[Storage] JS does not support all connection strings supported by .NET

[mikeharder]

The following connection string works in the latest builds of both .NET and JS:

DefaultEndpointsProtocol=http;AccountName=devstoreaccount1;
AccountKey=Eby8vdM02xNOcqFlqUwJPLlmEtlCDXJ1OUzFT50uSRZ6IFsuFq2UVErCz4I6tq/K1SZFPTOtr/KBHBeksoGMGw==;
BlobEndpoint=http://127.0.0.1:10000/devstoreaccount1;
TableEndpoint=http://127.0.0.1:10002/devstoreaccount1;
QueueEndpoint=http://127.0.0.1:10001/devstoreaccount1;

However, if this is reduced to a more minimal connection string:

BlobEndpoint=http://127.0.0.1:10000/devstoreaccount1;

It still works in .NET (you can verify with an HTTP debugger like Fiddler), but it fails in JS with:

Invalid SharedAccessSignature in the provided SAS Connection String

It appears the JS SDK is more strict about connection string parsing than the .NET SDK. I'm not sure which is more correct or how important this is, but ideally the SDKs would be consistent across languages.

Thanks, Mike.
Currently, JS SDK expects DefaultEndpointsProtocol and AccountKey to be present in an Account Connection String.

https://docs.microsoft.com/en-us/azure/storage/common/storage-configure-connection-string#configure-a-connection-string-for-an-azure-storage-account

And the Development Connection String support is currently being added - #5004

We need to have a discussion and decide which fields are mandatory.

@XiaoningLiu do you know where we can find a specification for all the formats of supported connection strings?

Just like the doc link Harsha pasted https://docs.microsoft.com/en-us/azure/storage/common/storage-configure-connection-string#configure-a-connection-string-for-an-azure-storage-account

[jeremymeng]

I couldn't find any spec on the minimal format

BlobEndpoint=http://127.0.0.1:10000/devstoreaccount1;

[HarshaNalluru]

@XiaoningLiu, please add support for more kinds of connection strings if required, to be in sync with the .NET sdk.

[XiaoningLiu]

If a connection string doesn't mentioned in the doc, it should not be a official standard.

BlobEndpoint=http://127.0.0.1:10000/devstoreaccount1; doesn't include required account name, at least account key, which cannot make it a compelete connection string.

@XiaoningLiu Are there any planned next steps here? If not, then can we close this issue?

[XiaoningLiu]

I think we can close this. JS already supports short cut connection string for emulator account UseDevelopmentStorage=true.
