Procedure Test
    Handle hoReq
    Handle hoHttp
    String sJsonText
    Variant vResp
    Handle hoResp
    String sTemp1
    Boolean bTemp1

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

    Get Create (RefClass(cComChilkatHttpRequest)) To hoReq
    If (Not(IsComObjectCreated(hoReq))) Begin
        Send CreateComObject of hoReq
    End
    Get Create (RefClass(cComChilkatHttp)) To hoHttp
    If (Not(IsComObjectCreated(hoHttp))) Begin
        Send CreateComObject of hoHttp
    End

    // 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...
    Send ComSetRequestHeader To hoHttp "Authorization" "my-custom-computed-auth-value"

    // Another custom header for some hypothetical app:
    Send ComSetRequestHeader To hoHttp "X-Pass-Timestamp" "my-custom-computed-timestamp-value"

    // We don't need to set the Content-Type header, becaue it is automatically set by Chilkat
    // in the PostJson2 call below.

    // The following "Accept" header may be set, but it really isn't necessary:
    Send ComSetRequestHeader To hoHttp "Accept" "application/json"

    Move "{ some JSON text ... }" To sJsonText

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

    Get ComPostJson2 Of hoHttp "http://www.someserver.com/someJsonEndpoint" "application/json" sJsonText To vResp
    If (IsComObject(vResp)) Begin
        Get Create (RefClass(cComChilkatHttpResponse)) To hoResp
        Set pvComObject Of hoResp To vResp
    End
    Get ComLastMethodSuccess Of hoHttp To bTemp1
    If (bTemp1 <> True) Begin
        Get ComLastErrorText Of hoHttp To sTemp1
        Showln sTemp1
    End
    Else Begin
        // Display the JSON response.
        Get ComBodyStr Of hoResp To sTemp1
        Showln sTemp1
        Send Destroy of hoResp
