Question

这是我在网上看到如何设置cookie的例子。

require "cgi"
cookie = CGI::Cookie.new("rubyweb", "CustID=123", "Part=ABC");
cgi = CGI.new("html3")
cgi.out( "cookie" => [cookie] ){
  cgi.html{
    "\nHTML content here"
  }
}

我尝试这样做，然后设置cookie，然后出现一个空白页。

#!/usr/local/bin/ruby

require 'cgi'
load 'inc_game.cgi'
cgi = CGI.new

cookie = CGI::Cookie.new("rubyweb", "CustID=123", "Part=ABC");
cgi.out( "cookie" => [cookie] ){""}     

#see if game submit buttons pressed
doIt = cgi['play']
puts "Content-type: text/html\n\n"  

play = Game.new

#welcome
if doIt == ''
puts play.displayGreeting
end

#choose weapon
play.playGame

if doIt == 'Play'
    move = cgi['weapon']
    human = play.humanMove(move)
    computer = play.ComputerMove
    print human
    print computer
    result = play.results(human,computer)
    play.displayResults(result)
end

所以我的问题首先是，我错过了什么/做错了什么？其次，我想知道是否有人想要解释什么.out与.header相反或是否存在差异？

谢谢，

我相信这一行：

cgi.out( "cookie" => [cookie] ){""}

正在刷出你的标题。

在我的TTY中运行代码

Content-Type: text/html
Content-Length: 0
Set-Cookie: rubyweb=CustID%3D123&Part%3DABC; path=

Content-type: text/html

被发出，“Content-Length：0”（由out {}中的空字符串生成）可能告诉浏览器你已经完成了。

cookie = CGI::Cookie.new("rubyweb", "CustID=123", "Part=ABC");
cgi.header( "cookie" => [cookie] ,  type => 'text/html' )

#normal printing here

最好发送标题。

选择'做处理' - '然后考虑输出'模型可能会有所帮助。

require 'cgi'
load 'inc_game.cgi'

cgi = CGI.new
cookie = CGI::Cookie.new("rubyweb", "CustID=123", "Part=ABC");

output = ""; 

#see if game submit buttons pressed
doIt = cgi['play']

play = Game.new

#welcome
if doIt == ''
  output << play.displayGreeting
end

#choose weapon
play.playGame

if doIt == 'Play'
    move = cgi['weapon']
    human = play.humanMove(move)
    computer = play.ComputerMove
    output << human
    output << computer
    result = play.results(human,computer)
    output << play.displayResults(result)
end



cgi.out( "cookie" => [cookie] , type=>"text/html" ){ 
  output; 
}

CGI cookie如何在Ruby中运行？
