Python I'；我对这样的网站感到困惑

好吧，这个网站只是一个例子，但我希望你能大致了解我的困惑

以下是我为该网站快速编写的代码：

payload = {'firstname': 'Ryanous', 'lastname': 'Smti','email': 'thingy7237@gmail.com', 'PASSWORD': 'yaya7893478934',}

r = requests.post(WHAT_URL??? , data = payload)
time.sleep(1.7834734)
print(r.content)

假设我正试图在这里（）注册Python请求。因此，当我查看网络选项卡以了解注册时会发生什么时，会发生3件事。当我键入我的名字和姓氏时，我键入的是发送给我的。当我键入我的电子邮件时，它也会发送到。当我输入密码时，网络控制台显示它只发送到。然而，当我发布到这些url的任何一个都不起作用。发生了什么事

提前感谢

这是发送到ebay的完整请求，被fiddler截获

从上面的原始请求可以看出，您需要将所有这些值发布到

https://reg.ebay.com/reg/PartialReg

。数据字典中的一些键可以从ebay的html页面源中提取

谢谢你的回答。如果我不得不反复发布这个有效负载呢？哪些信息（除了名/姓、电子邮件）需要更改？

tagInfo、ets、signInUrl

，只需检查页面源中隐藏的输入字段。我正在尝试使用BS4获取标记信息。但是在源代码中，我看不到标记信息的值。
