Using the WiFi connection, we can create a HTTP simple webserver on the module with the socket library.
```python
import usocket
import _thread
import time
from network import WLAN
import pycom
availablecolor = 0x001100
connectioncolor = 0x110000
# Thread for handling a client
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
else:
# Do something wth the received data...
print("Received: {}".format(str(r))) #uncomment this line to view the HTTP request
http = "HTTP/1.1 200 OK\r\nContent-Type: text/html\r\nConnection:close \r\n\r\n" #HTTP response
if "GET / " in str(r):
#this is a get response for the page
# Sends back some data
clientsocket.send(http + " You are connection "+ str(n) + "
Your browser will send multiple requests
hello!
change led color!")
elif "GET /hello "in str(r):
clientsocket.send(http + " Hello to you too!
go back ")
elif "GET /color" in str(r):
pycom.rgbled(0xFFFFFF)
clientsocket.send(http + " You are connection "+ str(n) + "
Your browser will send multiple requests
hello!
change led color!")
# Close the socket and terminate the thread
clientsocket.close()
pycom.rgbled(connectioncolor)
time.sleep_ms(500)
pycom.rgbled(availablecolor)
time.sleep(1)
wifi = WLAN()
wifi.init(mode=WLAN.AP, ssid="hello", auth=None, channel=1)
print("WiFi is up!")
time.sleep(1)
pycom.heartbeat(False)
pycom.rgbled(availablecolor)
# Set up server socket
serversocket = usocket.socket(usocket.AF_INET, usocket.SOCK_STREAM)
serversocket.setsockopt(usocket.SOL_SOCKET, usocket.SO_REUSEADDR, 1)
serversocket.bind(("192.168.4.1", 80))
# Accept maximum of 5 connections at the same time
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()
```
