当我尝试使用正确的远程设置在 CFC 中调用这个简单函数时，我收到一条错误消息
“目的地‘ColdFusion’要么不存在，要么目的地没有定义通道，并且应用程序没有定义任何默认通道。”
这是CFC，虽然我 99% 肯定它不存在问题，非常简单。
<cfcomponent output="false">
<!--- Get Server Time --->

<cfreturn now() />
</cffunction>
<cffunction name="getString" access="remote" returnType="string">

这是 WEB-INF\flex 文件夹根目录下的services-services.xml文件。对于这个冗长乏味的文件，我深表歉意，但我认为问题可能出在其中。

当 main.mxml 文件编译运行时，调用 init() 方法，即使用远程对象连接调用 getString() 方法，返回并显示
警报框中的“[object AsyncToken]”。
如果单击该按钮，我将调用方法 getServerTime() 并尝试在 mxml 标签中显示服务器时间，但仅获取
如果我浏览到 ，我会得到一个白页。根据我遇到的一些线程，这应该是一件好事，试图解决这个问题。
main.mxml 文件和 cfc 位于项目的同一文件夹中。所以我知道远程调用正在查找 cfc。
我很确定问题出在 ColdFusion 的配置中，因为这是一个如此简单的请求。
