Azure cosmos 数据库触发器

Question

是否可以在 Azure 管道中调用 cosmos db 触发器？管道只是将数据从 azrue 存储复制到 cosmos db 集合，需要调用预触发器。如何为复制活动指定触发器ID？

Answer 1

根据您的说法，您可以通过使用带有 Blob Trigger 和 DocumentDB output binding 的 Azure Functions 来解决此问题。

与functions.json 类似：

{
    "disabled": false,
    "bindings": [
        {
            "name": "myBlob",
            "type": "blobTrigger",
            "direction": "in",
            "path": "<name-of-the-folder-where-files-get-uploaded>",
            "connection":"MyStorageAccount"
        },
        {
          "name": "documentToSave",
          "type": "documentDB",
          "databaseName": "MyDatabase",
          "collectionName": "MyCollection",
          "createIfNotExists": true,
          "connection": "MyAccount_COSMOSDB",     
          "direction": "out"
        }
    ]
}

函数体可能是这样的：

// Blob trigger binding to a CloudBlockBlob
#r "Microsoft.WindowsAzure.Storage"

using Microsoft.WindowsAzure.Storage.Blob;

public static void Run(CloudBlockBlob myBlob, out object documentToSave, TraceWriter log)
{
    // some logic to read the blob and parse it

    documentToSave = new {
        id = "some value",
        .. other properties here
      };
}
