  • LaunchHTTPRequest()


    Lua   → VBScript


    This function calls (launches) a given URL (http request) and returns true if the request returns without error.

    Please see the Introduction chapter for some usage instructions.


    -- LaunchHTTPRequest
    -- Launches given URL.
    -- Parameter:
    --   sURL        complete url
    -- return value:
    --   boolean     true  - request returned with code 200
    --               false - request returned with code <> 200
    function LaunchHTTPRequest ( sURL )
        PBXScript.OutputTrace ("------> LaunchHTTPRequest ( sURL = '" .. sURL .. "' )")
        local bReturn = false
        local webreq = require "PBXWebRequest"
        if (webreq ~= nil) then
            local hsession, reponseCode
            hsession = webreq.new()
            local vBefore, vAfter, nDuration
            vBefore = os.time()
            responseCode = hsession:Execute()
            vAfter    = os.time()
            nDuration = os.difftime(vAfter, vBefore)
            PBXScript.OutputTrace("Web request returned after " .. math.floor(nDuration) .. " seconds the response code " .. responseCode)
            bReturn = (responseCode == 200)
        PBXScript.OutputTrace ("bReturn = " .. tostring(bReturn))
        PBXScript.OutputTrace ("<------ LaunchHTTPRequest")
        return bReturn


    This function makes use of the Server Script API class PBXWebRequest for the web request and the function PBXScript.OutputTrace() to write trace information into the SwyxServer trace file.


    This function was converted from VBScript into Lua from the initially posted version in this forum topic.
