(Ruby) REST Receive Response in Chunks

See more REST Examples

Demonstrates how to receive a REST HTTP response in chunks.

Note: This example requires Chilkat 10.1.0 or greater.

Chilkat Ruby Downloads

install from rubygems.org

gem install chilkat

or download... Ruby Library for Windows, MacOS, Linux, Alpine Linux

require 'chilkat'

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

rest = Chilkat::CkRest.new()

# Connect to the web server
bTls = true
port = 443
bAutoReconnect = true
success = rest.Connect("chilkatsoft.com",port,bTls,bAutoReconnect)
if (success == false)
    print rest.lastErrorText() + "\n";
    exit
end

# Send the request.
# This can be *any* kind of request: POST, GET, PUT, etc. using *any* of the Chilkat REST methods that send requests.
# For this example, we'll just GET a simple XML document that is about 274K in size.

success = rest.SendReqNoBody("GET","/hamlet.xml")
if (success == false)
    print rest.lastErrorText() + "\n";
    exit
end

# Get the response header.
statusCode = rest.ReadResponseHeader()
if (statusCode < 0)
    print rest.lastErrorText() + "\n";
    exit
end

print "response status code = " + statusCode.to_s() + "\n";

outputFile = "c:/temp/qa_output/hamlet.xml"

fac = Chilkat::CkFileAccess.new()
success = fac.OpenForWrite(outputFile)
if (statusCode < 0)
    print fac.lastErrorText() + "\n";
    exit
end

# Get the response in chunks.
# (Note: There are more efficient ways to simply download a file from a web server, such as by calling Chilkat's Http.Download method.
# The purpose of this method is to show how to receive a response chunk-by-chunk.)
bd = Chilkat::CkBinData.new()
status = 1
while status == 1
    # Read a minimum of 16000 bytes.
    # Note: Because of TLS message lengths, or the possibility of the response being either compressed (gzip/deflate) or in the HTTP chunked encoding,
    # the amount of data received in each call can be greater than the specified min size.
    # Chilkat will return from the call as soon as it has received an amount equal to or more than the specified size,
    # except for the very last chunk, which can be less that the min size or even 0 bytes.

    # The status will be one of three values:
    # -1 = error
    # 0 = received the last chunk of the response.
    # 1 = received a chunk, and more chunks are coming..

    # The received data is *appended* to the contents of the BinData object.
    status = rest.ReadRespChunkBd(16000,bd)
    if (status >= 0)
        print "Received chunk: " + bd.get_NumBytes().to_s() + " bytes" + "\n";
        fac.FileWriteBd(bd,0,0)
        bd.Clear()
    end

end

fac.FileClose()

print "Success." + "\n";
