(C#) URL Encoding Charset in POST Query ParamsDemonstrates how to control the URL encoding charset in POST query params.
// This example requires the Chilkat API to have been previously unlocked. // See Global Unlock Sample for sample code. // We have the string "MÆRSK". string nameWin1252Encoded = "M%E6RSK"; // Note: The DecodeAndAppend method is newly added in Chilkat v9.5.0.87 Chilkat.StringBuilder sb = new Chilkat.StringBuilder(); bool success = sb.DecodeAndAppend(nameWin1252Encoded,"url","windows-1252"); Chilkat.Http http = new Chilkat.Http(); // 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 Chilkat.HttpRequest req = new Chilkat.HttpRequest(); // Set the Charset = "utf-8" to cause URL encoding to use utf-8. req.Charset = "utf-8"; req.AddParam("name",sb.GetAsString()); Chilkat.HttpResponse resp = http.PostUrlEncoded("https://www.chilkatsoft.com/something",req); if (http.LastMethodSuccess == false) { Debug.WriteLine(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"; resp = http.PostUrlEncoded("https://www.chilkatsoft.com/something",req); if (http.LastMethodSuccess == false) { Debug.WriteLine(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 SynchronousRequest, switching back to utf-8 req.Path = "/something"; req.HttpVerb = "POST"; req.ContentType = "application/x-www-form-urlencoded"; req.Charset = "utf-8"; resp = http.SynchronousRequest("www.chilkatsoft.com",443,true,req); if (http.LastMethodSuccess == false) { Debug.WriteLine(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 PostXml 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. resp = http.SynchronousRequest("www.chilkatsoft.com",443,true,req); if (http.LastMethodSuccess == false) { Debug.WriteLine(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> |
