== NAME
cgi.rb - cgi support library
Version 2.1.2
Copyright (C) 2000 Network Applied Communication Laboratory, Inc.
Copyright (C) 2000 Information-technology Promotion Agency, Japan
Wakou Aoyama <wakou@fsinet.or.jp>
== EXAMPLE
=== GET FORM VALUES
require "cgi"
cgi = CGI.new
values = cgi['field_name'] # <== array of 'field_name'
# if not 'field_name' included, then return [].
fields = cgi.keys # <== array of field names
# returns true if form has 'field_name'
cgi.has_key?('field_name')
cgi.has_key?('field_name')
cgi.include?('field_name')
=== GET FORM VALUES AS HASH
require "cgi"
cgi = CGI.new
params = cgi.params
cgi.params is a hash.
cgi.params['new_field_name'] = ["value"] # add new param
cgi.params['field_name'] = ["new_value"] # change value
cgi.params.delete('field_name') # delete param
cgi.params.clear # delete all params
=== SAVE FORM VALUES TO FILE
require "pstore"
db = PStore.new("query.db")
db.transaction do
db["params"] = cgi.params
end
=== RESTORE FORM VALUES FROM FILE
require "pstore"
db = PStore.new("query.db")
db.transaction do
cgi.params = db["params"]
end
=== GET MULTIPART FORM VALUES
require "cgi"
cgi = CGI.new
values = cgi['field_name'] # <== array of 'field_name'
values[0].read # <== body of values[0]
values[0].local_path # <== path to local file of values[0]
values[0].original_filename # <== original filename of values[0]
values[0].content_type # <== content_type of values[0]
and values[0] has Tempfile class methods.
(Tempfile class object has File class methods)
=== GET COOKIE VALUES
require "cgi"
cgi = CGI.new
values = cgi.cookies['name'] # <== array of 'name'
# if not 'name' included, then return [].
names = cgi.cookies.keys # <== array of cookie names
and cgi.cookies is a hash.
=== GET COOKIE OBJECTS
require "cgi"
cgi = CGI.new
for name, cookie in cgi.cookies
cookie.expires = Time.now + 30
end
cgi.out("cookie" => cgi.cookies){"string"}
cgi.cookies # { "name1" => cookie1, "name2" => cookie2, ... }
require "cgi"
cgi = CGI.new
cgi.cookies['name'].expires = Time.now + 30
cgi.out("cookie" => cgi.cookies['name']){"string"}
and see MAKE COOKIE OBJECT.
=== GET ENVIRONMENT VALUE
require "cgi"
cgi = CGI.new
value = cgi.auth_type
# ENV["AUTH_TYPE"]
see http://www.w3.org/CGI/
AUTH_TYPE CONTENT_LENGTH CONTENT_TYPE GATEWAY_INTERFACE PATH_INFO
PATH_TRANSLATED QUERY_STRING REMOTE_ADDR REMOTE_HOST REMOTE_IDENT
REMOTE_USER REQUEST_METHOD SCRIPT_NAME SERVER_NAME SERVER_PORT
SERVER_PROTOCOL SERVER_SOFTWARE
content_length and server_port return Integer. and the others return String.
and HTTP_COOKIE, HTTP_COOKIE2
value = cgi.raw_cookie
# ENV["HTTP_COOKIE"]
value = cgi.raw_cookie2
# ENV["HTTP_COOKIE2"]
and other HTTP_*
value = cgi.accept
# ENV["HTTP_ACCEPT"]
value = cgi.accept_charset
# ENV["HTTP_ACCEPT_CHARSET"]
HTTP_ACCEPT HTTP_ACCEPT_CHARSET HTTP_ACCEPT_ENCODING HTTP_ACCEPT_LANGUAGE
HTTP_CACHE_CONTROL HTTP_FROM HTTP_HOST HTTP_NEGOTIATE HTTP_PRAGMA
HTTP_REFERER HTTP_USER_AGENT
=== PRINT HTTP HEADER AND HTML STRING TO $DEFAULT_OUTPUT ($>)
require "cgi"
cgi = CGI.new("html3") # add HTML generation methods
cgi.out() do
cgi.html() do
cgi.head{ cgi.title{"TITLE"} } +
cgi.body() do
cgi.form() do
cgi.textarea("get_text") +
