This gem prevents #to_json calls from raising exceptions on strings that are not UTF-8 encoded. It was written to deal with logging failures in the logstasher gem.
The exceptions were JSON::GeneratorError and
Encoding::UndefinedConversionError and occurred when trying to log
controller parameters that contained ASCII-8BIT strings. You can
reproduce these errors on a running app using the following curl
command:
curl -i -X GET "http://localhost:3000/tests" -d $'param=a\xE2a'See the specs for a typical example string.
Add this line to your application's Gemfile:
gem 'string_scrubber'And then execute:
$ bundle
Or install it yourself as:
$ gem install string_scrubber
Install it. It does the rest.
After checking out the repo, run bin/setup to install dependencies. Then, run rake rspec to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.
To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.
