c# - 指定的容器不存在(Azure)

Question

下面的代码有效。但是当我尝试从容器中删除 blob 时，我收到异常“指定的容器不存在”:

public static async Task Run([BlobTrigger("files-for-uploading/{name}", Connection = "AzureWebJobsStorage")]
        Stream myBlob, string name, ILogger log)
{
    try
    {
        var config = new ConfigurationBuilder()
            .AddJsonFile("local.settings.json", optional: true, reloadOnChange: true)
            .AddEnvironmentVariables()
            .Build();

        if (CloudStorageAccount.TryParse(config["AzureWebJobsStorage"],
            out CloudStorageAccount storageAccount))
        {
            ClientHandler clientHandler = new ClientHandler(HttpClientFactory.Create());
            CloudBlobClient blobClient = storageAccount.CreateCloudBlobClient();
            CloudBlobContainer container = 
            blobClient.GetContainerReference(config["ContainerForFileUploading"]);
            DeleteFilesFromBlob(container, name, log);
        }
    }
    catch (Exception e)
    {
        throw;
    }
}

删除功能:

private static void DeleteFilesFromBlob(CloudBlobContainer container, string blobName, ILogger log)
{
    CloudBlob file = container.GetBlobReference(blobName);
    file.DeleteIfExists();
}

当我在 Visual Studio 中运行它时，它删除工作，但在 azure 中不起作用。很奇怪。

GetBlobReference 的参数应该是 blob 的名称，而不是 fileUrl。

以下代码是我自己使用的，它可以工作。

    public async Task<IActionResult> delete(string blobName)
    {
        string blobstorageconnection = _configuration.GetValue<string>("blobstorage");
        string blobContainer = _configuration.GetValue<string>("blobcontainer");

        CloudStorageAccount cloudStorageAccount = CloudStorageAccount.Parse(blobstorageconnection);
        CloudBlobClient cloudBlobClient = cloudStorageAccount.CreateCloudBlobClient();

        CloudBlobContainer cloudBlobContainer = cloudBlobClient.GetContainerReference(blobContainer);
        var blob = cloudBlobContainer.GetBlobReference(blobName);
        await blob.DeleteIfExistsAsync();



        return View();
    }
