I am trying to output the Hyper HTTP Request Object as JSON. I am using Serde to Serialize the object to JSON.
Since I am not defining the HTTP Request Struct, I can't add the attribute #[derive(Serialize, Deserialize)] to it. any ideas on how to get around this?
my code:
use hyper::body::HttpBody as _;
use hyper::{Body, Client, Method, Request, Uri};
use hyper_tls::HttpsConnector;
#[cfg(feature = "std")]
use serde::{Deserialize, Deserializer, Serialize, Serializer};
use serde_json::{json, Result as re_, Value};
use tokio::io::{stdout, AsyncWriteExt as _};
#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error + Send + Sync>> {
let https = HttpsConnector::new();
// Client Object
let client = Client::builder().build::<_, hyper::Body>(https);
let uri: Uri = "https://api.api.com".parse()?;
let http_body = String::from(" body");
let content_length = http_body.chars().count();
//Build Request
let req = Request::builder()
.method(Method::POST)
.uri(uri)
.header("accept", "application/xml")
.header("content-type", "application/xml")
.header("Content-Length", content_length)
.body(Body::from(http_body))?;
// Serialize it to a JSON string.
let j = serde_json::to_string(&req)?;
// Print HTTP Request
println!("{}", j);
// Await the response...
let mut resp = client.request(req).await?;
println!("Response: {}", resp.status());
Ok(())
}
stack trace shows:
| let j = serde_json::to_string(&req)?;

If you want to derive
de/serializefor an external crate you can follow the oficial serde guide for doing so.Also, if you are trying to serialize it just to print it, maybe you could consider writing or using a default
DebugorDisplayimplementation over a wrapper. The defaultDebugone may do:
