How to handle a none exist url

[Decodetalkers]

Like this . I have read the doc, but I still cannot handle it..

[fiag]

let mut res = surf::get(url).await?;
if res.status() != surf::StatusCode::Ok {
    println!("Failed to download url");
}

[Decodetalkers]

let mut res = surf::get(url).await?;
if res.status() != surf::StatusCode::Ok {
    println!("Failed to download url");
}

then how to return the surf::error, now my function return a surf::Result.

Thanks very much

Please read https://doc.rust-lang.org/book/ch09-02-recoverable-errors-with-result.html

let mut res = surf::get(url).await?;
if res.status() != surf::StatusCode::Ok {
    println!("Failed to download url");
}

Its my code

Then it panic at "await?", before handle the url

sss is not a valid url. Surf requires a string that can be parsed into a Url

This is what I need , I need to handle this error...,when people input a url or not url string, it will pop an error window

ahh. see the example at Request::new:

use surf::http::{Url, Method};

let url = Url::parse("https://httpbin.org/get")?;
let req = surf::Request::new(Method::Get, url);

let url = Url::parse("https://httpbin.org/get")?;
let req = surf::Request::new(Method::Get, url);

It works, thanks
