Google OAuth Setup (to send mails)
|
||||||
|
==================================
|
||||||
|
|
||||||
|
|
||||||
|
- Login @ https://console.cloud.google.com
|
||||||
|
|
||||||
|
- GMail API akivieren: https://console.cloud.google.com/apis/library/gmail.googleapis.com?
|
||||||
|
|
||||||
|
- Create new Project (aka 'BackendMailAPI') @ https://console.cloud.google.com/projectcreate
|
||||||
|
User Type: Intern
|
||||||
|
Anwendungsname: 'BackendMailAPI'
|
||||||
|
Support-Email: ...
|
||||||
|
Authorisierte Domains: 'heydyno.de' (or project domain)
|
||||||
|
Kontakt-Email: ...
|
||||||
|
|
||||||
|
|
||||||
|
- Unter "Anmeldedaten" neuer OAuth Client erstellen @ https://console.cloud.google.com/apis/credentials
|
||||||
|
Anwendungstyp: Web
|
||||||
|
Name: 'BackendMailOAuth'
|
||||||
|
Redirect-Uri: 'http://localhost/oauth'
|
||||||
|
Client-ID und Client-Key merken
|
||||||
|
|
||||||
|
- Open in Browser:
|
||||||
|
https://accounts.google.com/o/oauth2/v2/auth?redirect_uri=http://localhost/oauth&prompt=consent&response_type=code&client_id={...}&scope=https://www.googleapis.com/auth/gmail.send&access_type=offline
|
||||||
|
Code aus redirected URI merken
|
||||||
|
|
||||||
|
- Code via request einlösen (und refresh_roken merken):
|
||||||
|
|
||||||
|
```
|
||||||
|
curl --request POST \
|
||||||
|
--url https://oauth2.googleapis.com/token \
|
||||||
|
--data code={...} \
|
||||||
|
--data redirect_uri=http://localhost/oauth \
|
||||||
|
--data client_id={...} \
|
||||||
|
--data client_secret={...} \
|
||||||
|
--data grant_type=authorization_code \
|
||||||
|
--data scope=https://www.googleapis.com/auth/gmail.send
|
||||||
|
```
|
||||||
|
|
||||||
|
- Fertig, mit `client_id`, `client_secret` und `refresh_token` kann das package benutzt werden
