B4J Question how to use bearer authentication on my own jServer

[Alexander Stolte]

Hey, I'm writing an API for my app and while analyzing other APIs I've noticed that many are doing the authentication with oauth.

My question is how can i do a "bearer authentication" for my own jServer and is this free?

Greetings

My question is how can i do a "bearer authentication" for my own jServer

Sub Handle(req As ServletRequest, resp As ServletResponse)
    Dim bearer As String = req.GetHeader("Bearer") ' to check just a Bearer Header
    Dim authheadercomplete As String = req.GetHeader("Authorization") ' check authorizationheader
    ' and split authheadercomplete to have only the token afterwards...

Check your database now for any valid token and only go on in request if the token is valid.

and is this free?

i dont´see anything problematic in reading a header. Sure it is free

    Dim j As HttpJob
    j.Initialize("",Me)
    j.Download2("http://192.168.192.121:8888/sendmsg", _
    Array As String("title", "the Title", "body", "this is the textbody","topic","general"))
    Dim token As String = "This is a dummystr used as a Token"
    j.GetRequest.SetHeader("Authorization","Bearer "&token )

Inside the Server handler

    Dim bearerhdr As String = req.GetHeader("Authorization")
    If bearerhdr.Length > 7 Then
        Dim token As String = bearerhdr.SubString(7).Trim
        Log("Token from Auth-Header: "&token)
    End If

Result from serverlog

Token from Auth-Header: This is a dummystr used as a Token
