HTTP/REST-Konnektor

Übersicht

Der HTTP-Konnektor ermöglicht die Kommunikation mit REST-APIs und Webdiensten.

Konnektor-Typen:

• HttpReader - HTTP-Endpunkte abfragen (GET-Anfragen)
• HttpWriter - Daten an HTTP-Endpunkte senden (POST, PUT, DELETE)

HTTP Reader

Periodisches Abfragen eines HTTP-Endpunkts:

{
  "type": "HttpReader",
  "config": {
    "endpoint": "http://api.example.com/data",
    "pollingRate": 5000,
    "method": "GET",
    "headers": {
      "Authorization": "Bearer YOUR_TOKEN",
      "Accept": "application/json"
    }
  }
}

HTTP Writer (POST)

Daten via POST senden:

{
  "type": "HttpWriter",
  "config": {
    "endpoint": "http://api.example.com/data",
    "method": "POST",
    "headers": {
      "Content-Type": "application/json",
      "Authorization": "Bearer YOUR_TOKEN"
    }
  }
}

HTTP Writer (PUT)

Daten via PUT aktualisieren:

{
  "type": "HttpWriter",
  "config": {
    "endpoint": "http://api.example.com/data/123",
    "method": "PUT",
    "headers": {
      "Content-Type": "application/json"
    }
  }
}

Konfigurationsparameter

• endpoint: Vollständige URL einschließlich Protokoll
• method: HTTP-Methode (GET, POST, PUT, DELETE)
• pollingRate: (Nur Reader) Abfrageintervall in Millisekunden
• headers: Benutzerdefinierte HTTP-Header (Objekt)
• timeout: (Optional) Anfrage-Timeout in Millisekunden

Häufige Header

{
  "headers": {
    "Content-Type": "application/json",
