Ich versuche, eine 0-Byte-Datei mit Anforderungen an owncloud hochzuladen. Ich würde gerne ein dateiähnliches Objekt dafür verwenden. Normalerweise würde ich es so machen:Das Hochladen einer 0-Byte-Datei in owncloud mit Python-Anfragen hängt
file_obj = io.BytesIO(b'')
response = requests.put('http://localhost/remote.php/webdav',
auth=('xxx', 'xxx'),
data=file_obj)
Aber es friert ein. Wenn ich den Prozess unterbrechen, sehe ich, wo es mit dem Stack-Trace hängt:
Traceback (most recent call last):

httplib_response = conn.getresponse(buffering=True)
TypeError: getresponse() got an unexpected keyword argument 'buffering'
During handling of the above exception, another exception occurred:

Wireshark sagt mir folgende Anfrage sendet Anträge, die in Ordnung zu sein scheint, aber wird nie eine Antwort:

Wenn ich eine leere Zeichenfolge senden, es funktioniert:
response = requests.put('http://localhost/remote.php/webdav/test.txt',
auth=('xxx', 'xxx'),
data='')

Dies funktioniert auch:
def chunker(file_obj):
buf = None
while buf != b'':
print('iter')
buf = file_obj.read(16*1024)
yield buf
file_obj = io.BytesIO(b'')
response = requests.put('http://localhost/remote.php/webdav/test.txt',
auth=('xxx', 'xxx'),
data=chunker(file_obj))
Irgendwelche Ideen, warum dies mit dateiähnliche Objekte nicht funktioniert? Ich verwende die neueste Version der Anfragen (2.9.1) und Python 3.5.
Scheint, dass "Anfragen" b0rken ist; Transfer-Encoding ist auf Chunked gesetzt, aber das ist kein richtiger Chunked-Body. –
