aiohttp_debugtoolbar provides a debug toolbar for your aiohttp web application. Library is port of pyramid_debugtoolbar and still in early development stages. Basic functionality has been ported:
- basic panels
- intercept redirects
- intercept and pretty print exception
- interactive python console
- show source code
HeaderDebugPanel, PerformanceDebugPanel, TracebackPanel, SettingsDebugPanel, MiddlewaresDebugPanel, VersionDebugPanel, RoutesDebugPanel, RequestVarsDebugPanel, LoggingPanel
Are you coder looking for a project to contribute to python/asyncio libraries? This is the project for you!
$ pip install aiohttp_debugtoolbarIn order to plug in aiohttp_debugtoolbar you have to attach middleware to your aiohttp.web.Application, and call aiohttp_debugtoolbar.setup
import aiohttp_debugtoolbar
app = web.Application(loop=loop,
middlewares=[aiohttp_debugtoolbar.middleware])
aiohttp_debugtoolbar.setup(app)import asyncio
import jinja2
import aiohttp_debugtoolbar
import aiohttp_jinja2
from aiohttp import web
@aiohttp_jinja2.template('index.html')
def basic_handler(request):
return {'title': 'example aiohttp_debugtoolbar!',
'text': 'Hello aiohttp_debugtoolbar!',
'app': request.app}
@asyncio.coroutine
def exception_handler(request):
raise NotImplementedError
@asyncio.coroutine
def init(loop):
# add aiohttp_debugtoolbar middleware to you application
app = web.Application(loop=loop,
middlewares=[aiohttp_debugtoolbar.middleware])
# install aiohttp_debugtoolbar
aiohttp_debugtoolbar.setup(app)
template = """
<html>
<head>
<title>{{ title }}</title>
</head>
<body>
<h1>{{ text }}</h1>
<p>
<a href="{{ app.router['exc_example'].url() }}">

</p>

"""
# install jinja2 templates
loader = jinja2.DictLoader({'index.html': template})
aiohttp_jinja2.setup(app, loader=loader)
# init routes for index page, and page with error
app.router.add_route('GET', '/', basic_handler, name='index')
app.router.add_route('GET', '/exc', exception_handler,
name='exc_example')
handler = app.make_handler()
srv = yield from loop.create_server(handler, '127.0.0.1', 9000)
print("Server started at http://127.0.0.1:9000")
return srv, handler
loop = asyncio.get_event_loop()
srv, handler = loop.run_until_complete(init(loop))
try:
loop.run_forever()
except KeyboardInterrupt:
loop.run_until_complete(handler.finish_connections())I've borrowed a lot of code from following projects. I highly recommend to check them out:
