如何在 ASP .Net 核心中的 Swagger 中添加基本授权标头

Question

如何在 Asp .Net 核心中的 Swagger 中添加基本授权标头。默认情况下，api 键视为查询字符串，但我需要对其进行自定义，以便将其包含在标题中。

Answer 1

如果您使用的是 Swashbuckle.AspNetCore v5.0.0-rc2，请参见以下内容：

   c.AddSecurityDefinition("Basic", new OpenApiSecurityScheme
            {
                Description = "Basic auth added to authorization header",
                Name = "Authorization",
                In = ParameterLocation.Header,
                Scheme = "basic",
                Type = SecuritySchemeType.Http
            });

            c.AddSecurityRequirement(new OpenApiSecurityRequirement
            {
                {
                    new OpenApiSecurityScheme
                    {
                        Reference = new OpenApiReference { Type = ReferenceType.SecurityScheme, Id = "Basic" }
                    },
                    new List<string>()
                }
            });

经过几个小时的修补我找到了这个解决方案

首先实现 IOperationFilter 如下：

public class AddRequiredHeaderParameter : IOperationFilter
    {
        void IOperationFilter.Apply(Operation operation, OperationFilterContext context)
        {
            var param = new Param();
            param.Name = "authorization";
            param.In = "header";
            param.Description = "JWT Token";
            param.Required = true;
            param.Type = "string";
            if (operation.Parameters == null)
                operation.Parameters = new List<IParameter>();
            operation.Parameters.Add(param);
        }
    }

然后实现IParameter接口

class Param : IParameter
    {

        public string Description { get; set; }

        public Dictionary<string, object> Extensions { get {return new Dictionary<string, object>{{"test", true}};} }

        public string In { get; set; }

        public string Name { get; set; }

        public string Type { get; set; }

        public bool Required { get; set; }
    }

这里非常重要的是 Type 属性，界面不需要它，但它必须存在，因为 swagger-ui 需要它

最后将它连接到你的 swashbuckle 配置

services.ConfigureSwaggerGen(options =>
{
    options.OperationFilter<AddRequiredHeaderParameter>();
    options.SingleApiVersion(new Info
    {
        Version = "v1",
        Title = "Test",
        Description = "Test Service",
        TermsOfService = "None"
    });
    options.DescribeAllEnumsAsStrings();
});
