Pisces.IM.Client.Web(持续更新...)

Pisces.IM.Client.Web

　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　聊天界面

　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　历史记录

 

 

前端主要采用了knockout-3.5.1.js作为数据绑定

websocket作为前后主要通讯手段

需要在Program.cs加上一句启用websocket

1 app.UseWebSockets();

 

将封装ICommunicationService接口并作为单例模式注入，目的防止刷新导致与通讯服务刷新出现奇怪的bug

Program.cs中

1 builder.Services.AddSingleton<ICommunicationService, CommunicationService>();

在ICommunicationService.cs中

  1   public interface ICommunicationService
  2   {
  3       void SendMessage(ChatContentModel content);
  4 
  5       WebSocket? CurrentClient { get; }

  7       string MyID { get; }
  8 
  9       void SetCurrentClient(WebSocket client);

 12   public class CommunicationService : ICommunicationService
 13   {
 14       private readonly ICommunication _communication;
 15       private readonly IChatContentService _chatContentService;
 16       public string MyID { get; }
 17       public WebSocket? CurrentClient { get; private set; }

 19       public CommunicationService(ICommunication communication, IChatContentService chatContentService)
 20       {
 21           _communication = communication;
 22           _communication.ReceiveContentMessage += Communication_ReceiveContentMessage;
 23           MyID = _communication.GetID() ?? GenerateIdHelper.GenerateId().ToString();
 24           _chatContentService = chatContentService;
 25 
 26       }
 27 
 28       public async void Communication_ReceiveContentMessage(ContentMessageEventArgs e)
