Question

我尝试使用带有Meteor 1.5 App的prerender.io。我使用npm prerender-node包

  var prerenderio = Npm.require('prerender-node') .set('prerenderToken', token)
                                                .set('protocol', protocol)
                                                .set('host', host);  


  // Feed it to middleware! (app.use)
  WebApp.connectHandlers.use(prerenderio);

我使用代码200登录prerender.io.Paged被缓存但页面只包含头部和空体。

为了进行测试，我添加了包meteorhacks：注入初始和插入的线在身体，它工作正常。我想知道我的路由器是否有问题是流路由器。

我也放置

<head>
  <meta charset="utf-8">
  <meta name="fragment" content="!">
  ALL  <meta ... >
  <!-- a script -->
  <scripts ... >
  <!-- prerenderio -->
  <script> console.log(Date()); window.prerenderReady = false; </script>  
</head>

为了测试，我刷新了prerender.io的缓存。当我测试https://www.toto.com?_escaped_fragment_=

时

我在客户端控制台中没有任何时间。我在prerender.io上看到了新的一行

我做了同样的测试 https://www.bing.com/webmaster/diagnostics/seo/analyzer

现在让我们看一下新的缓存行内容：

在这里，我给出了整个身体内容。我没有删除任何行。

在这里预先渲染用户。我们遇到了Prerender的问题，没有等到所有脚本都运行完成，因此计算的dom还没有完全呈现，这听起来就像你遇到的那样。为方便起见，我们使用prerender文档中描述的prerender ready标志解决了这个问题：

将它放在HTML中：

<script> window.prerenderReady = false; </script>

当我们看到window.prerenderReady设置为false时，我们将等到设置为true以保存HTML。当您的页面准备就绪时（通常在ajax调用之后）执行以下命令。

window.prerenderReady = true;

空身使用Prerender.io与流星
