将用户存储在上下文中还是其他地方？

Question

I am having a hard time finding out if I am thinking about things in the best way. I want to know what to do with a user after they have been authenticated through some type of middleware, either BasicAuth or JWT.

Should I store all the relevant user fields in the context as a value? If I store them in the context then do I need a special function to pull them out? (which would use a user defined contextKey type to retrieve and convert its type back to the proper struct)

I can come up with something that works, but IDK if it is the most reasonable way to go about it.

Answer 1

Yes, context.Context is specifically for request scoped variables, among other things. (Notice, per request, so not suitable for storing data you mean to access between requests; for that you should consider some sort of session mechanism)

the context.Value(key interface{}) interface{} interface function is how you retrieve values back out of the context.
