Cannot do a get request in micropython on esp32

Question

I tried up to day to get requests working on micropython, tried installing libraries and everything. I use thonny IDE. what can i do?

Error:

Traceback (most recent call last):
  File "<stdin>", line 2, in <module>
  File "urequests.py", line 184, in post
  File "urequests.py", line 76, in request
OSError: -202

Code:

import urequests
response = urequests.get('http://pastebin.com/raw/4309d09')

Tried installing external libraries like 'micropython-urequests' etc

this won't fix it but you want to make sure you use https and not http if you are transferring sensitive data that you don't want a man in the middle to read. — easleyfixed

Debugging 101, make sure the content that you try to access is available. I try your URL, and got 404 page not found. So how can you get anything if it doesn't exist? — hcheung

My url is fake :), I think its obvious that i would know whether it works or not. — sev3333

you did not connect your board to wifi before requesting data from internet!

import network
import urequests

# Connect to network
wlan = network.WLAN(network.STA_IF)
wlan.active(True)
 
# Fill in your network name (SSID) and password here:
ssid = 'MyWIFI'
password = 'SuperSecretPassword'
wlan.connect(ssid, password)
while not wlan.isconnected():
    utime.sleep(1)  # sleep for a second
print("Network connected")

response = urequests.get('http://pastebin.com/raw/4309d09')
# do whatever is needed with your response
