ESP32 has WIFI connectivity support, in this exercise we will test how to send http request.
Connect to WIFI
There is a file named with boot.py, it is executed on every boot, so we can put WIFI connection related code here
def do_connect(): import network wlan = network.WLAN(network.STA_IF) wlan.active(True) if not wlan.isconnected(): print('connecting to network...') wlan.connect('<wifi sid>', '<wifi password>') while not wlan.isconnected(): pass print('network config:', wlan.ifconfig()) do_connect()
Send http request
Once the WIFI is connected successfully, we can try to send request to RANDOM USER GENERATOR with code below, it will print a random user name every 5 seconds
- Install urequests - Download urequests.py, and save it the board with same file name.
- Code in main.py
import urequests import json import time while True: response = urequests.get('https://randomuser.me/api/') # res = json.loads(response.text) res = response.json() print("StatusCode: ",response.status_code) print(" userName: ",res['results']['login']['username']) time.sleep(5)
