Entwickler-Schnittstelle¶

Dieser Teil der Dokumentation deckt alle Schnittstellen von Requests ab. Für die Teile von Requests, die externe Bibliotheken benötigen, dokumentieren wir die wichtigsten hier an dieser Stelle und geben Links zur eigentlichen Dokumentation an.

Haupt-Schnittstelle¶

Die gesamte Funktionalität von Requests kann mit den folgenden sieben Methoden erreicht werden. Alle liefern eine Instanz der Klasse :class:`Response <Response>`_ zurück.

Untergeordnete Klassen¶

class requests.Request(method=None, url=None, headers=None, files=None, data={}, params={}, auth=None, cookies=None, hooks=None)¶

A user-created Request object.

Used to prepare a PreparedRequest, which is sent to the server.

Parameter:

method – HTTP method to use.
url – URL to send.
headers – dictionary of headers to send.
files – dictionary of {filename: fileobject} files to multipart upload.
data – the body to attach the request. If a dictionary is provided, form-encoding will take place.
params – dictionary of URL parameters to append to the URL.
auth – Auth handler or (user, pass) tuple.
cookies – dictionary or CookieJar of cookies to attach to this request.
hooks – dictionary of callback hooks, for internal usage.

Usage:

>>> import requests
>>> req = requests.Request('GET', 'http://httpbin.org/get')
>>> req.prepare()
<PreparedRequest [GET]>

deregister_hook(event, hook)¶: Deregister a previously registered hook. Returns True if the hook existed, False if not.

prepare()¶: Constructs a PreparedRequest for transmission and returns it.

register_hook(event, hook)¶: Properly register a hook.

class requests.Response¶

The Response object, which contains a server’s response to an HTTP request.

apparent_encoding¶: The apparent encoding, provided by the lovely Charade library (Thanks, Ian!).

content¶: Content of the response, in bytes.

cookies = None¶: A CookieJar of Cookies the server sent back.

elapsed = None¶: The amount of time elapsed between sending the request and the arrival of the response (as a timedelta)

iter_content(chunk_size=1, decode_unicode=False)¶: Iterates over the response data. When stream=True is set on the request, this avoids reading the content at once into memory for large responses. The chunk size is the number of bytes it should read into memory. This is not necessarily the length of each item returned as decoding can take place.

iter_lines(chunk_size=512, decode_unicode=None)¶: Iterates over the response data, one line at a time. When stream=True is set on the request, this avoids reading the content at once into memory for large responses.

Parameter:	request – The `PreparedRequest` to add headers to. kwargs – The keyword arguments from the call to send().

build_response(req, resp)¶

Builds a Response object from a urllib3 response. This should not be called from user code, and is only exposed for use when subclassing the HTTPAdapter

Parameter:	url – The URL to connect to. proxies – (optional) A Requests-style dictionary of proxies used on this request.

If the message is being sent through a proxy, the full URL has to be used. Otherwise, we should only use the path portion of the URL.

This shoudl not be called from user code, and is only exposed for use when subclassing the HTTPAdapter.

Parameter:	request – The `PreparedRequest` being sent. proxies – A dictionary of schemes to proxy URLs.

Migration auf 1.x¶

Dieser Abschnitt zeigt die Hauptunterschiede zwischen 0.x und 1.x auf und ist dazu gedacht, den Schmerz eines Upgrades möglichst gering zu halten.

Änderungen der API¶

Response.json ist jetzt ein callable und nicht länger eine Eigenschaft einer Serverantwort.

import requests
r = requests.get('https://github.com/timeline.json')
r.json()   # Dieser *Aufruf* wirft eine Exception, sollte die JSON-Dekodierung fehlschlagen

Die Session API hat sich geändert. Session-Objekte erhalten keine Parameter mehr. Session wird jetzt mit großem Anfangsbuchstaben geschrieben, aber das Objekt kann aus Kompatibilitätsgründen weiterhin klein geschrieben als session instantiiert werden.
```
s = requests.Session()    # früher konnten Parameter übergeben werden
s.auth = auth
s.headers.update(headers)
r = s.get('http://httpbin.org/headers')
```
Alle Hooks für Anfragen wurden entfernt, mit Ausnahme von ‘response’.
Die Hilfsroutinen für die Authentifizierung wurden in separate Module ausgegliedert. Sehen Sie sich dazu requests-oauthlib and requests-kerberos an.

Der Parameter für Streaming-Anfragen wurde von prefetch in stream geändert und die Logik invertiert. Zusätzlich muss stream jetzt angegeben werden, um die Rohdaten der Serverantwort zu lesen.
```
# in 0.x, wurde das gleiche Ergebnis mit der Angaben von prefetch=False erreicht
r = requests.get('https://github.com/timeline.json', stream=True)
r.raw.read(10)
```
Der config Parameter für Anfragen wurde entfernt. Einige der davon betroffenen Optionen werden jetzt in einer Session konfiguriert, wie z.B. keep-alive und die meximale Anzahl von Redirects. Die Option für ausführliche Informationen (verbosity) sollte über die Konfiguration des Loggings gesetzt werden.
```
# Ausfürhliche Informationen sollten jetzt über das Logging konfiguriert werden
my_config = {'verbose': sys.stderr}
requests.get('http://httpbin.org/headers', config=my_config)  # schlecht!
```

Lizensierung¶

Ein Hauptunterschied, der nichts mit der API zu tun hat, ist eine Änderung der Lizensierung von der ISC Lizenz zur Apache 2.0 Lizenz. Die Apache 2.0 Lizenz stellt sicher, dass Beiträge zu Requests ebenfalls von der Apache 2.0 Lizenz abgedeckt sind.
