小编Cri*_*ine的帖子

我正在尝试在Javascript Web Worker中加载Google Maps API,但无法加载地图库.Web Worker代码如下所示:

importScripts('http://maps.googleapis.com/maps/api/js?libraries=geometry&key=MYAPIKEY&sensor=FALSE'); 

这很简单

Script Error.

在我尝试加载工作者时在Chrome中.

我假设地图库中的某些东西试图访问DOM.但这只是猜测.有没有人有解决方案？

编辑: 我打开上面的链接,并试图提取+修改它的内容.所以WebWorker.js现在看起来像这样:

var window = {google: {}};
var google = {maps: {}};
(function() {

  function getScript(src) {
      importScripts(src);
    //document.write('<' + 'script src="' + src + '"><' + '/script>');
  }

  var modules = google.maps.modules = {};
  google.maps.__gjsload__ = function(name, text) {
    modules[name] = text;
  };

  google.maps.Load = function(apiLoad) {
    delete google.maps.Load;
    apiLoad([0.009999999776482582,[[["http://mt0.googleapis.com/vt?lyrs=m@306000000\u0026src=api\u0026hl=de-DE\u0026","http://mt1.googleapis.com/vt?lyrs=m@306000000\u0026src=api\u0026hl=de-DE\u0026"],null,null,null,null,"m@306000000",["https://mts0.google.com/vt?lyrs=m@306000000\u0026src=api\u0026hl=de-DE\u0026","https://mts1.google.com/vt?lyrs=m@306000000\u0026src=api\u0026hl=de-DE\u0026"]],[["http://khm0.googleapis.com/kh?v=174\u0026hl=de-DE\u0026","http://khm1.googleapis.com/kh?v=174\u0026hl=de-DE\u0026"],null,null,null,1,"174",["https://khms0.google.com/kh?v=174\u0026hl=de-DE\u0026","https://khms1.google.com/kh?v=174\u0026hl=de-DE\u0026"]],[["http://mt0.googleapis.com/vt?lyrs=h@306000000\u0026src=api\u0026hl=de-DE\u0026","http://mt1.googleapis.com/vt?lyrs=h@306000000\u0026src=api\u0026hl=de-DE\u0026"],null,null,null,null,"h@306000000",["https://mts0.google.com/vt?lyrs=h@306000000\u0026src=api\u0026hl=de-DE\u0026","https://mts1.google.com/vt?lyrs=h@306000000\u0026src=api\u0026hl=de-DE\u0026"]],[["http://mt0.googleapis.com/vt?lyrs=t@132,r@306000000\u0026src=api\u0026hl=de-DE\u0026","http://mt1.googleapis.com/vt?lyrs=t@132,r@306000000\u0026src=api\u0026hl=de-DE\u0026"],null,null,null,null,"t@132,r@306000000",["https://mts0.google.com/vt?lyrs=t@132,r@306000000\u0026src=api\u0026hl=de-DE\u0026","https://mts1.google.com/vt?lyrs=t@132,r@306000000\u0026src=api\u0026hl=de-DE\u0026"]],null,null,[["http://cbk0.googleapis.com/cbk?","http://cbk1.googleapis.com/cbk?"]],[["http://khm0.googleapis.com/kh?v=86\u0026hl=de-DE\u0026","http://khm1.googleapis.com/kh?v=86\u0026hl=de-DE\u0026"],null,null,null,null,"86",["https://khms0.google.com/kh?v=86\u0026hl=de-DE\u0026","https://khms1.google.com/kh?v=86\u0026hl=de-DE\u0026"]],[["http://mt0.googleapis.com/mapslt?hl=de-DE\u0026","http://mt1.googleapis.com/mapslt?hl=de-DE\u0026"]],[["http://mt0.googleapis.com/mapslt/ft?hl=de-DE\u0026","http://mt1.googleapis.com/mapslt/ft?hl=de-DE\u0026"]],[["http://mt0.googleapis.com/vt?hl=de-DE\u0026","http://mt1.googleapis.com/vt?hl=de-DE\u0026"]],[["http://mt0.googleapis.com/mapslt/loom?hl=de-DE\u0026","http://mt1.googleapis.com/mapslt/loom?hl=de-DE\u0026"]],[["https://mts0.googleapis.com/mapslt?hl=de-DE\u0026","https://mts1.googleapis.com/mapslt?hl=de-DE\u0026"]],[["https://mts0.googleapis.com/mapslt/ft?hl=de-DE\u0026","https://mts1.googleapis.com/mapslt/ft?hl=de-DE\u0026"]],[["https://mts0.googleapis.com/mapslt/loom?hl=de-DE\u0026","https://mts1.googleapis.com/mapslt/loom?hl=de-DE\u0026"]]],["de-DE","US",null,0,null,null,"http://maps.gstatic.com/mapfiles/","http://csi.gstatic.com","https://maps.googleapis.com","http://maps.googleapis.com",null,"https://maps.google.com","https://gg.google.com","http://maps.gstatic.com/maps-api-v3/api/images/","https://www.google.com/maps",0],["http://maps.gstatic.com/maps-api-v3/api/js/21/3/intl/de_ALL","3.21.3"],[141790386],1,null,null,null,null,null,"",["geometry"],null,0,"http://khm.googleapis.com/mz?v=174\u0026","AIzaSyDQi59vEjsIzBM-AFMeDbszVsOckQOb5A8","https://earthbuilder.googleapis.com","https://earthbuilder.googleapis.com",null,"http://mt.googleapis.com/vt/icon",[["http://mt0.googleapis.com/vt","http://mt1.googleapis.com/vt"],["https://mts0.googleapis.com/vt","https://mts1.googleapis.com/vt"],null,null,null,null,null,null,null,null,null,null,["https://mts0.google.com/vt","https://mts1.google.com/vt"],"/maps/vt",306000000,132],2,500,[null,"http://g0.gstatic.com/landmark/tour","http://g0.gstatic.com/landmark/config",null,"http://www.google.com/maps/preview/log204","","http://static.panoramio.com.storage.googleapis.com/photos/",["http://geo0.ggpht.com/cbk","http://geo1.ggpht.com/cbk","http://geo2.ggpht.com/cbk","http://geo3.ggpht.com/cbk"]],["https://www.google.com/maps/api/js/master?pb=!1m2!1u21!2s3!2sde-DE!3sUS!4s21/3/intl/de_ALL","https://www.google.com/maps/api/js/widget?pb=!1m2!1u21!2s3!2sde-DE"],null,0,0,"/maps/api/js/ApplicationService.GetEntityDetails",0], loadScriptTime);

