WEB Server

  • R

    @jczic I'm following your library, discovered some days ago.
    Many thanks for sharing! I will dig in a couple of days with it, at the moment I miss some more "elaborated" example (for novices as me).
    Will try to make a kind of wifimanager saving/retrieving values to flash in order to connect to a WiFi or keep settings.
    Again, many thanks for sharing this, great work!

    @pierrot10 Yes, the default IP for LoPy is 192.168.4.1.
    If you want, you can also use https://github.com/jczic/MicroDNSSrv to resolve names and connect to the good IP.

    @pierrot10
    if you start lopy in AP mode then it default ip is 192.168.*4*.1 not 0

    and what you got on UART? It start without an error?

    and please format your future post

    @jczic I am trying hard to make working MicroWebServer. In fact IsStarted return me always false. I really have no idea what I have to do.
    I tried different solution but without succes. WOuld it be possible to tell what wrong I did? Did I missed apackage?

    I supposed, I should connect the the WLAN 'lypo4_1' and open a browser with the 192.168.0.1?

    My structure is
    myProject/flash/www
    myProject/js
    myProject/main.py
    myProject/boot.py
    myProject/microWebSocket.py
    myProject/microWebSrv.py
    myProject/microWebTemplate.py

    Here is my code

    #import socket
    #import time
    #import binascii
    import pycom

    from network import WLAN
    #from pysense import Pysense
    from microWebSrv import MicroWebSrv

    #py = Pysense()
    print('\n\n** Init WLAN mode and WAP2')
    wlan = WLAN(mode=WLAN.AP,ssid="lypo4_1",auth=(WLAN.WPA2,'00000000')) # we call the constructor without params
    print('\n\n** Next...')

    Hi,

    If you are interested in a web server and a template language (.pyhtml) for pycom modules in micropython, you can try this release :
    https://github.com/jczic/MicroWebSrv

    (Be careful though, this takes memory.)

    also this can be somehow helpfull(it is normal python but..) if you need extend functionality
    https://hg.python.org/cpython/file/3.6/Lib/http/server.py

    I don't think that there's something builtin like Python's SimpleHTTPServer but the following topics might help you:

    https://github.com/RinusW/WiPy/tree/master/AiCWebserver

    OK. Your are right. I have to be more specific.
    In ESP8266 Arduino Core a httpserver class exists. It is very easy to setup a web server. I was wondering if exists something similar for pyCom.
