I want to write a webpage that fetches data from the Rust back-end. However, what I get from the back-end is some random HTML text. How can I transmit the data (e.g. some short plain text) from the back-end to the front-end?
Below is my front-end code:
import {useState} from 'react';
import './App.css';
import Container from 'react-bootstrap/Container';
import Row from 'react-bootstrap/Row';
import Button from 'react-bootstrap/Button';
function App() {
const [buttonText, setButtonText] = useState();
function handleClick() {
const req = new Request("127.0.0.1:3003", {method: 'GET'})
const headers = new Headers([["Content-Type", "plain/text"]])
fetch(req, headers).then(response =>
response.text()
).then(response =>
setButtonText(response)
).catch(err =>
alert(err)
)
}
return (
<div className="App">
<Container>
<Row>
<Button size="lg" onClick={handleClick}>fetch</Button>
<div>{buttonText}</div>
</Row>
</Container>
</div>
);
}
export default App;
Rust back-end code:
use std::net::SocketAddr;
use axum::{
routing::get,
Router,
};
#[tokio::main]
async fn main() {
// build our application with a single route
let app = Router::new().route("/", get(|| async { "Hello, world" }));
// run it with hyper on localhost:3001
axum::Server::bind(&SocketAddr::from(([127, 0, 0, 1], 3003)))
.serve(app.into_make_service())
.await
.unwrap();
}
What I assumed the text to be:
Hello, world!
What it actually is:
