This article uses an Azure Function for demonstration purposes, however the same concepts apply regardless of where the application is hosted. だれかがイベントにサブスクライブするたびに、Event Grid は、データ ペイロード内に validationCode を含む検証イベントをエンドポイントに送信します。Every time someone subscribes to an event, Event Grid sends a validation event to the endpoint with a validationCode in the data payload. Even searching for ‘Azure Function Event Grid Trigger’ on Bing and it’s the first result that comes up, at least for me. It offers a simple event system which operates on a push-push model (rather than push-pull). You should see the blob URL output in the function log: Blob ストレージ アカウントまたは General Purpose V2 (GPv2) Storage アカウントを作成し、. サード パーティ製 API サービス (Zapier や IFTTT など) を使用する場合は、検証コードをプログラムでエコーできないことがあります。If you use a third-party API service (like Zapier or IFTTT), you might not be able to programmatically echo the validation code. Event Grid Basic レベル Event Grid Basic レベルの料金は、実行された操作に基づく従量課金制です。操作には、ドメインまたはトピックへのイベントのイングレス、詳細一致、配信試行、管理呼び出しが含まれます。プランの価格には、月間 100,000 操作の無料提供が含まれています。 The first thing that we'll do is create an Event Grid topic. この記事では、イベント サブスクリプションからイベントを受信する HTTP エンドポイントを検証した後、イベントを逆シリアル化する方法を説明します。This article describes how to validate an HTTP endpoint to receive events from an Event Subscription and then receive and deserialize events. 他の言語用の SDK は、発行 SDK リファレンスを介して利用できます。SDKs for other languages are available via the Publish SDKs reference. You also only pay for what you use, you don’t pay a monthly fee. く お勧めします。It is strongly recommended that you use an Event Grid Trigger when triggering an Azure Function with Event Grid. これは、イベント データを StorageBlobCreatedEventData など、適切な型に逆シリアル化します。It deserializes the event data into the appropriate type, such as StorageBlobCreatedEventData. Verifying Azure Event Grid and Azure Function are Linked Let’s take a look first at our Azure Function.Go into the Function > Click Integration > Verify Event Grid Trigger … これらは、メッセージ ヘッダーで受け取るプロパティです。These are the properties you receive in the message headers: 次のいずれかの値を指定できます。It can be one of the following values: イベントのメタデータ バージョン。Metadata version of the event. If you have the Azure CLIinstalled, you can quickly create a topic on the command line. Event Grid のイベント スキーマ の場合、このプロパティはメタデータのバージョンを表し、クラウド イベント スキーマ の場合は 仕様のバージョン を表します。For Event Grid event schema, this property represents the metadata version and for cloud event schema, it represents the spec version. project.json ファイルに次の内容を追加し、保存します。Add the following contents to the project.json file and save it: 最初に実行することは、Microsoft.EventGrid.SubscriptionValidationEvent イベントの処理です。The first thing you want to do is handle Microsoft.EventGrid.SubscriptionValidationEvent events. C# では、SDK は、イベントの種類名の、イベントのデータ型へのマッピングをサポートします。. For those services, you can manually validate the subscription by using a validation URL that is sent in the subscription validation event. In this post we’ll look at how to locally debug an Azure Function that is configured with an Event Grid trigger. In the Azure portal, you can search for and create an Event Grid Topic. Microsoft.Azure.EventGrid.EventTypesクラスを使用してサポートされているイベントの種類と名前を取得します。Use the Microsoft.Azure.EventGrid.EventTypes class to get supported event types and names. HTTP によってトリガーされる関数を含む関数アプリが必要です。You need a function app with an HTTP triggered function. Event Grid connects your app with other services. サンプル イベントを関数のテスト フィールドに貼り付けることによって、検証応答関数をテストします。Test the validation response function by pasting the sample event into the test field for the function: [実行] をクリックすると、200 OK と、本文に {"validationResponse":"512d38b6-c7b8-40c8-89fe-f46f9e9622b6"} が出力されます。When you click Run, the Output should be 200 OK and {"validationResponse":"512d38b6-c7b8-40c8-89fe-f46f9e9622b6"} in the body: 次に、Microsoft.Storage.BlobCreated を処理するように関数を拡張してみましょう。Now, let's extend the function to handle Microsoft.Storage.BlobCreated: テスト フィールドに BLOB ストレージ イベントを配置して実行することで、関数の新しい機能をテストします。Test the new functionality of the function by putting a Blob storage event into the test field and running: 関数ログに BLOB URL が出力されます。You should see the blob URL output in the function log: Blob ストレージ アカウントまたは General Purpose V2 (GPv2) Storage アカウントを作成し、イベント サブスクリプションを追加し、エンドポイントを関数 URL に設定してテストすることもできます。You can also test by creating a Blob storage account or General Purpose V2 (GPv2) Storage account, adding and event subscription, and setting the endpoint to the function URL: 最後に、関数をもう一度拡張して、カスタム イベントも処理できるようにしましょう。Finally, lets extend the function once more so that it can also handle custom events. イベントのデータ バージョン。Data version of the event. 代わりに、HTTP トリガーを使用してください。 Instead, use an HTTP trigger. C# (2.x You don’t even have to scale it, it does that automatically. Azure portal For functions that you develop in the Azure portal with the Event Grid trigger, select Integration then choose the Event Grid Trigger and select Create Event Grid subscription . I hope to support more location of Azure at that 検証コードをプログラムでエコーするには、次のコードを使用します。To programmatically echo the validation code, use the following code.
