Question

I’m struggling to translate this command (that I can successfully run)

curl -X POST https://www.googleapis.com/upload/drive/v2/files?uploadType=multipart \
-H "Authorization: Bearer ACCESS_TOKEN" \
-H "Content-Type: multipart/related" \
-F "metadata=@metadata.txt;type=application/json;charset=UTF-8" \
-F "file=@upload.jpg;type=image/jpeg"

to a python script using pycurl:

import pycurl
url = 'https://www.googleapis.com/upload/drive/v2/files?uploadType=multipart'

c = pycurl.Curl()
c.setopt(c.POST, 1)
c.setopt(c.USERAGENT, 'Curl')
c.setopt(c.VERBOSE, 1)
c.setopt(c.URL, url)
c.setopt(c.HTTPHEADER, [
    'Authorization: Bearer %s' % str(ACCESS_TOKEN),
    'Content-Type: multipart/related',
])

data = [
     ('metadata', (c.FORM_FILE, 'metadata.txt')),
     ('type', 'application/json'),
     ('charset', 'UTF-8'),
     ('file', (c.FORM_FILE, 'upload.jpg')),
     ('type', 'image/jpeg'),
]
c.setopt(c.HTTPPOST, data)
c.perform()
c.close()

but I always get this error when i run the script

Do you know the right translation?

I’ve removed the access token of the code examples for security reasons

Answer 1

just found the solution

data values must be this way:

data = [
    ('metadata', (
        c.FORM_FILE, 'metadata.txt', 
        c.FORM_CONTENTTYPE, 'application/json')),
    ('file', (
        c.FORM_FILE, 'upload.jpg', 
        c.FORM_CONTENTTYPE, 'image/jpeg'))
]
