Module | ActionDispatch::Http::FilterParameters |
In: |
lib/action_dispatch/http/filter_parameters.rb
|
Allows you to specify sensitive parameters which will be replaced from the request log by looking in all subhashes of the param hash for keys to filter. If a block is given, each key and value of the parameter hash and all subhashes is passed to it, the value or key can be replaced using String#replace or similar method.
Examples:
env["action_dispatch.parameter_filter"] = [:password] => replaces the value to all keys matching /password/i with "[FILTERED]" env["action_dispatch.parameter_filter"] = [:foo, "bar"] => replaces the value to all keys matching /foo|bar/i with "[FILTERED]" env["action_dispatch.parameter_filter"] = lambda do |k,v| v.reverse! if k =~ /secret/i end => reverses the value to all keys matching /secret/i
