/**
|
|
* **Options**
|
|
*
|
|
* - `cookies` - An `Array` of cookie names
|
|
* - `headers` - An `Array` of header names
|
|
* - `params` - An `Array` of param names
|
|
* - `model` - Specify an AccessToken class to use
|
|
*
|
|
* Each array is used to add additional keys to find an `accessToken` for a `request`.
|
|
*
|
|
* The following example illustrates how to check for an `accessToken` in a custom cookie, query string parameter
|
|
* and header called `foo-auth`.
|
|
*
|
|
* ```js
|
|
* app.use(loopback.token({
|
|
* cookies: ['foo-auth'],
|
|
* headers: ['foo-auth', 'X-Foo-Auth'],
|
|
* cookies: ['foo-auth', 'foo_auth']
|
|
* }));
|
|
* ```
|
|
*
|
|
* **Defaults**
|
|
*
|
|
* By default the following names will be checked. These names are appended to any optional names. They will always
|
|
* be checked, but any names specified will be checked first.
|
|
*
|
|
* - **access_token**
|
|
* - **X-Access-Token**
|
|
* - **authorization**
|
|
* - **access_token**
|
|
*
|
|
* **NOTE:** The `loopback.token()` middleware will only check for [signed cookies](http://expressjs.com/api.html#req.signedCookies).
|
|
*
|
|
* @header loopback.token(options)
