  • 在MVC项目中使用 Swagger API文档

    参考文档:

    https://www.cnblogs.com/liaods/p/10101513.html

    https://www.cnblogs.com/zyz-Notes/p/12030281.html

    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 = {

                }
            },
    
            //设置控制器注释
            _setControllerSummary = function () {
                $.ajax({
                    type: "get",
                    async: true,
                    url: $("#input_baseUrl").val(),
                    dataType: "json",

                        $("#resources_container .resource").each(function (i, item) {
                            id = $(item).attr("id");
                            if (id) {
                                controllerName = id.substring(9);
                                strSummary = summaryDict[controllerName];
                                if (strSummary) {
                                    $(item).children(".heading").children(".options").prepend('<li class="controller-summary" title="' + strSummary + '">' + strSummary + '</li>');
                                }
                            }
                        });
                    }
                });
            },
    
            //尝试将英文转换成中文
            _tryTranslate = function () {
                $('[data-sw-translate]').each(function () {
                    $(this).html(_getLangDesc($(this).html()));
                    $(this).val(_getLangDesc($(this).val()));
                    $(this).attr('title', _getLangDesc($(this).attr('title')));
                });
            },
            _getLangDesc = function (word) {
                return _words[$.trim(word)] !== undefined ? _words[$.trim(word)] : word;
            };
    
        return {
            Translator: function () {
                document.title = "API描述文档";
                $('body').append('<style type="text/css">.controller-summary{color:#10a54a !important;word-break:keep-all;white-space:nowrap;overflow:hidden;text-overflow:ellipsis;max-250px;text-align:right;cursor:default;} </style>');
                $("#logo").html("接口描述").attr("href", "/Home/Index");
                //设置控制器描述
                _setControllerSummary();
                _translator2Cn();
            }
        }
    })();
    //执行转换
    SwaggerTranslator.Translator();

    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!
