C# Swagger 生成接口文档

一直听说Swagger是做Web API文档的好工具,这次手里暂时没什么事,类体验下它的强大之处。下面是使用Swashbuckle.net 给asp.net web API添加文档的简要步骤。

项目引入Swagger

Swashbuckle是Swagger在dotnet环境中的实现,在ASP.net项目中加入后即可支持Swagger/UI。5.X版本支持ASP.net, 6.X(beta)版本支持ASP.net Core. 目前项目使用ASP.net for IIS,所以使用了5.6的版本。 关于selfhost和Owin Swashbuckle 的readme有很清楚的描述,可以去查看源码

使用nuget加入Swashbuckle的引用

 

安装好以后,在App_Start目录下,会有一个SwaggerConfig.cs文件,SwaggerConfig类通过[assembly: PreApplicationStartMethod(typeof(SwaggerConfig), "Register")]启动时运行。

nuget添加完引用,无须任何配置,编译后,访问 http://localhost:52079/swagger(这里按照自己的项目启动端口更改) 即可看到所有API的文档说明。界面如图所示:

 

SwaggerConfig简单介绍

SwaggerConfig.cs文件会自动添加到项目的App_Start目录下,代码本身包含大量注释掉的代码,清除后,代码如下:

 

相关工程需要生成XML文档

 

在SwaggerConfig 的Register方法的EnableSwagger匿名函数中加上对应的XML文件,修改如下: 

public class SwaggerConfig
    {
        public static void Register()
        {
            var thisAssembly = typeof(SwaggerConfig).Assembly;
            //获取项目文件路径
            var baseDirectory = System.Web.HttpContext.Current.Server.MapPath("~/App_Data");
            var commentsFileName = Assembly.GetExecutingAssembly().GetName().Name + ".XML";
            var commentsFile = Path.Combine(baseDirectory, commentsFileName);

            GlobalConfiguration.Configuration
                .EnableSwagger(c =>
                    {
                        //用于启用和设置Swagger的配置信息。
                        c.SingleApiVersion("v1", "APIUI");
                        //单个xml文件注释读取
                        c.IncludeXmlComments(commentsFile);
                        //多个xml文件注释读取 使用多个时注释单个
                        //DirectoryInfo dirct = new DirectoryInfo(baseDirectory);
                        //foreach (var item in dirct.GetFiles())
                        //{
                        //    if (item.Name.Contains(".xml"))
                        //    {
                        //        var name = baseDirectory + @"\" + item.Name;
                        //        c.IncludeXmlComments(name);
                        //    }
                        //}
                    })
                .EnableSwaggerUi(c =>
                    {
                        //用于启用UI界面。

                    });
        }
    }

 

上述代码把api工程的XML注释加入到Swagger中。一般我们会把viewmodel或者其他类型定义在不同的工程中,通过下面的代码可以继续加入其它xml注释文件。(对应功能需要启用XML文档文件生成)

注:如果System.Web.HttpContext.Current.Server.MapPath获取项目路径报错的话改用下面这句代码

 var baseDirectory = string.Format("{0}App_Data", System.Web.HttpRuntime.AppDomainAppPath);

汉化 SwaggerUI 

新增js,内容如下

'use strict';  
  
/** 
 * Translator for documentation pages. 
 * 
 * To enable translation you should include one of language-files in your index.html 
 * after <script src='lang/translator.js' type='text/javascript'></script>. 
 * For example - <script src='lang/ru.js' type='text/javascript'></script> 
 * 
 * If you wish to translate some new texsts you should do two things: 
 * 1. Add a new phrase pair ("New Phrase": "New Translation") into your language file (for example lang/ru.js). It will be great if you add it in other language files too. 
 * 2. Mark that text it templates this way <anyHtmlTag data-sw-translate>New Phrase</anyHtmlTag> or <anyHtmlTag data-sw-translate value='New Phrase'/>. 
 * The main thing here is attribute data-sw-translate. Only inner html, title-attribute and value-attribute are going to translate. 
 * 
 */  
window.SwaggerTranslator = {  
    _words: [],  
  
    translate: function () {  
        var $this = this;  
        $('[data-sw-translate]').each(function () {  
            $(this).html($this._tryTranslate($(this).html()));  
            $(this).val($this._tryTranslate($(this).val()));  
            $(this).attr('title', $this._tryTranslate($(this).attr('title')));  
        });  
    },  
  
    _tryTranslate: function (word) {  
        return this._words[$.trim(word)] !== undefined ? this._words[$.trim(word)] : word;  
    },  
  
    learn: function (wordsMap) {  
        this._words = wordsMap;  
    }  
};

View Code

注:右键点击该js文件修改属性为嵌入的资源

修改 SwaggerConfig文件:修改如下

 public static void Register()
        {
            var thisAssembly = typeof(SwaggerConfig).Assembly;
            //获取项目文件路径
            var baseDirectory = AppDomain.CurrentDomain.BaseDirectory + @"\App_Data\";
            var commentsFileName = Assembly.GetExecutingAssembly().GetName().Name + ".XML";

            var commentsFile = Path.Combine(baseDirectory, commentsFileName);

            GlobalConfiguration.Configuration
                .EnableSwagger(c =>
                    {
                        //用于启用和设置Swagger的配置信息。
                        c.SingleApiVersion("v1", "APIUI");
                        //获取项目指定路径下xml文件
                        c.IncludeXmlComments(commentsFile);
                    })
                .EnableSwaggerUi(c =>
                    {
                        //用于启用UI界面上的东西。
                        //加载汉化的js文件,注意 swagger.js文件属性必须设置为“嵌入的资源”。 APIUI.Scripts.swagger.js依次是:项目名称->文件夹->js文件名 
                        c.InjectJavaScript(Assembly.GetExecutingAssembly(), "APIUI.Scripts.swagger.js");
                    });
        }

 效果如下:

 在API中显示返回的实体类模型跟注释

在方法上加入特性SwaggerResponse,这里的model是实体类

[SwaggerResponse(HttpStatusCode.OK, Type = typeof(Model))]

效果如下:
