我是Python的新手，所以请忍受我。。。 尝试对Instagram API进行一个简单的oAuth调用。注册应用程序后，您将获得客户端ID、客户端密码等，oAuth过程中的第一步是将用户定向到此授权URL：

https://api.instagram.com/oauth/authorize/?client_id=CLIENT-ID&redirect_uri=REDIRECT-URI&response_type=code

当我在带有客户机ID和重定向URL的浏览器中加载此URL时，浏览器中将显示以下URL（例如）：

^{pr2}$

我的问题是，如何使用请求模块复制浏览器中发生的事情？在

当我尝试以下操作时：

 >>> import requests
 >>> b = requests.get('https://api.instagram.com/oauth/authorize/?client_id=c918883453360349850498&redirect_uri=http://instagrram.myredirect.com/home.html&response_type=code')
 >>> b.text

我知道什么是不恰当的回答“我知道这是什么意思，我不该这样做”：

但是，当您将URL加载到浏览器中时，如何让请求只返回code:code=956237827314ee22092384984938？在

出于生产目的，您不应该重新实现oauth。请看一下https://pypi.python.org/pypi/oauthlib，这是一个用于执行oauth身份验证逻辑的已建立库。如果你想坚持使用requests，那么还有{a2}。除此之外，关于你的问题

My question is, how can I replicate what happens in the browser using the Requests module?

这不是小事。首先，使用curl或浏览器插件来调试/重建协议流。第二步是使用requests重建相同的流。在

示例：当通过GET访问问题中提到的第一个URL时，服务器用一个^{}进行响应，其目标在response头的Location字段中给出。响应还通过Set-Cookie头字段设置cookie。所有这些都很重要。在
