我需要将上传到我的 Azure 存储容器的 blob 作为附件发送。上传到容器的文件数量会发生变化，因此我需要使用动态方法进行附件。 I have verified this question related to it
我正在使用以下逻辑:
附加到变量值
{
"Name": items('For_each')?['DisplayName']
"ContentBytes":body('Get_blob_content')
} 当我尝试保存逻辑时，出现以下错误:
Save logic app failed
Failed to save logic app testing. The template validation failed: 'The action(s) 'Get_blob_content' referenced by 'inputs' in action 'Append_to_array_variable' are not defined in the template.'.
我该如何解决这个问题？
最佳答案
根据上面共享的错误消息，建议您在每个阶段或在 appendtoarray 变量 stage & post 之前保存逻辑应用，而不是立即保存整个工作流，然后将值附加到带有前一阶段输出的附件变量。
根据上述要求，我们在本地环境中创建了以下逻辑应用并对其进行了测试，运行良好。
在我们的工作流程中，我们使用 For Each 来循环 List Blobs 操作中的 Blob。在 For Each 中，您可以使用获取 blob 内容来获取 blob 内容，然后使用追加到数组变量来追加附件。
表达式Name和ContentBytes如下:
"ContentBytes": "@base64(body('Get_blob_content_(V2)'))",
"Name": "@items('For_each')?['DisplayName']"
这是我们创建的逻辑应用的代码 View :
