I was trying to utilize the HttpServer::stop function. I saved a reference to my earlier created "Server" in a global singleton state, which I picked up on receipt of a "terminate" command via my REST API. While issuing the command from my route handler I'm seeing a warning in the compiler (which is correct I guess): "unused implementer of
std::future::Future that must be used" - for this call: http_server.unwrap().stop(true);. The nice thing is: The stop works and it does not work if I put it all into an async fn and wait for it... So I disabled the linter warning and was fine.

Not sure if I should be concerned...
@robjtede Hi Rob, the number of actix samples is kind of overwhelming (https://github.com/actix/examples). I would need a minimalistic secure HTTP GET/POST/PUT/DELETE async sample. Is there some you could recommend out of the box?

Looks good. Thanks. Came across this sample https://docs.rs/actix-web/0.7.17/actix_web/client/index.html. It does not work the way it is shown. Just as info.

I'm using log4rs in conjunction with actix and I really have a hard time to prevent actix from logging. My "solution" right now is to set all known trace sources to "error", this helps at least to not get a completely messed log. But is is very cumbersome, since not all sources of trace are known beforehand, so I have to add more and more filters.
.logger(Logger::builder().build("actix_server::builder", LevelFilter::Error))
.logger(Logger::builder().build("actix_http::h1::decoder", LevelFilter::Error))Is there any known more generic solution to disable logging for actix entirely?

I don't have an issue posting 128kb slices, but actix does not receive anything if I go to a higher number like 256kb or 512kb.

Hi. Just started with Rust and am trying to work with actix and sqlx. Is this the proper way to share a db connection in the routes?
#[actix_web::main]
async fn main() -> Result<(), sqlx::Error> {
let db_url = env::var("DATABASE.URL").expect("DATABASE.URL is not set in .env file");
let mut listenfd = ListenFd::from_env();
// Create a connection pool
let db_pool = PgPoolOptions::new()
.max_connections(5)
.connect(&db_url)
.await?;
let mut server = HttpServer::new(move|| {
App::new()
.data(db_pool.clone()) // pass database pool to application so we can access it inside handlers
.service(hello)Also, am I supposed to clone the connection object here? Wouldn't I be just copying it? I thought it would be better to do just point to its existing value `.data(&db_pool), but the compiler says thats wrong.

from this example, request.match_info returns the path name and favico.ico, which triggers an error. what alternative do you suggest ?
async fn pages(request: HttpRequest) -> impl Responder {
let name = request.match_info().get("name").unwrap_or("World");
format!("Hello {}!", &name)
}
Hi, I am trying to use HttpAuthentication::bearer in a project that also uses actix-cors, if I use HttpAuthentication::bearer or actix-cors alone it works fine, but if I use both I get an error saying that cors has block the request due to No 'Access-Control-Allow-Origin' header is present on the requested resource. I've even tried with Cors::permissive(). I don't know if these two crates are not compatible or is a bug in actix-web-httpauth, I will appreciate some guidance, do I have to submit a bug? my main code is: ```#[actix_rt::main]
pub async fn init() -> std::io::Result<()> {
let port = env::var("PORT").unwrap_or_else(|_e| "8000".to_string());
let mut socket = "127.0.0.1".to_string();
socket.push(':');
socket = socket + &port;
pub async fn init() -> std::io::Result<()> {
let port = env::var("PORT").unwrap_or_else(|_e| "8000".to_string());
let mut socket = "127.0.0.1".to_string();
socket.push(':');
socket = socket + &port;
let db_state = db_mongodb::DB::init().await;
HttpServer::new(move || {
App::new()
.wrap(
//Cors::default()
Cors::permissive()
)
.wrap(IdentityService::new(
CookieIdentityPolicy::new(&PRIVATE_KEY)
.name("auth")
.http_only(false)
.path("/")
.secure(false),
))
.data(db_state.clone())
.service(
web::scope("/api")
.wrap(HttpAuthentication::bearer(auth::validator))
.configure(routes::init_secured)
)
.service(
web::scope("/public")
.configure(routes::init_public)
)
})
.bind(socket).unwrap()
.run()```
Hi, I'm using HttpAuthentication bearer as an authentication middleware layer, I have difficulties trying to figure out how I can add/modify information that is passed to the eventual route handlers. i.e. in the validator function that I defined and need to pass to the HttpAuthentication::bearer, I would like to be able to set a specific String that is accessible in the route that gets called eventually.
robjtede see the wrap attribute https://docs.rs/actix-web-codegen/0.4.0/actix_web_codegen/attr.get.html
jplatte multiple resources with the same path doesn't work, same as scope("") by the way (which kinda works, but not reliably, i.e. order matters and weird things like that)
jplatte Okay, thanks. Will create a new middleware that branches on the http method then if you can't recommend sth. better.
jplatte Although if this does indeed work with the macros, it may not be that hard to get this to work? Have never looked into actix-web's routing logic, so not sure.
jplatte * This is what I'm doing now:
pub async fn resource_mutation_admin_validator(
req: ServiceRequest,
) -> actix_web::Result<ServiceRequest> {
if req.method() == Method::GET {
Ok(req)
} else {
admin_validator(req).await
}
}used as .wrap(Preprocess(authz::resource_mutation_admin_validator)) with that Preprocess middleware I was talking about upstreaming a bit ago
hello every one is it possible to create multiple apps in same server in actix-web version 3 like
HttpServer::new(move || {
vec![
App::new()
.service(resource("/test/{id}").route(get().to(test))),
App::new()
.service(resource("/test1/{id}").route(get().to(test1)))]
})
.bind("0.0.0.0:8000")?
.run().await;

hey guys. I am new here. I am trying to use actix-web with cors. But I am getting an error like:
Compiling actix-cors v0.5.1

| ^^^^^^^^^^^^^^^^^ no `tiny_vec` in the rootand also when I am declaring actix_cors:Cors I have the message extern location for actix_cors does not exist. I am using actix-cors = "0.5.1" on Cargo.toml. What do you think about it?

Hello, I'm trying to use the
httpmock crate with actix to mock some requests I make with actix-web::Client but it doesn't seem to work, the mock server is up but the request never reaches it. Are there any known compatibility issues between theses crates? I'm wondering if httpmock using isahc as a http framework is causing any issue
println!("test1");
let client = Client::default();
println!("test2");
let request = client.get(MY_URI.as_str())
.timeout(Duration::from_secs(5))
.set_header("Authorization", token)
.send();
println!("test3");
let mut resp = match request.await {
Ok(val) => val,
Err(error) => {
log::warn!("{}", error);
return Err(ServiceError::MyError);
}
};
println!("test4");If
MY_URI is invalid like "google.com" an error is returned, but if its a mock server running locally with mockito or httpmock or a valid one ("http://www.google.com") it loops

Is there any way to conditionally start the actix system? Say, for example, I only want to start a server if the
--server flag is provided to my program, otherwise I don't want to start a server. From what I've seen it just starts automatically when the program starts which isn't what I want
proc macro is for easy async
Hello everyone, I'm having trouble with creating a route that accepts multipart form data in addition to url parameters. The header of my handler looks like this:
async fn post_files(mut payload: Multipart, web::Path((proj, name, version)): web::Path<(String, String, String)>) -> Result<HttpResponse, Error>payload.try_next() never returns Ok though. Does anyone have any idea how to debug this or see what I'm doing wrong? Thanks in advance!
