我已经设置了这个简单的网站，上面只有一个表单，所以我可以用Python来练习填写：http://www.wix.com/yoshyaro/status-check。
查看urllib2 - The Missing Manual，我的代码配置如下
url = 'http://www.wix.com/yoshyaro/status-check'
values = {'name':"my name",
'email':"yoshyaro@yahoo.com",
'subject':"Subject",
'Message':"Hello"}
data = urllib.urlencode(values)
req = urllib2.Request(url, data)
response = urllib2.urlopen(req)
the_page = response.read()
当我理解这个代码可以工作时，我们正在向服务器发送一个POST请求，其中包含请求中打包的所有表单数据。但是，我正在使用的方法必须做错，因为没有发生任何事情。我没有收到任何确认电子邮件。
因此，我手动填写表单，点击提交，然后查看Chrome的网络标签。我看到一个POST请求，其中包含以下信息。

我注意到的第一件事是请求URL与我设置的URL不同。所以我将我的代码更改为：
url = 'http://editor.wix.com/wixpress/sendEmail.jspx'
values = {'name':"my name",
'email':"yoshyaro@yahoo.com",
'subject':"Subject",
'Message':"Hello"}
data = urllib.urlencode(values)
req = urllib2.Request(url, data)
response = urllib2.urlopen(req)
the_page = response.read()
但是运行它会产生HTTP 403错误：禁止。现在假设我正在尝试做的就是以适当的方式重新创建HTTP请求，我开始再次查看“网络”选项卡以查看这样的请求到底是什么样的。我此时的计划是尝试手工重建。但是，这就是我被困住的地方。我没有看到任何与POST请求中的实际内容有关的信息。我看到输出是什么，“[name]已发送消息”在POST发布后显示，但我无法在任何地方找到任何实际的表单值。
所以我就是这样。我不确定如何重新创建POST请求，因为我不确定它甚至是什么样的..
