function onUrlEvent(event as Object)
    if event.GetStatusCode() = 0 then
        ' 连接断开，抛出错误消息
        throw createErrorNode("Connection Error", "连接已断开")
    end if
end function

function createErrorNode(title as String, message as String) as Object
    errorNode = CreateObject("roSGNode", "ContentNode")
    errorNode.SetFields({
        title: title,
        message: message
    })
    return errorNode
end function

try
    ' 进行网络请求和连接
catch e as Object
    if e.GetMessage() = "连接已断开" then
        ' 处理连接断开的情况
    else
        ' 处理其他错误
