HTTP POST JSON (application/json)

See more HTTP Examples

Demonstrates how to send a JSON POST using the application/json content-type. Visual FoxPro

LOCAL lnSuccess
LOCAL loReq
LOCAL loHttp
LOCAL lcJsonText
LOCAL loResp

lnSuccess = 0

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

loReq = CreateObject('Chilkat.HttpRequest')
loHttp = CreateObject('Chilkat.Http')

* If any custom headers need to be included with the POST, add them
* by calling SetRequestHeader

* Note: An application should never explicitly set the Content-Length header.
* The Content-Length is automatically computed and added by Chilkat.

* Here are some examples of custom headers.  

* Perhaps your particular app needs some sort of custom-computed Authorization header...
loHttp.SetRequestHeader("Authorization","my-custom-computed-auth-value")

* Another custom header for some hypothetical app:
loHttp.SetRequestHeader("X-Pass-Timestamp","my-custom-computed-timestamp-value")

* The following "Accept" header may be set, but it really isn't necessary:
loHttp.SetRequestHeader("Accept","application/json")

lcJsonText = "{ some JSON text ... }"

* To use SSL/TLS, simply use "https://" in the URL.

loResp = CreateObject('Chilkat.HttpResponse')
lnSuccess = loHttp.HttpStr("POST","http://www.someserver.com/someJsonEndpoint",lcJsonText,"utf-8","application/json",loResp)
IF (lnSuccess = 0) THEN
    ? loHttp.LastErrorText
    RELEASE loReq
    RELEASE loHttp
    RELEASE loResp
    CANCEL
ENDIF

* Display the JSON response.
