（400）通过ARM

希望有人可以告诉我这个ARM模板部署的错误。

使用问题底部的模板，我可以使用应用服务计划和存储帐户部署功能应用程序 - 但是我收到以下错误。

                        },
                        {

                                ],

                        }],
                        "Innererror": null
                    }
RESOURCE            functionname/appsettings

如果我从模板的功能应用程序部分删除此AppSetting属性，那么部署工作正常。

"WEBSITE_CONTENTAZUREFILECONNECTIONSTRING": "[concat('DefaultEndpointsProtocol=https;AccountName=',parameters('Storage_Account_Name'),';AccountKey=',listKeys(resourceId('Microsoft.Storage/storageAccounts', parameters('Storage_Account_Name')),'2015-05-01-preview').key1)]",

但是当我转到已部署的功能应用程序时，我会收到此错误弹出窗口。

Error:

'WEBSITE_CONTENTAZUREFILECONNECTIONSTRING' application setting is missing from your app. This setting contains a connection string for an Azure Storage account that is used to host your functions content. Your app will be completely broken without this setting. You may need to delete and recreate this function app if you no longer have access to the value of that application setting.

我还注意到，如果我尝试在成功部署后手动在门户中添加该appsetting，我会得到与初始部署相同的错误。

因此，我不知道我是否错误地将其放入模板中，或者Azure部署功能应用中的内容是否已损坏。

我哪里错了？

通常情况下，在花了一天左右的时间试图找出问题之前，在发生故障并求助于SO之前，我会尽快找出错误。

问题不在于WEBSITE_CONTENTAZUREFILECONNECTIONSTRING，而在于WEBSITE_CONTENTSHARE。它有一个下划线，存储帐户文件共享的命名约定中不允许使用下划线。

所以，请注意，当我看到像这样的错误时发生了冲突... ，请想一下 ...使用命名约定，而不是。 ..使用现有资源。

我还必须将3个Azure URL添加到CORS AllowedOrigins部分

"https://functions.azure.com",
"https://functions-staging.azure.com",
"https://functions-next.azure.com"

不确定它是否与问题直接相关，但我建议您使模板更类似于Portal默认使用的模板。要看到这个：

  • 开始在Azure门户中创建新功能应用程序的过程
  • 输入一些任意应用名称和资源组
  • 点击底部的“自动化选项”链接

你将获得它使用的完全严格。它看起来像这样：

答案 2 :(得分：0)

由于这些appsettings，我的Azure部署尤其是功能应用程序也失败了。以下是我的ARM脚本的摘录。

"siteConfig": {
   "appsettings": [
   {
     "name": "AzureWebJobsDashboard",
     "value": "[Concat('DefaultEndpointsProtocol=https;AccountName=',variables('StorageAccountName'),';AccountKey=',listKeys(resourceId('Microsoft.Storage/storageAccounts', variables('StorageAccountName')), providers('Microsoft.Storage', 'storageAccounts').apiVersions[0]).keys[0].value)]"
   },
 ]

该值用于以下设置：AzureWebJobsDashboard，AzureWebJobsStorage，WEBSITE_CONTENTAZUREFILECONNECTIONSTRING。 取决于我的存储帐户也在ARM脚本中设置。

我正在通过Visual Studio Team Services开始部署。我弄错了。我直接从Azure收到错误消息。

  • 资源：Azure-Function-Dev
  • 类型：Microsoft.Web / sites

  • 状态：BadRequest

    { “错误”：{ “code”：“InternalServerError”， “message”：“出现意外的InternalServerError。请稍后再试.x-ms-correlation-request-id：44444-4444 ...” } }

如果再次重新部署功能应用程序 - 没有任何更改 - 部署始终有效。奇怪的行为。

然后我使用我的参数将我的值设置为固定值。从那时起，部署运行没有问题。这可能不是技术上干净的解决方案，但可以分析错误

"siteConfig": {
      "appsettings": [
        {
          "name": "AzureWebJobsStorage",
          "value": "[parameters('AzureWebJobsStorage')]"
        }, ]

答案 3 :(得分：0)

TLDR;

检查存储帐户名称是否正确并且只能使用小写字母。

长版

github问题-https://github.com/Azure/azure-cli/issues/14518#issuecomment-665255337

在我的方案中，我正在设置一个新的资源组，新的应用程序服务计划和新功能-但是使用现有的存储帐户并遇到了此问题There was a conflict. The remote server returned an error: (400) Bad Request.

我的问题是我的参数文件的存储帐户名称中出现了大小写问题。 myownstorageaccountTest而不是myownstorageaccounttest

当该myownstorageaccountTest已经存在时，ARM模板部署正在尝试创建一个名为myownstorageaccounttest的新存储帐户。存储帐户名称在整个Azure中必须唯一。

存储帐户名称要求： 该名称在Azure中所有现有存储帐户名称中必须是唯一的。长度必须为3至24个字符，并且只能包含小写字母和数字。

答案 4 :(得分：0)

TL;DR：函数应用名称不得超过 59 个字符

因为这些名称构成了一个主机名，我通常会附加随机数字来填充到最大限制，我相信记录为 60 个字符。

在 Function App 创建向导期间，输入 61 个字符的名称会正确拒绝表单中的名称： Function app with 61 chars “必须小于 60”的错误消息与“59 或更少”相同，但输入 60 - 我在别处见过 - 允许该过程继续： Function app with 60 chars 继续创建函数应用程序最终失败并显示此错误：

{
  "code": "DeploymentFailed",
  "message": "At least one resource deployment operation failed. Please list deployment operations for details. Please see https://aka.ms/DeployOperations for usage details.",
  "details": [
    {
      "message": "There was a conflict. The remote server returned an error: (400) Bad Request."
    }
  ]
}

使用 59 个字符 的名称创建 OK。

这感觉就像表单中的一个围栏错误，它接受的名称比下游进程接受的名称大一个字符。
