我是 FLEX 4 的新手和新手开发人员。
我正在尝试通过 usint HTTPService 将 XML 数据检索到 ArrayCollection 类中。但我收到一条错误消息“Http Request Error”
我想优雅地解决它。有什么推荐吗???
这是 XML 代码。
<?xml version="1.0" encoding="utf-8"?>
<products>
<product id="p1">
<name>1100</name>
<manufacturer>Nokia</manufacturer>
<price>2000</price>
<imageURL>1100.jpg</imageURL>
<description>Nokia 1100</description>
</product>
<product id="p2">
<name>1110</name>
<manufacturer>Nokia</manufacturer>
<price>2100</price>
<imageURL>1110.jpg</imageURL>
<description>Nokia 1110</description>
</product>
</products>
这是一个源文件:
