无法连接到本地存储帐户

Question

我按照Microsoft文档部署了一个存储帐户边缘模块，我的模块目前正在我的虚拟机中运行。但是，我无法将Python SDK或存储资源管理器连接到它。

我的容器创建选项是：

{
"Env": [
    "localstorage",
    "92RhvUXR59Aa8h90LSHC7w=="
],
"HostConfig": {
    "Binds": [
        "blobvolume:/blobroot"
    ],
    "PortBindings": {
        "11002/tcp": [
            {
                "HostPort": "11002"
            }
        ]
    }
}
}

我的模块双胞胎设置是

{
"deviceAutoDeleteProperties": {
    "deleteOn": false,
    "deleteAfterMinutes": 0,
    "retainWhileUploading": true
},
"deviceToCloudUploadProperties": {
    "uploadOn": true,
    "uploadOrder": "OldestFirst",
    "cloudStorageConnectionString": "<<my connection string was here :) >>",
    "storageContainersForUpload": {
        "eds-container-pcu": {
            "target": "eds-container-pcu"
        }
    },
    "deleteAfterUpload": true
}
}

iotedge列表上写着

blobstorage      running          Up 5 hours       mcr.microsoft.com/azure-blob-storage:latest

我还检查了音量。我把一个文件放到我的卷中的"BlockBlob“文件夹中，然后我进入容器的外壳，在/blobroot下我可以找到这个文件。

我还复制了云存储连接字符串，并将其用于文件上传，这也是有效的。我可以成功地将文本文件上传到我的云存储帐户中。

我的本地存储帐户的连接字符串应该是这样的，不是吗？我自己创建的，就像医生说的那样：

DefaultEndpointsProtocol=http;BlobEndpoint=http://localhost:11002/localstorage;AccountName=localstorage;AccountKey=92RhvUXR59Aa8h90LSHC7w==;

使用该连接字符串，我无法连接任何内容。不是SDK，也不是Storage Explorer。

Python代码将是：

    CONNECTION_STRING = "DefaultEndpointsProtocol=http;BlobEndpoint=http://localhost:11002/localstorage;AccountName=localstorage;AccountKey=92RhvUXR59Aa8h90LSHC7w==;"
    blobClient = BlobClient.from_connection_string(CONNECTION_STRING, "eds-container-pcu", "test123.txt")
    # Doesn't work with or without this line
    blobClient._X_MS_VERSION = '2017-04-17'
    blobClient.upload_blob(data="Hello World", blob_type="BlockBlob")

我得到了：

为什么会这样呢？存储资源管理器也没有连接，上面的代码行与我的云存储连接字符串一起工作得很好。

Answer 1

一位同事指出，我的本地账户密钥太短。正如文档中所写的，密钥的长度必须为64字节。那么与SDK或StorageExplorer的连接就可以了。我的代码也没有创建本地容器，但是错误消息会告诉你这一点。

Answer 2

在容器创建选项的示例中，我缺少键(LOCAL_STORAGE_ACCOUNT_NAME和LOCAL_STORAGE_ACCOUNT_KEY)。您是否仅指定了值？

"Env": [
    "LOCAL_STORAGE_ACCOUNT_NAME=localstorage",
    "LOCAL_STORAGE_ACCOUNT_KEY=92RhvUXR59Aa8h90LSHC7w=="
  ],

当我使用这些设置部署模块时，我可以通过Storage Explorer进行连接。

你看过blob存储模块的日志了吗？
