HTTP GET with Non-USASCII Query Params

This example illustrates how query parameters in a URL are typically encoded and transmitted. Visual FoxPro

LOCAL lnSuccess
LOCAL loSbCompanyName
LOCAL loSbUrl

lnSuccess = 0

* 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.
loSbCompanyName = CreateObject('Chilkat.StringBuilder')
lnSuccess = loSbCompanyName.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.
loSbUrl = CreateObject('Chilkat.StringBuilder')
loSbUrl.Append("https://chilkatsoft.com/example?company_name=")
loSbUrl.Append(loSbCompanyName.GetEncoded("url","utf-8"))

loHttp = CreateObject('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
