() { (::String) -> untyped } -> ::Hash[::String, ::Array[::String]]

() -> ::Enumerator[::String, ::Hash[::String, ::Array[::String]]]

each_capitalized_name() { |key| ... }

# File tmp/rubies/ruby-3.4.1/lib/net/http/header.rb, line 417
def each_capitalized_name  #:yield: +key+
  block_given? or return enum_for(__method__) { @header.size }
  @header.each_key do |k|
    yield capitalize(k)
  end
end

Calls the block with each capitalized field name:

Example

res = Net::HTTP.get_response(hostname, '/todos/1')
res.each_capitalized_name do |key|
  p key if key.start_with?('C')
end

Output:

Example

"Content-Type"
"Connection"
"Cache-Control"
"Cf-Cache-Status"
"Cf-Ray"

The capitalization is system-dependent; see Case Mapping.

Returns an enumerator if no block is given.
