我根据 Digital Ocean 论文设置了我的 Nginx conf ，现在 http2 可用...

但是在 Chrome（版本 54.0.2840.98（64 位））开发工具中，它总是在 HTTP 1/1 上：

NAME             METHOD  STATUS  PROTOCOL
shell.js?v=xx..    GET    200     http/1.1

我的服务器正在运行 Ubuntu 16.04 LTS，它同时支持 ALPN 和 NPN ，并且随附的 openssl 版本是 1.0.2g

我用这个工具站点检查了 http2 支持，结果是： 

Yeah! example.com supports HTTP/2.0. ALPN supported...

也可以用 curl 检查

 $ curl -I --http2 https://www.example.com
  HTTP/2 200 
  server: nginx/1.10.0 (Ubuntu)
  date: Tue, 13 Dec 2016 15:59:13 GMT
  content-type: text/html; charset=utf-8
  content-length: 5603
  x-powered-by: Express
  cache-control: public, max-age=0
  etag: W/"15e3-EUyjnNnyevoQO+tRlVVZxg"
  vary: Accept-Encoding
  strict-transport-security: max-age=63072000; includeSubdomains
  x-frame-options: DENY
  x-content-type-options: nosniff

我还从控制台检查了 is-http2 cli

is-http2 www.amazon.com
× HTTP/2 not supported by www.amazon.com
Supported protocols: http/1.1

is-http2 www.example.com
✓ HTTP/2  supported by www.example.com
Supported protocols: h2 http/1.1

用我的本地主机上的 openssl 测试

$ echo | openssl s_client -alpn h2 -connect www.example.com:443 | grep ALPN
 depth=2 O = Digital Signature Trust Co., CN = DST Root CA X3
 verify return:1
 depth=1 C = US, O = Let's Encrypt, CN = Let's Encrypt Authority X3
 verify return:1
 depth=0 CN = example.com
 verify return:1
 ALPN protocol: h2
 DONE

为什么 Chrome 被抛在了后面？我如何也可以使用 Safari (v 10.0.1) 检查它

nginx google-chrome http2
