Question

我正在尝试运行以下程序：

#!/Python33/python
# Demonstrates get method with an XHTML form.

import urllib.parse
import cgi
import cgitb
import html
cgitb.enable()

def printHeader( title ):
    print("Content-type: text/html; charset=utf-8")
    print()
    print("<html>")
    print("<head><title>Test</title></head>")
    print("<body>")
    print(title)
    print("</body>")
printHeader( "Using 'get' with forms" )
print ('''<p>Enter one of your favorite words here:<br /></p>
    <form method = "get" action = "method.py">
        <p><input type = "text" name = "word"/>
        <input type = "submit" value = "Submit word"/>
        </p>
   </form>''')
pairs = cgi.parse();
if pairs.has_key("word"):
    print ('''<p>Your word is:
        <span style = "font-weight: bold">%s</span></p>''') \
    % html.escape( pairs[ "word" ][ 0 ] )
print ("</body></html>")
print()

当我运行它时，我收到以下错误：

    22         </p>
    23    </form>''')
=>  24 pairs = cgi.parse();
    25 if pairs.has_key("word"):
    26     print ('''<p>Your word is:
pairs undefined, cgi = <module 'cgi' from 'C:\\Program Files (x86)\\Apache Software Foundation\\Apache2.2\\htdocs\\cgi.py'>, cgi.parse undefined
AttributeError: 'module' object has no attribute 'parse' 
     args = ("'module' object has no attribute 'parse'",) 
     with_traceback = <built-in method with_traceback of AttributeError object>

我使用的是Python 3.3，我找不到是否应该使用cgi.parse()的替代品。

Answer 1

cgi.parse() exists in Python 3.3.你已经调用了一些其他文件“cgi.py”，Python正在寻找它。重命名该文件和任何相关的.py [co]文件。

Answer 2

cgi.parse exists in python 3.3，但你有一个名为cgi.py的python文件，它正在找到它。

以下是命名错误的cgi.py文件所在的位置：

<module 'cgi' from 'C:\\Program Files (x86)\\Apache Software 
Foundation\\Apache2.2\\htdocs\\cgi.py'>

python 3.3 does not have "has_key" though ...

所以你会在这一行上收到错误：

if pairs.has_key("word"):

将其更改为：

if "word" in pairs:

让代码正常运行。

输出：

Content-type: text/html; charset=utf-8
<html>
<head><title>Test</title></head>
<body>
Using 'get' with forms
</body>
<p>Enter one of your favorite words here:<br /></p>
    <form method = "get" action = "method.py">
        <p><input type = "text" name = "word"/>
        <input type = "submit" value = "Submit word"/>
        </p>
   </form>
</body></html>

在Python 3中是否有等效的cgi.parse（）
