Google App Engine Static Website Redirect Trailing Slash

This page is about static website hosting and redirect pages like /about to /about/.

Sadly, redirect configuration is not possible using app.yaml, but it can be used with a combination of coding to achieve the same result.

Edit app.yaml.

handlers:# file with extensions (longer cache period)- url: /(.*\.(css|js|woff|woff2|ico|png))  static_files: www/\1  upload: www/(.*)  expiration: "7d"  secure: always# file with other extensions (e.g. .html)- url: /(.*\..*)  static_files: www/\1  upload: www/(.*)  secure: always# assume file without extensions use default index.html- url: /(.*)/  static_files: www/\1/index.html  upload: www/(.*)/index.html  secure: always# home- url: /  static_files: www/index.html  upload: www/index.html  secure: always# access without trailing slash- url: /(.*)  script: mini.app

Create file mini/__init__.py.

This file will redirect pages like /about to /about/.

from flask import Flask, abortapp = Flask(__name__)@app.route('/<path:path>/')def redirect(path):    # will never reach this code, as /path/ is intercepted at app.yaml    abort(404)

NOTE: I make use of flask routing feature to redirect pages without trailing slash to one with trailing slash, but you could use other methods which you are comfortable with.

NOTE: Refer to Flask On Google App Engine
