In diesem Leitfaden erfahren Sie, wie Sie die VersionHistory Web Service API verwenden.
Überblick
Die VersionHistory API bietet programmatischen Zugriff auf Informationen zum Versionsverlauf von Google Chrome und Fuchsia Web Engine. Es ist eine REST API, die Informationen im JSON-Format zurückgibt.
Der API-Zugriff erfolgt über HTTPS und der Zugriff erfolgt über https://versionhistory.googleapis.com/v1.
Alle Plattformen abrufen
Chrome wird auf vielen verschiedenen Plattformen unterstützt, z. B. Windows, iOS und Android. So rufen Sie alle Plattformen auf, zu denen VersionHistory Informationen enthält:
GET https://versionhistory.googleapis.com/v1/chrome/platforms/

Alle gültigen Kombinationen aus Plattform und Kanal abrufen
Chrome stellt auf vielen unterstützten Plattformen mehrere Kanäle zur Verfügung. So rufen Sie alle gültigen Kombinationen aus Plattform und Kanal auf:
GET https://versionhistory.googleapis.com/v1/chrome/platforms/all/channels

Alle gültigen Channels für eine bestimmte Plattform abrufen
In den vorherigen Beispielen wurde der Parameter all verwendet, um VersionHistory anzuweisen, Informationen zu allen Plattformen abzurufen. Wenn Sie sich auf eine bestimmte Plattform konzentrieren möchten, ersetzen Sie all durch eine bestimmte Plattform-ID (z. B. win):
GET https://versionhistory.googleapis.com/v1/chrome/platforms/win/channels

{
"channels": [
{

]
}
Versionsinformationen für eine bestimmte Kombination aus Plattform und Kanal abrufen
Eine Version stellt die spezifische Instanz von Chrome dar, die Nutzer ausführen. Senden Sie eine GET-Anfrage wie die folgende, um Versionsinformationen für eine bestimmte Kombination aus Plattform/Kanal abzurufen:
GET https://versionhistory.googleapis.com/v1/chrome/platforms/win/channels/stable/versions
Diese Anfrage ruft alle Versionen von Google Chrome (stabile Version) ab, die unter Windows ausgeführt wurden.
