# Session From Token Middleware
|
||
|
|
|
||
|
|
Middleware to handle generating sessions from tokens, for example like with magic links, or SSO flows similar to SAML.
|
||
|
|
|
||
|
|
## Usage
|
||
|
|
|
||
|
|
```js
|
||
|
|
const sessionFromTokenMiddleware = require('@tryghost/mw-session-from-token')({
|
||
|
|
callNextWithError: true,
|
||
|
|
async createSession(req, res, user) {
|
||
|
|
req.session.user_id = user.id;
|
||
|
|
},
|
||
|
|
async getTokenFromRequest(res) {
|
||
|
|
return req.headers['some-cool-header'];
|
||
|
|
},
|
||
|
|
async getLookupFromToken(token) {
|
||
|
|
await someTokenService.validate(token);
|
||
|
|
const data = await someTokenService.getData(token);
|
||
|
|
return data.email;
|
||
|
|
},
|
||
|
|
async findUserByLookup(lookup) {
|
||
|
|
return await someUserModel.findOne({email: lookup});
|
||
|
|
}
|
||
|
|
});
|
||
|
|
|
||
|
|
someExpressApp.get('/some/sso/url', someSessionMiddleware, sessionFromTokenMiddleware, (req, res, next) => {
|
||
|
|
res.redirect('/loggedin');
|
||
|
|
}, (err, res, res, next) => {
|
||
|
|
res.redirect('/error');
|
||
|
|
});
|
||
|
|
```
