Ignore invalid self-signed ssl certificate in node.js with https.request?

Cheap and insecure answer:

Add

process.env["NODE_TLS_REJECT_UNAUTHORIZED"] = 0;

in code, before calling https.request()

A more secure way (the solution above makes the whole node process insecure) is answered in this question

In your request options, try including the following:

   var req = https.request({ 
      host: '192.168.1.1', 
      port: 443,
      path: '/',
      method: 'GET',
      rejectUnauthorized: false,
      requestCert: true,
      agent: false
    },

Don't believe all those who try to mislead you.

In your request, just add:

ca: [fs.readFileSync([certificate path], {encoding: 'utf-8'})]

If you turn on unauthorized certificates, you will not be protected at all (exposed to MITM for not validating identity), and working without SSL won't be a big difference. The solution is to specify the CA certificate that you expect as shown in the next snippet. Make sure that the common name of the certificate is identical to the address you called in the request(As specified in the host):

What you will get then is:

var req = https.request({ 
      host: '192.168.1.1', 
      port: 443,
      path: '/',
      ca: [fs.readFileSync([certificate path], {encoding: 'utf-8'})],
      method: 'GET',
      rejectUnauthorized: true,
      requestCert: true,
      agent: false
    },

• How to generate CA Certs for testing easily in order to simulate production environment

Add the following environment variable:

NODE_TLS_REJECT_UNAUTHORIZED=0

e.g. with export:

export NODE_TLS_REJECT_UNAUTHORIZED=0
