Struct CookieMiddleware 

pub struct CookieMiddleware {
    pub store: Arc<RwLock<CookieStore>>,
}

Middleware that keeps a shared cookie store across requests.

Fields

store: Arc<RwLock<CookieStore>>

Implementations

impl CookieMiddleware

pub fn new() -> Self

Creates a new CookieMiddleware with a shared CookieStore.

pub fn with_store(store: CookieStore) -> Self

Creates a new CookieMiddleware with a pre-populated CookieStore.

pub async fn from_json<P: AsRef<Path>>(path: P) -> Result<Self, SpiderError>

Load cookies from a JSON file, replacing all cookies in the store. The JSON format is the one used by the cookie_store crate.

pub async fn from_netscape_file<P: AsRef<Path>>( path: P, ) -> Result<Self, SpiderError>

Load cookies from a Netscape cookie file. This will add to, not replace, the existing cookies in the store.

pub async fn from_rfc6265<P: AsRef<Path>>(path: P) -> Result<Self, SpiderError>

Load cookies from a file where each line is a Set-Cookie header value. The Domain attribute must be explicitly set in each cookie line.

fn process_request<'life0, 'life1, 'async_trait>( &'life0 self, _client: &'life1 C, request: Request, ) -> Pin<Box<dyn Future<Output = Result<MiddlewareAction<Request>, SpiderError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

where Self: 'async_trait, 'life0: 'async_trait,

Intercepts a successful response after download.

fn handle_error<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, _request: &'life1 Request, error: &'life2 SpiderError, ) -> Pin<Box<dyn Future<Output = Result<MiddlewareAction<Request>, SpiderError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

Handles downloader errors for a request.
