azure - 将 blobTrigger 与 Azurite 结合使用会导致函数主机崩溃

Question

我遇到了 Azure blob 触发函数导致函数主机崩溃的问题。这似乎是存储连接字符串或我如何使用 Azurite 的问题。我正在开发的其他计时器或 HTTP 触发器函数可以在“UseDevelopmentStorage=true”设置和运行的 Azurite blob 服务下正常工作。

我对使用 Azurite 存储模拟器在我的开发环境中使用 blob 触发函数可能出现的问题感到困惑。

对我缺少什么或在哪里进一步寻找有什么建议吗？

这是函数主机启动后大约 10 到 20 秒时收到的错误消息:

An unhandled exception has occurred. Host is shutting down.Microsoft.WindowsAzure.Storage: No connection could be made because the target machine actively refused it. System.Net.Http: No connection could be made because the target machine actively refused it. System.Private.CoreLib: No connection could be made because the target machine actively refused it.

blob 触发器函数的 function.json 文件如下所示:

{
  "scriptFile": "__init__.py",
  "bindings": [
    {
      "name": "myblob",
      "type": "blobTrigger",
      "direction": "in",
      "path": "outcontainer/{name}",
      "connection": "AzureWebJobsStorage"
    }
  ]
}

local.settings.json 文件包含以下内容:

{
  "IsEncrypted": false,
  "Values": {
    "AzureWebJobsStorage": "UseDevelopmentStorage=true",
    "FUNCTIONS_WORKER_RUNTIME": "python"
  }
}

这是启用了 --verbose 开关的控制台的输出:

Answer 1

看来我发现我做错了什么。 The documentation says ，“Azure Blob 存储触发器需要通用存储帐户。”

我只是启动了 Azurite blob 服务。启动整个事情就可以了。
