azure - 将数组类型作为参数传递给 AppService 插槽的应用程序设置时出错

Question

使用“数组”类型的参数替换为网站槽应用程序设置的 AppService 部署失败，并出现以下错误。

2019-10-20T10:25:46.0572018Z ##[error]BadRequest: {
  "Code": "BadRequest",
  "Message": "HTTP request body must not be empty.",
  "Target": null,
  "Details": [
    {
      "Message": "HTTP request body must not be empty."
    },
    {
      "Code": "BadRequest"
    },
    {
      "ErrorEntity": {
        "ExtendedCode": "51016",
        "MessageTemplate": "HTTP request body must not be empty.",
        "Parameters": [],
        "Code": "BadRequest",
        "Message": "HTTP request body must not be empty."
      }
    }
  ],
  "Innererror": null
}

使用的模板如下。当 Email__ToEmailAddress 参数更改为字符串类型时，部署会成功，但作为数组类型时，部署会失败。传递一个空数组或具有多个值的数组没有区别。

感谢所有回复。

Answer 1

这可能与参数函数解析数组的方式有关。

尝试:

[数组(参数('Email__ToEmailAddress'))]

或者:

[[参数('Email__ToEmailAddress')]]

希望这有帮助。
