Migracja do wersji 1.x¶
Ta sekcja opisuje najważniejsze różnice pomiędzy 0.x a 1.x i ma na celu ułatwienie aktualizacji.
Zmiany w API¶
Response.json
jest teraz wywoływalne (callable), a nie właściwością (property) odpowiedzi.import requests r = requests.get('https://github.com/timeline.json') r.json() # *wywołanie* podnosi wyjątek jeśli dekodowanie JSON nie uda się
API dla
Session
zmieniło się. Obiekty sesji nie przyjmują już parametrów.Session
jest teraz pisane wielką literą, ale wciąż można używaćsession
dla kompatybilności wstecznej.s = requests.Session() # wcześniej sesja przyjmowała parametry s.auth = auth s.headers.update(headers) r = s.get('http://httpbin.org/headers')
Wszystkie request hooki zostały usunięte, za wyjątkiem
response
.Pomocnicy uwierzytelniania są teraz w oddzielnych modułach. Patrz requests-oauthlib i requests-kerberos.
Parametr dla żądań streamingowych został zmieniony z
