The implementation of POST search support comes with a few benefits. The
most apparent is the avoidance of search queries appearing in web server
logs -- instead of the prior GET approach (i.e.
/search?q=my+search+query), using POST requests with the query stored in
the request body creates logs that simply appear as "/search".
Since a lot of relative links are generated in the results page, I came
up with a way to generate a unique key at run time that is used to
encrypt any query strings before sending to the user. This benefits both
regular text queries as well as fetching of image links and means that
web logs will only show an encrypted string where a link or query
string might slip through.
Unfortunately, GET search requests still need to be supported, as it
doesn't seem that Firefox (on iOS) supports loading search engines by
their opensearch.xml file, but instead relies on manual entry of a
search query string. Once this is updated, I'll probably remove GET
request search support.
Images were previously directly fetched from google search results,
which was a potential privacy hazard. All image sources are now modified
to be passed through shoogle's routing first, which will then fetch raw
image data and pass it through to the user.
Filter class was refactored to split the primary clean method into
smaller, more manageable submethods.
The image results page seems to have different formatting from non-image
results pages. Should probably revisit this at some point and try to
style the image results page to be more in line with other result types.
- Updated Dockerfile to include chmod of run script
- Added app.json for Heroku quick deploy
- Removed unused function var in js controller
- Moved requirements back to root of repo
- Added Codebeat report to readme
Curl requests and user agent related functionality was moved to its own
request class.
Routes was refactored to only include strictly routing related
functionality.
Filter class was cleaned up (had routing/request related logic in here,
which didn't make sense)
