本示例使用MVC项目做演示(不推荐,推荐直接用WebAPI),框架版本使用 4.6.2
为了支持WebAPI,我们需要把当前的MVC项目改造一下,右键项目,通过 Nuget添加WebAPI的支持
在 App_Start 文件夹下添加 WebApiConfig 类
1 public class WebApiConfig 2 { 3 public static void Register(HttpConfiguration config) 4 { 5 // Web API 配置和服务 7 // Web API 路由 8 config.MapHttpAttributeRoutes(); 9 10 config.Routes.MapHttpRoute( 11 name: "DefaultApi", 12 routeTemplate: "api/{controller}/{action}/{id}", 13 defaults: new { id = RouteParameter.Optional } 14 ); 17 var jsonFormatter = new JsonMediaTypeFormatter(); 20 //jsonFormatter.SerializerSettings.NullValueHandling = NullValueHandling.Ignore; 23 } 24 }
然后在全局中注册改文件,代码放到第二行,接下来就可以使用了
右键项目安装: Swashbuckle 版本 5.6.0
安装成功之后,在App_Start文件夹下多了一个文件:SwaggerConfig.cs
打开全局视图 _Layout.cshtml,在里边添加一个链接:
<li>@Html.ActionLink("Swagger Help", "", "Swagger", new { area = "" }, null)</li>
直接运行,效果如下:
添加一个测试接口,UserInfoController
1 public class UserInfoController : BaseController 2 { 3 /// <summary> 4 /// GET: 用户信息首页接口 5 /// </summary> 6 /// <remarks> 7 /// 我是备注信息 8 /// </remarks> 9 /// <returns>我是返回信息</returns> 10 [HttpGet] 11 public IHttpActionResult Index() 12 { 13 return Json("Hello World"); 14 } 15 }
如下图所示,接口显示出来了,但都是英文,备注信息也没有显示出来,后边解决
点击按钮: “Try It out”,会返回该接口内容
接下来,我们解决备注不显示的问题,项目右键-->属性,在 生成 选项卡中勾选 xml文档文件选项。
然后打开 SwaggerConfig.cs 类,找到函数: c.IncludeXmlComments(GetXmlCommentsPath()) ,放开该行代码注释
并添加方法:GetXmlCommentsPath()
/// <summary> /// 获取文档路径 /// </summary> /// <returns></returns> static string GetXmlCommentsPath() { return $@"{System.AppDomain.CurrentDomain.BaseDirectory}inSwagger.Mvc.xml"; }
现在注释信息显示出来了,但是其他的地方还是英文
添加汉化支持,添加自定义汉化脚本,右键项目,添加文件夹 Swagger,添加js脚本文件 swagger_lang.js,右键该脚本文件,在属性中的生成操作改为嵌入的资源
复制如下脚本:
///<summary> /// 中文转换 ///</summary> var SwaggerTranslator = (function () { //定时执行检测是否转换成中文,最多执行500次 即500*50/1000=25s var iexcute = 0, //中文语言包 _words = { "Warning: Deprecated": "警告:已过时", "Implementation Notes": "实现备注", "Response Class": "响应类", "Status": "状态", "Parameters": "参数", "Parameter": "参数", "Value": "值", "Description": "描述", "Parameter Type": "参数类型", "Data Type": "数据类型", "Response Messages": "响应消息", "HTTP Status Code": "HTTP状态码", "Reason": "原因", "Response Model": "响应模型", "Request URL": "请求URL", "Response Body": "响应体", "Response Code": "响应码", "Response Headers": "响应头", "Hide Response": "隐藏响应", "Headers": "头", "Try it out!": "试一下!", "Show/Hide": "显示/隐藏", "List Operations": "显示操作", "Expand Operations": "展开操作", "Raw": "原始", "can't parse JSON.

打开 SwaggerConfig.cs 类 ,找到函数:InjectJavaScript,并修改成上边自定义的js文件路径,格式用点分开
c.InjectJavaScript(thisAssembly, "Swagger.Mvc.Swagger.swagger_lang.js");
添加控制器描述和接口文档缓存
1 public class CachingSwaggerProvider : ISwaggerProvider 2 { 3 private static ConcurrentDictionary<string, SwaggerDocument> _cache = 4 new ConcurrentDictionary<string, SwaggerDocument>(); 5 6 private readonly ISwaggerProvider _swaggerProvider; 7 8 public CachingSwaggerProvider(ISwaggerProvider swaggerProvider) 9 { 10 _swaggerProvider = swaggerProvider; 11 } 12 13 public SwaggerDocument GetSwagger(string rootUrl, string apiVersion) 14 { 15 var cacheKey = string.Format("{0}_{1}", rootUrl, apiVersion); 16 SwaggerDocument srcDoc = null; 17 //只读取一次 18 if (!_cache.TryGetValue(cacheKey, out srcDoc)) 19 { 20 srcDoc = _swaggerProvider.GetSwagger(rootUrl, apiVersion); 21 22 srcDoc.vendorExtensions = new Dictionary<string, object> { { "ControllerDesc", GetControllerDesc() } }; 23 _cache.TryAdd(cacheKey, srcDoc); 24 } 25 return srcDoc; 26 } 27 28 /// <summary> 29 /// 从API文档中读取控制器描述 30 /// </summary> 31 /// <returns>所有控制器描述</returns> 32 public static ConcurrentDictionary<string, string> GetControllerDesc() 33 { 34 string xmlpath = string.Format("{0}/bin/Swagger.Mvc.xml", System.AppDomain.CurrentDomain.BaseDirectory); 35 ConcurrentDictionary<string, string> controllerDescDict = new ConcurrentDictionary<string, string>(); 36 if (File.Exists(xmlpath)) 37 { 38 XmlDocument xmldoc = new XmlDocument(); 39 xmldoc.Load(xmlpath); 40 string type = string.Empty, path = string.Empty, controllerName = string.Empty; 41 42 string[] arrPath; 43 int length = -1, cCount = "Controller".Length; 44 XmlNode summaryNode = null; 45 foreach (XmlNode node in xmldoc.SelectNodes("//member")) 46 { 47 type = node.Attributes["name"].Value; 48 if (type.StartsWith("T:")) 49 { 50 //控制器 51 arrPath = type.Split('.'); 52 length = arrPath.Length; 53 controllerName = arrPath[length - 1]; 54 if (controllerName.EndsWith("Controller")) 55 { 56 //获取控制器注释 57 summaryNode = node.SelectSingleNode("summary"); 58 string key = controllerName.Remove(controllerName.Length - cCount, cCount); 59 if (summaryNode != null && !string.IsNullOrEmpty(summaryNode.InnerText) && !controllerDescDict.ContainsKey(key)) 60 { 61 controllerDescDict.TryAdd(key, summaryNode.InnerText.Trim()); 62 } 63 } 64 } 65 } 66 } 67 return controllerDescDict; 68 } 69 70 71 }
在SwaggerConfig.cs 类 中放开注释代码:
c.CustomProvider((defaultProvider) => new CachingSwaggerProvider(defaultProvider));
再次运行程序后,现在变成中的了。
备注内容换行,在相应备注后边加 <br></br>即可出现换行,换行标签要成对出现,否则会报错
最后运行效果如下:
总结:
最后有个问题,就是项目名称中间不能用点来分割,比如: Swagger.Mvc 这样就不行,这样的名字,上边汉化时会找不到路径。所以需要把中间的点去掉,坑啊!
