How to retrieve a readable session in middleware? #22

You might want to look at how axum-login does this: you'll want to pull the SessionHandle off the request and then can acquire either a readable or writable guard. |

Thanks, this is what I ended up with: pub async fn flash<S: Send + 'static>(
mut req: Request<S>,
next: Next<S>,
) -> Result<impl IntoResponse> {
let Extension(session_handle): Extension<SessionHandle> = req.extract_parts().await?;
let session = session_handle.read().await;
let payload = session.get::<bool>("signed_in").unwrap_or(false);
req.extensions_mut().insert(payload);
Ok(next.run(req).await)

That's a good question: I don't know the answer. It might require looking at the implementation more closely (I don't recall if the docs mention this). |

Okay, I ran into another problem. This is what my router looks like: let hidden = Router::new()

.layer(TraceLayer::new_for_http())
.with_state(app)Whenever I visit |

Yeah I managed to get that far. Now I figured out that my |

Sorry for the late reply. Skimmed through #13 before I realized I didn't drop my reader after spawning a writer in a function call where the reader was still in scope. |
The example on docs.rs cites the following code:
This is what I have:
However, I want to embed state in the
Requestso that the next handler knows whether the user is logged in or not. I'm using Askama for templating in case this is relevant.The text was updated successfully, but these errors were encountered:
