Record Ocelot + SignalR multi server test

Keywords: ASP.NET JSON less

Preface

There are two projects, one gateway and one SignalR

Paste code

1,Gatway

1. Reference to Ocelot

2. Add a little code

Startup.cs

3. Simple configuration of ocelot

ocelot.json

{
  "ReRoutes": [
    {
      "DownstreamPathTemplate": "/{catchAll}", //Downstream path
      "DownstreamScheme": "ws", //https / / downstream protocol
      "DownstreamHostAndPorts": [ // Downstream host and port
        {
          "Host": "127.0.0.1",  // Here is the signal address after me
          "Port": 53353
        },
        {
          "Host": "127.0.0.1",
          "Port": 53354
        },
        {
          "Host": "127.0.0.1",
          "Port": 53355
        }
      ],
      "UpstreamPathTemplate": "/gateway/{catchAll}", // Upstream path
      "UpstreamHttpMethod": [ "GET", "POST", "PUT", "DELETE", "OPTIONS" ], //http method used upstream
      "LoadBalancerOptions": {
        "Type": "RoundRobin" //Rain and dew are evenly distributed.
        //Less tasks to receive customers
        //NoLoadBalance will be released to Sri Lanka
      }
    }
  ],
  "GlobalConfiguration": {  //Global configuration
    "BaseUrl": "http://127.0.0.1:5000"
  }
}

1,Startup.cs

2,chat.js

//const connection = new signalR.HubConnectionBuilder()
//    . withUrl("http://127.0.0.1:5000/gateway/chatHub") / / use HTTP here
//    .configureLogging(signalR.LogLevel.Information)
//    .build();

const connection = new signalR.HubConnectionBuilder()
    .withUrl("ws://127.0.0.1:5000/gateway/chatHub ", {/ / WebSockets are used here. Otherwise, it cannot be connected
        skipNegotiation: true,
        transport: signalR.HttpTransportType.WebSockets
    })
    .configureLogging(signalR.LogLevel.Trace)
    .build();

connection.on("ReceiveMessage", (user, message) => {
    const encodedMsg = user + " says " + message;
    const li = document.createElement("li");
    li.textContent = encodedMsg;
    document.getElementById("messagesList").appendChild(li);
});

document.getElementById("sendButton").addEventListener("click", event => {
    const user = document.getElementById("userInput").value;
    const message = document.getElementById("messageInput").value;
    connection.invoke("SendMessage", user, message).catch(err => console.error(err.toString()));
    event.preventDefault();
});

connection.start().catch(err => console.error(err.toString()));
