相同的请求在 Fiddler 中有效，但在 Request 中无效

Question

我正在尝试使用请求从 Python 编辑我的 Instagram 个人资料。我可以轻松登录并执行 follows/etc，但我无法编辑个人资料。我不断收到 403 错误或 400 错误。当我漂亮地打印我的 Python 原始请求时，它看起来像这样（这些是我的虚拟帐户的 cookie）：

我的 POST 数据正文：

 first_name=888&email=ml162uju%40email.org&
 username=6relvwyv&phone_number=&gender=1&biography
 =&external_url=&chaining_enabled=on400

当我通过 fiddler 发送这个确切的请求时它有效，我得到 200，但是通过 Python 我得到 403 或 400。我尝试将数据作为原始字符串和字典发送，但两者都 return 错误。

Answer 1

尝试将 cookie 传递给请求模块以及 headers（尝试使用和不使用）

import http.cookies

str_cookies = """mid=W1WlVQALAAEfLNtIlXn2CtR3XAUF; ig_cb=1; mcd=3; ds_user_id=8271265936; sessionid=IGSCad223c2888974f0472cea36f316b1d3caab2feaa3bf519fa3652da183dca2446%3ARItc316HmDIUvwjI8BOJCzyvuFkHbeXd%3A%7B%22_auth_user_id%22%3A8271265936%2C%22_auth_user_backend%22%3A%22accounts.backends.CaseInsensitiveModelBackend%22%2C%22_auth_user_hash%22%3A%22%22%2C%22_platform%22%3A4%2C%22_token_ver%22%3A2%2C%22_token%22%3A%228271265936%3AXMCx3bjvUtWEy3A37cDnQiQ9ysQBaGw9%3A5aaef5c33915c937439a14292048d8ae0555d5bf949befcd5a9a8a209808e7c9%22%2C%22last_refreshed%22%3A1532306445.4836139679%7D; rur=PRN; urlgen="{\"time\": 15322952224 \"88.196.120.23\": 32494 \"2001:7d0:8b1b:d80:59ac:b6fd:fc77:754f\": 3249}:1fhOwz:lMzBvH8bTYwoOqWauglUMXbkGCU"""\
cookie_object = http.cookies.SimpleCookie(str_cookies)
cookies = {}
for key, morsel in cookie_object.items():
    cookies[key] = morsel.value

requests.post(.... , cookies=cookies)

我建议您使用这个 instagram_private_api python 模块，它已经实现了您可能需要的大部分方法，而不是您自己构建它
