The on_request/on_response Vec lived on the ObscuraHttpClient shared by every page in the context, so a callback registered on one page fired for all pages (#408 cross-page bleed) and outlived its page. Callbacks now live in a per-page CallbackRegistry (Arc shared with the page's JS runtime state). Page-driven fetch paths (navigation, POST, scripts, stylesheets, robots.txt, module loads, JS fetch/XHR in both plain and stealth modes) pass the registry through; the HTTP client itself is callback-free. Adds callbacks_do_not_bleed_across_pages: page A's callback stays silent for page B's requests and stops firing after page A is dropped.
obscura
Embeddable Rust API for the Obscura
headless browser. Drive a real V8 + DOM browser (Browser, Page, Element,
CookieStore) directly from Rust, with no separate process or CDP round-trips.
Install
This crate is not published to crates.io, so depend on it via git. Building it
compiles Obscura from source, including its embedded V8 (deno_core), so the
first build is large and slow.
[dependencies]
obscura = { git = "https://github.com/h4ckf0r0day/obscura", features = ["api"] }
tokio = { version = "1", features = ["rt", "macros"] }
anyhow = "1"
Usage
use obscura::Browser;
use std::time::Duration;
#[tokio::main]
async fn main() -> anyhow::Result<()> {
let browser = Browser::builder()
.stealth(true)
.storage_dir("/tmp/cookies")
.build()?;
let mut page = browser.new_page().await?;
page.goto("https://example.com").await?;
let el = page.wait_for_selector("a", Duration::from_secs(5)).await?;
println!("{} -> {:?}", el.text(), el.attribute("href"));
Ok(())
