Question

我有一个嵌入了已编译gzjs文件的静态html页面。使用过的预渲染，我的nginx文件是：

 server {
    listen 80;
    listen [::]:80;
    server_name www.example.com;
    expires $expires;

    root /usr/local/www/nginx-dist;

    index index.html index.htm;

    #proxy_set_header   Host $http_host;

    location / {
    try_files $uri @prerender;
}

    location @prerender {
proxy_set_header X-Prerender-Token MyToken;

set $prerender 0;
if ($http_user_agent ~* "googlebot|bingbot|googlebot-mobile|yandex|baiduspider|twitterbot|facebookexternalhit|rogerbot|linkedinbot|embedly|quora link preview|showyoubot|outbrain|pinterest|slackbot|vkShare|W3C_Validator") {
    set $prerender 1;
}
if ($args ~ "_escaped_fragment_") {
    set $prerender 1;
}
if ($http_user_agent ~ "Prerender") {
    set $prerender 0;
}
if ($uri ~* "\.(js|css|xml|less|png|jpg|jpeg|gif|pdf|doc|txt|ico|rss|zip|mp3|rar|exe|wmv|doc|avi|ppt|mpg|mpeg|tif|wav|mov|psd|ai|xls|mp4|m4a|swf|dat|dmg|iso|flv|m4v|torrent|ttf|woff|svg|eot)") {
    set $prerender 0;
}

#resolve using Google's DNS server to force DNS resolution and prevent caching of IPs
resolver 8.8.8.8;

if ($prerender = 1) {

    #setting prerender as a variable forces DNS resolution since nginx caches IPs and doesnt play well with load balancing
    set $prerender "service.prerender.io";
    rewrite .* /$scheme://$host$request_uri? break;
    proxy_pass http://$prerender;
}

if ($prerender = 0) {
        rewrite .* /index.html break;
    }
  }
}

仅获取301和

<html><head></head><body></body></html>

通过googlebot提取。

根据prerender.io，“您需要切换到服务器（如Unicorn或Puma），该服务器可以启动多个进程或使用非阻塞I / O，以便在Prerender尝试呈现时不会出现死锁。飞行中的页面”，有人可以建议如何针对我的情况吗？

谢谢。

Answer 1

如果使用的是nginx配置，则无需切换到Unicorn / Puma，因为它们是Rails服务器。

在官方支持的帮助下，我最终的nginx文件是：

 server {

listen [::]:80;
server_name www.YOURSITE.com;

root /usr/local/www/nginx-dist;

index index.html index.htm;

location / {
    if ($uri ~* "\.(php|jsp)") {
        return 404;
    }

    proxy_set_header X-Prerender-Token YOURTOKEN;

    set $prerender 0;
    if ($http_user_agent ~* "googlebot|Googlebot-Image|googlebot-mobile|Google-Structured-Data-Testing-Tool|AdsBot-Google-Mobile|Mediapartners-Google|bingbot|MSNBot|msnbot-media|AdsBot-Google-Mobile|yandex|baiduspider|Baiduspider-mobile|Baiduspider-image|Baiduspider-video|Baiduspider-news|Baiduspider-favo|Baiduspider-cpro|twitterbot|facebot|facebookexternalhit|rogerbot|linkedinbot|embedly|quora link preview|showyoubot|outbrain|pinterest|slackbot|tumblr|xml-sitemaps|vkShare|W3C_Validator|redditbot|Slack-ImgProxy|Slackbot-LinkExpanding|Site

    #if ($http_user_agent ~ "Prerender") {

   if ($prerender = 1) {

   try_files $uri $uri/ /index.html;
