我只是python的初学者,我不知道如何解决这个问题。请帮忙。
错误:
Traceback (most recent call last):
File "C:\Users\Priscilla\Desktop\CMPT Assn #3\page.py", line 17, in <module>
print "<p>Customer Name:", form["custName"].value, "</p>"
TypeError: 'classobj' object has no attribute '__getitem__'
Python脚本:
import cgi
form = cgi.FieldStorage
# print HTTP/HTML header stuff
print """Content-type: text/html
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">

<title>Order Form</title>
</head><body>
"""
# print HTML body using form data
print "<h1>Kintoro Japanese Bar & Restaurant</h1>"
print "<h2>Customer Reciept</h2>"
print "<p>Customer Name:", form["custName"].value, "</p>"
print "<p>Customer Email Address:", form["custEmail"].value, "</p>"
print "<h2>Customer Address:</h2>"

答案 0 :(得分:2)
form = cgi.FieldStorage
将班级FieldStorage
分配给form
。您想要分配FieldStorage
的实例:
form = cgi.FieldStorage()
答案 1 :(得分:1)
您不会实例化FieldStorage
。
你做了什么:form = cgi.FieldStorage
。这使form
等于类cgi.FieldStorage
。班级对你当前的要求一无所知。
你的意思是:form = cgi.FieldStorage()
。这将创建与当前请求关联的新实例。
答案 2 :(得分:0)
在python中调用[]
运算符会调用该对象的__getitem__(key)
方法。在您的情况下,似乎没有为form
是实例的类定义方法。
要解决此问题,您需要在相关类中定义方法及其行为。
