如何在逻辑应用程序中附加来自不同文件夹的多个BLOB？ [英] How to attach multiple blobs in logic app from different folder?

问题描述

你好，我在蔚蓝逻辑应用程序工作。我的Blob存储中有以下Blob。

Predesign/guid/AdditionalDocument/somefile.ext
Predesign/guid/CalcOutput/somefile.ext
Predesign/guid/DataSheet/somefile.ext

下面的步骤是列出我给出的BLOB示例路径preDesign/GUID(在实际实现中，我将GUID视为动态)。如上所述，在GUID中我有多个子文件夹

然后我有发送电子邮件活动来发送带有附件的电子邮件。当我运行代码时，出现以下错误

{
  "status": 404,
  "message": "Specified blob PreDesign/1e36d504-7876-41b1-89b3-83d2132fa7c4/AdditionalDocumets/ does not exist.
clientRequestId: fcb3f5d4-aca2-4c8e-bb8d-543d31fa9cb3",
  "error": {
    "message": "PreDesign/1e36d504-7876-41b1-89b3-83d2132fa7c4/AdditionalDocumets/ does not exist."
  },
  "source": "azurewebsites.net"
}

其他Documets、CalcOutput和Data Sheet三个文件夹出现相同的错误。因此，基本上我无法从这些不同的文件夹中获取内容。有人能帮我附加不同文件夹中的多个文档吗？任何帮助都将不胜感激。谢谢您

推荐答案

您收到此错误可能是由于以下原因之一。

1. 拼写错误的路径。 如果您提到的路径是手动编写的，请尝试使用打开文件框指向正确的文件夹。因为我看得出你一开始提到了前期设计，但同时提到了它

2. 连接失败 您可能无法从逻辑应用连接器连接到您的存储帐户。尝试创建与您的存储帐户的新连接。

有人能帮我附加不同文件夹中的多个文档吗？

假设文件夹结构如下

Container  
|  
|  
____Directory 1  
|   ____Blob 1  
|   
|  
____Directory 2   
    ____Blob 2  
    ____File 3   

方式-1

您可以有2个List blobs个连接器，并对它们进行迭代。以下是我的逻辑应用程序的截图以供参考。

输出

目录1中的Blob列表

目录2中的Blob列表

方式2

您可以在for each内使用for each循环。这是我的逻辑应用程序的屏幕截图。

输出：-

当有许多我们要迭代的文件夹时，这些方法可能有点笨拙。在这种情况下，最有效的方法是使用Azure函数。有关这方面的详细信息，请参阅Get List of all files from all folder
