与JS客户端上的accessTokenFactory的SignalR连接不与connectionId和UserIdentifier连接，但.Net客户端很好

Question

在我的SignalR Authentication原型中，JS客户端没有Context.UserIdentifier，连接到JS客户端侧的SignalR集线器时connectionId将为0。它适用于.NET客户端。

想知道构建连接是否错误？这是我的联系：

state.connection = new signalR.HubConnectionBuilder()
                .withUrl("/chatHub", {
                    accessTokenFactory: async () => {
                        axios.post('https://localhost:44384/api/account/token', { email: email, password: password })
                            .then(async (response) => {
                                if (typeof response === 'undefined') {
                                    return;
                                }
                                else {
                                    console.log(response.data);
                                    console.log(state.connection.id);
                                    return response.data;
                                }
                            })
                            .catch((error) => {
                                console.log(error);
                            });
                    }
                })
                .build();   

WPF客户端使用以下代码与令牌连接：

_connection = new HubConnectionBuilder()
            .WithUrl("https://localhost:44384/ChatHub", options =>
            {
                options.AccessTokenProvider = async () =>
                {
                    var tokenUserCommand = new TokenUserCommand
                    {
                        Email = emailTextBox.Text,
                        Password = passwordBox.Password
                    };

                    var token = await RestService.PostAsync<string>("account/token", tokenUserCommand);
                    return token;
                };

            })
            .Build();

我在哪里找到了SignalR Authentication configuration和SignalR Bearer Authentication

这是source for my prototype project

请求令牌的JS客户端在axios.post之前只需要一个await关键字。这样一个新手的错误花费的时间比它应该有的多。

state.connection = new signalR.HubConnectionBuilder()
            .withUrl("https://localhost:44384/ChatHub", {
                accessTokenFactory: async () => {
                    if (state.accessToken === null) {
                        await axios.post('https://localhost:44384/api/account/token', { email: email, password: password })
                            .then(async (response) => {
                                if (typeof response === 'undefined') {
                                    return;
                                }
                                else {
                                    state.accessToken = response.data;
                                }
                            })
                            .catch((error) => {
                                console.log(error);
                            });
                    }
                    return state.accessToken;
                }
            })
            .build();
