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}\bin\Swagger.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 = {

        //定时执行转换
        _translator2Cn = function () {
            if ($("#resources_container .resource").length > 0) {
                _tryTranslate();
            }

            if ($("#explore").text() == "Explore" && iexcute < 500) {
                iexcute++;
                setTimeout(_translator2Cn, 50);
            }
        },

        //设置控制器注释
        _setControllerSummary = function () {
            $.ajax({
                type: "get",
                async: true,
                url: $("#input_baseUrl").val(),
                dataType: "json",
                success: function (data) {
                    var summaryDict = data.ControllerDesc;
                    var id, controllerName, strSummary;
                    $("#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-width: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!
