我对POST这样的网站很困惑

Question

好吧所以这个网站只是一个例子，但我希望你对我困惑的一般概念有所了解。

这是我为网站快速写的代码：

payload = {'firstname': 'Ryanous', 'lastname': 'Smti','email': '[email protected]', 'PASSWORD': 'yaya7893478934',}

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

所以，我想说我正在尝试使用Python请求在这里注册（https://reg.ebay.com/reg/PartialReg）。因此，当我查看“网络”选项卡时，看看当我注册3件事情时会发生什么。当我输入我输入的名字和姓氏时，我输入的内容将被发送到https://reg.ebay.com/reg/track。当我输入我的电子邮件时，它会发布到https://reg.ebay.com/reg/track以及https://reg.ebay.com/reg/ajax。当我输入密码时，网络控制台显示它只发布到https://reg.ebay.com/reg/ajax。但是，当我发布到任何这些网址时，它不起作用。到底是怎么回事？

提前致谢！！！

从上面的原始请求中可以看出，您需要将所有这些值POST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。
