Angularjs Prerender未使用Nginx检测到令牌

我们有一个angular应用程序，我们正试图实现SEO目的

我们使用站点地图缓存了所有url，并遵循官方的Nginx教程：

但是prerender.io会继续显示以下消息： 我们还没有看到带有预渲染令牌的请求。

您可以在此处查看我们的Nginx代码：

server {
  listen 443;
  server_name example.com;
  access_log /var/log/nginx/example.com.ssl.access.log;
  error_log /var/log/nginx/example.com.ssl.error.log debug;

  #SSL conf

  location / {

    try_files $uri @prerender;

    if ($request_filename ~* ^.*?/([^/]*?)$)
    {
        set $filename $1;
    }

    if ($filename ~* ^.*?\.(eot)|(ttf)|(woff)$){
        add_header Access-Control-Allow-Origin *;
    }

    proxy_redirect off;
    proxy_set_header   X-Real-IP            $remote_addr;
    proxy_set_header   X-Forwarded-For  $proxy_add_x_forwarded_for;
    proxy_set_header   X-Forwarded-Proto $scheme;
    proxy_set_header   Host                   $http_host;
    proxy_set_header   X-NginX-Proxy    true;
    proxy_set_header   Connection "";
    proxy_http_version 1.1;
    proxy_cache one;
    proxy_cache_key sfs$request_uri$scheme;

    proxy_pass http://example.com;
  }

  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|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;
      }
  }

我们尝试了类似问题的不同解决方案，但没有任何效果

我想知道try\u文件是否因为某种原因在这里不起作用。可以尝试将预渲染配置内联吗

server {
  listen 443;
  server_name example.com;
  access_log /var/log/nginx/example.com.ssl.access.log;
  error_log /var/log/nginx/example.com.ssl.error.log debug;

  #SSL conf

  location / {

    if ($request_filename ~* ^.*?/([^/]*?)$)
    {
        set $filename $1;
    }

    if ($filename ~* ^.*?\.(eot)|(ttf)|(woff)$){
        add_header Access-Control-Allow-Origin *;
    }

    #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|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;
    }

    proxy_redirect off;
    proxy_set_header   X-Real-IP            $remote_addr;
    proxy_set_header   X-Forwarded-For  $proxy_add_x_forwarded_for;
    proxy_set_header   X-Forwarded-Proto $scheme;
    proxy_set_header   Host                   $http_host;
    proxy_set_header   X-NginX-Proxy    true;
    proxy_set_header   Connection "";
    proxy_http_version 1.1;
    proxy_cache one;
    proxy_cache_key sfs$request_uri$scheme;

    proxy_pass http://example.com;
  }

}

昨天我回答这个问题时可能没有注意到这一点，但您的令牌也被注释掉了：#proxy_set_header X-Prerender-token your_token；请确保从该行中删除#谢谢您的回答，但这是一个复制粘贴错误：）我们没有对令牌进行评论，对此表示抱歉。谢谢您的回答，但这似乎也不起作用：（它一直显示此消息：我们还没有看到带有Prerender令牌的请求。修复了！我们在$http\u user\u代理中添加了“Googlebot”，如果：）你不想通过他们的用户代理检查Google机器人，因为这可能会让你因为伪装而受到惩罚。如果你在页面的最后一页添加了“转义”标记，那么Google、Bing和其他爬虫将对？\u转义\u片段=URL进行爬网。谢谢你提供的信息！我们将meta标记放在上，当我们将？\u转义\u片段放在URL上时，它将正常收费。但是我们用谷歌网站管理员工具蚀刻网页，但没有显示呈现的html…似乎谷歌没有抓取？\u转义\u片段=URLFetch，因为谷歌有一个已知的错误，他们不会自动检查标签，所以使用“作为谷歌抓取”时，你想手动输入？\u转义\u片段=URLFetch。真正的谷歌机器人会看到该片段meta标记并自行重新请求？\u转义\u片段=URL。
