在ASP.Net Core SignalR中,如果你想在Negotiate请求中使用Bearer令牌进行身份验证,可以按照以下步骤进行操作:
public void ConfigureServices(IServiceCollection services)
{
// 添加身份验证服务
services.AddAuthentication(options =>
{
options.DefaultAuthenticateScheme = JwtBearerDefaults.AuthenticationScheme;
options.DefaultChallengeScheme = JwtBearerDefaults.AuthenticationScheme;
}).AddJwtBearer(options =>
{
// 设置令牌验证参数
options.TokenValidationParameters = new TokenValidationParameters
{
ValidateIssuer = true,
ValidateAudience = true,
ValidateLifetime = true,
ValidateIssuerSigningKey = true,
ValidIssuer = "your_issuer",
ValidAudience = "your_audience",
IssuerSigningKey = new SymmetricSecurityKey(Encoding.UTF8.GetBytes("your_secret_key"))
};
// 配置SignalR的认证方案
options.Events = new JwtBearerEvents
{
OnMessageReceived = context =>
{
var accessToken = context.Request.Query["access_token"];
// 如果请求中包含access_token参数,则将其设置为Bearer令牌
if (!string.IsNullOrEmpty(accessToken))
{
context.Token = accessToken;
}
return Task.CompletedTask;
}
};
});
services.AddSignalR();
}
public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
{
// 添加身份验证中间件
app.UseAuthentication();
app.UseRouting();
app.UseEndpoints(endpoints =>
{
endpoints.MapHub("/yourhub");
});
}
using (var httpClient = new HttpClient())
{
httpClient.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Bearer", "your_token");
var response = await httpClient.GetAsync("http://localhost:5000/yourhub/negotiate");
if (response.IsSuccessStatusCode)
{
var negotiateResponse = await response.Content.ReadAsStringAsync();
// 获取到Negotiate响应,并使用它连接到SignalR服务
// ...
}
}
请注意,上述代码中的“your_issuer”、“your_audience”和“your_secret_key”需要根据你的实际情况进行替换。此外,你还需要根据你的Hub的路径进行替换(例如,“/yourhub”)。
