Unable to verify the first certificate

[yohanntran]

Hi everyone,

I use node-ews to send message with ExchangeWeb Service but i have a problem. When i use my 4G i can send message (because certificate is allow by default) But i when i want use the network of my company, i can't. I read this error (unable to verify the first certificate).

I search and i found some solution like that : process.env.NODE_TLS_REJECT_UNAUTHORIZED = '0'; but it's a ungly solution. I want solve the problem properly. I have the certificate of my company in .crt.

My question : Do you have implemente a function to pass in parameter the certificate ? or do you have an other solution ?

I'm French, sorry for my french expression. Thank to developpe this library, it's very helpfull.

Hi everyone,

I find a solution which seems good but it's don't work. I try to do that in shell : export NODE_EXTRA_CA_CERTS=["xxxx/xxxx.crt"]

but : $ node index.js Warning: Ignoring extra certs from [xxxx/xxxx.crt], load failed: error:0200107B:system library:fopen:Unknown error app is running

I find the solution.

My problem : The certificate was wrong. You should go to the good website and download the certificate like that : https://medium.com/@menakajain/export-download-ssl-certificate-from-server-site-url-bcfc41ea46a2

After, you should enter in shell : NODE_EXTRA_CA_CERTS="C:/xxxx.pem" without export term with a great link (no relative to start and safety)

Normaly, the probleme is solve.

But you can try that if it's not the case in the code .js: const https = require('https'); const fs = require('fs');

const trustedCa = [ 'C:/xxxx.pem' ];

https.globalAgent.options.ca = []; for (const ca of trustedCa) { https.globalAgent.options.ca.push(fs.readFileSync(ca)); }

or in the shell command npm config set cafile "path-to-my-cert.pem" npm config ls -l

and you can test the connexion with (in the code .js): const https = require('https'); const options = { hostname: 'web_site_link', port: 443, path: '/', method: 'GET' };

const req = https.request(options, (res) => { console.log('statusCode:', res.statusCode); console.log('headers:', res.headers);

res.on('data', (d) => { process.stdout.write(d); }); });

req.on('error', (e) => { console.error(e); }); req.end();
