fastapi logging error and swagger is not working

Time:05-09

I'm making a rest api using fastapi.

I just wonder why I get below messages whenever I execute my server.

INFO:     Started server process [97154]
INFO:     Waiting for application startup.
INFO:     Application startup complete.
--- Logging error ---

Message: 'Uvicorn running on %s://%s:%d (Press CTRL C to quit)'
Arguments: ('http', '0.0.0.0', '8000')

And below is main.py.

import uvicorn as uvicorn

app = FastAPI()
# Skip some settings

if __name__ == '__main__':
    uvicorn.run(app, host='0.0.0.0', port='8000')

Also, I can't get anything in swagger and redocs whereas I can get REST methods' results.

Please help

CodePudding user response:

you need to change your port to int and app object to str like below simple code try it

if __name__ == "__main__":
    uvicorn.run("main:app", host="0.0.0.0", port=8000)
