我将身份验证服务生成的令牌用于我的应用程序。这没什么问题。现在，我已经引入Swashbuckle来记录我的API，我可以通过使用下面的代码向每个请求发送JWT来进行如下身份验证；

services.AddSwaggerGen(c =>
{
    var a = new ApiKeyScheme();
    //c.AddSecurityDefinition("Bearer", new ApiKeyScheme()
    //{ In = "header", Description = "Please insert JWT with Bearer into field", Name = "Authorization", Type = "apiKey" });

    c.OperationFilter<AuthorizationHeaderParameterOperationFilter>();

    c.SwaggerDoc("v2", new Info
    {
        Version = "v2",
        Title = "MyTitle",
        Description = "An interface for ...",
        TermsOfService = "None",
        Contact = new Contact() { Name = "MyApp", Email = "a@example.com", Url = "www.example.com" }
    });
    // Set the comments path for the Swagger JSON and UI.
    var basePath = AppContext.BaseDirectory;
    var xmlPath = Path.Combine(basePath, "cpDataCore.xml");
    c.IncludeXmlComments(xmlPath);
});

public class AuthorizationHeaderParameterOperationFilter : IOperationFilter
{
    public void Apply(Operation operation, OperationFilterContext context)
    {
        var filterPipeline = context.ApiDescription.ActionDescriptor.FilterDescriptors;
        var isAuthorized = filterPipeline.Select(filterInfo => filterInfo.Filter).Any(filter => filter is AuthorizeFilter);
        var allowAnonymous = filterPipeline.Select(filterInfo => filterInfo.Filter).Any(filter => filter is IAllowAnonymousFilter);

        if (isAuthorized && !allowAnonymous)
        {
            if (operation.Parameters == null)
                operation.Parameters = new List<IParameter>();

            operation.Parameters.Add(new NonBodyParameter
            {
                Name = "Authorization",
                In = "header",
                Description = "access token",
                Required = true,
                Type = "string"
            });
        }
    }
}

这给了我下面的头--不出所料

虽然，我不确定Cookie是从哪里来的。这与我的代码没有任何关系。我只是忽略它--到目前为止一切都很好。

问题是，这意味着每个请求都必须输入令牌，这是一件痛苦的事情。理想情况下，我希望使用内置的swagger接口进行身份验证-根据几篇文章，我应该能够做到这一点；

c.AddSecurityDefinition("Bearer", new ApiKeyScheme()
{ In = "header", Description = "Please insert JWT with Bearer into field", Name = "Authorization", Type = "apiKey" });

这可以很好地工作，我可以添加令牌，只是似乎缺少一个步骤来将令牌添加到每个请求的头部。如果我只是添加auth，那么就会得到下面的头信息，这当然会导致身份验证失败。

为了让请求包含每个后续请求的令牌，我还需要做些什么？

asp.net-core

jwt

最后，我转到了NSwag，所以我不确定最初的问题是什么。Nswag中的解决方案如下；

    services.AddSwaggerDocument(document =>
        {
            document.DocumentName = "CPSwagger";
            document.Title = "My Mobile API";
            document.Version = "v10.3.4";
            document.Description = "An interface for some software.";

            document.DocumentProcessors.Add(
                new SecurityDefinitionAppender("JWT token", new NSwag.OpenApiSecurityScheme
                {
                    Type = NSwag.OpenApiSecuritySchemeType.ApiKey,
                    Name = "Authorization",
                    Description = "Copy 'Bearer ' + valid JWT token into field",
                    In = NSwag.OpenApiSecurityApiKeyLocation.Header
                }));
            document.OperationProcessors.Add(new OperationSecurityScopeProcessor("JWT token"));
        });

如果您在您的方法上指定了过滤器，Swagger将添加authorzation头。如果您在全局范围内需要授权，我猜swagger无法识别它们。

您需要在ConfigureServices中添加一个如下所示的SecurityRequirement：

c.AddSecurityRequirement(new Dictionary<string, IEnumerable<string>>()
{
  { "Bearer", new string[]{ } }
});

