actix_web 提供的标头无效

Question

I am getting this error running an actix-web based server

ERROR actix_http::h1::dispatcher] stream error: Request parse error: Invalid Header provided

The handler code is this:

#[derive(Serialize, Deserialize)]
pub struct Data {
   some_data: String
};
async fn handler_post(
  request: HttpRequest,
  data: web::Json<Data>
) -> impl Responder {
  HttpResponse::OK()
     .json(ApiResponse {
        status: "success"
     })
}

The headers being sent are accept, Content-Type and User-Agent. I don't know how to make it work. By the way, i'm using actix-web 4.

Answer 1

I tried the handler with actix version 4 and facing no issue

src/main.rs

use actix_web::{get, post, web, App, HttpResponse, HttpServer, Responder, HttpRequest};
use serde::{Serialize, Deserialize};

#[get("/")]
async fn hello() -> impl Responder {
    HttpResponse::Ok().body("Hello world!")
}

#[derive(Serialize, Deserialize)]
pub struct Data {
   some_data: String
}

#[derive(Serialize, Deserialize)]
pub struct ApiResponse<'a> {
   status: &'a str
}

#[post("/")]
async fn handler_post(
  request: HttpRequest,
  data: web::Json<Data>
) -> impl Responder {
  HttpResponse::Ok()
     .json(ApiResponse {
        status: "success"
     })
}

#[actix_web::main]
async fn main() -> std::io::Result<()> {
    HttpServer::new(|| {
        App::new()
            .service(hello)
            .service(handler_post)
    })
    .bind(("127.0.0.1", 8080))?
    .run()
    .await
}
