使用 HTTP/2 设置 Quart 服务器

Question

我正在尝试设置一个 Quart 服务器来与 HTTP/2 一起玩。我一直在尝试通过以下位置的最少文档：

https://gitlab.com/pgjones/quart

我有：

$ cat app.py
from quart import Quart, render_template, websocket

app = Quart(__name__)

@app.route("/")
async def hello():
    return await render_template("index.html")

@app.route("/api")
async def json():
    return {"hello": "world"}

@app.websocket("/ws")
async def ws():
    while True:
        await websocket.send("hello")
        await websocket.send_json({"hello": "world"})

if __name__ == "__main__":
    app.run(host="0.0.0.0", port=5001)

一些基本检查：

$ curl -I --http2 http://acme.corp:5001
HTTP/1.1 101
date: Tue, 02 Mar 2021 10:05:12 GMT
server: hypercorn-h11
connection: upgrade
upgrade: h2c

HTTP/2 200
content-type: text/html; charset=utf-8
content-length: 0
date: Tue, 02 Mar 2021 10:05:12 GMT
server: hypercorn-h2

查看输出

$ python3 app.py
 * Serving Quart app 'app'
 * Environment: production
 * Please use an ASGI server (e.g. Hypercorn) directly in production
 * Debug mode: False
 * Running on http://0.0.0.0:5001 (CTRL + C to quit)
[2021-03-02 11:01:49,083] Running on http://0.0.0.0:5001 (CTRL + C to quit)
[2021-03-02 11:01:53,011] 10.221.0.114:53637 GET / 1.1 200 0 5817
[2021-03-02 11:01:53,255] 10.221.0.114:53637 GET /favicon.ico 1.1 404 103 1348

这是我从 chrome 加载 index.html 页面时看到的：

我缺少什么才能从 chrome 得到 http/2？

Answer 1

您在本地将不安全的 HTTP 1.1 请求升级为 不安全 HTTP 2 请求。这适用于 Quart 和 curl，但包括 chrome 在内的浏览器执行 not support insecure (unencrypted) HTTP/2. For it to work in chrome I create a self signed certificate, passing the certfile and keyfile options to the run and accept the warning chrome offers when visiting the site. An example exists here.
