MVC项目集成swagger

1、创建WebAPI项目解决方案

2、使用nuget引入Swashbuckle包

引入Swashbuckle包后App_Start文件夹下会多出一个SwaggerConfig文件

3、添加接口注释

项目属性->生成，勾选生成xml文档文件（有些太古老的WebSite项目不支持注释功能，因为根本没有生成xml这一个选项）

生成xml文档后在SwaggerConfig文件里加入配置

 var xmlAPI = $@"{AppDomain.CurrentDomain.BaseDirectory}inWebApplication.xml";

 

包含xml注释，在.EnableSwagger里找到c.IncludeXmlComments并传入刚才添加的xml路径，此处是（XMLAPI）

.EnableSwagger(c=>{
　　c.IncludeXmlComments(xmlAPI);
})

在Global.asax文件中注册

 

到此已经可以运行项目并且可以看到注释，在浏览器地址栏输入http://xxx/Swagger回车即可

现在看到的文档界面都是英文的，接下来进行汉化

4、汉化

　　4.1创建js文件，把下面的js代码放入到项目里

///    <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-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();

右击刚才创建的js文件，选择属性，生成操作改为嵌入的资源

在SwaggerConfig文件里加入配置

 .EnableSwaggerUi(c =>{
　//路径规则，项目命名空间.文件夹名称.js文件名称
　　c.InjectJavaScript(thisAssembly, "WebApplication.Scripts.swagger-ui-zh-cn.js");
})

　　4.2、控制器描述和接口文档缓存

 在App_Start目录下创建类文件CachingSwaggerProvider

    public class CachingSwaggerProvider : ISwaggerProvider
    {
        private readonly ISwaggerProvider _swaggerProvider;
        private static ConcurrentDictionary<string, SwaggerDocument> _cache =
            new ConcurrentDictionary<string, SwaggerDocument>();
        private readonly string _xml;

        public CachingSwaggerProvider(ISwaggerProvider swaggerProvider, string xml)
        {
            _swaggerProvider = swaggerProvider;
            _xml = xml;
        }

        public SwaggerDocument GetSwagger(string rootUrl, string apiVersion)
        {
            var cacheKey = string.Format("{0}_{1}", rootUrl, apiVersion);
            SwaggerDocument srcDoc = null;
            //只读取一次
            if (!_cache.TryGetValue(cacheKey, out srcDoc))
            {
                srcDoc = _swaggerProvider.GetSwagger(rootUrl, apiVersion);

                srcDoc.vendorExtensions = new Dictionary<string, object> { { "ControllerDesc", GetControllerDesc() } };
                _cache.TryAdd(cacheKey, srcDoc);
            }
            return srcDoc;
        }

        /// <summary>
        /// 从API文档中读取控制器描述
        /// </summary>
        /// <returns>所有控制器描述</returns>
        public ConcurrentDictionary<string, string> GetControllerDesc()
        {
            string xmlpath = _xml;
            ConcurrentDictionary<string, string> controllerDescDict = new ConcurrentDictionary<string, string>();
            if (File.Exists(xmlpath))
            {
                XmlDocument xmldoc = new XmlDocument();
                xmldoc.Load(xmlpath);
                string type = string.Empty, path = string.Empty, controllerName = string.Empty;

                string[] arrPath;
                int length = -1, cCount = "Controller".Length;
                XmlNode summaryNode = null;
                foreach (XmlNode node in xmldoc.SelectNodes("//member"))
                {
                    type = node.Attributes["name"].Value;
                    if (type.StartsWith("T:"))
                    {
                        //控制器
                        arrPath = type.Split('.');
                        length = arrPath.Length;
                        controllerName = arrPath[length - 1];
                        if (controllerName.EndsWith("Controller"))
                        {
                            //获取控制器注释
                            summaryNode = node.SelectSingleNode("summary");
                            string key = controllerName.Remove(controllerName.Length - cCount, cCount);
                            if (summaryNode != null && !string.IsNullOrEmpty(summaryNode.InnerText) && !controllerDescDict.ContainsKey(key))
                            {
                                controllerDescDict.TryAdd(key, summaryNode.InnerText.Trim());
                            }
                        }
                    }
                }
            }
            return controllerDescDict;
        }
    }

在SwaggerConfig文件里加入配置

.EnableSwagger(c=>{
　　c.CustomProvider((defaultProvider) => new CachingSwaggerProvider(defaultProvider,xmlAPI));
})

　　4.3、action 方法名称相同处理

.EnableSwagger(c=>{
　　c.ResolveConflictingActions(apiDescriptions => apiDescriptions.First());
})

5、一个Controller不支持多个Get/Post请求问题，修改WebApiConfig.cs

打开 App_Start目录下的WebApiConfig文件
