bottle-cors-plugin

The easiest way to implement CORS on your bottle py web application.

Installing the plugin

pip install bottle-cors-plugin

Then, on your bottle app import the cors_plugin and install it like so:

# -*- coding: utf-8 -*-
from bottle import app, response, route, run
from bottle_cors_plugin import cors_plugin

@route('/', method='GET')
def landing():
  response.content_type = 'application/json'
  return {'status': 'Works'}

#Confugure the server
app = app()
app.install(cors_plugin('*'))

if name == "__main__":
  run(host='localhost', port=7000)

The cors_plugin function accepts a string or an array of strings representing the allowed origins. Passing no origins to the function will assume '*', that is, all origins are allowed.

cors_plugin()

This will allow all origins ('*').

cors_plugin('https://google.com')

Allows just "https://google.com" as origin.

cors_plugin(['https://google.com', 'http://google.com'])

Is how you define multiple allowed origins.

Aborts

For regular abort errors you need to import the abort function from cors_plugin like so:

from bottle_cors_plugin import abort


@route('/', method='GET')
def landing():
  response.content_type = 'application/json'
  abort(500, 'Hola')
  return {'status': 'Internal error'}

It works with all errors, and if you need a custom error handler, use the cors_headers function like so:

# -*- coding: utf-8 -*-
from import_env import os
from bottle import error, response
from bottle_cors_plugin import cors_headers

error_log = error

for status_code in range(200, 600):
@error(status_code)
def errorCustom(error_log):
    cors_headers()
    error_log.content_type = 'application/json'
    return error_log.body
