webapi文档描述Swagger使用

      1.创建webapi项目解决方案

　　2.引用swagger nuget包

3.项目属性生成xml.

4.为了控制器和action 都有注释，我们创建一个Swagger-Custom.js 和SwaggerControllerDescProvider.cs 文件

            _translator2Cn();
        }
    }
    })();
//执行转换
SwaggerTranslator.Translator();

 

5.打开 SwaggerConfig文件，注入XML.等描述

 public class SwaggerConfig
    {
        public static void Register()
        {
            var thisAssembly = typeof(SwaggerConfig).Assembly;

            GlobalConfiguration.Configuration
                .EnableSwagger(c =>
                    {
                        
                        c.SingleApiVersion("v1", "SwaggerDemo"); 

                        c.IncludeXmlComments(GetXmlCommentsPath());//显示action注释
                        //显示控制器注释
                      c.CustomProvider((defaultProvider) => new SwaggerControllerDescProvider(defaultProvider, GetXmlCommentsPath())); 
                       
                    })
                .EnableSwaggerUi("doc/{*assetPath}", b => b.InjectJavaScript(Assembly.GetExecutingAssembly(), "SwaggerDemo.Scripts.Swagger-Custom.js"));//注入自定义的js文件
        }
        private static string GetXmlCommentsPath()
        {
            return System.String.Format(@"{0}binSwaggerDemo.XML", System.AppDomain.CurrentDomain.BaseDirectory);
        }
    }

 6.生成运行报错时：

需要在配置文件设置指定版本7

<runtime>
		<assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
    
        <dependentAssembly>
          <assemblyIdentity name="Newtonsoft.Json" culture="neutral" publicKeyToken="30ad4fe6b2a6aeed" />
          <bindingRedirect oldVersion="0.0.0.0-7.0.0.0" newVersion="7.0.0.0" />
        </dependentAssembly>
       	</runtime>
