GET request with urequests on ESP8266 results in OSError: -2 #153

Closed stlehmann closed 7 years ago

stlehmann commented 7 years ago

I am trying to send a simple GET request to a host. Everything is fine but after the second or third request I will get an OSError: -2. The code I use is simple:

from urequests import get

>>> get('http://mrl33h.de/')
<Response object at 3fff2250>
>>> get('http://mrl33h.de/') 
<Response object at 3fff2840>
>>> get('http://mrl33h.de/')
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "urequests.py", line 101, in get
  File "urequests.py", line 51, in request
OSError: -2

I can not really put my finger on what's wrong here. I'm using MicroPython v1.8.7-7-gb5a1a20a3 from 09.01.2017.

I think you have to close the Socket. Get returns a response object, call close() with it.

Ah I see. This solves the issue. Thank you for that. It is a bit confusing though because I wouldn' t expect to need to close my response object. How about using a context manager instead?
