javax.script.ScriptException : sun. org.mozilla.javascript.internal.EcmaError:ReferenceError: "document"未定义

Question

我运行下面的 java 文件时遇到此错误。

 import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.net.URL;
import java.net.URLConnection;
import java.util.List;

import javax.script.Bindings;
import javax.script.Invocable;
import javax.script.ScriptContext;
import javax.script.ScriptEngine;
import javax.script.ScriptEngineManager;
import javax.script.ScriptException;

public class TestForTheThread {
    public static void main(String args[]) {
        ScriptEngineManager mgr = new ScriptEngineManager();
        ScriptEngine engine = mgr.getEngineByName("javascript");
        try {
             URL yahoo = new URL("http://localhost/XMLLoadProject/thiru.js");  
                URLConnection yc = yahoo.openConnection();  
                BufferedReader in = new BufferedReader(new InputStreamReader(yc.getInputStream()));
                engine.eval(in);
        } catch (ScriptException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
            System.out.println("fail to load");
        }catch (Exception e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
            System.out.println("fail to load");
        }
        Invocable invocable = (Invocable) engine;
        Object result;
        try {
            result = invocable.invokeFunction("idplogurl", "thriu");
            System.out.println(result);
        } catch (ScriptException e) {
            e.printStackTrace();
        } catch (NoSuchMethodException e) {
            e.printStackTrace();
        }
    }
}

示例 js 文件

var idplogurl = function(idpcode) {
    /*! jQuery v1.11.2 | (c) 2005, 2014 jQuery Foundation, Inc. | jquery.org/license */
   document.write('<script type="text/javascript" src="'+ idpcode+ '"></script>');
}

在 javascript 文件('thiru.js')中包含该文档(javascript 默认对象)。有些网站说没有浏览器就不可能。请任何人针对此错误提出质疑。我收到此错误

javax.script.ScriptException:sun.org.mozilla.javascript.internal.EcmaError:ReferenceError:“文档”未定义。 (#17) 在第 17 行

请帮助我......

尝试使用这个或驼色外壳

ScriptEngine engine = mgr.getEngineByName("JavaScript");
 or
ScriptEngine engine = mgr.getEngineByName("javaScript");

粘贴您的 JavaScript 代码

尝试this你可能会得到一些想法。
