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

* For versions of Chilkat < 10.0.0, use CreateObject('Chilkat_9_5_0.Http')
loHttp = CreateObject('Chilkat.Http')

* Implements the following CURL command:

* curl -X POST \
* https://your-webapp-hostname:your-webapp-port/v1/media \
* -H 'Authorization: Bearer your-auth-token' \ 
* -H 'Content-Type: image/jpeg'
* --data-binary @your-file-path

* Use the following online tool to generate HTTP code from a CURL command
* Convert a cURL Command to HTTP Source Code

* For versions of Chilkat < 10.0.0, use CreateObject('Chilkat_9_5_0.BinData')
loBdRequestBody = CreateObject('Chilkat.BinData')
lnSuccess = loBdRequestBody.LoadFile("your-file-path")
IF (lnSuccess <> 1) THEN
    ? "Failed to load your-file-path"
    RELEASE loHttp
    RELEASE loBdRequestBody
    CANCEL
ENDIF

* Adds the "Authorization: Bearer your-auth-token" header.
loHttp.AuthToken = "your-auth-token"

loResp = loHttp.PBinaryBd("POST","https://your-webapp-hostname:your-webapp-port/v1/media",loBdRequestBody,"image/jpeg",0,0)
IF (loHttp.LastMethodSuccess = 0) THEN
    ? loHttp.LastErrorText
    RELEASE loHttp
    RELEASE loBdRequestBody
    CANCEL
ENDIF

* For versions of Chilkat < 10.0.0, use CreateObject('Chilkat_9_5_0.StringBuilder')
loSbResponseBody = CreateObject('Chilkat.StringBuilder')
loResp.GetBodySb(loSbResponseBody)
* For versions of Chilkat < 10.0.0, use CreateObject('Chilkat_9_5_0.JsonObject')

* Sample JSON response:
* (Sample code for parsing the JSON response is shown below)

* {
*   "messages": [
*     {
*       "id": "gBEGkYiEB1VXAglK1ZEqA1YKPrU"
*     }
*   ]
* }

* Sample code for parsing the JSON response...
