很久不来写blog了，换了新工作后很累，很忙。每天常态化加班到21点，偶尔还会到凌晨，加班很累，但这段时间，也确实学到了不少知识，今天这篇文章和大家分享一下：Asp.Net Core中使用Swagger，你不得不踩的坑.
这篇文章着重讲几点：
- swagger 跨层注释问题
- swagger Get请求传多个参数的问题
- swagger Enum 注释问题
- swagger api文档版本控制
第一步：搭建一个webapi项目或者mvc项目，引入swagger nuget
我创建项目，习惯性的先创建一个解决方案，取名为TB.AspNetCore.Swagger
接着会在解决方案上新建项目，取名TB.AspNetCore.Swagger.SApi，然后选择webapi,https最好去掉，加上后提示你要证书什么的，还会提示你网站不安全，我们做测试，没必要勾选
为了本项目问题的说明，我们会继续在常见三个类库项目TB.AspNetCore.Swagger.Data 放数据库实体，TB.AspNetCore.Swagger.Model 放模型-ViewModel，TB.AspNetCore.Swagger.Enum 放枚举类型
删除项目默认生成的class和controller，在api项目上引入swagger的nuget包，搜索：Swashbuckle.AspNetCore，这个包就在持续更新速度很快，已经到了3.0
第二部：引入版本控制nuget，添加关键性配置代码
这两个包是做版本控制管理的，如果不需要可以不添加，这里我做演示就添加上，额外再引入一个包Microsoft.Extensions.PlatformAbstractions，这个包是获取一些系统配置路径变量的包，这个包实在鸡肋,没有注释。。添加部分关键代码在configuration和configurationservice，代码如下：
services.AddSwaggerGen( ???????????????options => ???????????????{ ???????????????????// resolve the IApiVersionDescriptionProvider service ???????????????????// note: that we have to build a temporary service provider here because one has not been created yet ???????????????????var provider = services.BuildServiceProvider().GetRequiredService<IApiVersionDescriptionProvider>(); ???????????????????// add a swagger document for each discovered API version ???????????????????// note: you might choose to skip or document deprecated API versions differently ???????????????????foreach (var description in provider.ApiVersionDescriptions) ???????????????????{ ???????????????????????options.SwaggerDoc(description.GroupName, CreateInfoForApiVersion(description)); ???????????????????} ???????????????????// add a custom operation filter which sets default values ???????????????????options.OperationFilter<SwaggerDefaultValues>(); ???????????????????// ???????????????????// integrate xml comments ???????????????????options.IncludeXmlComments(XmlCommentsFilePath); ???????????????????options.IncludeXmlComments(XmlModelsFilePath); ???????????????});public void Configure(IApplicationBuilder app, IHostingEnvironment env, IApiVersionDescriptionProvider provider) ???????{ ???????????if (env.IsDevelopment()) ???????????{ ???????????????app.UseDeveloperExceptionPage(); ???????????} ???????????app.UseMvc(); ???????????//Swagger ???????????app.UseSwagger(); ???????????app.UseSwaggerUI( ???????????????options => ???????????????{ ???????????????????foreach (var description in provider.ApiVersionDescriptions) ???????????????????{ ???????????????????????options.SwaggerEndpoint($"/swagger/{description.GroupName}/swagger.json", description.GroupName.ToUpperInvariant()); ???????????????????} ???????????????}); ???????}第三部：新建控制器，测试我们的项目
我做了一个订单查询控制器，一个提交订单，一个查询订单，查询订单为get请求多参数，提交订单为post请求，其中的备注设计到枚举类型的如何加载
代码如下：
namespace TB.AspNetCore.Swagger.SApi.Controllers{ ???[Produces("application/json")] ???[ApiVersion("1.0", Deprecated = false)] ???[Route("api/v{api-version:apiVersion}/[controller]/[action]")] ???[ApiController] ???public class OrderController : ControllerBase ???{ ???????/// <summary> ???????/// 查询订单 ???????/// </summary> ???????/// <param name="orderCode">订单号</param> ???????/// <param name="orderName">订单名称</param> ???????/// <returns></returns> ???????[HttpGet("{orderCode}/{orderName}")] ???????public OrderModel QueryOrder(string orderCode, string orderName) ???????{ ???????????OrderModel model = new OrderModel ???????????{ ???????????????OrderCode = orderCode ???????????}; ???????????return model; ???????} ???????/// <summary> ???????/// 提交订单 ???????/// </summary> ???????/// <param name="model"></param> ???????/// <returns></returns> ???????[HttpPost] ???????public OrderModel SubOrder([FromBody]OrderModel model) ???????{ ???????????return model; ???????} ???} ???public class OrderModel ???{ ???????/// <summary> ???????/// 订单号 ???????/// </summary> ???????public string OrderCode { get; set; } ???????/// <summary> ???????/// 订单金额 ???????/// </summary> ???????public decimal OrderAmount { get; set; } ???????/// <summary> ???????/// 订单类型 ???????/// <Remark> ???????/// 0 商家入驻 ???????/// 1 线下交易 ???????/// </Remark> ???????/// </summary> ???????public OrderTypeInfo OrderType { get; set; } ???} ???/// <summary> ???/// ????/// </summary> ???public enum OrderTypeInfo ???{ ???????/// <summary> ???????/// 商家入驻 ???????/// </summary> ???????[Description("商家入驻")] ???????StoreEntry = 0, ???????/// <summary> ???????/// 线下交易 ???????/// </summary> ???????[Description("线下交易")] ???????StoreTrade = 1, ???}}效果图如下：**我把model和enum写到一个文件里，如果分别跨层写的话，也没有什么问题，只需要在startp里配置一下，由于时间关系，源码我上传到我都github，就不再细分了
