Public Class Methods

allValuesAreStrings(hash) click to toggle source

Determines whether all values in a Hash are strings.

# File lib/akita/har_logger/har_utils.rb, line 48
def self.allValuesAreStrings(hash)
  hash.each do |_, value|
    if !(value.is_a? String) then
      return false
    end
  end

  return true
end
fixEncoding(v) click to toggle source

Rack apparently uses 8-bit ASCII for everything, even when the string is not 8-bit ASCII. This reinterprets 8-bit ASCII strings as UTF-8.

If we are unable to do this reinterpretation, return the string unchanged, but log a warning that points to the caller.

# File lib/akita/har_logger/har_utils.rb, line 11
def self.fixEncoding(v)
  if v == nil then
    return v
  end

  if !(v.is_a? String) then
    Rails.logger.warn "[#{caller_locations(1, 1)}] fixEncoding was not given a string. This might cause JSON serialization to fail."
    return v
  end

  # Only re-interpret 8-bit ASCII.
  if v.encoding != Encoding::ASCII_8BIT then
    return v
  end

  forced = String.new(v).force_encoding(Encoding::UTF_8)
  if forced.valid_encoding? then
    return forced
  end

  Rails.logger.warn "[#{caller_locations(1, 1)}] Unable to fix encoding: not a valid UTF-8 string. This will likely cause JSON serialization to fail."
  v
end
hashToList(hash) click to toggle source

Converts a Hash into a list of Hash objects. Each entry in the given Hash will be represented in the output by a Hash object that maps 'name' to the entry's key and 'value' to the entry's value.

# File lib/akita/har_logger/har_utils.rb, line 38
def self.hashToList(hash)
  hash.reduce([]) { |accum, (k, v)|
    accum.append({
      name: fixEncoding(k),
      value: fixEncoding(v.to_s),
    })
  }
end
