【中文标题】Python 请求 POST DATA 错误 400 标头名称无效【英文标题】：Python Requests POST DATA Error 400 Header name invalid 【发布时间】：2018-09-04 16:41:14 【问题描述】：我想向这个 URL 发送一个发布数据请求：https://www.createsend.com/t/securedsubscribe?token=" + token 每次令牌都在变化，但我想办法找回它。但我无法访问网站
当我在 Chrome 控制台中检查时，会使用此标头。

此网页使用 H2 协议。所以我使用 Hyper 模块通过低谷：
session.mount("https://www.createsend.com",HTTP20Adapter())
r = session.post(url , data=payload2 , headers=header2)
print(r.text)
但我仍然收到此错误。
<HTML><HEAD><TITLE>Bad Request</TITLE>
<META HTTP-EQUIV="Content-Type" Content="text/html; charset=us-ascii"></HEAD>
<BODY><h2>Bad Request - Invalid Header</h2>
<hr><p>HTTP Error 400. The request has an invalid header name.</p>
</BODY></HTML>
我要提交的网站表单：http://tres-bien.com/odehhasoidj，您可以在其中查看发出了哪些 POST 请求
这是我的代码

【问题讨论】：
【参考方案1】：没有足够的信息可以告诉，但authority、scheme等是特殊头，必须以冒号为前缀，如:authority、:scheme、等等
请在此处查看“伪标题字段”：https://www.rfc-editor.org/rfc/rfc7540#section-8.1.2。
【讨论】：
谢谢，即使是冒号也无法正常工作，我正在研究它！【参考方案2】：此标头属于 HTTP/2。而且您不能将它们与 requests 库一起使用，但您可以使用另一个库 hyper
from hyper import HTTPConnection
conn = HTTPConnection('http2bin.org:443')
conn.request('GET', '/get')
resp = conn.get_response()
print(resp.read())
但是学习一个新库可能是一个耗时的过程，而且我们知道要求我们非常简单，要知道如何使用这个标头，link 已经很好地解释了它。
