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. B4X

Dim success As Boolean = 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.
Dim sbCompanyName As ChilkatStringBuilder
sbCompanyName.Initialize
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.
Dim sbUrl As ChilkatStringBuilder
sbUrl.Initialize
sbUrl.Append("https://chilkatsoft.com/example?company_name=")
sbUrl.Append(sbCompanyName.GetEncoded("url", "utf-8"))

Dim http As ChilkatHttp

'  Send the following HTTP GET request:

'  GET /example?company_name=Gr%C3%BCnh%C3%B6fer%20GmbH HTTP/1.1
