swaggerui在asp.net web api core 中的应用

Swaggerui 可以为我们的webapi提供美观的在线文档，如下图：

实现步骤：

• NuGet Packages  Install-Package Swashbuckle.AspNetCore
• 在startup文件中配置swagger

              // Register the Swagger generator, defining one or more Swagger documents
              services.AddSwaggerGen(c =>
              {
                  c.SwaggerDoc("v1", new Info
                  {
                      Version = "v1",
                      Title = "ToDo API",
                      Description = "A simple example ASP.NET Core Web API",
                      TermsOfService = "None",
                      Contact = new Contact { Name = "Shayne Boyer", Email = "", Url = "https://twitter.com/spboyer" },
                      License = new License { Name = "Use under LICX", Url = "https://example.com/license" }
                  });
  
                  //Set the comments path for the swagger json and ui.
                  var basePath = PlatformServices.Default.Application.ApplicationBasePath;
                  var xmlPath = Path.Combine(basePath, "MyWebApiCore.xml");
                  c.IncludeXmlComments(xmlPath);
              });
          }
  
          // This method gets called by the runtime. Use this method to configure the HTTP request pipeline.
          public void Configure(IApplicationBuilder app, IHostingEnvironment env, ILoggerFactory loggerFactory)
          {
              loggerFactory.AddConsole(Configuration.GetSection("Logging"));
              loggerFactory.AddDebug();
  
              app.UseMvc();
              app.UseSwagger();
              app.UseSwaggerUI(c =>
              {
                  c.SwaggerEndpoint("/swagger/v1/swagger.json", "My API V1");
              });
          }

• XML Comments，点击项目属性=》生成=》XML文档文件打勾，然后在你的action上添加注释

    /// <summary>
          /// Get方法无参数
          /// </summary>
          /// <returns>string[]数组</returns>
          [HttpGet]
          public IEnumerable<string> Get()
          {
              return new string[] { "value1", "value2" };
          }
  
          /// <summary>
          /// 根据id获取
          /// </summary>
          /// <param name="id"></param>
          /// <returns></returns>
          /// <remarks>
          /// Note that the id is an integer.
          /// </remarks>
          [HttpGet("{id}")]
          public string Get(int id)
          {
              return "value";
          }

• 运行项目，输入文档地址http://localhost:58911/swagger/

  你可以选择方法进行在线测试
