Question

对于VAADIN Java应用程序，当我进入设计的网页时，我创建了一个加载的类。

这个课必须每天凌晨12:00开始，所以我想创建一个bash脚本，它使用curl来请求设计的页面来加载课程并启动所有内容。

他们的问题是，当我尝试使用

获取curl页面时

curl http://localhost:8080/Cub2dV725/mailengine

我明白了：

<!DOCTYPE html>

 <head>
  <meta http-equiv="Content-Type" content="text/html; charset=utf-8">

 <body scroll="auto" class=" v-generated-body">

   <div class=" v-app-loading"></div>

  </div>
  <iframe tabindex="-1" id="__gwt_historyFrame" style="position:absolute;width:0;height:0;border:0;overflow:hidden" src="javascript:false"></iframe>
  <script type="text/javascript" src="./VAADIN/vaadinBootstrap.js"></script>
  <script type="text/javascript">//<![CDATA[
if (!window.vaadin) alert("Failed to load the bootstrap javascript: .\/VAADIN\/vaadinBootstrap.js");
if (typeof window.__gwtStatsEvent != 'function') {
vaadin.gwtStatsEvents = [];
window.__gwtStatsEvent = function(event) {vaadin.gwtStatsEvents.push(event); return true;};
}
vaadin.initApplication("Cub2DV725marketingmailengine-730874983",{
    "heartbeatInterval": 300,
    "versionInfo": {
        "vaadinVersion": "7.2.5"
    },
    "vaadinDir": ".\/VAADIN\/",
    "authErrMsg": {
        "message": "Take note of any unsaved data, and <u>click here<\/u> or press ESC to continue.",
        "caption": "Authentication problem"
    },
    "widgetset": "com.vaadin.DefaultWidgetSet",
    "theme": "reindeer",
    "debug": true,
    "comErrMsg": {
        "message": "Take note of any unsaved data, and <u>click here<\/u> or press ESC to continue.",
        "caption": "Communication problem"
    },
    "standalone": true,
    "sessExpMsg": {
        "message": "Take note of any unsaved data, and <u>click here<\/u> or press ESC key to continue.",
        "caption": "Session Expired"
    }
});
//]]></script>
 </body>
</html>

该类尚未加载（我知道因为有一个system.out.print（＆＃34;已加载＆＃34;）;在课程开始时。

我使用PhantomJS

找到了解决方案

刚刚用这段代码创建了一个script.js：

var page = require('webpage').create();
page.open('http://localhost:8080/Cub2DV725/mailengine', function() {
        phantom.exit();
});

和bash脚本：

这里，/ var / lib / PhantomJs是我提取它的地方

/var/lib/PhantomJs/bin/phantomjs /var/scripts/script.js

现在我只需要添加一个crontab条目来每天凌晨12:00启动脚本
