Spritpreise einlesen

michihorn

Hallo

habe mir das Script von Pix angeschaut, doch leider bin ich überfordert.

Ich habe mir meinen Tankerkönig API besorgt und eingetragen und auch die Tankstellen-ID's .

Wie gehe ich den nun weiter mit dem Script um? Wo läuft das dann?

Gruß

Michael

Hallo michihorn,

wenn du die API und die Tankstellen ID oben im Skript einträgst, dann ist eigentlich schon alles getan.

Voraussetzung ist allerdings, dass du den Javascript Adapter installiert und aktiviert hast. Wenn ja, dann im Reiter Skripte ein neues Skript anlegen (Name zB spritpreise) und das Skript einfügen, speichern und links neben dem Skriptnamen auf den roten Knopf drücken und so das Skript starten. Evtl. daneben den Knopf Reload (Pfeile) nochmal drücken. Dann sind die Datenpunkte im Reiter Objekte vorhanden und du kannst sie in VIS verwenden.

Wer macht denn daraus endlich einen Adapter?

Ich will keinen zu sehr ansehen ;-)

Bitte dran denken, das Tankerkönig eine neue Abfrage gebaut hat.

Man kann nun mit einem einzigen Request zig Tankstellen auf einmal abfragen (Antwort als JSON) - die Rückgabe-Daten sind aber erheblich weniger als bei der Detailabfrage.

Tankerkönig hatte mich angeschrieben und ich habe den neuen Request mal durchgetestet.

Als Rückmeldung kommt bei diesem Request "nur":

Tankstellen-ID
Preis E5
Preis E10
Preis Diesel
Öffnungsstatus (offen / zu)

Ich kann die neue Methode gerne als Node-Red-Flow bereitstellen. Kurze Info genügt.

Gruß,

Eric

Das ist ja super.

Nächste Woche kann ich ich darum mal kümmern. Die Daten reichen ja für die Ausgabe. :D

Ich poste den Node-Red-Flow dann heute Abend hier rein.

Den Status der jeweiligen Tanke (open / closed) habe ich mir in 1 / 0 umgerechnet/umgebaut - läßt sich in VIS besser verarbeiten. Man könnte auch true / false nehmen.

Die Zuweisung der Daten zu den Datenpunkten mit dem "lesbaren" Tankstellennamen (es wird ja nur mit der ID gearbeitet) habe ich manuell gemacht - da können wir mal schauen, ob das eleganter geht (im Adapter zwei Eingabefelder pro Tanke : ID und Display-/Datenpunktname).

Gruß,

Eric

hi ho,

hier der Node-Red-Flow für die Ermittlung der Tankstellen-ID anhand von Geodaten. Ist noch viel Handarbeit … wird in Node-Red ja nur einmal benötigt

Bitte dran denken, das Tankerkönig eine neue Abfrage gebaut hat.

Man kann nun mit einem einzigen Request zig Tankstellen auf einmal abfragen (Antwort als JSON) - die Rückgabe-Daten sind aber erheblich weniger als bei der Detailabfrage.

Tankerkönig hatte mich angeschrieben und ich habe den neuen Request mal durchgetestet.

Als Rückmeldung kommt bei diesem Request "nur":

Tankstellen-ID

Preis E5

Preis E10

Preis Diesel

Öffnungsstatus (offen / zu)

Ich kann die neue Methode gerne als Node-Red-Flow bereitstellen. Kurze Info genügt.

Gruß,

Hallo zusammen,

ich habe das Script aus dem ersten Thread mit erfolg eingebunden.

Nur bekomme ich nun eine sehr Freundliche Mail vom Tankerkönig mit folgendem Inhalt

! Hallo Dirk,
! könntest Du statt detail.php bitte prices.php verwenden.
! Grund: detail.php ist recht aufwändig: es werden mehrere Tabellen verwendet, um alle Informationen zusammenzustellen. Die meisten Infos ändern sich nur selten.
! Für Preisupdates bitte immer prices.php verwenden. Damit lassen sich die Spritpreise für bis zu 10 Tankstellen gleichzeitig abrufen.
! Also:
! - weniger Requests
! - geringerer Query-Aufwand
! - weniger Daten zu übertragen
! -> Unser Server wird weniger stark belastet, mehr User können bedient werden.
! siehe -> https://creativecommons.tankerkoenig.de/#usage
Gibt es eine Script Anpassung, oder soll ich die Node Varianten nutzen?

Ich kümmere mich nächste Woche darum. Ist gerade zu wenig Zeit übrig. Wenn du nicht warten willst, nimm erics Flow.

Hallo pix,

Ich werde auf dich warten. :)

Danke für das Tolle Script.

Wie wirkt sich eigentlich das Ergebniss aus ? Wird es Tabelarisch dargestellt wie bei Tankerkönig oder per Map wo man die Tankstellen im Umkreis sieht ?

Ich persönlich finde eine Map Ansicht besser da man Direkt sieht wo was am günstigsten ist.

Ist das Realisierbar bzw bereits integriert ?

Du kannst die Map gern mit iFrame in VIS einbinden.

Eine Karte ist nicht integriert und nicht geplant (in naher Zukunft).
