指定的资源名称长度不在允许的范围内 Azure Blob 存储

Question

当我尝试将 blob 上传到我的Azure Storage Account.

下面是我的代码。

private async Task UploadToAzureBlobStorage(string path, string fileName) {
    try {
        if (CloudStorageAccount.TryParse(StorageConnectionString, out CloudStorageAccount cloudStorageAccount)) {
            var cloudBlobClient = cloudStorageAccount.CreateCloudBlobClient();
            var cloudBlobContainer = cloudBlobClient.GetContainerReference(path);
            var cloudBlockBlob = cloudBlobContainer.GetBlockBlobReference(fileName);
            await cloudBlockBlob.UploadFromFileAsync(path);
        }
        else {
            throw new CustomConfigurationException(CustomConstants.NoStorageConnectionStringSettings);
        }
    }
    catch(Exception ex) {
        throw new CustomConfigurationException($ "Error when uploading to blob: {ex.Message}");
    }
}

还有其他人遇到过同样的问题吗？

有时，错误消息可能具有误导性。我在调用 时遇到了这个错误，await cloudBlockBlob.UploadFromFileAsync(path);这个问题背后的原因是，我为函数提供了一个无效的参数cloudBlobClient.GetContainerReference(path);

这是因为最近的发展变化。我一直专注于函数中的fileName参数GetBlockBlobReference，因为我认为问题出在 blob 名称上。

不幸的是我错了，真正的问题是blob container name它有一些特殊字符，所以我schedule在现有函数中引入了一个新参数，这个参数的值可以是每天、每周、每月，这些是我在 Azure Blob 存储中配置的容器。

private async Task UploadToAzureBlobStorage(string schedule, string path, string fileName) {
    try {
        if (CloudStorageAccount.TryParse(StorageConnectionString, out CloudStorageAccount cloudStorageAccount)) {
            var cloudBlobClient = cloudStorageAccount.CreateCloudBlobClient();
            var cloudBlobContainer = cloudBlobClient.GetContainerReference(schedule);
            var cloudBlockBlob = cloudBlobContainer.GetBlockBlobReference(fileName);
            await cloudBlockBlob.UploadFromFileAsync(path);
        }
        else {
            throw new CustomConfigurationException(CustomConstants.NoStorageConnectionStringSettings);
        }
    }
    catch(Exception ex) {
        throw new CustomConfigurationException($ "Error when uploading to blob: {ex.Message}");
    }
}
