HTTP Methods - GET and DELETE

Demonstrate a method for sending HTTP requests that don't have a request body, such as for GET or DELETE requests. Lianja

llSuccess = .F.

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

loHttp = createobject("CkHttp")

// Specifiy a session log file so we can see the exact request/response
loHttp.SessionLogFilename = "c:/aaworkarea/sessionLog.txt"

// Perhaps add a custom header or two..
loHttp.SetRequestHeader("x-exz-date","20201012T235046Z")
loHttp.SetRequestHeader("x-exz-id","1234")

// Send a GET request to https://www.example.com/someting?param1=123&param2=abc

    release loHttp
    release loResp

// The GET request that is sent looks like this.
// The Accept and Accept-Encoding headers are automatically added by default.

// 	GET /someting?param1=123&param2=abc HTTP/1.1
// 	Host: www.example.com
// 	Accept: */*
// 	Accept-Encoding: gzip
// 	x-exz-date: 20201012T235046Z
// 	x-exz-id: 1234

// Get the response status
lnStatusCode = loResp.StatusCode
? "Response status: " + str(lnStatusCode)

// Get the response body
? loResp.BodyStr

// -------------------------------------------------------------
// Let's say we want to send a DELETE request, and we only want to accept an application/json response,
// and we don't want gzipped responses...

// First remove the previously specified custom headers.
loHttp.ClearHeaders()

// Indicate we only accept application/json non-gzipped responses.
loHttp.Accept = "application/json"
loHttp.AllowGzip = .F.

// Send a DELETE request to https://www.example.com/deleteSomething
lcUrl = "https://www.example.com/deleteSomething"

if (llSuccess = .F.) then
    ? loHttp.LastErrorText
    release loHttp
    release loResp
    return
endif

// The DELETE request that is sent looks like this.
// The empty Accept-Encoding header value means we only want non-compressed responses.

// 	DELETE /deleteSomething HTTP/1.1
// 	Host: www.example.com
// 	Accept: application/json
// 	Accept-Encoding: 

// Get the response status
