B4J Question [solved] questions around HttpJob and ServletRequest

[svanneste]

Hi,
I am currently learning B4X so that's not a critical question but I have some questions using data in ServletRequest when sent by a POST from HttpJob, please.

PostString
In fact making a POST, I am able to use the PostMultipart but absolutely not PostString because how do I get the string in the ServletRequest ?

ParameterMap
Should I be able to get a Map using ParameterMap when using PostMultipart or is it only used when a web form sends some data ? Or perhaps I miss a way to send parameters from HttpJob ?

Thanks for your replies.

My libraries versions are :
jOkHttpUtils2 2.93 // jServer 3.00

OK, I perhaps found a part of the reply :
ParameterMap is used with a GET request and Download2

but I still can't figure how to receive a string sent with PostString.

PostString and PostBytes let you set the POST payload to whichever value you like. If you want to send parameters using a standard format then use:

Sub Test
    Dim j As HttpJob
    j.Initialize("", Me)
    j.PostString("link...", "a=b&a=ccc&mmm=nnnn")
    j.GetRequest.SetContentType("application/x-www-form-urlencoded")
    Wait For (j) JobDone (j As HttpJob)
    If j.Success Then
        Log(j.GetString)
    End If
    j.Release
End Sub

Handler example:

Sub Handle(req As ServletRequest, resp As ServletResponse)
    Dim params As Map = req.ParameterMap
    For Each k As String In params.Keys
        Dim p() As String = params.Get(k)
        Dim l As List = p
        resp.Write($"${k}: ${l}
"$)
    Next
End Sub
