ESP8266 Connecting to WIFI and Making HTTP Requests using MicroPython

There are two WiFi interfaces, one for the station (when the ESP8266 connects to a router) and one for the access point (for other devices to connect to the ESP8266).

Here is an example to connect ESP8266 to your wifi router.

>>> import network
>>> sta_if = network.WLAN(network.STA_IF)
>>> # check if station mode is activated or not.
>>> # activate the station mode.
>>> sta_if.connect('<your ESSID>', '<your password>') # connect to ssid using password.
>>> sta_if.isconnected() # check if you are connected to the ssid.
>>> sta_if.ifconfig() # check the ip address of the ESP8266 module.
('', '', '', '')

You can create a function and use it in the code instead of writing all of these lines again and again.

def do_connect():
    import network
    sta_if = network.WLAN(network.STA_IF)
    if not sta_if.isconnected():
        print('connecting to network...')
        sta_if.connect('<essid>', '<password>')
        while not sta_if.isconnected():
    print('network config:', sta_if.ifconfig())

Here is an example of http get request.

def http_get(url):
    _, _, host, path = url.split('/', 3) #get the domain name and rest of the url
    addr = socket.getaddrinfo(host, 80)[0][-1] #get address for the domain.
    s = socket.socket() # create a socket.
    s.connect(addr) # connect to the remote machine using that socket
    # make an http request.
    s.send(bytes('GET /%s HTTP/1.0\r\nHost: %s\r\n\r\n' % (path, host), 'utf8'))

    while True:
        data = s.recv(100)# read the response, 100 bytes at a time.
        if data:
            print(str(data, 'utf8'), end='')
    s.close()# close the socket.

All of the above codes are directly taken from the official documentation of Esp8266 and micropython. To get the complete details about the topics, please refer following links
