Creating URL-encoded URLs in Falcon web framework
- Aug 02, 2023
REST APIs can pass another URL as part of the API’s URL. E.g., /cache/foo%2Fbar.html is passing foo/bar.html to /cache/ endpoint. Building these APIs in Python is difficult because of the unfortunate omission of the WSGI specification that doesn’t provide the means to access the raw request URL. WSGI offers web frameworks only already URL-decoded PATH_INFO CGI variable. I.e., for the previous example, they actually got /cache/foo/bar.html which likely leads to 404 Not Found as there is no cache/foo/bar.html endpoint.
Centralized user messages in Python apps

Helpful errors with error codes. Do you love it too? During the development of the Snippets, an online preview tool for reStructuredText (and Markdown coming soon), I tried to produce actually helpful messages to the API user. I started with collecting text strings that could appear to users across the codebase and put them into a single file.
