How to convert a http::Request to a reqwest::Request?

Hello!
How to convert a http::Request to reqwest::Request?

I am trying use the method try_from:

but not working correct.

Code:

 //...
 // Vec<u8> to String
 let text = String::from_utf8(buf).unwrap();
 println!("HTTP text: {}", text);

 use http::Request;
 let request = Request::new(text);

 use reqwest::Request;
 match reqwest::Request::try_from(request)
 {
     Ok(req) => { println!("HTTP req: {:?}", req); },
     Err(e) => { println!("HTTP e: {:?}", e); }
 };

Output:

http::Request::new takes request body, not the full request with headers. Not sure if it's possible to build it this way - quick search through docs didn't reveal anything.

Thanks for your reply.

I need convert a Vec<u8> to reqwest::Request.
but I can't use the reqwest to parse a http query.

4

A Vec of what?

5

@Cerberuser Vec<u8>

6

I mean, what does this Vec contain, semantically? If it's the raw bytes of HTML request (the buf in the original code), then why do you need reqwest at all?

7

Yes. It's raw bytes of http request.
I am writing a simple proxy server/http packet inspector. I need a request to validate and debug.

I just trying to parse an http request using the hyper library.
And I have a similar problem : hyper::Error(User(AbsoluteUriRequired))
Is the query corrupted, incorrect?

Web browser: Mozilla Firefox

Looks like so IMO:

GET http://wp.pl/ HTTP/1.1
Host: wp.pl

this should rather be

GET / HTTP/1.1
Host: wp.pl

(the path part should start from /).

Also, as @Cerber-Ursi suggests, neither the http library nor the reqwest library don't provide API for HTTP parsing, which is what you want. The http::Request::new method was certainly not what you wanted (interesting where the error came from then..., as it suggests some parsing was done. Perhaps http::Request has some defaults for headers, which are invalid in eyes of reqwest::Request?)

Anyway, perhaps httparse is what you want? Seems to be the parsing crate used by hyper (and transitively, by reqwest).

httparse is working well. But I need send the request to server (forward).

I need a solution that make:

  1. Parses a http request.
  2. Sends the http request to the next http server (target).
10

Use httparse to get all components of request.

Use reqwest::Reqwest methods to build the request from components, provided by the first step.
