Snapshot - 401 unauthorized

[Wade-BuildOtto]

Has anyone solved the issue when requesting a snapshot with various methods of passing in username and password, I get a 401 unauthorized, even going to the url for the cgi and filling in the popup it just ask over and over again.

There is an example of this in the ONVIF-AUDIT project here on github. ONVIF-AUDIT Project

You need to make a HTTP request with Digest Authentication.

I've cut this down from the original source, so mayhave introdced a typo. But you'll get the idea.

                            cam_obj.getSnapshotUri({ profileToken: videoSource.profileToken }, function (err, getUri_result) {

                                if (!err && getUri_result) {

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

                                    let filename = ""pic.jpg";
                                    let uri = url.parse(getUri_result.uri);

                                    let digestRequest = require('request-digest')(username, password);
                                    digestRequest.request({
                                        host: 'http://' + uri.host,
                                        path: uri.path,
                                        port: uri.port,
                                        encoding: null, // return data as a Buffer()
                                        method: 'GET'
                                    }, function (error, response, body) {
                                        if (error) {
                                            // console.log('Error downloading snapshot');
                                            // throw error;
                                        } else {

                                            fs.open(filename, 'w', function (err) {
                                                // callback for file opened, or file open error
                                                if (err) {
                                                    console.log('ERROR - cannot create output log file');
                                                }
                                                fs.appendFile(filename, body, function (err) {
                                                    if (err) {
                                                        console.log('Error writing to file');
                                                    }
                                                });

                                            });
                                        }
                                    });
