我有一个单页应用程序，服务器端在 node.JS 上。AngularJS 资源托管在 S3 Bucket 上。我有一个 nginx 服务器层，它代理基于节点的 api 和来自 S3 Bucket 的静态内容。我想预渲染 AngularJS 应用程序以将静态内容提供给搜索引擎。我已将 nginx.conf 更改为使用prerender.io，但 AngularJS 应用程序未完全加载。当我尝试使用“_escaped_fragment_=”手动测试预渲染片段时，“nv-view”中的任何内容都没有加载。以下是 nginx.conf 片段：

server {
    listen 80;
    server_name example.com;
    access_log /var/log/nginx/dev.log main;

    location /api/ {
        rewrite /api/(.*) /$1  break;
        proxy_pass         http://127.0.0.1:8080/;
        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_set_header   X-NginX-Proxy    true;
        proxy_connect_timeout      90;
        proxy_send_timeout         90;
        proxy_read_timeout         90;
        proxy_buffer_size          4k;
        proxy_buffers              4 32k;
        proxy_busy_buffers_size    64k;
        proxy_temp_file_write_size 64k;

        # websockets:
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";

        client_max_body_size       30m;
        client_body_buffer_size    128k;
    }

    location / {
        try_files $uri @prerender;
    }

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

        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://XXX.s3-website-us-east-1.amazonaws.com$request_uri? break;
            proxy_pass http://$prerender;
        }
        if ($prerender = 0) {
            proxy_pass $scheme://XXX.s3-website-us-east-1.amazonaws.com;
        }
    }
}

PhantomJS 可能会出错。您是否尝试在本地运行 Prerender 服务器？将您正在测试的 URL 发送给我，我很乐意对其进行测试，看看有什么问题！todd@prerender.io
