Send HTTP POST using non-UTF8 such as Windows-1250

See more HTTP Examples

Demonstrates how to specify the character encoding (charset) to be used for the body of an HTTP 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()

# Load a JSON file containing strings with Polish chars.
json = Chilkat::CkJsonObject.new()
success = json.LoadFile("qa_data/json/has_polish_chars.json")
if (success == false)
    print json.lastErrorText() + "\n";
    exit
end

# Add the request params expected by the server-side:
req.AddParam("tytul",json.stringOf("tytul"))
req.AddParam("tresc",json.stringOf("tresc"))

# Indicate we wish to explicitly send the charset attribute in the HTTP request header.
req.put_SendCharset(true)

# Send the POST
# You can send the POST to the URL below.  It will respond with the request body in quoted-printable format.
# Using quoted-printable, we can easily see the binary bytes for the accented chars.

req.put_HttpVerb("POST")
req.put_ContentType("application/x-www-form-urlencoded")

resp = Chilkat::CkHttpResponse.new()
success = http.HttpReq("https://www.chilkatsoft.com/echoPost.cshtml",req,resp)
if (success == false)
    print http.lastErrorText() + "\n";
    exit
end

print http.lastHeader() + "\n";
print resp.bodyStr() + "\n";

# Sample output:

# --------------------------------------------------
# POST /echoPost.cshtml HTTP/1.1
# Host: www.chilkatsoft.com
# Content-Type: application/x-www-form-urlencoded; charset=utf-8
# Content-Length: 79
# 
# <pre>tytul=3DPrzyk%C5%82ad&amp;tresc=3DPrzyk%C5%82ad
# %82oszenie</pre>
# --------------------------------------------------

# We can see by the %C5%82 that utf-8 was sent, because %C5%82 is the 2-byte representation of a particular Polish char.

# -----------------------
# However.. we can change the charset used for the HTTP request by specifying the request object's charset.

req.put_SendCharset(true)
req.put_Charset("windows-1250")
req.put_HttpVerb("POST")
req.put_ContentType("application/x-www-form-urlencoded")

success = http.HttpReq("https://www.chilkatsoft.com/echoPost.cshtml",req,resp)
if (success == false)
    print http.lastErrorText() + "\n";
    exit
end

print http.lastHeader() + "\n";
print resp.bodyStr() + "\n";

# Sample output...
# You can see how the bytes used for the Polish chars are now 1-byte per char (i.e. using Windows-1250) 

# --------------------------------------------------
# POST /echoPost.cshtml HTTP/1.1
# Host: www.chilkatsoft.com
