Azure App Service - 403 Forbidden scenarios When Accessing Azure Storage Blob with SAS Token
I'm performance testing and I've been struggling with this for a few days now and could really use some help. I've looked through the documentation and I'm still confused about After trying multiple solutions online, I still can't figure this out..... This might be a silly question, but I'm working with a frustrating scenario with my Azure App Service when trying to access Azure Blob Storage using a Shared Access Signature (SAS) token. The setup involves an ASP.NET Core 6 application that should read files from a blob container, but I'm getting a `403 Forbidden` behavior when making the request to the blob. The code to generate the SAS token looks like this: ```csharp var storageAccount = CloudStorageAccount.Parse(connectionString); var blobClient = storageAccount.CreateCloudBlobClient(); var container = blobClient.GetContainerReference("mycontainer"); var blob = container.GetBlockBlobReference("myfile.txt"); var sharedAccessPolicy = new SharedAccessBlobPolicy { SharedAccessExpiryTime = DateTime.UtcNow.AddHours(1), Permissions = SharedAccessBlobPermissions.Read }; var sasToken = blob.GetSharedAccessSignature(sharedAccessPolicy); ``` When I try to access the blob using the generated SAS token like this: ```csharp var httpClient = new HttpClient(); httpClient.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Bearer", sasToken); var response = await httpClient.GetAsync("https://<storage-account-name>.blob.core.windows.net/mycontainer/myfile.txt"); ``` I receive a `403 Forbidden` response. I've confirmed that the storage account allows public access to the blob container, and I’ve double-checked that the SAS token is still valid. I've also ensured the correct permissions are set in the `SharedAccessBlobPermissions`. Additionally, I've tried regenerating the SAS token using different expiration times and permissions but still face the same scenario. I’ve verified that the blob exists and the connection string is correct. Is there something I'm missing in the configuration or permissions setup? Any insights on resolving this would be greatly appreciated! I'm working on a web app that needs to handle this. What's the best practice here? My development environment is Linux. Any help would be greatly appreciated! Is there a simpler solution I'm overlooking? The project is a service built with C#. Any pointers in the right direction? Thanks, I really appreciate it!
