<!-- YAML
added: v0.3.6
changes:
- version: v7.5.0
pr-url: https://github.com/nodejs/node/pull/10638
description: The `options` parameter can be a WHATWG `URL` object.
-->
- `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}
向一个安全的服务器发起一个请求。
The following additional `options` from [`tls.connect()`][] are also accepted when using a
custom [`Agent`][]:
`pfx`, `key`, `passphrase`, `cert`, `ca`, `ciphers`, `rejectUnauthorized`, `secureProtocol`, `servername`
参数 `options` 可以是一个对象、或字符串、或 [`URL`] 对象。
如果参数 `options` 是一个字符串, 它自动被 [`url.parse()`] 所解析。
If it is a [`URL`][] object, it will be automatically converted to an ordinary `options` object.
例子:
```js
const https = require('https');
const options = {
hostname: 'encrypted.google.com',
port: 443,
path: '/',
method: 'GET'
};
const req = https.request(options, (res) => {
console.log('状态码：', res.statusCode);
console.log('请求头：', 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()`][]:
```js
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) => {
// ...
});
```
也可以不对连接池使用 `Agent`。
例子:
```js
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`:
```js
const { URL } = require('url');
const options = new URL('https://abc:xyz@example.com');
const req = https.request(options, (res) => {
// ...
});
```
