function request
Usage in Deno
import { request } from "node:https";
request(options: ,callback?: (res: http.IncomingMessage) => void,): http.ClientRequest
Makes a request to a secure web server.
The following additional options from tls.connect() are also accepted: ca, cert, ciphers, clientCertEngine, crl, dhparam, ecdhCurve, honorCipherOrder, key, passphrase,
pfx, rejectUnauthorized, secureOptions, secureProtocol, servername, sessionIdContext, highWaterMark.
options can be an object, a string, or a URL object. If options is a
string, it is automatically parsed with new URL(). If it is a URL object, it will be automatically converted to an ordinary options object.
https.request() returns an instance of the http.ClientRequest class. The ClientRequest instance is a writable stream. If one needs to
upload a file with a POST request, then write to the ClientRequest object.
import https from 'node: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.
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 options = new URL('https://abc:xyz@example.com');
const req = https.request(options, (res) => {
// ...
});
Example pinning on certificate fingerprint, or the public key (similar topin-sha256):
import tls from 'node:tls';
import https from 'node:https';
import crypto from 'node:crypto';
function sha256(s) {
return crypto.createHash('sha256').update(s).digest('base64');
}
const options = {
hostname: 'github.com',
port: 443,
path: '/',
method: 'GET',
checkServerIdentity: function(host, cert) {
// Make sure the certificate is issued to the host we are connected to
const err = tls.checkServerIdentity(host, cert);
if (err) {
return err;
}
// Pin the public key, similar to HPKP pin-sha256 pinning
const pubkey256 = 'pL1+qb9HTMRZJmuC/bB/ZI9d302BYrrqiVuRyW+DGrU=';
if (sha256(cert.pubkey) !== pubkey256) {
const msg = 'Certificate verification error: ' +
`The public key of '${cert.subject.CN}' ` +
'does not match our pinned fingerprint';
return new Error(msg);
}
// Pin the exact certificate, rather than the pub key
const cert256 = '25:FE:39:32:D9:63:8C:8A:FC:A1:9A:29:87:' +
'D8:3E:4C:1D:98:DB:71:E4:1A:48:03:98:EA:22:6A:BD:8B:93:16';
if (cert.fingerprint256 !== cert256) {
const msg = 'Certificate verification error: ' +
`The certificate of '${cert.subject.CN}' ` +
'does not match our pinned fingerprint';
return new Error(msg);
}
// This loop is informational only.
// Print the certificate and public key fingerprints of all certs in the
// chain. Its common to pin the public key of the issuer on the public
// internet, while pinning the public key of the service in sensitive
// environments.
do {
console.log('Subject Common Name:', cert.subject.CN);
console.log(' Certificate SHA256 fingerprint:', cert.fingerprint256);
hash = crypto.createHash('sha256');
console.log(' Public key ping-sha256:', sha256(cert.pubkey));
lastprint256 = cert.fingerprint256;
cert = cert.issuerCertificate;
} while (cert.fingerprint256 !== lastprint256);
},
};
options.agent = new https.Agent(options);
const req = https.request(options, (res) => {
console.log('All OK. Server matched our pinned cert or public key');
console.log('statusCode:', res.statusCode);
// Print the HPKP values
console.log('headers:', res.headers['public-key-pins']);
res.on('data', (d) => {});
});
req.on('error', (e) => {
console.error(e.message);
});
req.end();
