Flask-Cors 1.2.0

A Flask extension adding a decorator for CORS support

Flask-CORS is a simple extension to Flask allowing you to support cross origin resource sharing (CORS) using a simple decorator.

Installation

Install the extension with using pip, or easy_install.

$ pip install flask-cors

Usage

This extension exposes a simple decorator to decorate flask routes with. Simply add @cross_origin() below a call to Flask’s @app.route(..) incanation to accept the default options and allow CORS on a given route.

Simple Usage

@app.route("/")
@cross_origin() # allow all origins all methods.
def helloWorld():
  return "Hello, cross-origin-world!"

Using defaults

Alternatively, setting your application’s CORS_ORIGINS configuration property will

app.config['CORS_ORIGINS'] = ['Foo', 'Bar']
@app.route("/")
@cross_origin() # will return CORS headers for origins 'Foo' and 'Bar'
def helloWorld():
  return "Hello, cross-origin-world!"

For a full list of options, please see the full documentation

Tests

A simple set of tests is included in test.py. To run, install nose, and simply invoke nosetests or run python test.py to exercise the tests.
