iOS Widget, welches anzeigt ob im lokalen Impfzentrum Vermittlungscodes verfügbar sind. (für die scriptable.app)

impfTermin.js

/* 
Impftermin Widget
v 1.3.0

This Scriptable Widget will show you if there are any "Vermittlungscode" for vaccination appointments available.
The data is pulled from the impfterminservice.de api, which is neither publicly available nor documented.
Therefore everything may break.

The newest version, issues, etc. of this widget can be found here: https://github.com/not-a-feature/impfWidget
A gist version is also available: https://gist.github.com/not-a-feature/4e6dbbd9eb3bd927e50cae347b7e0486/

The framework/skeleton of this script was created by marco79cgn for the toiletpaper-widget
(https://gist.github.com/marco79cgn/23ce08fd8711ee893a3be12d4543f2d2)

To uses this widget go to https://003-iz.impfterminservice.de/assets/static/impfzentren.json and search for
your local center. Copy the whole text in between the two curly brackets and paste it below in the settings (Starting at line 55).

If you want a notification change the NOTIFICATION_LEVEL to 
0: no notification
1: only if vaccines are available
2: every time the widget refreshes

If you want to know if there are appointments specifically for a vaccine,
set DISPLAY_VACCINES_AS_ONE to false. This requires a medium size-widget (2x1)

If you want to exclude specific vaccines, set them to inside the VACCINES variable to false. 

Thats it. You can now run this script.
Copy the source, open the scriptabel app, add the source there. 
go the home screen, add scriptable widget

Installation & Git-Repo

Eine Anleitung, Pullrequests, Issues und Kommentare finden auf dem Git Repo: https://github.com/not-a-feature/impfWidget
Auf dem GIST (hier) wird nur die neuste Version aktualisiert.

Changelog

• v 1.3.0 introducing Notifications
• v 1.2.3 changing api to subdomain
• v 1.2.2 changing licence url & comment
• v 1.2.1 removing whitespace in name-replace function
• v 1.2 added detail-view and updated licence to GNU GPLv3
• v 1.1.1 fixed typo in BLAND ID explanation
• v 1.1 added AstraZeneca Vaccine (L922)
• v. 1.0 initial Release

Vielen Dank! Funktioniert super und war genau was ich gesucht hab.

Wollte erst selbst den JSON mit JS auslesen und anzeigen, aber bekomme ständig CORS Fehler. Wieso funktioniert das bei dir? (sorry für die dumme Frage :/)

Für Ersttermine muss es anscheinend ein Terminpaar geben, damit freie Termine angezeigt werden.

Bsp. für ein Impfzentrum wird folgendes zurück geliefert: {"termineVorhanden":true} Wenn man dann einen Termin buchen möchte gibt es keine Termine, der Json von terminpaare liefert folgendes:

{
"gesuchteLeistungsmerkmale": [
"L922"
],
"terminpaare": [],
"praxen": {}
}

Dadurch dass Scriptable kein Browser ist und CORS / SOP nicht implementiert hat brauche ich mich damit nicht zu sorgen.
Browser hingegen erlauben es nicht, Inhalte von anderen Quellen (also Cross Origin) nachzuladen wenn keine passende CORS-Header in der Antwort gesetzt sind. Das zu umgehen ist i.d.R nicht ohne weiteres Möglich.

Zum Zweiten Komentar:
Ja das ist mir bewusst, dieses Widget ist (aktuell) nur zur Vermittlungscode-Vergabe (steht auch so in der Anleitung/Code).

Gestern hatte ich eine gute Konversation diesbezüglich: https://twitter.com/not_a_feature/status/1367152386909888515?s=21
Gerne kannst du auf dem Git Repo aber ein Issue aufmachen, ich habe schon eine Lösung dafür im Kopf: https://github.com/not-a-feature/impfWidget/issues
