Demonstrates how to specify the character encoding (charset) to be used for the body of an HTTP POST. Chilkat2-Python

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

http = chilkat2.Http()

req = chilkat2.HttpRequest()

# Load a JSON file containing strings with Polish chars.
json = chilkat2.JsonObject()
success = json.LoadFile("qa_data/json/has_polish_chars.json")
if (success == False):
    print(json.LastErrorText)
    sys.exit()

# 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.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.HttpVerb = "POST"
req.ContentType = "application/x-www-form-urlencoded"

resp = chilkat2.HttpResponse()
success = http.HttpReq("https://www.chilkatsoft.com/echoPost.cshtml",req,resp)

print(resp.BodyStr)

# 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.SendCharset = True
req.Charset = "windows-1250"
req.HttpVerb = "POST"
req.ContentType = "application/x-www-form-urlencoded"

if (success == False):
    print(http.LastErrorText)
    sys.exit()

print(http.LastHeader)
print(resp.BodyStr)

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