erlang 连接php-fpm

前端时间在网上看见erlang 连接php-fpm的例子,自己跟到弄了一下,下面给我调试后的代码贴出来

我修正了原来代码的2处bug:

1、参数超过128字符出错

2、当php返回超过1024字节时候出错

文件名fastcgi.erl

                  

- module(fastcgi). - compile(export_all).do_request(Argv) -> Env = [ { " SCRIPT_FILENAME " , " E:/phpGame/game/gateway.php " }, { " websocket " ,Argv} ], io:format( " Argv msg: ~ts~n " , [Argv]), {ok, Socket} = gen_tcp:connect( " 127.0.0.1 " , 9000 ,[binary, {packet, 0}, {active,true}], 10000 ), fcgi_send_record(Socket, 1 , 1 , > ), fcgi_send_record(Socket, 4 , 1 , Env), fcgi_send_record(Socket, 4 , 1 , []), Bin = phpRespone(Socket,[]), gen_tcp:close(Socket), %% 原报文 > = Bin, > = Bin, %% 计算输出内容长度 Dlen = ContentLength - 52 , %% 获取内容 > = Str, io:fwrite( " rs:~p~n " ,[Data]), {ok,Data}.recv_msg(Sock) -> receive {tcp, Sock, Bin} -> io:format( " Bin msg: ~p~n " , [Bin]), %% 原报文 > = Bin, > = Bin, %% 计算输出内容长度 Dlen = ContentLength - 52 , %% 获取内容 > = Str, io:fwrite( " rs:~p~n " ,[Data]), {ok,Data}; {tcp_closed,Sock} -> io:format( " socket close: ~p~n " , [Sock]); _Other -> io:format( " Other msg: ~p~n " , [_Other]), recv_msg(Sock) after 3000 -> io:format( " Time out.~n " ) end. phpRespone(Sock,SoFar) -> receive {tcp, Sock, Bin} -> phpRespone(Sock,[Bin | SoFar]); {tcp_closed,Sock} -> list_to_binary(lists:reverse(SoFar)); _Other -> io:format( " Other msg: ~p~n " , [_Other]), phpRespone(Sock,SoFar) after 3000 -> io:format( " Time out.~n " ) end. %% 发送选项 fcgi_send_record(Socket, Type, RequestId, NameValueList) -> EncodedRecord = fcgi_encode_record(Type, RequestId,NameValueList), gen_tcp:send(Socket, EncodedRecord). %% 组包 fcgi_encode_record(Type, RequestId, NameValueList) when is_list(NameValueList) -> fcgi_encode_record(Type, RequestId,fcgi_encode_name_value_list(NameValueList)); %% 判断ContentData是否满8字节,否则填充 fcgi_encode_record(Type, RequestId, ContentData) when is_binary(ContentData) -> ContentLength = size(ContentData), PaddingLength = if ContentLength rem 8 == 0 -> 0; true -> 8 - (ContentLength rem 8 ) end, %% 填充数据,每8字节组包 不足用0填充 PaddingData = > , Version = 1 , Reserved = 0, > . %% 将环境变量组成binary fcgi_encode_name_value_list(_NameValueList = []) -> > ; fcgi_encode_name_value_list(_NameValueList = [{Name, Value} | Tail]) -> > . fcgi_encode_name_value(Name, _Value = undefined) -> fcgi_encode_name_value(Name, "" ); fcgi_encode_name_value(Name, Value) when is_list(Name) and is_list(Value) -> NameSize = length(Name), NameSizeData = > , ValueSize = length(Value), if ValueSize ValueSizeData = > ; ValueSize > 127 -> ValueSizeData = > end, > .

在windows 下启动php cgi可以这样做

php-cgi.exe -b 127.0.0.1:9000

在erlang shell中调用:

2> c(fastcgi).
{ok,fastcgi}
3> fastcgi:do_request("{'uid':1}").
