SignalR Core不生成(映射)客户端方法

SignalR Core正在生成Hub代理脚本,但没有添加"客户端"方法。 (服务器或客户端没有错误 - 只是不工作)

<script src="http://localhost/signalr/hubs">

生成JS
proxies['messageHub'] = this.createHubProxy('messageHub'); 
proxies['messageHub'].client = { };
proxies['messageHub'].server = {
        handleMessage: function (receivedString) {
            return proxies['messageHub'].invoke.apply(proxies['messageHub'], $.merge(["HandleMessage"], $.makeArray(arguments)));
         }
    };

这是服务器端的集线器:

public class MessageHub : Hub
{
    public void HandleMessage(string receivedString)
    {
        var responseString = string.Empty;

        MessageHandler.HandleMessage(receivedString, ref responseString);

        Clients.All.sendMessage(responseString);

    }
}

sendMessage 方法应该包含在JS文件的messageHub客户端代理中。      $。connection.messageHub.client.sendMessage未定义

仅创建(并且正常)服务器代理的 handleMessage

这里是SignalR的StartUp.cs包含:

ConfigureServices:

services.AddMvc(options =>
        {
            options.Filters.Add(new RoleFilterAttribute());
        }).AddJsonOptions(options => options.SerializerSettings.ContractResolver =
                new DefaultContractResolver());
services.AddSignalR(options => options.Hubs.EnableDetailedErrors = true)

配置:

app.UseWebSockets();
app.UseSignalR();

project.json:

"Microsoft.AspNetCore.Mvc": "1.0.0-*",
"Microsoft.AspNetCore.WebSockets": "1.0.0",
"Microsoft.AspNetCore.SignalR.Server": "0.2.0-*",

一些额外的工作:

1 - 在服务器端更改方法案例以查看它是否已映射:

Clients.All.SendMessage(responseString);

没用!

2 - 将客户端更改为动态映射:

var connection = $.hubConnection('http://localhost/');
var proxy = connection.createHubProxy('messageHub');
connection.start({ withCredentials: false }).done(function () { console.log("CONNECTED") });
proxy.on("sendMessage", function (result) {console.log(result);});
proxy.invoke("handleMessage", msg).done(function(result)console.log(result);});

再次只有handleMessage(服务器)工作。

答案 0 :(得分:0)

根据文档,您缺少方法名称,因此“发送所有”行应如下所示

public void HandleMessage(string receivedString)
{
    var responseString = string.Empty;

    MessageHandler.HandleMessage(receivedString, ref responseString);

    Clients.All.SendMessage("SendMessage",responseString);

}

以下也是正确的方法

app.UseSignalR(routes =>
        {
            routes.Hub<MessageHub>("/messageHub");
        });

最后

    var connection = $.hubConnection('http://localhost/');
var proxy = connection.createHubProxy('messageHub');
connection.start({ withCredentials: false }).done(function () { console.log("CONNECTED") });
proxy.on("SendMessage", function (result) {console.log(result);});
proxy.invoke("HandleMessage", msg).done(function(result)console.log(result);});
