der Code den mit Blockly gibt.

httpGet('https://xxx.de', { timeout: 2000, responseType: 'text' }, async (err, response) => {
   console.info(response.data); 
});

[Kuddel]

@david-g timeout: 2000 bedeutet doch eigentlich nur, dass die Abfrage nicht länger als 2 Sekunden dauern darf.

Eine Pause ist es aber nicht

[David G.]

@kuddel

Das ist das Blockly was mir den Code generiert hat.
Alles innerhalb des httpget Baustsins wird dort erst nach einer Antwort oder 2sek ausgeführt.

Edit
Hier siehst du, dass die der Fehler schon zwischen beiden Warnungen kommt.

Mit einer echten Website hab ich da auch ein result stehen. Nur zu lang für einen Screenshot.

@david-g

ICh bin schon einen Schritt weiter gekommen.

Wenn ich alle weiteren Schritte mit in den HTTP Get Block schreibe funktioniert es.

Problem ist jetzt, dass es nur für verbundene Clients geht.

Morgen mache ich einen erneuten Anlauf, um das Skript für alle Clients lauffähig zu bekommen

[Kuddel]

So, das Skript macht jetzt was es soll

Morgen kommen dann nur noch Optimierungen

[Kuddel]

Mein Script erstellt jetzt folgende zwei JSON Datein:

Oben sieht man den aktuellen Zustand:
Das Land und die Herkunft werden nur abgefragt, wenn sich der Client verbindet oder trennt. Habe da im Test irgednwann eine Ablehnung von der APi bekommen, weil ich zu viele Abfragen gestellt habe.
Des Weiteren läuft das Skript bei Änderungen des Traffics sowie der IP erneut los.

Unten sieht man eine Verbindungshistory, die nur befüllt wird, wenn sich ein Client verbindet oder wieder trennt.

Wenn Interesse besteht, kann ich das Skript gern teilen

Ja bitte!

Und die View auch bitte!

Das Skript habe ich mit freudlicher Unterstützung von ChatGPT erstellt. Ist also nicht nur auf meinem Mist gewachsen ^^

Skript

Sorry, für die seeeeeeehr lange Zeit.
Hab es komplett vergessen.

Ist das Script ohne Anpassung lauffähig?

[Kuddel]

@negalein habe das Skript mal eben fix aufm Handy überflogen.

Sollte ohne Anpassungen laufen.

Danke

Es läuft, mir wird in 0_userdata.0.wireguard-clients.Wireguard-JSON-History der Client gezeigt, der nach Scriptstart verbunden wurde.

Aber 0_userdata.0.wireguard-clients.Wireguard-JSON bleibt leer.
