「嘞是web」

Lessweb is an extremely easy-to-use python web framework with the following goals.

• Simple and efficient: based on the aiohttp library IOC capabilities, native support for configuration loading and logging settings to meet production-level development requirements
• Pythonic: support for the latest python version and the latest python syntax

To install the latest lessweb for Python 3, please run:

pip3 install lessweb

Save the code below in file index.py:

from lessweb import Bridge, get_mapping

@get_mapping('/')
async def hello():
    return {'message': 'Hello, world!'}

def main():
    bridge = Bridge()
    bridge.add_route(hello)
    bridge.run_app()

if __name__ == '__main__':
    main()

Start the application with the command below, it listens on http://localhost:8080/ by default.

python3 index.py

Save the code below in file config.toml:

[bootstrap]
port = 80

Then change the code to:

def main():
    bridge = Bridge(config='config.toml')
    bridge.add_route(hello)
    bridge.run_app()

Once you run it, you can access http://localhost/ with your browser.

You can also use environment variables to override the configuration file's contents, e.g. run BOOTSTRAP_PORT=8081 python3 index.py, then it listens on http://localhost:8081.
