c/c++写cgi之helloworld

最近比较闲,所以又回头来学习下c/c++, 但看来看去也没什么好学的,没什么项目,光学一门语言确实没什么好看的,那就来用c/c++写个cgi来玩玩吧,之前没做过cgi,所以这样就既可了解cgi又可复习c/c++了。

先来个c/c++的cgi hello world吧,本人是在apache下运行的啊

新建文件hello.c

#include <stdio.h>
main() {
    printf("Content-type:text/html\n\n");
    printf("Hello,World!");
}

用命令$gcc –o hello hello.c 生成 hello

然后查看apache配置文件httpd.conf, 设置为:[默认的差不多就是这样]

ScriptAlias /cgi-bin/ "/var/www/cgi-bin/"
<Directory "/var/www/cgi-bin">
    AllowOverride All
    Options ExecCGI
    Order allow,deny
    Allow from all
</Directory>

然后把生成的hello复制到 /var/www/cgi-bin/下,如果修改了配置的话,就先重起apache, 这时输入http://localhost/cgi-bin/hello,就应该可以看到结果了
