不理解requests.post传入参数请求是什么意思?
例如:
>>> import requests
>>> data = {
        'name':'LiLei'
        }
>>> response = requests.post('http://www.baidu.com',data=data)
>>> print(response.text)
这个响应结果可以正常返回的,太长了没有粘上

问题1:我想知道这个data数据传入百度网址什么地方了?是传入百度首页的输入框吗?
问题2:这个响应结果是百度输入框传入 name=LiLei   吗?然后点回车显示页面的审查元素吗?谢谢

把data上传到服务器。
建议去看一下Python爬取有道翻译那课,涉及到了有关知识。

网页请求分为get请求或是post请求,post请求你可以理解为发送了一串信息给网页,比如需要登录的网页就是用的post请求,发送给的信息就是我们输入的密码和账号。比如楼主你发的请求百度的链接用的request.post就是把data的数据发送给了百度,要求百度data里面的信息,你如果是用request.get则没有发送信息给百度,百度返回的是首页

mark一下,我也想知道,不知道楼上说的正确吗?因为百度好像只用get方法,不用post

data是上传到了百度的服务器,不是上传到百度网址的哪个地方。网页的作用是让用户更好的体验,它的背后也是数据的传输。看一下小甲鱼的《零基础学习web开发》就知道了。
你把返回的数据保存成一个网页文件,用浏览器打开。然后去百度首页输入框输入你刚刚提交的数据,对比两个网页就能知道的。
