Net::HTTPHeader
The HTTPHeader module defines methods for reading and writing HTTP headers.
It is used as a mixin by other classes, to provide hash-like access to HTTP header values. Unlike raw hash access, HTTPHeader provides access via case-insensitive keys. It also provides methods for accessing commonly-used HTTP header values in more convenient formats.
Public Instance Methods
[](key)
click to toggle source
Returns the header field corresponding to the case-insensitive key. For example, a key of “Content-Type” might return “text/html”
# File net/http/header.rb, line 37
def [](key)
a = @header[key.downcase.to_s] or return nil
a.join(', ')
end
[]=(key, val)
click to toggle source
Sets the header field corresponding to the case-insensitive key.
# File net/http/header.rb, line 43
def []=(key, val)
unless val
@header.delete key.downcase.to_s
return val
end
set_field(key, val)
end

Adds a value to a named header field, instead of replacing its value. Second argument
valmust be a String. See also []=, [] and get_fields.request.add_field 'X-My-Header', 'a' p request['X-My-Header'] #=> "a" p request.get_fields('X-My-Header') #=> ["a"] request.add_field 'X-My-Header', 'b' p request['X-My-Header'] #=> "a, b" p request.get_fields('X-My-Header') #=> ["a", "b"] request.add_field 'X-My-Header', 'c' p request['X-My-Header'] #=> "a, b, c" p request.get_fields('X-My-Header') #=> ["a", "b", "c"]
