bottle

requests

request.headers

type bottle.WSGIHeaderDict is different from dict

Troubleshooting

Object of type "ModuleType" is not callable

Pyright cannot infer correct type for Bottle()
In VSCodium, in settings, uncheck Workspace/UseLibraryCodeForTypes

Debug

Debugging a Bottle (or Flask) application underlies that a process can handle request and call route handlers.
To do so, a solution is to create a simple app:

from bottle import Bottle
import io
import json

import somewhere


def add_route(app, route, method, fn):
    app.route(route, method, fn)
    return app


def request_post(app, fn, data):
    add_route(app, '/', 'POST', fn)
    post = json.dumps(data).encode()
    # content_length is crucial
    request_data = {
        'REQUEST_METHOD': 'POST',
        'PATH_INFO': '/',
        'CONTENT_TYPE': 'application/json',
        'wsgi.input': io.BytesIO(post),
        'CONTENT_LENGTH': str(len(post))
    }
    return app.wsgi(request_data, lambda *args: None)


def request_user_login_create(app):
    fn = somewhere.v1_user_login_create
    data = {
        'USER_LOGIN': 'john.smith@unknown-llp.com'
    }
    return request_post(app, fn, data)


app = Bottle()
request_user_logincreate(app)
