預渲染與本地測試服務器

我想在我的本地開發服務器上使用Prerender進行測試。 Flask（網站後端）的應用程序服務器在localhost：5000上運行，現在我已經在localhost：3000上設置了Prerender服務器。論預渲染GitHub的頁面，它說，爲了使用預渲染爲本地服務，我需要預渲染與本地測試服務器

export PRERENDER_SERVICE_URL=<your local url>

，也爲我的nginx的配置文件

server { 
    listen 80; 
    server_name example.com; 

    root /path/to/your/root; 
    index index.html; 

    location/{ 
     try_files $uri @prerender; 
    } 

    location @prerender { 
     #proxy_set_header X-Prerender-Token YOUR_TOKEN; 

     set $prerender 0; 
     if ($http_user_agent ~* "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)") { 
      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; 
     } 
    } 
}

我有兩個問題：

1.什麼呢

export PRERENDER_SERVICE_URL=<your local url>

嗎？我應該如何設置「您的本地網址」？它應該是網站的應用程序服務器（它是localhost：5000）的url還是它應該是Prerender服務器（它是localhost：3000）的url。

2.我改變我的nginx.conf包括：

server { 
    listen 80; 
    server_name localhost:5000; 

    root /path/to/my/root; 
    index index.html; 

    location/{ 
     try_files $uri @prerender; 
    } 

    location @prerender { 
     #proxy_set_header X-Prerender-Token YOUR_TOKEN; 

     set $prerender 0; 
     if ($http_user_agent ~* "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)") { 
      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 $prerender "localhost:3000"; 
      rewrite .* /$scheme://$host$request_uri? break; 
      proxy_pass http://$prerender; 
     } 
     if ($prerender = 0) { 
      rewrite .* /index.html break; 
     } 
    } 
}

，它似乎並沒有工作。當我訪問本地主機（localhost：80）時，它說404沒有找到。似乎它甚至沒有正確地將流量路由到localhost：5000。

任何想法，我做了什麼錯？非常感謝！

由於您使用的是nginx配置，因此不需要使用PRERENDER_SERVICE_URL。它不會爲你的情況做任何事情。

將service.prerender.io更改爲localhost:3000就像您在nginx配置中所做的一樣，是指向您本地Prerender服務器的正確方法。

雖然，你只是沒有正確設置nginx。您可能必須將重寫更改爲index.html，並將其更改爲localhost：5000的proxy_pass。這應該得到localhost:80工作，然後您將訪問localhost:80/?_escaped_fragment_=

的預渲染頁面
