C# 微信企业号聊天机器人:优化会话管理,提高响应速度
本文将介绍如何优化 C# 微信企业号聊天机器人代码,以提高其响应速度。
问题:
在处理大量的用户消息时,如果每次都重新创建会话实例,会导致性能下降。为了解决这个问题,可以使用 Dictionary 来存储每个 OpenId 对应的 ChatServiceInstance,这样可以快速查找到对应的会话实例,避免每次都需要重新创建。
优化方案:
- 使用
Dictionary存储会话实例:
private static Dictionary<string, ChatServiceInstance> chatServiceInstances = new Dictionary<string, ChatServiceInstance>();
- 在
OnTextRequestAsync方法中判断是否已存在当前OpenId的会话实例:
public override async Task<IWorkResponseMessageBase> OnTextRequestAsync(RequestMessageText requestMessage)
{
// ...
ChatServiceInstance chatServiceInstance;
if (chatServiceInstances.ContainsKey(OpenId))
{
chatServiceInstance = chatServiceInstances[OpenId];
}
else
{
// 创建会话
chatServiceInstance = GetChatServiceInstance();
chatServiceInstances.Add(OpenId, chatServiceInstance);
}
// ...
}
代码示例:
public override async Task<IWorkResponseMessageBase> OnTextRequestAsync(RequestMessageText requestMessage)
{
var responseMessage = this.CreateResponseMessage<ResponseMessageText>();
responseMessage.Content = '长途访问,请耐心等待回答 Ai生成它很快,但是由于网络问题我们需要等待,通常内容越长等待越久。';
if (requestMessage.Content.Length > 0)
{
try
{
Stopwatch stopwatch = Stopwatch.StartNew();
LogHelper.Debug($'{OpenId}:{requestMessage.Content}');
// 发送一条客服消息
var weixinSetting = Config.SenparcWeixinSetting.WorkSetting;
var appKey = AccessTokenContainer.BuildingKey(weixinSetting.WeixinCorpId, weixinSetting.WeixinCorpSecret);
ChatServiceInstance chatServiceInstance;
if (chatServiceInstances.ContainsKey(OpenId))
{
chatServiceInstance = chatServiceInstances[OpenId];
}
else
{
// 创建会话
chatServiceInstance = GetChatServiceInstance();
chatServiceInstances.Add(OpenId, chatServiceInstance);
}
var result = await chatServiceInstance.Ask(requestMessage.Content);
stopwatch.Stop();
MassApi.SendText(appKey, weixinSetting.WeixinCorpAgentId, result, OpenId);
LogHelper.Debug($'to_{OpenId}[{stopwatch.ElapsedMilliseconds}ms]:{result}');
}
catch (Exception ex)
{
LogHelper.Error(ex.Message);
LogHelper.Error(ex.StackTrace);
responseMessage.Content = '不好意思,发生错误了';
}
return responseMessage;
}
return responseMessage;
}
总结:
通过使用 Dictionary 来存储会话实例,可以有效提高聊天机器人的响应速度,提升用户体验。
