c# - Azure:指定的容器不存在，Dapr 与 ContainerApps

Question

我正在使用 Dapr Azure Blob 存储绑定(bind)来设置文件存储

这是二头肌

存储帐户.bicep

@description('The location in which the Azure Storage resources should be deployed.')
param location string

@description('The name of the blob container.')
var containerName = 'ifms-filestore'

resource storageAccount 'Microsoft.Storage/storageAccounts@2022-05-01' = {
  name: 'ifmsstorageaccount'
  location: location
  sku: {
    name: 'Standard_LRS'
  }
  kind: 'BlobStorage'
  properties: {
    accessTier: 'Hot'
  }
}

resource container 'Microsoft.Storage/storageAccounts/blobServices/containers@2022-05-01' = {
  name: '${storageAccount.name}/default/${containerName}'
}

output storageAccountId string = storageAccount.id
output storageAccountApiVersion string = storageAccount.apiVersion
output storageAccountName string = storageAccount.name
output storageAccountContainerName string = container.name

blobstorage.bicep

param containerAppsEnvironmentName string
param storageAccountId string
param storageAccountApiVersion string
param storageAccountName string
param storageAccountContainerName string

resource containerAppsEnvironment 'Microsoft.App/managedEnvironments@2022-06-01-preview' existing = {
  name: containerAppsEnvironmentName

  resource daprComponent 'daprComponents@2022-03-01' = {
    name: 'ifms-dapr-filestore'
    properties: {
      componentType: 'bindings.azure.blobstorage'
      version: 'v1'
      secrets: [
        {
          name: 'storage-account-account-key'
          value: listKeys(storageAccountId, storageAccountApiVersion).keys[0].value
        }
      ]
      metadata: [
        {
          name: 'accountName'
          value: storageAccountName
        }
        {
          name: 'accountKey'
          secretRef: 'storage-account-account-key'
        }
        {
          name: 'containerName'
          value: storageAccountContainerName
        }
        {
          name: 'decodeBase64'
          value: 'true'
        }
      ]
      scopes: [
        'vehicle-management-web-api'
      ]
    }
  }
}

output daprPubSubName string = containerAppsEnvironment::daprComponent.name

AddFileAsync 是一个辅助函数，用于将文件添加到文件存储并使用 DaprtClinet 来执行此操作。

public async Task<FileReturnType> AddFileAsync(byte[] fileContent, string path, string fileName)
{
  var filepath = Path.Combine(path, fileName);

  string base64String = Convert.ToBase64String(fileContent, 0, fileContent.Length);
  Dictionary<string, string> metadata = new Dictionary<string, string>{ {"blobName",filePath}};

  await _daprClient.InvokeBindingAsync("ifms-dapr-filestore", "create", base64String, metadata);
  long fileSize = fileContent.Length;
  var extension = Path.GetExtension(fileName);

  return new FileReturnType(filepath, fileSize, extension);
}

当我添加文件时，我收到以下错误消息

Dapr.DaprException: Binding operation failed: the Dapr endpoint indicated a failure. See InnerException for details.

Azure 存储和容器均在 Azure 上配置，如下图所示

Answer 1

我认为问题出在您的 storageAccountContainerName 中，查看错误响应似乎采用 {storageaccountName}/default/{actualContainerName} 的格式。

输出中 PUT 请求中的 URL 以 https://ifmsstorageaccount.blob.core.windows.net/ifmsstorageaccount/default/ifms-filestore/ 开头，格式为 https://{storageAccountName}.blob.core.windows.net/{storageAccountName}/default/{containerName}/{blobName} 而应该是 https://{storageAccountName}.blob .core.windows.net/{containerName}/{blobName}

尝试将 storageaccount.bicep 中的输出更改为:

output storageAccountContainerName string = last(split(container.name, '/'))
