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:

  1. 使用 Dictionary 存储会话实例:
private static Dictionary<string, ChatServiceInstance> chatServiceInstances = new Dictionary<string, ChatServiceInstance>();
  1. 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。
