NestJS：护照 LinkedIn 策略与 graphql

Question

I have nestjs application running on typescript, Graphql, Postgres with Jwt strategy defined, now I need to workout LinkedIn strategy with it. I am not really sure where to start with it, there are a couple of packages available but they are missing the Graphql part and they are mostly pointing to API endpoints on local like /auth/linkedin/callback , I would like to know here and how to start.

Answer 1

If you look at LinkedIn's OAuth documentatioin you'll see that LinkedIn needs to know about a callback url for when authorization attempts are successful. You'll also see that the response for the initial authroization call (what calls your callback URL) is a GET request that doesn't conform to GraphQL format, so you have to implement a REST endpoint for this.

This is pretty true for most OAuth2.0 calls. You need to implement them in REST, not GraphQL. If you really wanted to, you could take the REST call and do some transformation to make it a GQL call, then forward it on to your GQL server, but that's still a REST endpoint you've got in your server.
