HTTP GET with Non-USASCII Query Params

See more HTTP Examples

This example illustrates how query parameters in a URL are typically encoded and transmitted. .NET Core C#

bool success = false;

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

// First, let's load the string "Grünhöfer GmbH" from a file.  (This is a fictitious company name.)
// The file uses the utf-8 charset encoding.
Chilkat.StringBuilder sbCompanyName = new Chilkat.StringBuilder();
success = sbCompanyName.LoadFile("qa_data/txt/companyName.txt","utf-8");
// Assuming success for this example...

// We'll send an HTTP GET request to https://chilkatsoft.com/example?company_name={company name}

// When sending an HTTP GET request with query parameters that contain accented characters 
// (e.g., umlauts: ä, ö, ü), they must be percent-encoded (URL encoded) to ensure proper transmission and 
// interpretation by the server.  This is based on their UTF-8 byte values.
Chilkat.StringBuilder sbUrl = new Chilkat.StringBuilder();
sbUrl.Append("https://chilkatsoft.com/example?company_name=");
sbUrl.Append(sbCompanyName.GetEncoded("url","utf-8"));

Chilkat.Http http = new Chilkat.Http();

// Send the following HTTP GET request:

// GET /example?company_name=Gr%C3%BCnh%C3%B6fer%20GmbH HTTP/1.1
// Host: chilkatsoft.com
// Accept: */*
// Accept-Encoding: gzip

Chilkat.StringBuilder sbResponse = new Chilkat.StringBuilder();
success = http.QuickGetSb(sbUrl.GetAsString(),sbResponse);
if (success == false) {
    Debug.WriteLine(http.LastErrorText);
    return;
}

Debug.WriteLine("response status code: " + Convert.ToString(http.LastStatus));
Debug.WriteLine(sbResponse.GetAsString());
