Webserver - Access point



  • Hi All,
    Where can I find a good functional example of a web server that acts as an access point?
    If possible I would like to store the web pages in the file system.
    It should be easy to add routes.
    It will be awesome if provision is made for dynamic data
    Any guidance will be appreciated.



  • @nftylitak Thnx for the feedback. I did see this. I think it is approx 150K in size, a bit big but comes with a lot of functionality.
    Not sure how to get started with it. THNX!!



  • @Gijs Thnx for the feedback. I will definitely look into it. It looks simple enough to do an interface for setting network credentials etc. Much appreciated.



  • We have been using MicroWebSrv2 that allows you to serve any files needed. Also supports a custom file type: pyhtml that you can embed python code, it will be first processed by the web engine, then produce the actual html file finally it will serve it.



  • Hi,
    I made this example a while ago. Some adapting is required but I believe you should be able to make it work!
    Best,

    def client_thread(clientsocket,n):
        # Receive maxium of 12 bytes from the client
        r = clientsocket.recv(4096)
    
        # If recv() returns with 0 the other end closed the connection
        if len(r) == 0:
            clientsocket.close()
            return

    serversocket.listen(5)
    
    # Unique data to send back
    c = 1
    while True:
        # Accept the connection of the clients
        (clientsocket, address) = serversocket.accept()
        # Start a new thread to handle the client
        _thread.start_new_thread(client_thread, (clientsocket, c))
        c = c+1
    serversocket.close()
