您需要对 JWT Bearer 事件进行特殊处理,以便您的身份验证正常工作。令牌需要转发到集线器。看看我说的部分
那部分不见了
public void ConfigureServices(IServiceCollection services)
{
services.AddDbContext<ApplicationDbContext>(options =>
options.UseSqlServer(Configuration.GetConnectionString("DefaultConnection")));
services.AddIdentity<ApplicationUser, IdentityRole>()
.AddEntityFrameworkStores<ApplicationDbContext>()
.AddDefaultTokenProviders();
services.AddAuthentication(options =>
{
// Identity made Cookie authentication the default.
// However, we want JWT Bearer Auth to be the default.
options.DefaultAuthenticateScheme = JwtBearerDefaults.AuthenticationScheme;
options.DefaultChallengeScheme = JwtBearerDefaults.AuthenticationScheme;
})
.AddJwtBearer(options =>
{
// Configure JWT Bearer Auth to expect our security key
options.TokenValidationParameters =
new TokenValidationParameters
{
LifetimeValidator = (before, expires, token, param) =>
{
return expires > DateTime.UtcNow;
},
ValidateAudience = false,
ValidateIssuer = false,
ValidateActor = false,
ValidateLifetime = true,
IssuerSigningKey = SecurityKey
};
//THAT IS THE PART WHICH IS MISSING IN YOUR CONFIG !
// We have to hook the OnMessageReceived event in order to
// allow the JWT authentication handler to read the access
// token from the query string when a WebSocket or
// Server-Sent Events request comes in.
options.Events = new JwtBearerEvents
{
OnMessageReceived = context =>
{
var accessToken = context.Request.Query["access_token"];
// If the request is for our hub...
var path = context.HttpContext.Request.Path;
if (!string.IsNullOrEmpty(accessToken) &&
(path.StartsWithSegments("/hubs/chat")))
{
// Read the token out of the query string
context.Token = accessToken;
}
return Task.CompletedTask;
}
};
});
services.AddMvc().SetCompatibilityVersion(CompatibilityVersion.Version_2_1);
services.AddSignalR();
// Change to use Name as the user identifier for SignalR
// WARNING: This requires that the source of your JWT token
// ensures that the Name claim is unique!
// If the Name claim isn't unique, users could receive messages
// intended for a different user!
services.AddSingleton<IUserIdProvider, NameUserIdProvider>();
// Change to use email as the user identifier for SignalR
// services.AddSingleton<IUserIdProvider, EmailBasedUserIdProvider>();
// WARNING: use *either* the NameUserIdProvider *or* the
// EmailBasedUserIdProvider, but do not use both.
