Azure cosmos db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？

根据您所说的，您可以通过使用带有Blob触发器和DocumentDB输出绑定的Azure Functions来解决这个问题。

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"
        }
    ]
}

函数体可以是这样的:

// 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
      };
}
