AI 解决方案
🔍 报错分析
1. 🌐 错误翻译
原文:Error handling request: /client/items
The operation was canceled.
译文:处理请求时出错:/client/items
该操作已被取消
2. 🎯 原因分析
/client/items接口的JSON流式序列化过程中,CancellationToken被触发取消SptHttpListener.SendStreamedJsonAsync方法执行JSON序列化时,客户端或服务端主动取消了操作(可能因超时、连接中断或主动取消请求)3. 💡 解决方案
// 在调用SendStreamedJsonAsync前增加取消逻辑判断
if (cancellationToken.IsCancellationRequested)
{
// 提前返回或执行备选逻辑,避免进入序列化流程
return;
}
// 或在序列化方法中增加取消响应的处理
try
{
await jsonTypeInfo.SerializeAsync(
pipeWriter,
rootValue,
flushThreshold,
cancellationToken,
rootValueBoxed);
}
catch (OperationCanceledException)
{
// 捕获取消异常并释放资源
await pipeWriter.FlushAsync(cancellationToken);
// 记录日志或返回特定状态码
}
