.Net 5:无法启动Ocelot，不支持身份验证提供程序

Question

我想在Ocelot API网关中实现JWT身份验证，我仔细地遵循了Ocelot文档，并实现了它。但我犯了一个错误，根本不知道该怎么解决。

我使用了文档的这一部分来启用身份验证。

我收到的错误：

System.AggregateException：'出现一个或多个错误。(无法启动Ocelot，错误为：身份验证选项AuthenticationProviderKey:BaseAuthenticationSchema，AllowedScopes:[]为不支持的身份验证提供商)的

使用过的包：

Ocelot(17.0.0)

Microsoft.AspNetCore.Authentication.JwtBearer(5.0.11)

还有我的代码部分，了解更多规范：

程序.cs :

public class Program
{
public static void Main(string[] args)
{
CreateHostBuilder(args).Build().Run();
}
public static IHostBuilder CreateHostBuilder(string[] args) =>
Host.CreateDefaultBuilder(args)
.ConfigureAppConfiguration((hostingContext, config) =>
{
config
.SetBasePath(hostingContext.HostingEnvironment.ContentRootPath)
.AddJsonFile("appsettings.json", optional: true, reloadOnChange: true)
.AddJsonFile($"appsettings.{hostingContext.HostingEnvironment.EnvironmentName}.json", optional: true, reloadOnChange: true)
.AddJsonFile($"ocelot.json", optional: false, reloadOnChange: true)
.AddEnvironmentVariables();
})
.ConfigureServices(s =>
{
s.AddOcelot();
})
.ConfigureWebHostDefaults(webBuilder =>
{
webBuilder.UseStartup<Startup>()
.UseSerilog((_, config) =>
{
config
.MinimumLevel.Information()
.MinimumLevel.Override("Microsoft", LogEventLevel.Warning)
.Enrich.FromLogContext()
.WriteTo.File(@"LogsAllHttpRequestsLog.txt", rollingInterval: RollingInterval.Day);
})
.Configure(app =>
{
app.UseMiddleware<HttpRequestsLoggingMiddleware>();
app.UseOcelot().Wait();
});
});
}

启动.cs:

public void ConfigureServices(IServiceCollection services)
{
// Adding Authentication
var baseAuthenticationProviderKey = "BaseAuthenticationSchema";
services.AddAuthentication(options =>
{
options.DefaultAuthenticateScheme = JwtBearerDefaults.AuthenticationScheme;
options.DefaultChallengeScheme = JwtBearerDefaults.AuthenticationScheme;
options.DefaultScheme = JwtBearerDefaults.AuthenticationScheme;
})
// Adding Jwt Bearer  
.AddJwtBearer(baseAuthenticationProviderKey, options =>
{
options.SaveToken = true;
options.RequireHttpsMetadata = false;
options.TokenValidationParameters = new TokenValidationParameters()
{
ValidateIssuer = true,
ValidateAudience = true,
ValidateIssuerSigningKey = true,
ValidateLifetime = true,
ValidAudience = "ValidAudience",
ValidIssuer = "ValidIssuer ",
IssuerSigningKey = new SymmetricSecurityKey(Encoding.UTF8.GetBytes("IssuerSigningKey"))
};
});
services.AddControllers();
services.AddOcelot(_configuration);
}

最后使用了ocelot的配置：

{
"DownstreamPathTemplate": "/api/v1/banks",
"DownstreamScheme": "https",
"DownstreamHostAndPorts": [
{
"Host": "localhost",
"Port": 44371
}
],
"UpstreamPathTemplate": "/api/market/banks",
"UpstreamHttpMethod": [ "Get" ],
"AuthenticationOptions": {
"AuthenticationProviderKey": "BaseAuthenticationSchema",
"AllowedScopes": []
}
}

我调查了所有的文章，也调查了像这个开放问题一样的ocelot GitHub页面，但我的问题没有解决。有人能帮我吗？

非常感谢。

最后，我用这个关于Ocelot GitHub页面打开问题的评论解决了我的问题。

刚刚将身份验证配置从上的startup.cs文件移动到program.cs文件。ConfigureServices部分。

像这样：

.ConfigureServices(s =>
{
// Adding Authentication
var baseAuthenticationProviderKey = "BaseAuthenticationSchema";
s.AddAuthentication(options =>
{
options.DefaultAuthenticateScheme = JwtBearerDefaults.AuthenticationScheme;
options.DefaultChallengeScheme = JwtBearerDefaults.AuthenticationScheme;
options.DefaultScheme = JwtBearerDefaults.AuthenticationScheme;
})
// Adding Jwt Bearer  
.AddJwtBearer(baseAuthenticationProviderKey, options =>
{
options.SaveToken = true;
options.RequireHttpsMetadata = false;
options.TokenValidationParameters = new TokenValidationParameters()
{
ValidateIssuer = true,
ValidateAudience = true,
ValidateIssuerSigningKey = true,
ValidateLifetime = true,
ValidAudience = "ValidAudience",
ValidIssuer = "ValidIssuer",
IssuerSigningKey = new SymmetricSecurityKey(Encoding.UTF8.GetBytes("Secret"))
};
});
s.AddOcelot();
})

此外，还从startup.cs类中删除了该配置。
