I'm trying to figure out how to write a MultiPart POST request to OneNote using Python. Here is what I've done so far:
url = ROOT_URL+"pages"
headers = {"Content-Type":"multipart/form-data; boundary=MyAppPartBoundary",
"Authorization" : "bearer " + access_token}
txt = """--MyAppPartBoundary
Content-Disposition:form-data; name="Presentation"
Content-type:text/html
<!DOCTYPE html>
<html>
<head>
<title>One Note Text</title>
</head>
<body>
<p>Hello OneNote World</p>
</body>
</html>
--MyAppPartBoundary--
"""
session = requests.Session()
request = requests.Request(method="POST", headers=headers,
url=url, data=txt)
prepped = request.prepare()
response = session.send(prepped)
However, whenever I go to run it, I get the error response "The multi-part payload was malformed." I've also tried it like this:
url = ROOT_URL+"pages"
headers = {"Content-Type":"multipart/form-data; boundary=MyAppPartBoundary",
"Authorization" : "bearer " + access_token}
txt = """<!DOCTYPE html>
<html>
<head>
<title>One Note Text</title>
</head>
<body>
<p>Hello OneNote World</p>
</body>
</html>"""
files = {'file1': ('Presentation', txt, 'text/html')}
session = requests.Session()
request = requests.Request(method="POST", headers=headers,
url=url, files=files)
prepped = request.prepare()
response = session.send(prepped)
Same thing. Even super basic:
headers = {"Content-Type":"multipart/form-data; boundary=MyAppPartBoundary",
"Authorization" : "bearer " + access_token}
files = {'file1': ('filename', 'data', 'text/plain')}
r = requests.post(url, headers=headers, files=files)
Gives that error. What am I doing wrong?
First hunch: Make sure line breaks in your request body are CRLF (not just LF). The RFC spec for multipart is very picky about that
