amchart学习笔记

Joomla使用过程中使用到分析组件(com_analytics)，已经相关的的插件!

插件当中使用到了amchart (真复杂...)

以下是amchart相关资料

总的来说：

amcharts 要一个“配置文件”（setting.xml），一个数据文件(amile_data.xml)，一个 SWFObject.js，一个对应的 SWF 就可以生成漂亮的统计报表了

1 SWFObject v1.5的对象结构

FlashObject = deconcept.SWFObject;
SWFObject = deconcept.SWFObject;

2 数据文件
支持csv、xml格式。
csv实际上是一个文本文件，而非excel文件，所以，可以直接使用文本文件来命名。
每一列的数据采用“;”或“,”分隔都可以。
例如：
// amcolumn_data.txt
2003;2.5
2004;4.6
2005;5.8
2006;3.8
2007;4.8
2008;6.8
2009;7.8

3 配置文件
例如：view plaincopy to clipboardprint?
// amcolumn_settings.xml  
<?xml version="1.0" encoding="UTF-8"?> 
<settings> 
   <!-- chart config --> 
   <data_type>csv</data_type>                                                     <!-- [xml] (xml / csv) -->

4 在HTML上显示

view plaincopy to clipboardprint?

<!-- amcolumn script--> 
<div id="flashcontent"> 
  <strong>You need to upgrade your Flash Player</strong>

  var so = new SWFObject("/amchart/amchart/amcolumn/amcolumn.swf", "amcolumn", "520", "380", "8", "#FFFFFF"); // 创建SWFObject对象  
  so.addVariable("path", "/amchart/amchart/amcolumn/"); // 暂时不是很清楚，破解时用到了这个属性。既然，例子写了，我们也写好了。  
  so.addVariable("settings_file", encodeURIComponent("amcolumn_settings.xml")); // 配置文件  
  so.addVariable("data_file", encodeURIComponent("amcolumn_data.txt")); // 数据文件  
  so.addVariable("preloader_color", "#000000"); // 加载时显示的颜色  
  so.write("flashcontent"); // 在flashcontent位置写入flash插入的HTML  
// --></mce:script> 
<!-- end of amcolumn script -->

5 破解amchart
没有破解的amchart显示的时候在左上角会出现“chart by amCharts.com”链接，表示是未注册版本，非常讨厌。
原理：网上看到的。
用SWF Decompiler软件加载swf文件，在Resources下找Action中的MainMoive，代码中有一段如下：
view plaincopy to clipboardprint?
function checkKey(serial)  
{  
   var _l1 = com.amcharts.Utils.stripSymbols(serial, " ");  
   _l1 = com.amcharts.Utils.stripSymbols(_l1, "/n");  
   _l1 = com.amcharts.Utils.stripSymbols(_l1, "/r");  
   _l1 = com.amcharts.Utils.stripSymbols(_l1, "/r/n");  
   arr = _l1.split("-");  
   if (Number(arr[2]) + Number(arr[3]) != 8645 || Number(arr[2].substr(1, 1)) - Number(arr[3].substr(2, 1)) != 2) 
   {  
       attachMovie("copyright_mc", "copyright_mc", 1001);  
   } // end if  
} // End of the function 
function checkKey(serial)
{
   var _l1 = com.amcharts.Utils.stripSymbols(serial, " ");
   _l1 = com.amcharts.Utils.stripSymbols(_l1, "/n");
   _l1 = com.amcharts.Utils.stripSymbols(_l1, "/r");
   _l1 = com.amcharts.Utils.stripSymbols(_l1, "/r/n");
   arr = _l1.split("-");
   if (Number(arr[2]) + Number(arr[3]) != 8645 || Number(arr[2].substr(1, 1)) - Number(arr[3].substr(2, 1)) != 2)
   {
       attachMovie("copyright_mc", "copyright_mc", 1001);
   } // end if
} // End of the function
这就是序列号的代码，再往下看
key_loader.loadVars(path + "amcharts_key.txt", this, "checkKey", false, "checkKey");
破解：
在swf目录下，新建文件amcharts_key.txt。
输入序列号内容如下：0000-0000-1422-7223。
保存后测试通过！真没想到他们会采用这么简单的加密方式！

注意：测试的时候发现一个问题，即使amcharts_key.txt正确放入SWF文件目录下，也有破解不成功的情况。
1）amcolumn, amline, ampie破解时跟so.addVariable("path", "");有关系。该属性设置错误破解不成功。
2）amstock似乎无法破解！

以上是网上贴的
