Send UTF-16 on TCP or TLS Socket

See more Socket/SSL/TLS Examples

Demonstrates how to send a string on a connected TCP or SSL/TLS socket such that it is the utf-16 byte representation that is sent. Ruby

require 'chilkat'

success = false

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

socket = Chilkat::CkSocket.new()

tls = false
maxWaitMs = 20000
domainOrIpAddr = "example.com"
port = 1234

# Connect to the whatever is expecting our connection...
success = socket.Connect(domainOrIpAddr,port,tls,maxWaitMs)
if (success != true)
    print socket.lastErrorText() + "\n";
    exit
end

# Let's say we have an XML file saved in the utf-16 byte representation,
# and we want to send it over the connection using the utf-16 byte representation...

# First the file into a Chilkat StringBuilder.
# Tell the LoadFile method that we are reading utf-16 bytes..
sbXml = Chilkat::CkStringBuilder.new()
success = sbXml.LoadFile("qa_data/xml/myUtf16.xml","utf-16")
if (success != true)
    print "Failed to load utf-16 XML file.." + "\n";
    exit
end

# Tell the socket object that we wish to send the utf-16 byte representation of the string.
socket.put_StringCharset("utf-16")

# Send the string as utf-16 bytes.
success = socket.SendSb(sbXml)
if (success != true)
    print socket.lastErrorText() + "\n";
    exit
end

# Let's say we wanted to instead send the string as utf-8 bytes.
# Just tell the socket object...
socket.put_StringCharset("utf-8")

# Send the string as utf-8 bytes.
success = socket.SendSb(sbXml)
if (success != true)
    print socket.lastErrorText() + "\n";
    exit
end

# If our XML file was utf-8, then just tell the StringBuilder that we're reading utf-8.
# Once the text is properly contained in the StringBuilder, we can send the contents in any other charset (windows-1252, utf-16, utf-8, etc.) 
# as long as it make sense (i.e. we obviously can't send Japanese text using a single-byte charset such as Windows-1252).
success = sbXml.LoadFile("qa_data/xml/myUtf8.xml","utf-8")
if (success != true)
    print "Failed to load utf-8 XML file.." + "\n";
    exit
end

# Send as utf-16
socket.put_StringCharset("utf-16")

# Send the string as utf-16 bytes.
success = socket.SendSb(sbXml)
if (success != true)
    print socket.lastErrorText() + "\n";
    exit
