Descriptions

treq is an HTTP library inspired by requests but written on top of Twisted's Agents. Treq's request methods (`treq.get`, `treq.post`, etc.) and `treq.client.HTTPClient` constructor accept cookies as a dictionary. Such cookies are not bound to a single domain, and are therefore sent to *every* domain ("supercookies"). This can potentially cause sensitive information to leak upon an HTTP redirect to a different domain., e.g. should `https://example.com` redirect to `http://cloudstorageprovider.com` the latter will receive the cookie `session`. Treq 2021.1.0 and later bind cookies given to request methods (`treq.request`, `treq.get`, `HTTPClient.request`, `HTTPClient.get`, etc.) to the origin of the *url* parameter. Users are advised to upgrade. For users unable to upgrade Instead of passing a dictionary as the *cookies* argument, pass a `http.cookiejar.CookieJar` instance with properly domain- and scheme-scoped cookies in it.

treq es una librería HTTP inspirada en peticiones pero escrita sobre los Agentes de Twisted. Los métodos de petición de Treq ("treq.get", "treq.post", etc.) y el constructor "treq.client.HTTPClient" aceptan cookies como diccionario. Dichas cookies no están vinculadas a un único dominio, por lo que son enviadas a *every* los dominios ("supercookies"). Esto puede potencialmente causar que se filtre información confidencial en un redireccionamiento HTTP a un dominio diferente, por ejemplo, si "https://example.com" es redirigido a "http://cloudstorageprovider.com" este último recibirá la cookie "session". Treq versiones 2021.1.0 y posteriores vinculan las cookies dadas a los métodos de petición ("treq.request", "treq.get", "HTTPClient.request", "HTTPClient.get", etc.) al origen del parámetro *url*. Se recomienda a usuarios que actualicen. Para usuarios que no puedan actualizarse En lugar de pasar un diccionario como argumento *cookies*, pase una instancia de "http.cookiejar.CookieJar" con las cookies apropiadas para el dominio y el esquema