    );

})();

但这仍然会导致"脚本错误".

我正在尝试模糊我的JavaFX应用程序,但它失败了.生成的结果不起作用,我不明白为什么.生成的jar只是失败,因为fxml文件不能再加载所有导入(ClassNotFoundException).

部署工作流程:

1. 构建可运行的jar(在IntelliJ knwon中作为工件)
2. 使用ProGuard对jar进行模糊处理
3. 修复ProGuard无法完成的jar中的一些问题

1)最小的示例应用程序

示例应用程序'GuardTest'是一个IntelliJ项目,由3个类组成.

• sample.Main:包含应用程序入口点并加载GUI fxml文件'sample.fxml'
• sample.Controller:'sample.fxml'的控制器类
• controls.CustomControl:一个从HBox继承的简单javafx控件.这在'sample.fxml'中使用

'sample.fxml'的内容:

<?import javafx.scene.control.Button?>
<?import javafx.scene.layout.VBox?>

<?import controls.CustomControl?>

<VBox fx:controller="sample.Controller"
          xmlns:fx="http://javafx.com/fxml">
    <children>
        <CustomControl>
            <children>
                <Button text="Test"></Button>
            </children>
        </CustomControl>
    </children>
</VBox>

2)混淆

现在我使用ProGuard生成从上面的项目生成的jar文件.我使用以下设置:

-target 8

-injars ./out/artifacts/JavaFXApp/JavaFXApp.jar

-outjars ./out/obfuscated/Obfuscated.jar
-ignorewarnings

-printmapping ./out/obfuscated/proguard.map
-dontusemixedcaseclassnames
-dontshrink
-dontoptimize
-dontskipnonpubliclibraryclasses
-dontskipnonpubliclibraryclassmembers

#-flattenpackagehierarchy
-repackageclasses 'p'
-allowaccessmodification

-libraryjars "<java.home>/lib/rt.jar"
-libraryjars "<java.home>/lib/javaws.jar"
-libraryjars "<java.home>/lib/ext/jfxrt.jar"

-adaptresourcefilecontents **.fxml,**.properties,META-INF/MANIFEST.MF,images/*.jar,publicCerts.store,production.version

-keepattributes javafx.fxml.FXML,Exceptions,InnerClasses,Signature,Deprecated,SourceFile,LineNumberTable,LocalVariable*Table,*Annotation*,Synthetic,EnclosingMethod
-keepclassmembers class * {
    @javafx.fxml.FXML *;
}

-keepclassmembernames public class com.javafx.main.Main, com.nywelt.sharkload.application.Main {
    public static void main(java.lang.String[]);
}
-keepclasseswithmembers …

JavaFX是否与Java SwingWorker类等效？

我知道JavaFX 任务,但是你只能发布字符串消息或进度.我只想在GUI线程中调用一个方法,就像我对SwingWorker一样(通过发布任意类型的消息).

赫雷斯是我的意思的一个例子:

class PrimeNumbersTask extends
         SwingWorker<List<Integer>, Integer> {
     PrimeNumbersTask(JTextArea textArea, int numbersToFind) {
         //initialize
     }

      @Override
     public List<Integer> doInBackground() {
         while (! enough && ! isCancelled()) {
                 number = nextPrimeNumber();
                 publish(number);
                 setProgress(100 * numbers.size() / numbersToFind);
             }
         }
         return numbers;
     }

      @Override
     protected void process(List<Integer> chunks) {
         for (int number : chunks) {
             textArea.append(number + "\n"); // HERE: execute in GUI thread
         }
     }
 }

解

非常感谢您的回答.我正在寻找的解决方案是使用Platform.runLater(Runnable guiUpdater).

我想从模块内向 Typescript (1.8) 中的数组原型添加一个函数。

我正在更改 utils.ts 文件中的原型：

declare global {
    interface Array<T> {
        remove(obj: any): void;
    }
}

Array.prototype.remove = function(obj) {
    var idx = this.indexOf(obj);
    if (idx > -1) {
        this.splice(idx, 1);
    }
}

现在我想在我的 main.ts 文件中全局应用该更改，如下所示：

import {Array<T>.remove} from "./utils.ts"

let arr = ["an", "array"];
arr.remove("array");

我可以导入接口声明，但对 Array 原型的更改在 main.ts 文件中不可用。如何对原型进行更改并将其全局应用或以某种方式导入“删除”功能？
