HTTP multipart/form-data Upload

See more HTTP Examples

Demonstrates how to upload files to an HTTP server using a multipart/form-data POST. Ruby

require 'chilkat'

success = false

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

http = Chilkat::CkHttp.new()

req = Chilkat::CkHttpRequest.new()
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 == false)
    print req.lastErrorText() + "\n";
    exit
end

success = req.AddFileForUpload("something.pdf","c:/qa_data/something.pdf")
if (success == false)
    print req.lastErrorText() + "\n";
    exit
end

# 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 = Chilkat::CkHttpResponse.new()
success = http.HttpSReq("www.mywebserver123abc.com",80,false,req,resp)
if (success == false)
    print http.lastErrorText() + "\n";
    exit
end

print "HTTP response status: " + resp.get_StatusCode().to_s() + "\n";
# 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
success = http.HttpSReq("www.mywebserver123abc.com",443,true,req,resp)
if (success == false)
    print http.lastErrorText() + "\n";
    exit
end

print "HTTP response status: " + resp.get_StatusCode().to_s() + "\n";
# See the online reference documentation for 
# other information that can be obtained from the response object.
