#  This requires the Chilkat API to have been previously unlocked.
#  See Global Unlock Sample for sample code.

http = chilkat.CkHttp()

#  If SharePoint Windows classic authentication is used, then set the
#  Login, Password, LoginDomain, and NtlmAuth properties.
http.put_Login("SHAREPOINT_USERNAME")
http.put_Password("SHAREPOINT_PASSWORD")
http.put_LoginDomain("SHAREPOINT_NTLM_DOMAIN")
http.put_NtlmAuth(True)

#  The more common case is to use SharePoint Online authentication (via the SPOIDCRL cookie).
#  If so, do not set Login, Password, LoginDomain, and NtlmAuth, and instead
#  establish the cookie as shown at SharePoint Online Authentication

#  Indicate that we want a JSON reply
http.put_Accept("application/json;odata=verbose")

#  Update /Documents/ChilkatTest/sample.docx with new content...
req = chilkat.CkHttpRequest()
req.put_HttpVerb("POST")
req.put_Path("/_api/web/GetFileByServerRelativeUrl('/Documents/ChilkatTest/sample.docx')/$value")
#  Give the location of the file to be uploaded.
#  Note: The file is not loaded into memory at this point.  It is never fully loaded
#  into memory.  Instead, the file data is streamed directly from the file when
#  when the upload occurs.
req.StreamBodyFromFile("qa_data/msword/sample.docx")

#  We need to add a form digest value in the X-RequestDigest header field.
#  See this example for details on
#  how to get (and cache) a form digest value
req.AddHeader("X-RequestDigest","SHAREPOINT_FORM_DIGEST")

#  Also need to add this header..
req.AddHeader("X-HTTP-Method","PUT")

#  Upload..
bUseTls = True
# resp is a CkHttpResponse
resp = http.SynchronousRequest("SHAREPOINT_HTTPS_DOMAIN",443,bUseTls,req)
if (http.get_LastMethodSuccess() != True):
    print(http.lastErrorText())
    sys.exit()

#  A successful update will return a 204 status code with an empty body.
#  A non-successful update will return a JSON response body..
