按照顺序从CGI开始入手
Ruby CGI Doc:
The Common Gateway Interface (CGI) is a simple protocol for passing an HTTP request from a web server to a standalone program, and returning the output to the web browser. Basically, a CGI program is called with the parameters of the request passed in either in the environment (GET) or via $stdin (POST), and everything it prints to $stdout is returned to the client.
这个类重点在于process!方法:
(1)
mark_features!
def mark_features!
@features = $".clone
end
// 通过 $" 得到Rails加载的所有.rb文件名组成的list
(2)
process_each_request
(3) process_request
4) with_signal_handler
def with_signal_handler(signal)
install_signal_handler(signal)
yield
ensure
install_signal_handler(signal, 'DEFAULT')
end
5) install_signal_handler
这个方法实际上是将各个handler方法和一些signal绑定,
这些信号发送后就会调用各个handler
接下来就到Dispatcher里面了
