HTTPS

HTTPS is the HTTP protocol over TLS/SSL. In Node.js this is implemented as a separate module.

Class: https.Agent

An Agent object for HTTPS similar to http.Agent. See https.request() for more information.

Class: https.Server

This class is a subclass of tls.Server and emits events same as http.Server. See http.Server for more information.

server.close([callback])

• callback <Function>

See server.close() from the HTTP module for details.

server.listen()

Starts the HTTPS server listening for encrypted connections. This method is identical to server.listen() from net.Server.

server.setTimeout([msecs][, callback])

• msecs <number> Defaults to 120000 (2 minutes).
• callback <Function>

See http.Server#setTimeout().

server.timeout

• <number> Defaults to 120000 (2 minutes).

See http.Server#timeout.

server.keepAliveTimeout

• <number> Defaults to 5000 (5 seconds).

See http.Server#keepAliveTimeout.

https.createServer([options][, requestListener])

• options <Object> Accepts options from tls.createServer() and tls.createSecureContext().
• requestListener <Function> A listener to be added to the request event.

Example:

// curl -k https://localhost:8000/
const https = require('https');
const fs = require('fs');

const options = {
  key: fs.readFileSync('test/fixtures/keys/agent2-key.pem'),
  cert: fs.readFileSync('test/fixtures/keys/agent2-cert.pem')
};

https.createServer(options, (req, res) => {
  res.writeHead(200);
  res.end('hello world\n');
}).listen(8000);

Or

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

const options = {
  pfx: fs.readFileSync('test/fixtures/test_cert.pfx'),
  passphrase: 'sample'
};

https.createServer(options, (req, res) => {
  res.writeHead(200);
  res.end('hello world\n');
}).listen(8000);

https.get(options[, callback])

• options <Object> | <string> | <URL> Accepts the same options as https.request(), with the method always set to GET.
• callback <Function>

Like http.get() but for HTTPS.

options can be an object, a string, or a URL object. If options is a string, it is automatically parsed with url.parse(). If it is a URL object, it will be automatically converted to an ordinary options object.

Example:

const https = require('https');

https.get('https://encrypted.google.com/', (res) => {
  console.log('statusCode:', res.statusCode);
  console.log('headers:', res.headers);

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

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

https.globalAgent

Global instance of https.Agent for all HTTPS client requests.

https.request(options[, callback])

• options <Object> | <string> | <URL> Accepts all options from http.request(), with some differences in default values:
  • protocol Defaults to https:
  • port Defaults to 443.
  • agent Defaults to https.globalAgent.
• callback <Function>

Makes a request to a secure web server.

The following additional options from tls.connect() are also accepted when using a custom Agent: pfx, key, passphrase, cert, ca, ciphers, rejectUnauthorized, secureProtocol, servername

options can be an object, a string, or a URL object. If options is a string, it is automatically parsed with url.parse(). If it is a URL object, it will be automatically converted to an ordinary options object.

Example:

const https = require('https');

const options = {
  hostname: 'encrypted.google.com',
  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();

Example using options from tls.connect():

const options = {
  hostname: 'encrypted.google.com',
  port: 443,
  path: '/',
  method: 'GET',
  key: fs.readFileSync('test/fixtures/keys/agent2-key.pem'),
  cert: fs.readFileSync('test/fixtures/keys/agent2-cert.pem')
};
options.agent = new https.Agent(options);

const req = https.request(options, (res) => {
  // ...
});

Alternatively, opt out of connection pooling by not using an Agent.

Example:

const options = {
  hostname: 'encrypted.google.com',
  port: 443,
  path: '/',
  method: 'GET',
  key: fs.readFileSync('test/fixtures/keys/agent2-key.pem'),
  cert: fs.readFileSync('test/fixtures/keys/agent2-cert.pem'),
  agent: false
};

const req = https.request(options, (res) => {
  // ...
});

Example using a URL as options:

const { URL } = require('url');

const options = new URL('https://abc:[email protected]');

const req = https.request(options, (res) => {
  // ...
});
