基于Tomcat7.0版本号配置CGI开发环境,步聚例如以下:
以我的Tomcat7安装文件夹为例:TOMCA_HOME = /Users/yangxin/Documents/devToos/java/apache-tomcat-7.0.39
1、打开TOMCA_HOME/conf/web.xml
将CGI的Serlvet配置与URL映射凝视打开
<servlet>
<servlet-name>cgi</servlet-name>
<servlet-class>org.apache.catalina.servlets.CGIServlet</servlet-class>
<init-param>
<param-name>debug</param-name>
<param-value>0</param-value>
</init-param>
<init-param>
<param-name>executable</param-name>
<param-value></param-value>
</init-param>
<init-param>
<param-name>cgiPathPrefix</param-name>
<param-value>WEB-INF/cgi</param-value>
</init-param>
<load-on-startup>5</load-on-startup>
</servlet>
<!-- The mapping for the CGI Gateway servlet --> <servlet-mapping>
<servlet-name>cgi</servlet-name>
<url-pattern>/cgi-bin/*</url-pattern>
</servlet-mapping>
CGI Servlet初始化參数说明:
1> cgiPathPrefix:设置cgi程序在应用中的訪问位置,默认訪问位置为:应用名称/WEB-INF/cgi
2> executable:CGI程序解析器,默觉得perl。假设为空。能够是不论什么安装在操作系统环境变量的脚本解析器,或是C/C++程序
3> parameterEncoding:訪问CGI Servlet的默认參数编码,默觉得utf-8
4> passShellEnvironment:是否开启shell环境变量。默觉得false
5> stderrTimeout:读取标准错误信息超时时长,默觉得2000毫秒
2、打开TOMCAT_HOME/conf/context.xml
在context节点上加入一个属性privileged=true
<Context privileged="true"> <!-- Default set of monitored resources -->
<WatchedResource>WEB-INF/web.xml</WatchedResource> <!-- Uncomment this to disable session persistence across Tomcat restarts -->
<!--
<Manager pathname="" />
--> <!-- Uncomment this to enable Comet connection tacking (provides events
on session expiration as well as webapp lifecycle) -->
<!--
<Valve className="org.apache.catalina.valves.CometConnectionManagerValve" />
--> </Context>
3、创建CGI測试程序
在TOMCAT_HOME/webapps文件夹下创建建一个应用,如:cgitest,在cgitest应用下创建一个WEB-INF文件夹。在WEB-INF文件夹下创建一个cgi文件夹和一个web.xml文件,然后在cgi文件夹加入一个CGI測试脚本程序hello.sh和a.c并编译成a.cgi,并改动訪问权限。
随后启动tomcat。訪问http://localhost:8080/cgitest/cgi-bin/hello.sh就能够訪问自己写的CGI程序了
创建好的应用文件夹结构例如以下所看到的:
web.xml:
<?xml version="1.0" encoding="ISO-8859-1"?> <web-app xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
version="3.0"
metadata-complete="true"> <display-name>Welcome to Tomcat</display-name>
<description>
Welcome to Tomcat
</description> </web-app>
hello.sh:
#!/bin/sh
echo "Content-type:text/html\n\n"
echo "hello world"
a.c
#include <stdlib.h>
#include <stdio.h> int main(int argc, const char** args)
{
printf("Content-type:text/html\n\n");
printf("i is cgi programe");
return 0;
}
測试结果:
