Hello every one
Im trying to make a proxy using actix and while the core functionality works fine i struggle to get the raw data from a HttpRequest (the point being to print it into the user so that he can reproduce/modify the request.

Hi folks. I'm trying to set up my actix-web app with Docker. I've got the images and containers working, but can't find a way to connect to localhost. I've scoured all of the usual sites, published ports, tried host network, etc., but while the issue seems to be that while the requests are going in, actix isn't serving the response. Has anyone experienced anything like this? Repo is here: https://github.com/ToferC/health_rules_engine

from a quick glance: everything looks correct. that's certainly a weird bug

binding to 0.0.0.0 inside the container is the right thing to do
i notice you're mappinng 18080 to 8080 in the docker-compose, but that should be okay

what OS / environment are you running this in? is it just linux, or is it macos with docker desktop or windows with wsl

@ToferC

I’ve tried other port routings and same result. My default is 8088:8088. My base is using docker desktop for Mac and ive tested the same thing on Wsl2 / Ubuntu on my Windows machine.

When watching the traffic, i can see small (2k) traffic going in, but nothing comes back out and ive got a no response screen on browser and nada in console.

Should every endpoint function be async ? Or is it not useful?

I'm looking for an example for this use case: 1) website assets have been ready: index.html (1k), index.js(315k), wasm.js(9k), xxx.wasm(300k). 2) I want all assets can be provided as gzip. 3) I want all assets can be automatically gzipped during compiling time and it's part of the final binary file. 4) with this kind of setting, actix-web doesn't need to zip the assets during runtime but still can provide gzipped format to the client. Do we have this kind of example? Thanks.

Hi, I'm looking for a example to setup the X_FRAME_OPTIONS on my server

Could't find anything in the docs

anyone can give me some direction?

Do I need to create a custom middleware to inject the header in every response?

@nicolaujr

Just found the DefaultHeaders middleware, if anyone is interested

Hi! I was wondering if it is possible to extract the path name to be used for logging purposes. I have many of these created but wanted to keep track of what requests are hit the most. Is there a way to get this information? I am looking to get the string "/api/endpoint1" in the example below.

#[get("/api/endpoint1")] 
async fn api_request() -> Result<String> {
    Ok(String::from("Hello World"))
}

Hi. I am using v4 beta 10. It was working couple of days ago but now i get error like this;

#[post("/login")]
async fn post_login(user: Data<LoginUser>) -> Result<HttpResponse, Error> {
    Ok(HttpResponse::Ok().json(1))
}

.service(web::resource("/login").route(web::post().to(post_login)))

@CKalt

Anyone know how to capture type mismatch errors that result when using the Path information extractor so that I can produce a custom JSON format result instead of the default. For example I would like wrap the default error that gets emited like "Query deserialize error: invalid digit found in string" in a JSON object. But from the doc I'm not seeing how I might do this. I see a section on how to generate my own custom errors, but not how to capture and customize the default errors. Thank you for your help!!

Hey there, im attempting to update a small application of mine to use the RC. However im getting build errors.

Sorry have another question, just wondering if i can improve the code ergonomics a little. Prior to upgrading i'd have code like this:

let (game, rounds) = block(move || {
    let game = Game::find_by_id(&connection, game_id)?;
    let rounds = Round::belonging_to(&game).load::<Round>(&connection)?;
    Ok((game, rounds))
})
.await?;

Now with the changes to block(), it wraps the result for me. Since i want errors to return from the db operations there, i want to keep my own result. But this makes for a bit more code:

let data: Result<(Game, Vec<Round>), Error> = block(move || {
    let game = Game::find_by_id(&connection, game_id)?;
    let rounds = Round::belonging_to(&game).load::<Round>(&connection)?;
    Ok((game, rounds))
})
.await?;

let (game, rounds) = data?;

    HttpServer::new(move || {
        let auth = HttpAuthentication::bearer(bearer_auth_validator);
        App::new()
            .app_data(state.clone())
            .wrap(middleware::Logger::default())
            .wrap(auth)
            .service(put_job)
            .service(next)
    })

I got an application like this. I would like to put the auth only with the two services, and add another service without the bearer authentication. How would I go about that?

Fiddled a bit with it, looks like

    HttpServer::new(move || {
        let auth = HttpAuthentication::bearer(bearer_auth_validator);
        App::new()
            .app_data(state.clone())
            .wrap(middleware::Logger::default())
            .service(metrics)
            .service(web::scope("").wrap(auth).service(next).service(put_job))
    })

works

I have been using actix-web for a while and currently attempting to build an example where each actor/app has a local copy of some data and communicates/syncs it with a global manager through async channels. I wonder if there is a good way of providing each actor with local storage/data structures?

Is there a location documenting the expected number of release candidates before a major release? Just wondering when the 4.0.0 will come out of rc.

Hello everyone, not new to programming or web development, but brand new to rust and actix-web...just saying hey. I've been developing mostly in the java/typescript graphql/react/etc area for a little while now but looking into exploring what rust has to offer in terms of nextgen web development particularly with microservices

Morning, does anyone have an example of actix + protobuf service? Most of the time I've only seen protobuf with enums and struct but no service. I would assume it would create a service trait or something.

                            .wrap(Condition::new(
                                keycloak_auth.is_some(),
                                keycloak_auth.clone().unwrap(),
                            ))

This doesn't work because if it's None it will panic... What can I do here?

Wouldn't it be an idea to impl Transform for Option<T>?

@Samrose-Ahmed

Hi, does anyone know how to write a simple middleware that runs after the response is returned to client. I want to do some custom async task (e.g. emit metric) that doesn't impact response based on some state set during request processing.

https://docs.rs/actix-web/latest/src/actix_web/middleware/logger.rs.html#332
is the Drop impl for the response body stream wrapper

basically when this gets Drop'd you know the stream has either completed or errored

important bit is just res.map_body(...) (line 321) which you can use to wrap the stream in your own struct with other bits you'll need when the stream is done

I was wondering what the best way of encrypting proxied data through websockets would be.
I'm essentially making a proxy, but I don't want to be able to see the data.
I was thinking about implementing a TLS-like handshake, but then the server still gets both certificates and the encryption is breakable.

I'm going to be sending passwords and usernames through the network and the only server-side processing I'm going to be doing is mapping WSS streams to a random id.
