I am trying to make a request to the Azurite api from a cypress test. I understand I need an authentication header and I tried using a nodejs script to generate the header. I keep getting an Unauthorized error when I try to query a table. I am not using the default ports for azurite but I'm not sure how that would affect this.

Request (I'm using Postman):

curl --location 'http://localhost:10012/devstoreaccount1/AuditLogs' \
--header 'Date: Mon, 10 Mar 2025 09:49:14 GMT' \
--header 'x-ms-version: 2025-01-05' \
--header 'Authorization: SharedKey devstoreaccount1:ttvHEM3DX/mmZ6LIMHEMEbNbS0SrR1UD+DLv6ej8+Tk=' \
--header 'Accept: application/json;odata=nometadata'

Node script for generating the auth code

const crypto = require('crypto');

const accountName = 'devstoreaccount1';
const accountKey = 'Eby8vdM02xNOcqFlqUwJPLlmEtlCDXJ1OUzFT50uSRZ6IFsuFq2UVErCz4I6tq/K1SZFPTOtr/KBHBeksoGMGw==';
const tableName = 'AuditLogs';
const date = new Date().toUTCString(); // Must be present in the request

// Canonicalized resource format for Table Storage
const canonicalizedResource = `/${accountName}/${tableName}`;

// Correct string-to-sign format for Table Storage
const stringToSign = `GET\n\n\n${date}\n${canonicalizedResource}`;

// Compute HMAC-SHA256 signature using the account key
const key = Buffer.from(accountKey, 'base64');
const hmac = crypto.createHmac('sha256', key);
hmac.update(stringToSign);
const signature = hmac.digest('base64');

// Construct the Authorization header
const authorizationHeader = `SharedKey ${accountName}:${signature}`;

console.log(`Date: ${date}`); // Ensure this is set in the request
console.log(`Authorization: ${authorizationHeader}`);

How to authenticate azurite REST API table storage?

I agree with above Gaurav Mantri' answer you need to add the account name twice in the canonicalized resource name.

You can query tables and entities by following this Microsoft document.

In your code, I noticed that you are passing only the table name in your request. It should be <TableName>()

You can use the code below to query tables in an Azurite environment without needing Postman.

Code:

const axios = require('axios');
const crypto = require('crypto');

const storageAccountName = 'devstoreaccount1';
const storageKey = 'Eby8vdM02xNOcqFlqUwJPLlmEtlCDXJ1OUzFT50uSRZ6IFsuFq2UVErCz4I6tq/K1SZFPTOtr/KBHBeksoGMGw==';

const url = `http://127.0.0.1:10002/${storageAccountName}/table1()`; // table name with ()
const version = '2025-01-05'; // x-ms-version
const date = new Date().toUTCString();
const parameters = 'table1()';

const canonicalizedResources = `/${storageAccountName}/${storageAccountName}/${parameters}`;
const canonicalizedHeaders = `x-ms-date:${date}`;
const stringToSign = `${date}\n${canonicalizedResources}`;

const signature = crypto
    .createHmac('sha256', Buffer.from(storageKey, 'base64'))
    .update(stringToSign, 'utf8')
    .digest('base64');

const headers = {
    'x-ms-date': date,
    'x-ms-version': version,
    'Authorization': `SharedKeyLite ${storageAccountName}:${signature}`,
    'Accept': 'application/json;odata=nometadata'
};

axios.get(url, { headers })
    .then(response => {
        console.log(response.status, response.data);
    })
    .catch(error => {
        console.error(error.response ? error.response.data : error.message);
    });

Output:

200 {
  value: [
    {
      PartitionKey: 'Name',
      RowKey: 'MS Dhoni',
      property1: 'Captain',
      Timestamp: '2025-03-13T09:32:02.9141377Z'
    },
    {
      PartitionKey: 'sample',
      RowKey: 'test',
      property1: 'demo',
      Timestamp: '2025-03-13T09:31:43.0202460Z'
    }
  ]
}

Based on the documentation here, when connecting to Azurite, the account name must appear twice in the canonicalized resource name.

Please use the following code:

const canonicalizedResource = `/${accountName}/${accountName}/${tableName}`;

and that should solve the problem.

Here's my updated script that finally worked, thanks to your help! I had to put the account name twice in the resources, add parentheses to the table name and update the stringToSign a bit, I had the word GET which was unnecessary.

const crypto = require('crypto');

const accountName = 'devstoreaccount1';
const accountKey = 'Eby8vdM02xNOcqFlqUwJPLlmEtlCDXJ1OUzFT50uSRZ6IFsuFq2UVErCz4I6tq/K1SZFPTOtr/KBHBeksoGMGw==';
const tableName = 'AuditLogs()';
const date = new Date().toUTCString();

const canonicalizedResource = `/${accountName}/${accountName}/${tableName}`;

const stringToSign = `${date}\n${canonicalizedResource}`;

const signature = crypto
    .createHmac('sha256', Buffer.from(accountKey, 'base64'))
    .update(stringToSign, 'utf8')
    .digest('base64');

const authorizationHeader = `SharedKeyLite ${accountName}:${signature}`;

console.log(`Date: ${date}`);
console.log(`Authorization: ${authorizationHeader}`);
