带有Azure Bicep的Azure EventGrid订阅的Webhook网址失败

编程问答 2022-06-12

问题描述

我是Azure Bicep的新手（它本身我还很新），但是对ARM模板有一定的经验。

我正在尝试学习如何为Azure Blog存储容器创建Azure Event Grid订阅。

这不是生产代码，我一直遵循tutorial，现在正尝试使用未涵盖的EventGrid。

当我部署用二头肌创建的模板时，出现错误：

{
    "error": {
        "code": "InvalidRequest","message": "Invalid event subscription request: Supplied URL is invalid. It cannot be null or empty and should be a proper HTTPS URL like https://www.example.com."
    }
}

我的事件网格订阅如下：

resource sub1 'Microsoft.EventGrid/systemTopics/eventSubscriptions@2020-04-01-preview' = {
    name: '${eventgrid.name}${subscriptionName}'
    properties: {
        destination: {
            properties: {
                maxEventsPerBatch: 1
                preferredBatchSizeInKilobytes: 64
            }
            endpointType: 'WebHook'
        }
        filter: {
            subjectBeginsWith: '/blobServices/default/containers/mycontainer'
            includedEventTypes: [
                'Microsoft.Storage.BlobCreated'
            ]
        }
        labels: []
        eventDeliverySchema: 'EventGridSchema'
        retryPolicy: {
            maxDeliveryAttempts: 30
            eventTimeToLiveInMinutes: 1440
        }
        topicType: 'Microsoft.Storage.StorageAccounts'
    }
}

当我将endpointUrl属性添加到事件订阅时，出现另一个错误：

{
    "status": "Failed","error": {
        "code": "ResourceDeploymentFailure","message": "The resource operation completed with terminal provisioning state 'Failed'.","details": [
            {
                "code": "Url validation","message": "Webhook validation handshake failed for https://foobarblee.blob.core.windows.net/results-nlp. Http POST request failed with response code Unknown. For troublehooting,visit https://aka.ms/esvalidation. Activity id:,timestamp: 9/22/2020 11:21:07 PM (UTC)."
            }
        ]
    }
}

代码部分更改如下：

resource sub1 'Microsoft.EventGrid/systemTopics/eventSubscriptions@2020-04-01-preview' = {
    name: '${eventgrid.name}${subscriptionName}'
    properties: {
        destination: {
            properties: {
                maxEventsPerBatch: 1
                preferredBatchSizeInKilobytes: 64
                endpointUrl: 'https://${storageAccount.name}.blob.core.windows.net/mycontainer'
            }
            endpointType: 'WebHook'

很遗憾，我找不到关于此特定问题的任何文档。

我的整个二头肌文件如下：

param location string = resourceGroup().location
param evgNamePrefix string = 'evg'
param subNamePrefix string = 'sub'
param stgNamePrefix string = 'stg'
param subOneName string = '/foo-local-debug'

// param storageAccountName string = 'blee'

param globalRedundancy bool = true // defaults to true,but can be overridden

var storageAccountName = '${stgNamePrefix}${uniqueString(resourceGroup().id)}'
var eventGridName = '${evgNamePrefix}${uniqueString(resourceGroup().id)}'
var eventGridSubscriptionName = '${evgNamePrefix}${subNamePrefix}${uniqueString(resourceGroup().id)}${subOneName}'

resource evg 'Microsoft.EventGrid/systemTopics@2020-04-01-preview' = {
    name: eventGridName
    location: location
    properties: {
        source: stg.id
        topicType: 'Microsoft.Storage.StorageAccounts'
    }
}

    name: '${evg.name}${subOneName}'

            properties: {
                maxEventsPerBatch: 1
                preferredBatchSizeInKilobytes: 64
                endpointUrl: 'https://${stg.name}.blob.core.windows.net/mycontainer'
            }
            endpointType: 'WebHook'

        }

    }
}

}

    }

        tier: 'Standard'
    }   
}

  properties: {
    defaultEncryptionScope:'$account-encryption-key'
    denyEncryptionScopeOverride: false
    publicAccess: 'None'
  }
}

output storageId string = stg.id
output computedStorageName string = stg.name
output eventGridId string = evg.id
output eventGridsName string = evg.name

解决方法

我基于BICEP文档生成了ARM JSON。 我将Url更改为public webhook，并且可以正常工作：

“ endpointUrl”：“ https://eval-mm.azurewebsites.net/api/Function1”

EventGrid订阅WebHook必须是公共的，并且不支持URL参数或标头。这让我很烦。

享受BICEP，好东西：-）
