Connettore HTTP/REST

Panoramica

Il connettore HTTP abilita la comunicazione con API REST e servizi web.

Tipi Connettore:

• HttpReader - Polling endpoint HTTP (richieste GET)
• HttpWriter - Invia dati a endpoint HTTP (POST, PUT, DELETE)

HTTP Reader

Polling periodico di un endpoint HTTP:

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

HTTP Writer (POST)

Invia dati via POST:

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

HTTP Writer (PUT)

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

Parametri di Configurazione

• endpoint: URL completo incluso protocollo
• method: Metodo HTTP (GET, POST, PUT, DELETE)
• pollingRate: (Solo Reader) Intervallo polling in millisecondi
• headers: Header HTTP personalizzati (oggetto)
• timeout: (Opzionale) Timeout richiesta in millisecondi

Header Comuni

{
  "headers": {
    "Content-Type": "application/json",
    "Authorization": "Bearer token",
    "Accept": "application/json",
    "User-Agent": "Meddle/1.0"
  }
}

Casi d’Uso

1. Integrazione API Meteo

{
  "type": "HttpReader",
  "config": {
    "endpoint": "https://api.weather.com/v1/current?location=factory",
    "pollingRate": 300000,
    "method": "GET",
    "headers": {
      "API-Key": "your-api-key"
    }
  }
}

2. Integrazione Webhook

{
  "type": "HttpWriter",
  "config": {
    "endpoint": "https://hooks.example.com/webhook",
    "method": "POST",
    "headers": {
      "Content-Type": "application/json"
