(CkPython) HTTPS Upload with Client SSL Certificate

This example shows how to use a client-side certificate with HTTPS to upload one or more files to a web server.

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

http = chilkat.CkHttp()

req = chilkat.CkHttpRequest()
req.put_HttpVerb("POST")
req.put_ContentType("multipart/form-data")
req.put_Path("rcvFormDataUpload.aspx")

# Send an "Expect: 100-continue" header in the request.
# This causes the HTTP server to end a 100-continue response
# immediately after receiving the HTTP header.  The client
# (Chilkat) will receive this intermediate response, and if
# it's not an error response, it knows that the HTTP server will
# accept the data that is forthcoming.
# The alternative is to get an error response after trying to upload
# the entire contents of the files.
req.AddHeader("Expect","100-continue")

# Call AddFileForUpload2 for each file to be uploaded in the HTTP multipart/form-data POST
# To allow Chilkat to determine the content-type automatically based on file-extension,
# call AddFileForUpload instead.

# The 1st arg is the filename passed in the HTTP request.
# The 2nd arg is the path in the local filesytem.
# The file is not loaded into memory.  It is streamed directly from the file
# when the HTTP POST is sent.
success = req.AddFileForUpload2("starfish.jpg","c:/qa_data/starfish.jpg","image/jpg")

success = req.AddFileForUpload("something.pdf","c:/qa_data/something.pdf")
if (success != True):
    print(req.lastErrorText())
    sys.exit()

# Its also possible to add a file from a string:
success = req.AddStringForUpload("test.xml","test.xml","<abc>This is the test.xml content</abc>","utf-8")
# We'll assume success since no files are involved..

cert = chilkat.CkCert()
success = cert.LoadPfxFile("c:/qa_data/pfx/test.pfx","pfx_password")
if (success != True):
    print(cert.lastErrorText())
    sys.exit()

# Set the certificate to be used for mutual TLS authentication
# (i.e. sets the client-side certificate for two-way TLS authentication)
success = http.SetSslClientCert(cert)
if (success != True):
    print(http.lastErrorText())
    sys.exit()

# This sends the HTTP request (with 3 files being uploaded) to
# https://www.example.com/rcvFormDataUpload.aspx

# resp is a CkHttpResponse
resp = http.SynchronousRequest("www.example.com",443,True,req)

    # other information that can be obtained from the response object.
