How can I use the PrivateCookieJar in a FromRequest implementation?

[szattila98]

I want to access the private cookies in a FromRequest implementation but I have difficulties getting a PrivateCookieJar there to do so.

"I have difficulties" is not really a useful issue description. Can you please show a snippet of the code you have tried, and explain what behavior you observed (compilation error / runtime error / silent misbehavior)?

Thanks for the fast reply, I was a bit tired yesterday and felt that it was adequate, sorry about it. I solved it but I have a question, I will explain it as a reply to @davidpdrsn

You mean something like this https://docs.rs/axum/latest/axum/extract/index.html#accessing-other-extractors-in-fromrequest-implementations?

[szattila98]

Yeah something like that, I solved what I wanted, here it is.

It gets a cookie and creates an AuthenticatedUser so it prevents some boilerplate, especially when I extend the functionality.

But it did bring up a question which is, how does the PrivateCookieJar know what the key is? I have it generated or configured from .env elsewhere, but it knows and parses the private cookies with it.

[davidpdrsn]

It requires you to set the key via Extension like shown here https://docs.rs/axum-extra/latest/axum_extra/extract/cookie/struct.PrivateCookieJar.html#example and the struct is defined with the key type it uses:

pub struct PrivateCookieJar<K = Key> { ... }

I see, so it can access it internally, thank you very much.
