nghttp 2客户端无法解析HTTP Upgrade响应标头

Question

我正在尝试使用nghttp服务器来测试HTTP/2.0。为了启动它，我使用：

nghttpd -v -d ~/Desktop/www 9000 --no-tls

在客户端，我键入：

nghttp -nvu http://127.0.0.1:9000

我在客户端中有这个输出

[  0.000] Connected
[  0.000] HTTP Upgrade request
GET / HTTP/1.1
host: 127.0.0.1:9000
connection: Upgrade, HTTP2-Settings
upgrade: h2c
http2-settings: AAMAAABkAAQAAP__
accept: */*
user-agent: nghttp2/1.35.1
[ERROR] Failed to parse HTTP Upgrade response header: 
(HPE_INVALID_CONSTANT) invalid constant string
Some requests were not processed. total=1, processed=0

在服务器终端中

IPv6: listen :::9000
IPv4: listen 0.0.0.0:9000
[id=1] [  5.803] send SETTINGS frame <length=6, flags=0x00, stream_id=0>
(niv=1)
[SETTINGS_MAX_CONCURRENT_STREAMS(0x03):100]
[id=1] [  5.803] closed

我该如何解决这个问题？

Answer 1

nghttpd不支持升级。请参阅作者的文章。客户端nghttp没有问题。

您可以使用nghttpx、反向代理和它背后的http2服务器。

$ nghttp -nvu http://nghttp2.org/

Answer 2

根据上面的答案。我做这个

http2服务器

nghttpd -v -d /Desktop/www --no-tls -a 127.0.0.1 9000

反向代理

nghttpx -b '127.0.0.1,9000;;proto=h2' -f '127.0.0.1,9001;no-tls' -L INFO -o

http2客户端

nghttp -v http://127.0.0.1:9001/index.html
