花了 2 小時,粗略看了看 cgi.rb , cgi/session.rb 的代碼,終於得到了一點頭緒,終於免強地支援了 session 的輸出,不用再使用手冊上的那個方法,因為他一定要有 cgi.out 的輸出,而同時在 Block 內一定要有資料,資料長度不能為 “0”, 否則會出錯:
手冊上的 :

| require "cgi"
cookie = CGI::Cookie.new("rubyweb", "CustID=123", "Part=ABC");
cgi = CGI.new("html3")
cgi.out( "cookie" => [cookie] ){
cgi.html{
"\nHTML content here"
}
}
|
而我的方法只要這樣,必須大於零的條件刪去了,只要用以下的方法就可以

| require "cgi"
cookie = CGI::Cookie.new("rubyweb", "CustID=123", "Part=ABC");
cgi = CGI.new
cgi.out([cookie]) {""}
puts "nHTML content here"
|
簡化了很多東西,而且將 out 這個方法內處理日文 Charset 資料都刪除,我想效率會好一點,因為都用 utf-8 的 = =
