操作

参考：https://www.npmjs.com/package/js-cookie

Create a cookie, valid across the entire site:

Cookies.set('name', 'value');

Create a cookie that expires 7 days from now, valid across the entire site:

Cookies.set('name', 'value', { expires: 7 });

Create an expiring cookie, valid to the path of the current page:

Cookies.set('name', 'value', { expires: 7, path: '' });

Read cookie:

Cookies.get('name'); // => 'value'
Cookies.get('nothing'); // => undefined

Read all visible cookies:

Cookies.get(); // => { name: 'value' }

Note: It is not possible to read a particular cookie by passing one of the cookie attributes (which may or may not have been used when writing the cookie in question):

Cookies.get('foo', { domain: 'sub.example.com' }); // `domain` won't have any effect...!

The cookie with the name foo will only be available on .get() if it’s visible from where the code is called; the domain and/or path attribute will not have an effect when reading.

Delete cookie:

Cookies.remove('name');

Delete a cookie valid to the path of the current page:

Cookies.set('name', 'value', { path: '' });
Cookies.remove('name'); // fail!
Cookies.remove('name', { path: '' }); // removed!

IMPORTANT! When deleting a cookie and you’re not relying on the default attributes, you must pass the exact same path and domain attributes that were used to set the cookie:

Cookies.remove('name', { path: '', domain: '.yourdomain.com' });

Note: Removing a nonexistent cookie does not raise any exception nor return any value.
