问题:Safari 使用 HTTP/2 时没有响应

我是 nginx 的新手(过去一直使用 apache)。

目前我正在尝试设置一个位于 apache 后端前面的缓存,最终我认为(基于我迄今为止对 nginx 的良好经验)我们将切换到只使用 nginx。

一旦我打开 http2 Safari 就无法得到响应。在错误日志中没有任何迹象表明存在问题,如果我打开访问日志并检查那里,我可以看到 Safari 客户端进行了很多很多连接,就像它只是不断刷新页面一样。

我已经尝试了许多 nginx 版本,因为我注意到最新的稳定版本可能存在问题。所以我尝试降级到 1.9.14 以及升级到 1.11.1,都没有运气。

Nginx 只编译:

./configure --with-http_ssl_module --with-http_v2_module

Nginx -V 输出:

nginx version: nginx/1.11.1
built by gcc 5.3.1 20160413 (Ubuntu 5.3.1-14ubuntu2.1) 
built with OpenSSL 1.0.2g-fips  1 Mar 2016
TLS SNI support enabled
configure arguments: --with-http_ssl_module --with-http_v2_module

我的配置看起来像这样(我的站点可用配置):

upstream backend {
    server 127.0.0.1:8088 weight=100;
}

server {
    listen 443 ssl http2 deferred;
    server_name www.server.name;

    ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
    ssl_ciphers "ECDHE-ECDSA-AES128-GCM-SHA256:ECDHE-RSA-AES128-GCM-SHA256:ECDHE-RSA-AES256-GCM-SHA384:ECDHE-ECDSA-AES256-GCM-SHA384:DHE-RSA-AES128-GCM-SHA256:DHE-DSS-AES128-GCM-SHA256:kEDH+AESGCM:ECDHE-RSA-AES128-SHA256:ECDHE-ECDSA-AES128-SHA256:ECDHE-RSA-AES128-SHA:ECDHE-ECDSA-AES128-SHA:ECDHE-RSA-AES256-SHA384:ECDHE-ECDSA-AES256-SHA384:ECDHE-RSA-AES256-SHA:ECDHE-ECDSA-AES256-SHA:DHE-RSA-AES128-SHA256:DHE-RSA-AES128-SHA:DHE-DSS-AES128-SHA256:DHE-RSA-AES256-SHA256:DHE-DSS-AES256-SHA:DHE-RSA-AES256-SHA:!aNULL:!eNULL:!EXPORT:!DES:!RC4:!3DES:!MD5:!PSK";
    ssl_prefer_server_ciphers on;

    ssl_certificate /path/to/cert.crt
    ssl_certificate_key /path/to/cert_key.key

    ssl_session_cache shared:SSL:10m;
    ssl_session_timeout 10m;

    add_header Strict-Transport-Security "max-age=31536000; includeSubdomains;";

    location / {
            proxy_redirect off;
            proxy_set_header Host $host;
            proxy_set_header X-Real-IP $remote_addr;
            proxy_set_header X-Forwarded_For $proxy_add_x_forwarded_for;

            proxy_pass https://backend;
    }

}

如果我从listen参数中删除http2并重新启动它就可以正常工作......

我一直在寻找我是否在我的配置中做错了什么,但我找不到任何东西......但是,如果我的配置有一些改进,请告诉我。然而,主要问题是,每当我使用 Safari 访问 URL(缓存或不缓存)时,它都会一直加载。

这是请求后我的访问日志的样子:

谢谢!

好吧!经过大量研究和测试,结果发现我需要在我的配置中隐藏 Upgrade 标头。proxy_hide_header Upgrade;
