Error while creating azure blob SAS token from react app "Value for one of the query parameters specified in the request URI is invalid"

Question

I am trying to create a sas token from react app

async function GenerateSASToken() {
    const sasUrl = `https://${accountname}.blob.core.windows.net?sv=2021-06-08&ss=bfqt&srt=sco&sp=rwdlacupiytfx&se=2023-02-20T16:01:34Z&st=2023-02-20T08:01:34Z&spr=https&sig=<signinkey>`;
    axios.get(sasUrl)
        .then(response => {
            console.log(response.data);
            console.log('SUCCESS');
        })
        .catch(error => {
            console.log('FAIL');
            console.error(error);
        });
}

But I am getting error while calling endpoint as

400 (Value for one of the query parameters specified in the request URI is invalid.)

Answer 1

The reason you are getting this error is because you are using incorrect URL.

If you want to download a blob, the URL should be something like https://${accountname}.blob.core.windows.net/<container-name>/<blob-name>?sv=2021-06-08&ss=bfqt&srt=sco&sp=rwdlacupiytfx&se=2023-02-20T16:01:34Z&st=2023-02-20T08:01:34Z&spr=https&sig=<signinkey>.

The URL you are using corresponds to Get Account Information which requires restype=account&comp=properties URL parameters. Since you are not including these parameters in your URL, you are getting 400 error.

UPDATE

If you are trying to generate a new SAS token, please note that:

• There is no REST API endpoint to generate an Account or Service SAS token. Please read the documentation here about how you can generate a SAS token: https://learn.microsoft.com/en-us/rest/api/storageservices/delegate-access-with-shared-access-signature.
• You cannot generate a new SAS token using another SAS token.
