Actix Form Data

A library for retrieving form data from Actix Web’s multipart streams. It can stream uploaded files onto the filesystem (its main purpose), but it can also parse associated form data.

Example

 use actix_form_data::{Error, Field, Form, FormData, Multipart, Value};
 use actix_web::{
     web::{post, resource},
     App, HttpRequest, HttpResponse, HttpServer,
 };
 use futures_util::stream::StreamExt;

 struct UploadedContent(Value<()>);

 impl FormData for UploadedContent {
     type Item = ();
     type Error = Error;

     fn form(_: &HttpRequest) -> Result<Form<Self::Item, Self::Error>, Self::Error> {
         Ok(Form::new()
             .field("Hey", Field::text())
             .field(
                 "Hi",
                 Field::map()
                     .field("One", Field::int())
                     .field("Two", Field::float())
                     .finalize(),
             )
             .field(
                 "files",
                 Field::array(Field::file(async move |_, _, mut stream| {
                     while let Some(res) = stream.next().await {
                         res?;
                     }
                     Ok(()) as Result<(), Error>
                 })),
             ))
     }

     fn extract(value: Value<Self::Item>) -> Result<Self, Self::Error>
     where
         Self: Sized,
     {
         Ok(UploadedContent(value))
     }
 }

 async fn upload(Multipart(UploadedContent(value)): Multipart<UploadedContent>) -> HttpResponse {
     println!("Uploaded Content: {:#?}", value);
     HttpResponse::Created().finish()
 }

 #[actix_rt::main]
 async fn main() -> Result<(), anyhow::Error> {
     HttpServer::new(move || App::new().service(resource("/upload").route(post().to(upload))))
         .bind("127.0.0.1:8080")?
         .run();
         // .await?;

     Ok(())
 }
