Paginierung durchlaufen

Python

def get_all_items(base_url, headers):
    """Alle Seiten einer paginierten API-Antwort abrufen."""
    items = []
    page = 1

    while True:
        response = requests.get(
            f"{base_url}?page={page}&per_page=100",
            headers=headers
        )
        data = response.json()
        items.extend(data["data"])

        meta = data.get("meta", {})
        if page >= meta.get("last_page", 1):
            break
        page += 1

    return items

all_inventories = get_all_items(
    "https://ihre-instanz.example.com/api/v2/inventories",
    headers

if response.status_code == 401:
    print("Token ungültig oder abgelaufen — neuen Token erstellen")
elif response.status_code == 403:
    print("Keine Berechtigung für diese Aktion")
elif response.status_code == 404:
    print("Datensatz nicht gefunden")
elif response.status_code == 422:
    errors = response.json().get("errors", {})
    for field, messages in errors.items():
        print(f"Feld '{field}': {', '.join(messages)}")
elif response.status_code >= 500:
    print("Serverfehler — Anwendungslogs prüfen")
else:
    data = response.json()
    print(f"Erfolg: {data}")
