Get a webpage with ESP32

Post by AwesomeCronk » Fri Oct 11, 2019 1:33 am

I would like to connect an ESP32 to a server hosting the webpage ‘example.com’. I am using an Adafruit HUZZAH32 and Thonny IDE.
Thanks!

Hi,

Are you using CircuitPython or MicroPython.

The easiest way to do this is with urequests. On MicroPython for ESP32, this is included in the default firmware. It works a lot like the Python "requests" library.

Code: Select all

import urequests

r = requests.get("http://example.com/")
# Use one of these depending on what your response looks like:
print(r.content)
print(r.text)
print(r.json())
r.close()
On CircuitPython, take a look at https://circuitpython.readthedocs.io/pr ... t/api.html

Yes, use the instructions here http://docs.micropython.org/en/latest/e ... networking for connecting to the network first.
