通过CGI程序传递下拉数据
HTML 下拉框代码如下：
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>菜鸟教程(runoob.com)</title>
</head>
<body>
<form action="/cgi-bin/dropdown.py" method="post" target="_blank">
<select name="dropdown">
<option value="runoob" selected>菜鸟教程</option>
<option value="google">Google</option>
</select>
<input type="submit" value="提交"/>
</form>
</body>
</html>
dropdown.py 脚本代码如下所示：
#!/usr/bin/python
# -*- coding: UTF-8 -*-
# 引入 CGI 处理模块
import cgi, cgitb
# 创建 FieldStorage的实例
form = cgi.FieldStorage()
# 接收字段数据
if form.getvalue('dropdown'):
dropdown_value = form.getvalue('dropdown')
else:
dropdown_value = "没有内容"
print "Content-type:text/html"
print
print "<html>"
print "<head>"
print "<meta charset=\"utf-8\">"
print "<title>菜鸟教程 CGI 测试实例</title>"
print "</head>"
print "<body>"
print "<h2> 选中的选项是：%s</h2>" % dropdown_value
print "</body>"
print "</html>"
修改 dropdown.py 权限：
chmod 755 dropdown.py
