问题 I have a tool that I am working on and I need it to run a parser and also output another analysis log. Currently I have it so that it's through a web interface. User goes to the form and submits a filename for parsing (file already on system). Form submits information to Python CGI script Python CGI script runs and spawns a subprocess to run the parsing. Parser finds appropriate information for analysis and spawns subprocess also. I am using import subprocess ... subprocess.Popen(["./program

一直对这四者的概念和区别很模糊，现在就特意梳理一下它们的关系与区别。 CGI CGI即通用网关接口(Common Gateway Interface)，是外部应用程序（CGI程序）与Web服务器之间的接口标准，是在CGI程序和Web服务器之间传递信息的规程。CGI规范允许 Web服务器执行外部程序，并将它们的输出发送给Web浏览器，CGI将Web的一组简单的静态超媒体文档变成一个完整的新的交互式媒体。通俗的讲CGI 就像是一座桥，把网页和WEB服务器中的执行程序连接起来，它把HTML接收的指令传递给服务器的执行程序，再把服务器执行程序的结果返还给HTML页。 CGI 的跨平台性能极佳，几乎可以在任何操作系统上实现。 CGI方式在遇到连接请求（用户请求）先要创建cgi的子进程，激活一个CGI进程，然后处理请求，处理完后结束这个子进程。这就是fork- and-execute模式。所以用cgi方式的服务器有多少连接请求就会有多少cgi子进程，子进程反复加载是cgi性能低下的主要原因。当用户请求数 量非常多时，会大量挤占系统的资源如内存，CPU时间等，造成效能低下。 CGI脚本工作流程： 浏览器通过HTML表单或超链接请求指向一个CGI应用程序的URL。 服务器收发到请求。 服务器执行所指定的CGI应用程序。 CGI应用程序执行所需要的操作，通常是基于浏览者输入的内容。

How can I set Perl's inclusion path for modules for a CGI script?

问题 I’ve got several Perl modules installed on my hosting machine in ~/perl , how do I add them to Perl module path? Setting PERL5LIB or unshift ing the paths to @INC surely works, but the environment variable does not help when running as a CGI script and the @INC way is not very portable. Is there a better way? This has to be a common problem, am I missing something? 回答1: PERL5LIB works just fine for CGI scripts. You just have to set the variable in the right place, such as the server

Apache2 sends two HTTP headers with a mapped “nph-” CGI

由 假装没事ソ 提交于 2019-12-19 08:58:25
问题 Summary I'm trying to map some file extensions to be executed by a nph (Non Parsed Header) CGI executable. Let's say I want to access a URL http://server/file.ext and map the "ext" file extension to "trigger" the execution of my nph CGI (/var/www/cgi-bin/nph-test.sh). Apache configuration To do that I'm using mod_actions and mod_cgid, this is my relevant configuration information: <VirtualHost *:80> DocumentRoot /var/www/htdocs ScriptAlias /cgi-bin /var/www/cgi-bin Action cgi-wrapper /cgi-bin

Calling exec returns errno 14 (bad address) with absolute path

问题 in making a simple cgi server for a course. To do that in some point I have to make a fork/exec to launch the cgi handler, the problem is that the exec keep returning errno 14. I've tried the following code in a standalone version an it works with and without the absolute path. Here's the code: static void _process_cgi(int fd, http_context_t* ctx) { pid_t childProcess; int ret; char returnValue[1024]; log(LOG, "calling cgi", &ctx->uri[1], 0); if((childProcess = fork()) != 0) { /// /// Set the
