Errors with esp32

[sornen]

Micropython v1.20.0 and the latest Microdot produces a number of errors on a esp32 devkit:

With this code

from microdot import Microdot, Response

app = Microdot()
Response.default_content_type = 'text/html'

@app.route('/')
def index():
    return 'Hello, world!'

app.run(debug=True)

the error is

Starting sync server on 0.0.0.0:5000...
<Request object at 3ffe84f0>
Traceback (most recent call last):
  File "microdot.py", line 1212, in dispatch_request
TypeError: function takes 0 positional arguments but 1 were given
GET / 500

Also having a problem with microdot_asyncio

With this code

import uasyncio as asyncio
from microdot_asyncio import Microdot

app = Microdot()

@app.route('/')
async def index():
    return 'Hello, world!'

async def main():
    await app.start_server(debug=True)

asyncio.run(main())

the error is

Starting async server on 0.0.0.0:5000...
Traceback (most recent call last):
  File "microdot_asyncio.py", line 370, in dispatch_request
  File "microdot_asyncio.py", line 441, in _invoke_handler

Your request handlers are incorrect. You need to accept the request object as an argument. Maybe you are too used to Flask. ;-)

Ah ok just found this out now and it is working. I was following the documentation in the supplied modules which does not show a request object.

Updated working code for future reference.

from microdot_asyncio import Microdot

app = Microdot()

@app.route('/')
async def index(request):
    return 'Hello, world!'
app.run(debug=True)

Awesome project.

@sornen do you mean that my documentation is missing the request argument? Where exactly?

[sornen]

for both microdot.py and microdot_asyncio.py the document strings for def run() show examples which are missing the request object. The documentation for microdot is fine in this regard, but I looked at the modules first and forgot there was excellent documentation that showed the correct call. My bad.

[miguelgrinberg]

Thanks, I have fixed those examples now!
