(CkPython) HTTP multipart/form-data UploadDemonstrates how to upload files to an HTTP server using a multipart/form-data POST.
import sys import chilkat # 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") if (success != True): print(req.lastErrorText()) sys.exit() 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.. # This sends the HTTP request (with 3 files being uploaded) to # http://www.mywebserver123abc.com/rcvFormDataUpload.aspx # resp is a CkHttpResponse resp = http.SynchronousRequest("www.mywebserver123abc.com",80,False,req) if (http.get_LastMethodSuccess() != True): print(http.lastErrorText()) else: print("HTTP response status: " + str(resp.get_StatusCode())) # See the online reference documentation for # other information that can be obtained from the response object. # To send using SSL/TLS, do this instead. # This sends to https://www.mywebserver123abc.com/rcvFormDataUpload.aspx # resp is a CkHttpResponse resp = http.SynchronousRequest("www.mywebserver123abc.com",443,True,req) if (http.get_LastMethodSuccess() != True): print(http.lastErrorText()) else: print("HTTP response status: " + str(resp.get_StatusCode())) # See the online reference documentation for # other information that can be obtained from the response object. |
