指定的资源名称长度不在 Azure Blob 存储允许的限制内

当我尝试将 blob 上传到我的网站时，收到错误消息“指定的资源名称长度不在允许的范围内”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}");
    }
}

其他人也遇到过同样的问题吗？

有时错误消息可能会产生误导。当我调用时，我收到此错误await cloudBlockBlob.UploadFromFileAsync(path);这个问题背后的原因是，我向函数提供了无效的参数cloudBlobClient.GetContainerReference(path);

发生这种情况是因为最近的开发发生了变化。我一直专注于fileName中的参数GetBlockBlobReference函数，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其中有一些特殊字符，所以我引入了一个新参数schedule到现有函数，该参数的值可以是每日、每周、每月，这些是我在 Azure Blob 存储中配置的容器的名称。

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}");
    }
}
