AS3文件系统的Hello World [英] AS3 Filesystem Hello World

问题描述

我想用的ActionScript3写的Hello World到一个文本文件中。我想编译和运行的命令行code。

I would like to use ActionScript3 to write "Hello World" to a text file. I'd like to compile and run that code from the command line.

安装：WINDOWS 10，Adobe AIR的SDK 18.0，flex_sdk_4.6

Installed: Windows 10, Adobe AIR 18.0 SDK, flex_sdk_4.6

（TLDR：我想要做自动化测试的一个更大的一块code命令行，当然我想不通这片）

(TLDR: I want to do automated testing for a much larger piece of code from the command line, and of course I can't figure out this piece)

我错过了一些步骤，我想不通。这是我的code：

I am missing some steps that I can't figure out. Here's my code:

MainF.as

package {
    import flash.display.*;
    import flash.text.*;
    import flash.filesystem.*;

    public class MainF extends Sprite
    {
        public function MainF()
        {
            var file:File =  new File("output.txt");
            var stream:FileStream = new FileStream();
            stream.open(file, FileMode.WRITE);
            stream.writeUTFBytes("Hello World!");
            stream.close();
        }
    }
}

我第一次运行这个命令：

I ran this command first:

amxmlc MainF.as -dump-config aircfg.xml

，现在我用这个来编译我的项目：

And now I am using this to compile my project:

amxmlc MainF.as -load-config aircfg.xml

我的AirSdk \ bin路径是在我的PATH环境变量，因此它找到AirSdk \ BIN \ amxmlc.bat正确。

My AirSdk\bin path is in my PATH environment variable, so it finds AirSdk\bin\amxmlc.bat correctly.

我曾尝试与空气中的编译器（如上图所示）和Flex编译器（flex_sdk_4.6 \ BIN \ mxmlc.exe）编制本。一切我都试过了这个错误：

I have tried compiling this with the air compiler (shown above) and the flex compiler (flex_sdk_4.6\bin\mxmlc.exe). Everything I have tried has this error:

Warning: No definitions matching flash.filesystem.* could be found.
        import flash.filesystem.*;

这个答案并没有解决我的问题： <一href="http://stackoverflow.com/questions/5446536/flash-builder-1172-definition-could-not-be-found">Flash制造商：1172定义找不到

This answer has not resolved my issue: Flash Builder: 1172 Definition Could not be found

我需要更具体的说明，我是很新的AS3。而且，正如我所说，我需要编译和命令行运行时，它的工作。

I need much more specific instructions, I'm very new to AS3. And, as I said, I need it to work when compiled and run from the command line.

推荐答案

最有用的帮助页面开始：

Starting with the most useful help page:

的http://help.adobe.com/en_US/air/build/WS901d38e593cd1bac25d3d8c712b2d86751e-8000.html

这里所有的指令都是不错的，保存在HelloWorld.xml一行。替换：

All the instructions here are good, save one line in HelloWorld.xml. Replace:

<application xmlns="http://ns.adobe.com/air/application/2.7">

使用：

<application xmlns="http://ns.adobe.com/air/application/18.0">

presumably这应该与AirSDK您已在计算机上安装的版本。

Presumably this should match the version of AirSDK that you have installed on your machine.

创建flexcfg.xml：

Create flexcfg.xml:

mxmlc -dump-config flexcfg.xml

这将引发编译器错误，忽略它们。会有很多问题，这个文件，这需要加以固定。一些路​​径将无法正确设置：

This will throw compiler errors, ignore them. There will be many problems with this file, which need to be fixed. Several paths will not be set correctly:

<path-element>libs</path-element>

（和其他人，都开始以＆lt;路径元素>） 这将引用文件从AirSDK，但它不会正确地引用它们。 我把完整路径到我的本地AirSDK：

(and others, all starting with < path-element >) These will reference files from your AirSDK, but it will not reference them correctly. I put the full path to my local AirSDK:

<path-element>C:/dev/AirSdk/frameworks/libs</path-element>

这条道路将是唯一的你安装AirSDK的。再次，将有几个这样的，解决所有这些，散落的文件中。

This path will be unique to your installation of the AirSDK. Once again, there will be several of these, fix all of them, scattered in the file.

这得到一个基本的hello-world工作。现在，对于文件访问的一部分，这个环节提供了解决方案的一部分：

This gets a basic hello-world working. Now, for the file-access part, this link provides part of the solution:

<一个href="http://stackoverflow.com/questions/5446536/flash-builder-1172-definition-could-not-be-found">Flash制造商：1172定义找不到

具体而言，再次在flexcfg.xml文件，你需要找到这一行：

Specifically, once again in your flexcfg.xml file, you need to find this line:

<external-library-path>

和另起一行在它下面：

<path-element>C:/dev/AirSdk/frameworks/libs/air/airglobal.swc</path-element>

（再次，您的AirSdk可以被安装在其他目录）

(once again, your AirSdk may be installed in another directory)

有几个地方，会给你必要的行写的Hello World到一个文件，这里有一个： 保存字符串在AS3 文本文件 请确保您使用writeUTFBytes作为答案显示，而不是问题。

There are several places that will give you the necessary lines to write "Hello World" to a file, here's one: Saving string to text file in AS3 Make sure you use "writeUTFBytes" as the answer indicates, rather than the question.

HelloWorld.as的最终版本是这样的：

The final version of HelloWorld.as looks like this:

package
{
    import flash.display.Sprite;
    import flash.text.*;
    import flash.filesystem.*;

    public class HelloWorld extends Sprite
    {
        public function HelloWorld()
        {
            var textField:TextField = new TextField();
            stage.addChild( textField );
            textField.text = "Hello, World!";

            var outputFile:File = new File("C:/depot/sdks/ActionScriptSDK/HelloWorld/output.txt");
            var stream:FileStream = new FileStream();
            stream.open(outputFile, FileMode.WRITE);
            stream.writeUTFBytes("Hello, File World!");
            stream.close();
        }
    }
}

flexcfg.xml主要是自动生成的。这是一个长的文件，我不会分享这一切，但我会分享一些相关的行：

flexcfg.xml is MOSTLY generated automatically. It's a long file, I won't share it all, but I will share some relevant lines:

<external-library-path>
    <path-element>C:/dev/AirSdk/frameworks/libs/player/{targetPlayerMajorVersion}.{targetPlayerMinorVersion}/playerglobal.swc</path-element>
    <path-element>C:/dev/AirSdk/frameworks/libs/air/airglobal.swc</path-element>
</external-library-path>

和后来在文件中：

<library-path>
    <path-element>C:/dev/AirSdk/frameworks/libs</path-element>
    <path-element>C:/dev/AirSdk/frameworks/locale/{locale}</path-element>
</library-path>

HelloWorld.xml几乎复制从help.adobe.com一糊，但在这里它是：

HelloWorld.xml is almost copy paste of the one from help.adobe.com, but here it is:

<?xml version="1.0" encoding="UTF-8"?>
<application xmlns="http://ns.adobe.com/air/application/18.0">
    <id>samples.android.HelloWorld</id>
    <versionNumber>0.0.1</versionNumber>
    <filename>HelloWorld</filename>
    <initialWindow>
        <content>HelloWorld.swf</content>
    </initialWindow>
    <supportedProfiles>mobileDevice</supportedProfiles>
</application>

最后，将其包装成一个步骤，GO.BAT：

Finally, to wrap it up into one step, go.bat:

call mxmlc HelloWorld.as -load-config flexcfg.xml
call adl HelloWorld.xml
