Swashbuckle .NET Core 2 中 JWT 承载的授权 [英] Authorization for JWT bearer in Swashbuckle .NET Core 2

问题描述

我使用身份验证服务为我的应用生成的令牌.那里没有问题.现在我已经介绍了 Swashbuckle 来记录我的 API，我可以通过使用此代码在每个请求中发送 JWT 来进行如下身份验证；

I use tokens generated by an authentication service for my app. No problems there. Now I have introduced Swashbuckle to document my API an I can authenticate as follows by sending the JWT with every request using this code;

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 = "[e-mail]", 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"
            });
        }
    }
}

这给了我以下标题 - 正如预期的那样

Which gives me the following header - as expected

虽然，我不确定 Cookie 是从哪里来的.这与我的代码无关.我只是忽略它 - 到目前为止一切都很好.

Although, I am not sure where the Cookie is coming from. That is nothing to do with my code. I just ignore it - so far so good.

问题在于，这意味着每次请求都必须输入令牌，这很痛苦.理想情况下，我想使用内置的 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；

The problem is that this means the token has to be entered with every request which is a pain. Ideally, I would want to authenticate using the inbuilt swagger interface - according to several articles, I should be able to do this;

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

这很好用，我可以添加令牌，我似乎缺少将令牌添加到每个请求的标头的步骤.如果我只是添加身份验证，那么这会给我以下标头，这当然无法通过身份验证.

This works fine, and I can add the token, there just seems to be a step I am missing to add the token to the header of every request. If I just add the auth, then this gives me the following header, which of course fails the authentication.

为了让请求包含每个后续请求的令牌，我还需要做什么?

What else do I need to do in order to get the request to include the token for every subsequent request?

推荐答案

最后我搬到了 NSwag，所以我不确定最初的问题是什么.Nswag中的解决方案如下；

In the end I moved to NSwag so I am not sure what the original issue was. The solution in Nswag is as follows;

    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"));
        });
