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. Visual FoxPro

LOCAL lnSuccess
LOCAL loHttp
LOCAL lcUrl
LOCAL loResp
LOCAL lnStatusCode

lnSuccess = 0

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

loHttp = CreateObject('Chilkat.Http')

* 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
lcUrl = "https://www.example.com/someting?param1=123&param2=abc"
loResp = CreateObject('Chilkat.HttpResponse')
lnSuccess = loHttp.HttpNoBody("GET",lcUrl,loResp)
IF (lnSuccess = 0) THEN
    ? loHttp.LastErrorText
    RELEASE loHttp
    RELEASE loResp
    CANCEL
ENDIF

* 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 = 0

* Send a DELETE request to https://www.example.com/deleteSomething
lcUrl = "https://www.example.com/deleteSomething"
lnSuccess = loHttp.HttpNoBody("DELETE",lcUrl,loResp)
IF (lnSuccess = 0) THEN
    ? loHttp.LastErrorText
    RELEASE loHttp
    RELEASE loResp
    CANCEL
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
lnStatusCode = loResp.StatusCode
? "Response status: " + STR(lnStatusCode)

* Get the response body
? loResp.BodyStr
