AS3 对象转 JSON [英] AS3 Object To JSON
问题描述
我正在尝试将对象数组(嵌套)转换为 JSON 字符串.这是我的 JSON 输出:
I'm trying to convert an array of objects (nested) to JSON string. Here is my JSON output:
[{
"Width": 570,
"SessionID": 2003404006158805,
"Price": "69,90",
"PageCount": 24,
"Pages": [{
"ID": 1,
"TemplateID": 0,
"PageType": "cover",
"TextContainers": [],
"ImageContainers": []
}, {
"ID": 2,
"TemplateID": 1001,
"PageType": "single",
"TextContainers": [],
"ImageContainers": []
}, {
"ID": 3,
"TemplateID": 0,
"PageType": "double",
"TextContainers": [],
"ImageContainers": [{
"Width": 570,
"IsBG": true,
"Brightness": 0,
"Contrast": 0,
"PosX": null,
"ScaleX": null,
"Height": 284,
"ID": -1,
"BlackWhite": 0,
"PosY": null,
"HasPhoto": false,
"ScaleY": null,
"PhotoID": null
}]
}, {
"ID": 4,
"TemplateID": 0,
"PageType": "double",
"TextContainers": [],
"ImageContainers": [{
"Width": 570,
"IsBG": true,
"Brightness": 0,
"Contrast": 0,
"PosX": null,
"ScaleX": null,
"Height": 284,
"ID": -1,
"BlackWhite": 0,
"PosY": null,
"HasPhoto": false,
"ScaleY": null,
"PhotoID": null
}]
}],
"ProductSubID": 0,
"Height": 620,
"ProductID": 0
}]
当我尝试将此字符串转换为 XML(在服务器端)时，结果如下:
And when I'm trying to convert this string to XML (at server side) comes out like this:
<?xml version="1.0" encoding="UTF-8" ?>
<0>
<Width>570</Width>
<SessionID>2003404006158805</SessionID>
<Price>69,90</Price>
<PageCount>24</PageCount>
<Pages>
<ID>1</ID>
<TemplateID>0</TemplateID>
<PageType>cover</PageType>
</Pages>
<Pages>
<ID>2</ID>
<TemplateID>1001</TemplateID>
<PageType>single</PageType>
</Pages>
<Pages>
<ID>3</ID>
<TemplateID>0</TemplateID>
<PageType>double</PageType>
<ImageContainers>
<Width>570</Width>
<IsBG>true</IsBG>
<Brightness>0</Brightness>
<Contrast>0</Contrast>
<PosX />
<ScaleX />
<Height>284</Height>
<ID>-1</ID>
<BlackWhite>0</BlackWhite>
<PosY />
<HasPhoto>false</HasPhoto>
<ScaleY />
<PhotoID />
</ImageContainers>
</Pages>
<Pages>
<ID>4</ID>
<TemplateID>0</TemplateID>
<PageType>double</PageType>
<ImageContainers>
<Width>570</Width>
<IsBG>true</IsBG>
<Brightness>0</Brightness>
<Contrast>0</Contrast>
<PosX />
<ScaleX />
<Height>284</Height>
<ID>-1</ID>
<BlackWhite>0</BlackWhite>
<PosY />
<HasPhoto>false</HasPhoto>
<ScaleY />
<PhotoID />
</ImageContainers>
</Pages>
<ProductSubID>0</ProductSubID>
<Height>620</Height>
<ProductID>0</ProductID>
</0>
但我需要它像:
<pages>
<page>
</page>
<page>
</page>
</pages>
这是我将 Object 数组转换为 JSON 的 AS 代码
This is my AS code to convert Object arrays into JSON
var Pages:Array = [];
var Books:Array = [];
var JBook:Object = new Object();
JBook.Width = Global.BOOK_WIDTH;
for(var i:Number = 0; i<Global.PAGES.length; i++)
{
var Page:PageVO = Global.PAGES[i] as PageVO;
var JPage:Object = new Object();
JPage.ID = Page.ID;
var ImageContainers:Array = [];
var TextContainers:Array = [];
var Template:TemplateVO = Page.ACTIVE_TEMPLATE;
for(var j:Number = 0; j<Template.IMAGE_CONTAINERS.length; j++)
{
var ImageContainer:ImageContainerVO = Template.IMAGE_CONTAINERS[j] as ImageContainerVO;
var JImageContainer:Object = new Object();
JImageContainer.ID = ImageContainer.ID;
ImageContainers.push(JImageContainer);
}
for (var m:Number = 0; m<Template.TEXT_CONTAINERS.length; m++)
{
var TextContainer:TextContainerVO = Template.TEXT_CONTAINERS[m] as TextContainerVO;
var JTextContainer:Object = new Object();
JTextContainer.ID = TextContainer.ID;
}
JPage.TextContainers = TextContainers;
JPage.ImageContainers = ImageContainers;
Pages.push(JPage);
}
var Photos:Array = [];
for(var p:Number = 0; p<Global.PHOTOS.length; p++ )
{
var Photo:PhotoVO = Global.PHOTOS[p] as PhotoVO;
var JPhoto:Object = new Object();
JPhoto.BMP = ImageUtils.BitmapToBase64(Photo.BMP.bitmapData);
JPhoto.UseCount = Photo.USE_COUNT;
JPhoto.ID = Photo.ID;
Photos.push(JPhoto);
}
//JBook.Photos = Photos;
JBook.Pages = Pages;
JSON = com.adobe.serialization.json.JSON.encode(Books);
知道为什么它渲染 JSON 字符串就像它们不在同一个节点中一样(每个页面项目都有单独的节点)?
Any idea why it's rendering JSON string like they are not in the same node (seperate node for every page item)?
希望我已经清楚了.谢谢.
Hope I've been clear. Thanks.
推荐答案
从 AS3 对象转换为 JSON 字符串的最简单方法可能是使用 来自 as3corelib 的 JSON 类.
Probably the easiest way to convert from an AS3 object to a JSON string is to use the JSON class from as3corelib.
示例用法:
var jsonString:String = JSON.encode(myDataObject);
最好不要编写自己的解析器，因为 as3corelib JSON 解析器已经被很多人研究并使用了很长时间.
It is probably best not to write your own parser, as the as3corelib JSON parser has been worked on and used by many people, for quite some time.
@dpcao 提到您甚至不再需要外部库，Adobe 在 FlashPlayer 11 中引入了一个新的 JSON 类.
@dpcao mentioned that you don't even need an external library anymore, Adobe introduced a new JSON class available in FlashPlayer 11.
示例用法:
var jsonString:String = JSON.stringify(myDataObject);
