Trait RequestMutator 

pub trait RequestMutator:
    Send
    + Sync
    + 'static {
    // Required method
    fn mutate(&self, proxy_url: &str, req: Request) -> Request;
}

Mutates a cloned request just before it is dispatched through a specific proxy.

The scheduler calls mutate after try_clone() and before client.execute(), giving implementations a chance to inject per-proxy request headers such as cookies obtained from a prior WAF challenge solve.

Example

use scatter_proxy::RequestMutator;
use std::sync::Arc;

struct CookieMutator {
    proxy_manager: Arc<scatter_proxy::ProxyManager>,
}

impl RequestMutator for CookieMutator {
    fn mutate(&self, proxy_url: &str, mut req: reqwest::Request) -> reqwest::Request {
        if let Some(cookie_val) = self.proxy_manager.get_cookie(proxy_url) {
            let header_val = format!("acw_sc__v2={cookie_val}");
            if let Ok(v) = header_val.parse() {
                req.headers_mut().insert(reqwest::header::COOKIE, v);
            }
        }
        req
    }
}

Required Methods

fn mutate(&self, proxy_url: &str, req: Request) -> Request

Inject per-proxy modifications into req before it is sent.

proxy_url — the proxy node URL that will execute the request. req — an already try_clone()d request ready for execution.

Return the (possibly modified) request.
