调用CGI脚本文件的例子

//以下是mas_cvo.cpp文件

#include "t99_type.h"

#include

#include

inline void html( char str[] ) { cout << str << "\n"; }

inline void html_( char str[] ) { cout << str; }

inline void html_( char c ) { cout << c; }

// 传递调试选项

// 可以由脚本看到的环境变量

char* getenv_n( char var[] )

{

char *p = getenv( var );

return p == NULL ? (char*)"[]" : p;

}

void cgi_var_output( )

{

html("");

html("");

html( "

" );

html_("AUTH_TYPE "); html( getenv_n( "AUTH_TYPE" ) );

html_("CONTENT_LENGTH "); html( getenv_n( "CONTENT_LENGTH" ) );

html_("CONTENT_TYPE "); html( getenv_n( "CONTENT_TYPE" ) );

html_("GATEWAY_INTERFACE "); html( getenv_n( "GATEWAY_INTERFACE" ) );

html_("HOSTTYPE "); html( getenv_n( "HOSTTYPE" ) );

html_("HTTP_ACCEPT "); html( getenv_n( "HTTP_ACCEPT" ) );

html_("HTTP_CONNECTION "); html( getenv_n( "HTTP_CONNECTION" ) );

html_("HTTP_HOST "); html( getenv_n( "HTTP_HOST" ) );

html_("HTTP_PRAGMA "); html( getenv_n( "HTTP_PRAGMA" ) );

html_("HTTP_REFERER "); html( getenv_n( "HTTP_REFERER" ) );

html_("HTTP_USER_AGENT "); html( getenv_n( "HTTP_USER_AGENT" ) );

html_("OSTYPE "); html( getenv_n( "OSTYPE" ) );

html_("PATH_INFO "); html( getenv_n( "PATH_INFO" ) );

html_("PATH_TRANSLATED "); html( getenv_n( "PATH_TRANSLATED" ) );

html_("QUERY_STRING "); html( getenv_n( "QUERY_STRING" ) );

html_("REMOTE_ADDR "); html( getenv_n( "REMOTE_ADDR" ) );

html_("REMOTE_HOST "); html( getenv_n( "REMOTE_HOST" ) );

html_("REMOTE_IDENT "); html( getenv_n( "REMOTE_IDENT" ) );

html_("REMOTE_USER "); html( getenv_n( "REMOTE_USER" ) );

html_("REQUEST_METHOD "); html( getenv_n( "REQUEST_METHOD" ) );

html_("SCRIPT_NAME "); html( getenv_n( "SCRIPT_NAME" ) );

html_("SERVER_NAME "); html( getenv_n( "SERVER_NAME" ) );

html_("SERVER_PORT "); html( getenv_n( "SERVER_PORT" ) );

html_("SERVER_PROTOCOL "); html( getenv_n( "SERVER_PROTOCOL" ) );

html_("SERVER_SOFTWARE "); html( getenv_n( "SERVER_SOFTWARE" ) );

html("<P>");

html("Unix command printenv");

cout << flush;

system( "printenv | sort" );

html("");

html("Unix command set");

cout << flush;

system( "set | sort " );

html( "

" );

html( "" );

html( "" );

}

　　实际上，CGI脚本也可以用其它的语言来编写。如果你使用C语言来编写并且是在UNIX系统中，最好是使用版本高于2.7.0的gcc编译器，因为这个编译器支持新的数据类型：bool（布尔型）。
