|
> Query and modify a session's cookies.
|
|
|
|
Process: [Main](../glossary.md#main-process)
|
|
|
|
Instances of the `Cookies` class are accessed by using `cookies` property of
|
|
a `Session`.
|
|
|
|
For example:
|
|
|
|
```javascript
|
|
const {session} = require('electron')
|
|
|
|
// Query all cookies.
|
|
session.defaultSession.cookies.get({}, (error, cookies) => {
|
|
console.log(error, cookies)
|
|
})
|
|
|
|
// Query all cookies associated with a specific url.
|
|
session.defaultSession.cookies.get({url: 'http://www.github.com'}, (error, cookies) => {
|
|
console.log(error, cookies)
|
|
})
|
|
|
|
// Set a cookie with the given cookie data;
|
|
// may overwrite equivalent cookies if they exist.
|
|
const cookie = {url: 'http://www.github.com', name: 'dummy_name', value: 'dummy'}
|
|
session.defaultSession.cookies.set(cookie, (error) => {
|
|
if (error) console.error(error)
|
|
})
|
|
```
|
|
|
|
