where to place the web request ?

Post by bellad » Thu Jan 16, 2020 2:15 pm

hello,
with my prog , i have placed my web request in the loop , but I need to update my page for running my loop , what awaits my prog and does not do its job

thank you for your answer

Code: Select all

Post by bellad » Thu Jan 16, 2020 2:46 pm

thank , can you be more specific
I forgot to say , i work with esp8266 ( esp12 ) ,not much sram !!

i think , if there is a connection request then he sends , else he pass
but how to ??

sorry , I am not strong enough to understand

the script is blocked by waiting for a connection

let's take a simpler example :
original :

Code: Select all

import network
import socket
  
def log(msg):
    print(msg)
  
  
def do_connect():
    sta_if = network.WLAN(network.STA_IF)
    if not sta_if.isconnected():
        log('connecting to network...')
        sta_if.active(True)
        sta_if.connect('<SSID>', '<PASSWORD>')
        while not sta_if.isconnected():
            pass
    log('network config:'+str( sta_if.ifconfig()))
  
def start_myserver():
    log('start server method')
    addr = socket.getaddrinfo('0.0.0.0', 80)[0][-1]
    s = socket.socket()
    s.bind(addr)
    s.listen(1)
    log('listening on'+str( addr))
    while True:
        cl, addr = s.accept()
        log('client connected from'+str(addr))
        cl.send(html)
        cl.close()
  
#main part
html = """<!DOCTYPE html>
<html>
    <head> <title>ESP8266</title> </head>
    <body>
        Bonjour
    </body>
</html>
"""
I would like to display the word 'good' in the loop away
as in my example, which doesn't work :

Code: Select all

import network
import socket
  
def log(msg):
    print(msg)
  
  
def do_connect():
    sta_if = network.WLAN(network.STA_IF)
    if not sta_if.isconnected():
        log('connecting to network...')
        sta_if.active(True)
        sta_if.connect('<SSID>', '<PASSWORD>')
        while not sta_if.isconnected():
            pass
    log('network config:'+str( sta_if.ifconfig()))
  
def start_myserver():
    log('start server method')
    addr = socket.getaddrinfo('0.0.0.0', 80)[0][-1]
    s = socket.socket()
    s.bind(addr)
    s.listen(1)
    log('listening on'+str( addr))
    while True:
        if s.accept() == True :
          cl, addr = s.accept()
          log('client connected from'+str(addr))
          cl.send(html)
          cl.close()
        else:
          print('good')
           
  
#main part
html = """<!DOCTYPE html>
<html>
    <head> <title>ESP8266</title> </head>
    <body>
        Bonjour
    </body>
</html>
"""
I try to make myself understood with my English translated by google !!

My minimal_webserver.py is also for ESP8266 ;)

Another example can you find here: viewtopic.php?f=16&t=7467
