Question

我有一个upload.php页面，它通过表单将一些数据发送到Python CGI脚本，然后我在后台处理数据，我想重定向到另一个php页面，response_page.php，它显示基于的信息处理过的数据。我不能将数据发送回PHP并同时进行重定向。

我的代码：

#!/usr/bin/env python

import cgi
import cgitb
cgitb.enable()

try:
    form = cgi.FieldStorage()
    fn = form.getvalue('picture_name')
    cat_id = form.getvalue('selected')
except KeyError:
    print "Content-type: text/html"
    print
    print "<html><head>"
    print "</head><body>error</body></html>"
else:
    ...
    # here I processed the form data and stored it in data_to_be_displayed 
    # data to be processed and displayed in the response page
    data_to_be_displayed = [1,2,3]

    import httplib, json, urllib
    headers = {'Content-type': 'application/json', 'Accept': 'text/plain'}
    conn = httplib.HTTPConnection('192.168.56.101:80')
    #converting list to a json stream
    data_to_be_displayed = json.dumps(data_to_be_displayed, ensure_ascii = 'False')
    postData = urllib.urlencode({'matches':data_to_be_displayed})
    conn.request("POST", "/response_page.php", postData, headers)
    response = conn.getresponse()

    if response.status == 200:
        print "Location: /response_page.php"
        print # to end the CGI response headers.

    conn.close()

我发现了这个：How to make python urllib2 follow redirect and keep post method，但我不明白我应该如何在我的代码中使用urllib2.HTTPRedirectHandlerClass。

为什么不使用liburl2发布到response_page.php？

import urllib
import urllib2
headers = {'Content-type': 'application/json', 'Accept': 'text/plain'}
data_to_be_displayed = json.dumps(data_to_be_displayed, ensure_ascii = 'False')
postData = urllib.urlencode({'matches':data_to_be_displayed})
req = urllib2.Request(url, data, headers)
response = urllib2.urlopen(req)
the_page = response.read()

作为参考，我使用了蟒蛇的想法＆＃39;文件：

您也可以考虑将Twisted apt用于更高级别的代码：

在更好地了解您的要求之后，我发现这篇文章提到重定向307完全是您想要的（如果我现在理解的话）：
