Function goose_eggs::valid_header_value

pub fn valid_header_value<'a>(
    headers: &HeaderMap,
    header: (&'a str, &'a str)
) -> bool

Returns a bool indicating whether or not a header contains an expected value.

Returns true if the expected value was found, otherwise returns false.

Expects a &str tuple with a length of 2 where the first defines the header name and the second defines the header value, ie ("name", "value").

While you can invoke this function directly, it’s generally preferred to invoke validate_page or validate_and_load_static_assets which in turn invoke this function.

Example

use goose::prelude::*;
use goose_eggs::valid_header_value;

transaction!(validate_header_value).set_on_start();

async fn validate_header_value(user: &mut GooseUser) -> TransactionResult {
    let mut goose = user.get("/").await?;

    match goose.response {
        Ok(response) => {
            // Copy the headers so we have them for logging if there are errors.
            let headers = &response.headers().clone();
            if !valid_header_value(headers, ("server", "nginx")) {
                return user.set_failure(
                    &format!("{}: server header value not correct: {}", goose.request.raw.url, "nginx"),
                    &mut goose.request,
                    Some(headers),
                    None,
                );
            }
        }
        Err(e) => {
            return user.set_failure(
                &format!("{}: no response from server: {}", goose.request.raw.url, e),
                &mut goose.request,
                None,
                None,
            );
        }
    }

    Ok(())
