Question

我已经按照this和this或this教程在.net核心中构建了一个WebSocket Web应用程序。现在我试图通过使用Microsoft.AspNetCore.TestHost

来对此进行一些集成测试

我创建WebSocket的方式

String

websocket客户端创建在下面的代码中完成

public static WebSocketClient StartWebSocketServer(string url)
{
    var baseAddress = $"http://{url}";
    var builder =
        WebHost.CreateDefaultBuilder(new string[]{})
            .UseEnvironment("Development")
            .ConfigureLogging((ctx, logging) => logging.AddConsole())
            .UseUrls(baseAddress)
            .UseStartup<SocketsTestStartup>();

    var server = new TestServer(builder);
    return server.CreateWebSocketClient();
}

ClientWebSocket testAppClient = new ClientWebSocket(); await testAppClient .ConnectAsync( new Uri("ws://loclahost:52015/local"), CancellationToken.None);是websocket服务器上的路径名

Startup.cs

local

无论如何，连接产生以下错误

app.MapWebSocketManager(
    "/local",
    serviceProvider.GetService<LocalServiceSocketHandler>());

我的问题是如何让System.Net.WebSockets.WebSocketException : Unable to connect to the remote server与ClientWebSocket联系？

Answer 1

我使用以下代码运行WebSocket Web应用程序

，而不是TestServer

public static IWebHost CreateServer(int port)
{
    var configBuilder = new ConfigurationBuilder();
    configBuilder.AddInMemoryCollection();
    var config = configBuilder.Build();
    config["server.urls"] = $"http://localhost:{port}";

    var host = new WebHostBuilder()
        .ConfigureLogging((ctx, logging) => logging.AddDebug())
        .UseConfiguration(config)
        .UseKestrel()
        .UseStartup<SocketsTestStartup>()
        .Build();

    host.Start();

    return host;
}

基本上，我已经从aspnet/WebSockets测试中找到了解决方案

使用TestServer以下工作在我的最后，以防它可以帮助其他人，这是代码：

var builder = WebHost.CreateDefaultBuilder()
                .UseStartup<Startup>()
                .UseEnvironment("Development");

var server = new TestServer(builder);
var wsClient = server.CreateWebSocketClient();

var wsUri = new UriBuilder(server.BaseAddress) 
{
    Scheme = "ws"
}.Uri;

await wsClient.ConnectAsync(wsUri, CancellationToken.None);

但由于最初的问题是使用路径/local，因此只需要指定Path属性：

var wsUri = new UriBuilder(server.BaseAddress) 
{
    Scheme = "ws",

    Path = "local"
}.Uri;

此代码适用于我们开发的企业级应用（请参阅此处的所有代码：https://github.com/saturn72/Programmer）

//Create test server    
var server = new TestServer(builder);

//create websocket client, connect it and to server 
var wsc = server.CreateWebSocketClient();
var uri = new Uri(BaseUri, "ws");
var webSocket = wsc.ConnectAsync(uri, CancellationToken.None).Result;
var buffer = WebSocket.CreateClientBuffer(1024, 1024);

//Start receive data
Task.Run(()=> WebSocket.ReceiveAsync(_buffer, CancellationToken.None));

请记住它是async，你需要在测试中设置一些延迟

使用ClientWebSocket .net核心测试TestHost.WebSocketClient
