#WRITING SAS CODE CODE#
Strategyīefore we start migrating our existing code to start using SAS we need to go over our strategy to solve this problem. The only difference is the value of the connection property as it will be a limited access connection string based on rules your code defines. Once you start using SAS as your connection string this code does not change. This is a basic example of uploading files to Blob Storage. String connection = "CONNECTION_STRING_TO_STORAGE īlobServiceClient client = new BlobServiceClient(connection) īlobContainerClient container = await client.CreateBlobContainerAsync("my-container") īlobClient blob = contianer.GetBlockBlobReference("file-name") Īwait blob.UploadFromStreamAsync(stream)
An upload statement might look like the code snippet below
NET Ecosystem you use the SDK that provides wrappers around all of the HTTP calls which makes it simple to interact with the Storage Account. When working with Azure Blob Storage in the. Whenever you have security discussions it is important to discuss your risk and security benefits to best determine how much security is needed. That doesn't mean it will be perfect, and hackers won't be able to attack your resources. If you implement this solution exactly how I have it here, your system will be more secure.
#WRITING SAS CODE SOFTWARE#
I am a software developer first and any security best practices I recommend are just my opinions. To continue with good security practices it is important to that the SAS is returned to the client only using a secure connection via TLS or other secure transport technology. The client can now make the necessary requests to the Azure Resource. To implement this solution securely I have created a backend that provides a unique access token known as a Shared Access Signature (SAS) which shares that with the client. This would create a massive security hole where a bad actor could hijack the Azure Resource.
These files need to be uploaded by the client, but the client app should NEVER store the connection string or secrets of the Azure Resource. I am currently building a Universal Windows Platform (UWP) application that needs to upload files to an Azure Blob Storage resource.
#WRITING SAS CODE HOW TO#
In this article we will go over how to architect a client side applicaiton and backend service to securely use a Shared Access Signature (SAS) using a real world example Real World Example This removes any need to share an all access connection string saved on a client app that can be hijacked by a bad actor. A real world example would be to retrieve a Shared Access Signature on a mobile, desktop or any client side app to process the functions. Shared Access Signature (SAS) provides a secure way to upload and download files from Azure Blob Storage without sharing the connection string.

The link you provide seems to indicate you would need to create a tasks.json, but it might be good looking at some other language implementations for ideas. I never implemented the idea you have, so I do not know what the recommendation would be.
You will probably need to work in a branch/fork and load that version in your local VS code to see what works. Subject: Re: Executing the SAS code in VS Code ( #3) To: VaccineAndDrugEvaluationCentre/vscode-sas-language
