Microsoft Entra Uygulaması ile Azure Event Grid'de Güvenli WebHook iletimi

Bu betik, Azure Event Grid kullanarak Microsoft Entra Uygulaması tarafından korunan HTTPS uç noktalarına olay teslim etmek için yapılandırma sağlar.

Komut dosyasının ana adımları şunlardır;

1. Henüz yoksa, Microsoft.EventGrid için bir hizmet sorumlusu oluşturun.
2. Webhook'unuz için Microsoft Entra uygulamasında AzureEventGridSecureWebhookSubscriber adlı bir rol oluşturun.
3. Henüz yoksa olay aboneliği yazıcı uygulaması için bir hizmet ilkesi oluşturun.
4. AzureEventGridSecureWebhookSubscriber rolüne olay aboneliği yazıcısı Microsoft Entra uygulamasının hizmet sorumlusunu ekleme
5. Microsoft.EventGrid hizmet sorumlusunu AzureEventGridSecureWebhookSubscriber rolüne de ekleyin.

Microsoft.EventGrid uygulama kimliğini alma

1. Azure portala gidin.

2. Arama çubuğuna yazın Microsoft.EventGridve açılan listeden Microsoft.EventGrid (Hizmet Sorumlusu) öğesini seçin.

   

3. Microsoft.EventGrid sayfasında Uygulama Kimliğini not edin veya panoya kopyalayın.

4. Aşağıdaki betikte, değişkeni çalıştırmadan önce bu değere ayarlayın $eventGridAppId .
