Per-request auth / headers / request options

Describe the solution you’d like In server side rendering environments it is common that a single process may need to make requests on behalf of several users, each with their own set of credentials. It seems like this is doable with something like:

import { MyService, OpenAPI } from 'MyService'

OpenAPI.TOKEN = () => { OpenAPI.TOKEN = undefined; return 'abc123' }
MyService.someOperation({})

The issue is that the TOKEN needs to be set before each call in a bit of a clunky way, and if there the is anything async that happens between setting it and the request actually being sent off it’s possible for one request to incorrectly be made with credentials intended for another. Ideally I’d like to be able to pass credentials as a final argument any operation (this works better with the “useOptions” style). I’d also be OK with passing some kind of extension of ApiRequestOptions so that resolvers could work on a per-req basis, e.g.:

import { MyService, OpenAPI } from 'MyService'

OpenAPI.TOKEN = (opts) => opts.myCustomAuth
MyService.someOperation({}, { myCustomAuth: 'abc123' )

@Lanny I see, it makes sense

But I still think that global parameters are evil =) What I see is that two parts of the generated code might be split:

• fixed part core
• floating part models/services

in this case, core part might have a client which can be instantiated in order to have own token/url/etc. And models/services can accept the client as an argument and be just functions.

But the main problem I see is that these changes require a lot of effort, bring significant changes into library api and probably conflict with other functionality I don’t know about… =)

I definitely see the use case, there is also already a PR for this: PR: https://github.com/ferdikoomen/openapi-typescript-codegen/pull/822
