好奇怪，http2, 静态资源都不走 http2

Question

下面是nginx -V的代码

nginx version: nginx/1.12.1
built by gcc 4.8.4 (Ubuntu 4.8.4-2ubuntu1~14.04.3)
built with OpenSSL 1.0.2j  26 Sep 2016
TLS SNI support enabled
configure arguments: --prefix=/etc/nginx --sbin-path=/usr/sbin/nginx --modules-path=/usr/lib/nginx/modules --conf-path=/etc/nginx/nginx.conf --error-log-path=/var/log/nginx/error.log --http-log-path=/var/log/nginx/access.log --pid-path=/var/run/nginx.pid --lock-path=/var/run/nginx.lock --http-client-body-temp-path=/var/cache/nginx/client_temp --http-proxy-temp-path=/var/cache/nginx/proxy_temp --http-fastcgi-temp-path=/var/cache/nginx/fastcgi_temp --http-uwsgi-temp-path=/var/cache/nginx/uwsgi_temp --http-scgi-temp-path=/var/cache/nginx/scgi_temp --with-openssl=/home/naice_manager/openssl-1.0.2j --with-file-aio --with-threads --with-http_addition_module --with-http_auth_request_module --with-http_dav_module --with-http_flv_module --with-http_gunzip_module --with-http_gzip_static_module --with-http_mp4_module --with-http_random_index_module --with-http_realip_module --with-http_secure_link_module --with-http_slice_module --with-http_ssl_module --with-http_stub_status_module --with-http_sub_module --with-http_v2_module

配置好 nginx.conf之后

..... // 省略ssl 证书配置
location / {
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header X-Forward-For $proxy_add_x_forwarded_for;
    proxy_set_header Host $http_host;
    proxy_set_header X-Nginx-Proxy true;

    proxy_pass http://blog;
    proxy_redirect off;
  }
  location ~* ^.+\.(jpg|jpeg|gif|png|ico|css|js|pdf|txt){
    root /www/blog/production/current/dist;
  }

只有 html 和接口的服务走http2，静态文件都都是走 http/1的，有点蛋疼呀？？
求大神指导,是不是location的原因呀

Answer 1

因为是http请求,就会走http1.1

现在支持http/2的,基本上都是基于https这种加密的请求

要想使用明文的http请求,需要指定upgrage 字段和collection字段.
