你好，亲爱的 SO 社区。

我有一个问题折磨了我好几个月没有解决办法。

我试图在使用一些以冒号开头的标头的 HTTP/2 端点发出请求。例子：

:method: "POST"

我尝试过 python(hyper, requests), php(guzzle) 和 js(fetch)。据推测，我已经使用 js 实现了所需的结果，但是 CORS 策略返回了一个“不透明”的结果。

任何帮助都会很棒！

JS 结果大概是正确的“不透明”

fetch("https://www.example.com/users/sign_in", 
        {
          "credentials":"include",
          "headers":{
            "accept":"text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,image/apng,*/*;q=0.8,application/signed-exchange;v=b3",
            "accept-language":"en-US,en;q=0.9,el;q=0.8",
            "cache-control":"max-age=0",
            "content-type":"application/x-www-form-urlencoded",
            "accept-encoding": "gzip, deflate, br",
            "content-length": 614,
            "origin": "https://www.example.com",
            "sec-fetch-mode": "navigate",
            "sec-fetch-site": "same-origin",
            "user-agent": "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/76.0.3809.87 Safari/537.36",
          },
          "referrer":"https://www.example.com/users/sign_in",
          "referrerPolicy":"no-referrer-when-downgrade",
          "redirect": "follow",
          "body":"..."
          "method":"POST",
          "mode":"no-cors",
          ":authority": "www.example.com",
          ":method": "POST",
          ":path": "/users/sign_in",
          ":scheme": "https"
        })

Python 结果 500 或 404

 context = tls.init_context() …
