如何在 HTTPService 故障处理程序中获取 HTTP 状态代码

发布于 2024-08-28 00:02:54 字数 818 浏览 7 评论 0原文

我从客户端通过 HTTPService 调用服务器方法。服务器是一个 RestFul Web 服务，它可能会使用许多 HTTP 错误代码之一进行响应（例如，一个错误为 400，另一个错误为 404，另一个错误为 409）。我一直在尝试找出确定服务器发送的确切错误代码的方法。我已经遍历了故障处理程序中填充的FaultEvent 的整个对象树，但它没有告诉我错误代码。 Flex 中缺少此功能吗？

我的代码如下所示： HTTP 服务声明：

    <mx:HTTPService id="myServerCall" url="myService" method="GET" 
resultFormat="e4x" result="myServerCallCallBack(event)" fault="faultHandler(event)">
            <mx:request>
                <action>myServerCall</action>
                <docId>{m_sDocId}</docId>
            </mx:request>
        </mx:HTTPService>

我的错误处理程序代码如下所示：

private function faultHandler(event : FaultEvent):void
{
 Alert.show(event.statusCode.toString() + " / " + event.fault.message.toString()); 
}

I am calling a server method through HTTPService from client side. The server is a RestFul web service and it might respond with one of many HTTP error codes (say, 400 for one error, 404 for another and 409 for yet another). I have been trying to find out the way to determine what was the exact error code sent by the server. I have walked teh entire object tree for the FaultEvent populated in my fault handler, but no where does it tell me the error code. Is this missing functionality in Flex?

My code looks like this:
The HTTP Service declaration:

    <mx:HTTPService id="myServerCall" url="myService" method="GET" 
resultFormat="e4x" result="myServerCallCallBack(event)" fault="faultHandler(event)">
            <mx:request>
                <action>myServerCall</action>
                <docId>{m_sDocId}</docId>
            </mx:request>
        </mx:HTTPService>

My fault handler code is like so:

private function faultHandler(event : FaultEvent):void
{
 Alert.show(event.statusCode.toString() + " / " + event.fault.message.toString()); 
}

我可能在这里遗漏了一些东西，但是：

event.statusCode

为我提供了 HTTP 响应的状态代码。

所以我可以在我的故障处理函数中成功地执行类似的操作：

public function handleFault(faultEvent:FaultEvent):void
{
    if (faultEvent.statusCode == 401)
    {
        Alert.show("Your session is no longer valid.", "", Alert.OK, this, loginFunc);
    }
    else
    {
        Alert.show("Failed with error code: " + faultEvent.statusCode as String);
    }
}

I might be missing something here, but:

event.statusCode

gives me the status code of the HTTP response.

So I can successfully do something like this in my fault handler function:

public function handleFault(faultEvent:FaultEvent):void
{
    if (faultEvent.statusCode == 401)
    {
        Alert.show("Your session is no longer valid.", "", Alert.OK, this, loginFunc);
    }
    else
    {
        Alert.show("Failed with error code: " + faultEvent.statusCode as String);
    }
}
