Unable to Retrieve Snapshot from Dahua DVR API - 401 Unauthorized

[roni9843]

Dahua DVR Snapshot Issue

Description

I am trying to capture a snapshot from my Dahua DVR using a Node.js project, but I am encountering a 401 Unauthorized error despite using the correct credentials.

Project Details

I am using Node.js with Axios to send requests to the Dahua DVR API. The goal is to retrieve a snapshot from the DVR.

API Endpoint

http://admin:[email protected]/cgi-bin/snapshot.cgi?channel=1

When accessed via a browser, the URL prompts for credentials and works as expected. However, in my Node.js application, it returns a 401 Unauthorized error.

Current Behavior

Receiving a 401 Unauthorized error when sending a GET request to the API using Axios in Node.js.

Node.js Code

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

const url = "http://admin:[email protected]/cgi-bin/snapshot.cgi?channel=1";

axios({
  method: 'get',
  url: url,
  responseType: 'stream',
  auth: {
    username: 'admin',
    password: 'abc12345'
  }
})
.then(response => {
  response.data.pipe(fs.createWriteStream('snapshot.jpg'));
  console.log("Snapshot saved as snapshot.jpg");
})
.catch(error => {
  console.log("Error:", error.message);
});

Troubleshooting Steps Taken

• Verified credentials by logging in via the browser.
• Ensured that the DVR’s HTTP Authentication settings are correctly configured.
• Attempted using both Basic Authentication and Digest Authentication.
• Checked the Security settings on the DVR but could not find specific HTTP Authentication options.
• Verified that the API endpoint works directly in the browser but fails in Node.js.

Expected Behavior

The API should return a snapshot image without authentication errors when accessed via Node.js.
