Lianja Requires Chilkat v11.0.0+

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
lcUrl = "https://www.example.com/someting?param1=123&param2=abc"
loResp = createobject("CkHttpResponse")
llSuccess = loHttp.HttpNoBody("GET",lcUrl,loResp)
if (llSuccess = .F.) then
    ? loHttp.LastErrorText
    release loHttp
    release loResp
    return
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 = .F.

//  Send a DELETE request to https://www.example.com/deleteSomething
lcUrl = "https://www.example.com/deleteSomething"
llSuccess = loHttp.HttpNoBody("DELETE",lcUrl,loResp)
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
lnStatusCode = loResp.StatusCode
