1、前言
为什么我们要隐藏部分接口？
因为我们在用swagger代替接口的时候，难免有些接口会直观的暴露出来，比如我们结合Consul一起使用的时候，会将健康检查接口以及报警通知接口暴露出来，这些接口有时候会出于方便考虑，没有进行加密，这个时候我们就需要把接口隐藏起来，只有内部的开发者知道。
为什么要分组？
通常当我们写前后端分离的项目的时候，难免会遇到编写很多接口供前端页面进行调用，当接口达到几百个的时候就需要区分哪些是框架接口，哪些是业务接口，这时候给swaggerUI的接口分组是个不错的选择。

swagger的基本使用这里将不再赘述，可以阅读微软官方文档，即可基本使用
2、swaggerUI中加入授权请求
-
新建
HttpHeaderOperationFilter
操作过滤器，继承
Swashbuckle.AspNetCore.SwaggerGen.IOperationFilter
接口，实现
Apply
方法
/// <summary>
/// swagger请求头
/// </summary>
public class HttpHeaderOperationFilter : IOperationFilter
{
public void Apply(Operation operation, OperationFilterContext context)
{
#region 新方法
if (operation.Parameters == null)
{
operation.Parameters = new List<IParameter>();
}
if (context.ApiDescription.TryGetMethodInfo(out MethodInfo methodInfo))
{
if (!methodInfo.CustomAttributes.Any(t => t.AttributeType == typeof(AllowAnonymousAttribute))
&&!(methodInfo.ReflectedType.CustomAttributes.Any(t => t.AttributeType == typeof(AuthorizeAttribute))))
{
operation.Parameters.Add(new NonBodyParameter
{
Name = "Authorization",
In = "header",
Type = "string",
Required = true,
Description = "请输入Token，格式为bearer XXX"
});
}
}
#endregion
#region 已过时
//if (operation.Parameters == null)
//{
// operation.Parameters = new List<IParameter>();
//}
//var actionAttrs = context.ApiDescription.ActionAttributes().ToList();
//var isAuthorized = actionAttrs.Any(a => a.GetType() == typeof(AuthorizeAttribute));
//if (isAuthorized == false)
//{
// var controllerAttrs = context.ApiDescription.ControllerAttributes();
// isAuthorized = controllerAttrs.Any(a => a.GetType() == typeof(AuthorizeAttribute));
//}
//var isAllowAnonymous = actionAttrs.Any(a => a.GetType() == typeof(AllowAnonymousAttribute));
//if (isAuthorized && isAllowAnonymous == false)
//{
// operation.Parameters.Add(new NonBodyParameter
// {
// Name = "Authorization",
// In = "header",
// Type = "string",
// Required = true,
// Description = "请输入Token，格式为bearer XXX"
// });
//}
#endregion
}
}
-
然后修改
Startup.cs
中的
ConfigureServices
方法，添加我们自定义的
HttpHeaderOperationFilter
过滤器
public IServiceProvider ConfigureServices(IServiceCollection services)
{
...
services.AddSwaggerGen(c =>
{
...
c.OperationFilter<HttpHeaderOperationFilter>();
});
...
}
这时候我们再访问swaggerUI就可以输入Token了

3、API分组
-
修改
Startup.cs
中的
ConfigureServices
方法，添加多个swagger文档
public IServiceProvider ConfigureServices(IServiceCollection services)
{
...
services.AddSwaggerGen(c =>
{
c.SwaggerDoc("v1", new Info
{
Version = "v1",
Title = "接口文档",
Description = "接口文档-基础",
TermsOfService = "",
Contact = new Contact
{
Name = "XXX1111",
Email = "XXX1111@qq.com",
Url = ""
}
});
c.SwaggerDoc("v2", new Info
{
Version = "v2",
Title = "接口文档",
Description = "接口文档-基础",
TermsOfService = "",
Contact = new Contact
{
Name = "XXX2222",
Email = "XXX2222@qq.com",
Url = ""
}
});
//反射注入全部程序集说明
GetAllAssemblies().Where(t => t.CodeBase.EndsWith("Controller.dll")).ToList().ForEach(assembly =>
{
c.IncludeXmlComments(assembly.CodeBase.Replace(".dll", ".xml"));
});
c.OperationFilter<HttpHeaderOperationFilter>();
//c.DocumentFilter<HiddenApiFilter>();
});
...
}
-
修改
Startup.cs
中的
Configure
方法，加入
public void Configure(IApplicationBuilder app, ILoggerFactory loggerFactory)
{
...
app.UseSwagger();
app.UseSwaggerUI(c =>
{
c.SwaggerEndpoint("/swagger/v2/swagger.json", "接口文档-基础");//业务接口文档首先显示
c.SwaggerEndpoint("/swagger/v1/swagger.json", "接口文档-业务");//基础接口文档放后面后显示
c.RoutePrefix = string.Empty;//设置后直接输入IP就可以进入接口文档
});
...
}
-
然后还要在我们的控制器上面标注swagger文档的版本
img
这时候我们就可以将接口文档进行分组显示了

4、API隐藏
-
创建自定义隐藏特性
HiddenApiAttribute.cs
/// <summary> /// 隐藏swagger接口特性标识 /// </summary> [AttributeUsage(AttributeTargets.Method | AttributeTargets.Class)] public class HiddenApiAttribute:System.Attribute { }
-
创建API隐藏过滤器
HiddenApiFilter
继承
Swashbuckle.AspNetCore.SwaggerGen.IDocumentFilter
接口，实现
Apply
方法
/// <summary>
/// 自定义Swagger隐藏过滤器
/// </summary>
public class HiddenApiFilter : IDocumentFilter
{
public void Apply(SwaggerDocument swaggerDoc, DocumentFilterContext context)
{
foreach (ApiDescription apiDescription in context.ApiDescriptions)
{
if (apiDescription.TryGetMethodInfo(out MethodInfo method))
{
if (method.ReflectedType.CustomAttributes.Any(t=>t.AttributeType==typeof(HiddenApiAttribute))
|| method.CustomAttributes.Any(t => t.AttributeType == typeof(HiddenApiAttribute)))
{
string key = "/" + apiDescription.RelativePath;
if (key.Contains("?"))
{
int idx = key.IndexOf("?", System.StringComparison.Ordinal);
key = key.Substring(0, idx);
}
swaggerDoc.Paths.Remove(key);
}
}
}
}
}
-
在
Startup.cs
中使用
HiddenApiFilter
public IServiceProvider ConfigureServices(IServiceCollection services)
{
...
services.AddSwaggerGen(c =>
{
c.SwaggerDoc("v1", new Info
{
Version = "v1",
Title = "接口文档",
Description = "接口文档-基础",
TermsOfService = "",
Contact = new Contact
{
Name = "XXX1111",
Email = "XXX1111@qq.com",
Url = ""
}
});
c.SwaggerDoc("v2", new Info
{
Version = "v2",
Title = "接口文档",
Description = "接口文档-基础",
TermsOfService = "",
Contact = new Contact
{
Name = "XXX2222",
Email = "XXX2222@qq.com",
Url = ""
}
});
//反射注入全部程序集说明
GetAllAssemblies().Where(t => t.CodeBase.EndsWith("Controller.dll")
&& !t.CodeBase.Contains("Common.Controller.dll")).ToList().ForEach(assembly =>
{
c.IncludeXmlComments(assembly.CodeBase.Replace(".dll", ".xml"));
});
c.OperationFilter<HttpHeaderOperationFilter>();
c.DocumentFilter<HiddenApiFilter>();
});
...
}

示例：
我这里提供了Consul的心跳检车接口
但是在接口文档中并没有显示出来
