Question

我有使用phantomjs

创建的脚本文件

var webPage = require('webpage');
var page = webPage.create();

page.open(URL, function (status) {
    var content = page.content;
    console.log('Content: ' + content);
    phantom.exit();
});

现在我想在Java程序中使用这个脚本，但我不能。我在我的项目中这样做

ScriptEngineManager s = new ScriptEngineManager();
ScriptEngine se = s.getEngineByName("JavaScript");
se.eval(new FileReader("myScript.js"));

但是`这是结果

我该怎么办？

编辑：我把这一行放在我的代码中：

Process process = Runtime.getRuntime().exec("/usr/bin/phantomjs myScript.js");

但这不起作用。 progrma返回与以前相同的错误。我该怎么办？

Answer 1

要求不是标准javascript的一部分，而是NodeJS的一项功能。你的JAVA程序不知道如何处理它。

另见这个问题及其接受的答案：

What is this Javascript "require"?

Answer 2

脚本引擎无法访问PhantomJS / nodejs添加到JavaScript的对象（require)

您可以使用exec执行幻像。像

这样的东西

 // You need the correct path for phantomJs
 Process process = Runtime.getRuntime().exec("/usr/bin/phantomjs myScript.js");