如果设置了令牌，这将要求在每个请求中使用发送报头。如果您没有设置标题之前，它将不会发送它，但您仍然会有挂锁标志旁边的api描述。

如果您在代码中定义

c.AddSecurityDefinition("jwt", new ApiKeyScheme()
{ 
   In = "header", Description = "Please insert JWT with Bearer into field", Name = "Authorization", Type = "apiKey" });

然后在.Security中而不是在.Parameters中使用它

operation.Security = new List<IDictionary<string, IEnumerable<string>>> {
            new Dictionary<string, IEnumerable<string>>
            {
                {"jwt", _scopes }
            }

那么一切都应该正常工作：

我做的和你做的一样，但是你应该添加如下内容(对于oauth2或jwt持有者令牌身份验证)：

    public static class ServiceCollectionExtension
{
    private static string XmlCommentsFilePath
    {
        get
        {
            var basePath = PlatformServices.Default.Application.ApplicationBasePath;
            var fileName = Assembly.GetEntryAssembly().GetName().Name + ".xml";
            return Path.Combine(basePath, fileName);
        }
    }

    public static void AddMySwagger(
        this IServiceCollection services,
        ApiVersion defaultApiVersion,
        Func<ApiVersionDescription, Info> info,
        string authority = null,
        Dictionary<string, string> scopes = null)
    {
        services.AddMvcCore().AddVersionedApiExplorer(o => o.GroupNameFormat = "'v'VVV");

        services.AddApiVersioning(o =>
        {
            o.ReportApiVersions = true;
            o.AssumeDefaultVersionWhenUnspecified = true;
            o.DefaultApiVersion = defaultApiVersion;
        });

        services.AddSwaggerGen(
            options =>
            {
                var provider = services.BuildServiceProvider()
                    .GetRequiredService<IApiVersionDescriptionProvider>();

                foreach (var description in provider.ApiVersionDescriptions)
                {
                    if (!description.IsDeprecated)
                        options.SwaggerDoc(description.GroupName, info(description));
                }

                options.OperationFilter<DefaultValues>();

                options.IncludeXmlComments(XmlCommentsFilePath);

                if (!string.IsNullOrEmpty(authority))
                {
                    options.AddSecurityDefinition("jwt", new ApiKeyScheme()
                    {
                        Description = "JWT Authorization header using the Bearer scheme. Example: \"Bearer {token}\"",
                        Name = "Authorization",
                        In = "header",
                        Type = "apiKey"
                    });
                    //options.AddSecurityDefinition("oauth2", new OAuth2Scheme
                    //{
                    //  Flow = "implicit",
                    //  AuthorizationUrl = $"{authority}/connect/authorize",
                    //  Scopes = scopes ?? new Dictionary<string, string>()
                    //});
                    options.OperationFilter<AuthorizeCheckOperationFilter>(scopes?.Select(_ => _.Key).ToList() ?? new List<string>());
                }
            });
    }

    class AuthorizeCheckOperationFilter : IOperationFilter
    {
        private readonly IEnumerable<string> _scopes;

        public AuthorizeCheckOperationFilter(IEnumerable<string> scopes)
        {
            _scopes = scopes;
        }

        public void Apply(Operation operation, OperationFilterContext context)
        {
            var hasAuthorize = context.ApiDescription.ControllerAttributes().OfType<AuthorizeAttribute>().Any() ||
                               context.ApiDescription.ActionAttributes().OfType<AuthorizeAttribute>().Any();

            if (hasAuthorize)
            {
                operation.Responses.Add("401", new Response { Description = "Unauthorized" });
                operation.Responses.Add("403", new Response { Description = "Forbidden" });

                operation.Security = new List<IDictionary<string, IEnumerable<string>>> {
                new Dictionary<string, IEnumerable<string>>
                {
                    //{"oauth2", _scopes},
                    {"jwt", _scopes }
                }
            };
            }
        }
    }
}

用法：

        services.AddMySwagger(
            new ApiVersion(1, 0),
            __description => new Info { Title = $"API v{__description.ApiVersion}", Version = __description.ApiVersion.ToString() },
            Configuration.GetValue<string>("Authentication:Authority"),
            new Dictionary<string, string> { { Configuration.GetValue<string>("Authentication:Scope"), "Partnership API" } }
        );
