(JavaScript) URL Encoding Charset in POST Query Params
Demonstrates how to control the URL encoding charset in POST query params. Note: This example requires Chilkat v11.0.0 or greater.
var success = false;
// This example requires the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.
// We have the string "MÆRSK".
var nameWin1252Encoded = "M%E6RSK";
var sb = new CkStringBuilder();
success = sb.DecodeAndAppend(nameWin1252Encoded,"url","windows-1252");
var http = new CkHttp();
// We're setting the session log filename so we can see the exact request sent.
http.SessionLogFilename = "qa_output/sessionLog.txt";
// First demonstrate a simple application/x-www-form-urlencoded POST
var req = new CkHttpRequest();
// Set the Charset = "utf-8" to cause URL encoding to use utf-8.
req.Charset = "utf-8";
req.AddParam("name",sb.GetAsString());
req.HttpVerb = "POST";
req.ContentType = "application/x-www-form-urlencoded";
var resp = new CkHttpResponse();
success = http.HttpReq("https://www.chilkatsoft.com/something",req,resp);
if (success == false) {
console.log(http.LastErrorText);
return;
}
// This is the request that is sent:
// Notice that utf-8 is used in the query param (the letter 'Æ' is %C3%A6)
// POST /something HTTP/1.1
// Host: www.chilkatsoft.com
// Content-Type: application/x-www-form-urlencoded
// Content-Length: 15
//
// name=M%C3%A6RSK
// ---------------------------------------------------------------
// Switch to windows-1252
req.Charset = "windows-1252";
req.HttpVerb = "POST";
req.ContentType = "application/x-www-form-urlencoded";
success = http.HttpReq("https://www.chilkatsoft.com/something",req,resp);
if (success == false) {
console.log(http.LastErrorText);
return;
}
// This is the request that is sent:
// Notice that windows-1252 is used in the query param (the letter 'Æ' is %E6)
// POST /something HTTP/1.1
// Host: www.chilkatsoft.com
// Content-Type: application/x-www-form-urlencoded
// Content-Length: 12
//
// name=M%E6RSK
// ---------------------------------------------------------------
// Let's do the same with HttpSReq, switching back to utf-8
req.Path = "/something";
req.HttpVerb = "POST";
req.ContentType = "application/x-www-form-urlencoded";
req.Charset = "utf-8";
success = http.HttpSReq("www.chilkatsoft.com",443,true,req,resp);
if (success == false) {
console.log(http.LastErrorText);
return;
}
// This is the request that is sent:
// Notice that utf-8 is used in the query param (the letter 'Æ' is %C3%A6)
// POST /something HTTP/1.1
// Host: www.chilkatsoft.com
// Content-Type: application/x-www-form-urlencoded
// Content-Length: 15
//
// name=M%C3%A6RSK
// ---------------------------------------------------------------
// Let's do a POST with XML body where the query params are in the HTTP request start line,
// and the Content-Type is text/xml where the body of the request is XML.
req.Path = "/something";
req.HttpVerb = "POST";
req.ContentType = "text/xml";
success = req.LoadBodyFromString("<test>123</test>","utf-8");
req.Charset = "utf-8";
// Remember... our request object still contains the query param added in the above call to AddParam.
success = http.HttpSReq("www.chilkatsoft.com",443,true,req,resp);
if (success == false) {
console.log(http.LastErrorText);
return;
}
// This is the request that is sent:
// Notice that utf-8 is used in the query param (the letter 'Æ' is %C3%A6)
// POST /something?name=M%C3%A6RSK HTTP/1.1
// Host: www.chilkatsoft.com
// Content-Type: text/xml
// Content-Length: 16
//
// <test>123</test>
