使用erlang连接php的cgi处理方式(转)

天真的以为找到了最快的解决方案, 看了下代码发现虽然这种方式是利用 open_port,但所有的数据传输 居然用的是 ENV,我倒 玩玩可以,生产环境就是找死了. 其实作者的需求直接用ports 就好了,数据传输可以用 json

为了更好控制还是要走fastcgi 协议,继续改 yaws_cgi.erl. 在协议分析上绕的脑袋大了, 想玩erlang,而不被erlang玩还需要个漫长的过程... 从协议解析开始..

-module(test).

-export([cgi_worker/0]).

cgi_worker() ->

Env = [{"SERVER_SOFTWARE","test web server"},

{"SERVER_NAME","localhost"},

cgi_get_line({start, CGIPort}).

%%获取结果

cgi_get_line({start, Port}) ->

receive

{Port, {data,Data}} ->

io:fwrite("DATA:~p~n", [Data]);

{Port, {exit_status, 0}} ->

io:fwrite("~p~n", [{exit_status, 0}]);

{Port, {exit_status, Status}} when Status /=0 ->

io:fwrite("~p~n", [{exit_status, Status}]);

_Other ->

io:fwrite("~p~n", [_Other])

end.

php脚本

< ?php

echo 'ello php-cgi!';

? >

以上纯粹直接构造，使用时请根据每个人环境加以修改，编译后运行如下：

67> c(test).

{ok,test}

68> test:cgi_worker().

DATA:<<"X-Powered-By: PHP/5.2.6\r\nContent-type: text/html\r\n\r\nhello php-cgi!">>

ok

说明连接并执行成功，erlang以其强悍的网络并发处理(并非只谈性能)能力，加上php的脚本的简便，相信他们可以成为很好的互补。
