How to implement actix-web response to send file data stream, I want to send it to http response body by decompressing zip file
use zip;
use std::fs::File;
use std::io::prelude::*;
use encoding_rs::Encoder;
use std::str;
use actix_web::{web, App, HttpRequest, HttpServer, Responder, HttpResponse};
use urlencoding::{decode};
use std::sync::Mutex;
use futures::stream::{Stream};
struct MyData {
zip: zip::ZipArchive<File>,
}
#[actix_rt::main]
async fn main() -> std::io::Result<()> {
let paz_file = File::open("D:/test.zip").unwrap();
let mut paz = zip::ZipArchive::new(paz_file).unwrap();
let data = web::Data::new(Mutex::new(MyData { zip: paz }));
HttpServer::new(move || {
App::new()
.app_data(data.clone())
.route("/static/**", web::get().to(handle_res))
})
.bind("127.0.0.1:21607")?
.run()
.await?;
Ok(())
}
async fn handle_res(data: web::Data<Mutex<MyData>>, req: HttpRequest) -> impl Responder {
let mut data = data.lock().unwrap();
let paths = req.path().to_string();
let mut file_path = paths.replace("/static/", "");
file_path = decode(&file_path).unwrap();
{
let mut zip_file = data.zip.by_name(&file_path);
match zip_file {
Ok(mut f) => {
return HttpResponse::Ok()
//.header("content-type", "text/plain;charset=utf-8")
.streaming(f.bytes());
},
Err(e) => {
println!("{}", e.to_string());
return HttpResponse::NotFound().body("File Not Found");
}
}
}
}
Error:
the trait bound `std::io::Bytes<zip::read::ZipFile<'_>>: futures_core::stream::Stream` is not satisfied
.streaming(f.bytes());
| ^^^^^^^^^^ the trait `futures_core::stream::Stream` is not implemented for `std::io::Bytes<zip::read::ZipFile<'_>>`
