# HTTPS#

    Stability: 3 - Stable

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

## 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.setTimeout(msecs, callback)#

See http.Server#setTimeout().

### server.timeout#

See http.Server#timeout.

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

Returns a new HTTPS web server object. The `options` is similar to tls.createServer(). The `requestListener` is a function which is automatically added to the `'request'` event.

Example:

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

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

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

Or

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

    var options = {
      pfx: fs.readFileSync('server.pfx')
    };

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

### server.listen(port[, host][, backlog][, callback])#

### server.listen(path[, callback])#

### server.listen(handle[, callback])#

See http.listen() for details.

### server.close([callback])#

See http.close() for details.

## https.request(options, callback)#

Makes a request to a secure web server.

`options` can be an object or a string. If `options` is a string, it is automatically parsed with url.parse().

All options from http.request() are valid.

Example:

    var https = require('https');

    var options = {
      hostname: 'encrypted.google.com',
      port: 443,
      path: '/',
      method: 'GET'
    };

    var req = https.request(options, function(res) {
      console.log("statusCode: ", res.statusCode);
      console.log("headers: ", res.headers);

      res.on('data', function(d) {
        process.stdout.write(d);
      });
    });
    req.end();

    req.on('error', function(e) {
      console.error(e);
    });

The options argument has the following options

- `host`: A domain name or IP address of the server to issue the request to. Defaults to `'localhost'`.
- `hostname`: To support `url.parse()` `hostname` is preferred over `host`
- `port`: Port of remote server. Defaults to 443.
- `method`: A string specifying the HTTP request method. Defaults to `'GET'`.
- `path`: Request path. Defaults to `'/'`. Should include query string if any. E.G. `'/index.html?page=12'`
- `headers`: An object containing request headers.
- `auth`: Basic authentication i.e. `'user:password'` to compute an Authorization header.
- `agent`: Controls Agent behavior. When an Agent is used request will default to `Connection: keep-alive`. Possible values:
  - `undefined` (default): use globalAgent for this host and port.
  - `Agent` object: explicitly use the passed in `Agent`.
  - `false`: opts out of connection pooling with an Agent, defaults request to `Connection: close`.

The following options from tls.connect() can also be specified. However, a globalAgent silently ignores these.

- `pfx`: Certificate, Private key and CA certificates to use for SSL. Default `null`.
- `key`: Private key to use for SSL. Default `null`.
- `passphrase`: A string of passphrase for the private key or pfx. Default `null`.
- `cert`: Public x509 certificate to use. Default `null`.
- `ca`: An authority certificate or array of authority certificates to check the remote host against.
- `ciphers`: A string describing the ciphers to use or exclude. Consult http://www.openssl.org/docs/apps/ciphers.html#CIPHER_LIST_FORMAT for details on the format.
- `rejectUnauthorized`: If `true`, the server certificate is verified against the list of supplied CAs. An `'error'` event is emitted if verification fails. Verification happens at the connection level, before the HTTP request is sent. Default `true`.
- `secureProtocol`: The SSL method to use, e.g. `TLSv1_method` to force TLS version 1. The possible values depend on your installation of OpenSSL and are defined in the constant SSL_METHODS.

In order to specify these options, use a custom `Agent`.

Example:

    var 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);

    var req = https.request(options, function(res) {
      ...
    }

Or does not use an `Agent`.

Example:

    var 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
    };

    var req = https.request(options, function(res) {
      ...
    }

## https.get(options, callback)#

Like `http.get()` but for HTTPS.

`options` can be an object or a string. If `options` is a string, it is automatically parsed with url.parse().

Example:

    var https = require('https');

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

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

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

## Class: https.Agent#

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

## https.globalAgent#

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