.net framework中webapi使用swagger进行接口文档展示

第一步：在nuget程序包管理中搜索“Swashbuckle”包，然后进行安装（注：如果是.*** core api请安装Sawshbuckle asp***core）。

第二步：打开项目App_Start文件夹，修改SwaggerConfig.cs配置文件

我这里仅仅是修改swagger文档的标题

第三步：创建主项目的xml注释文档：

右键项目→属性→生成→选中下方的 "XML文档文件" 然后保存

如果是其他类库项目，比如实体类库，用于创建接口请求参数实体或返回参数实体项目，需要在swagger文档中展示备注时，可在启动项中添加配置：

c.IncludeXml***ments(Xml***mentsHelper.Xml***mentsPath);

c.IncludeXml***ments(Xml***mentsHelper.ModelXml***mentsPath);

    /// <summary>
    /// 需要展示在swagger文档中实体XML路径
    /// </summary>
    public class Xml***mentsHelper
    {


        /// <summary>
        /// XML注释路径
        /// </summary>
        public static string Xml***mentsPath
        {
            get
            {
                string path = string.Format("{0}/bin/MustWinLotteryWebApi.xml", System.AppDomain.CurrentDomain.BaseDirectory);
                return path;
            }
        }

        /// <summary>
        /// 模型XML注释路径
        /// </summary>
        public static string ModelXml***mentsPath
        {
            get
            {
                string path = string.Format("{0}/bin/MustWinLotteryWebApi.Model.xml", System.AppDomain.CurrentDomain.BaseDirectory);
                return path;
            }
        }
    }

完成以上操作后，可直接启动webapi项目，然后在接口地址后面输入 /swagger   （默认是英文的，如果需要中文显示  还需要做汉化处理）

以下是对swagger文档进行汉化处理方法：

第一步：在nuget程序包管理中搜索“Swagger.***”包和“Swagger.***.UI”，然后进行安装。

第二步：安装完成后，注释掉Swagger***类中的assembly

第三步：创建一个“SwaggerControllerDescProvider”类，用于对swagger文档中的内容进行汉化处理。

    /// <summary>
    /// swagger显示控制器的描述
    /// </summary>
    public class SwaggerControllerDescProvider : ISwaggerProvider
    {
        private readonly ISwaggerProvider _swaggerProvider;
        private static ConcurrentDictionary<string, SwaggerDocument> _cache = new ConcurrentDictionary<string, SwaggerDocument>();
        private readonly string _xml;
        /// <summary>
        /// 
        /// </summary>
        /// <param name="swaggerProvider"></param>
        /// <param name="xml">xml文档路径</param>
        public SwaggerControllerDescProvider(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, ***ount = "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 - ***ount, ***ount);
                            if (summaryNode != null && !string.IsNullOrEmpty(summaryNode.InnerText) && !controllerDescDict.ContainsKey(key))
                            {
                                controllerDescDict.TryAdd(key, summaryNode.InnerText.Trim());
                            }
                        }
                    }
                }
            }
            return controllerDescDict;
        }
    }

第四步：在SwaggerUI文件夹中，创建一个swagger_lang.js的js,用于对swagger进行汉化处理（注：这个文件必须添加，否则汉化将失败）

swagger_lang.js 文件中的js内容如下：

/// <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 = {

            "Show Swagger Petstore Example Apis": "显示 Swagger Petstore 示例 Apis",
            "Can't read from server.  It may not have the appropriate a***ess-control-origin settings.": "无法从服务器读取。可能没有正确设置a***ess-control-origin。",

            "Click to set as parameter value": "点击设置参数",
            "server returned": "服务器返回"
        },

        //定时执行转换
        _translator2*** = function () {
            if ($("#resources_container .resource").length > 0) {
                _tryTranslate();
            }

            if ($("#explore").text() == "Explore" && iexcute < 500) {
                iexcute++;
                setTimeout(_translator2***, 50);
            }
        },

        //设置控制器注释
        _setControllerSummary = function () {
            $.ajax({
                type: "get",
                async: true,
                url: $("#input_baseUrl").val(),
                dataType: "json",
                su***ess: 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) {
                                var option = $(item).children(".heading").children(".options");
                                if ($(option).children(".controller-summary").length > 0) {
                                    $(option).children(".controller-summary").remove();
                                }
                                $(option).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 () {
            $("#logo").html("公司名称").attr("href", "http://www.xx.***");
            $('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>');
            //设置控制器描述
            _setControllerSummary();
            _translator2***();
        },
        translate: function () {
            this.Translator();
        }
    }
})();
//执行转换
SwaggerTranslator.Translator();

这里需要注意，新增的swagger_lang.js文件需要修改文件属性，将文件生成操作修改为“嵌入的资源”。

第五步：将创建的swagger_lang.js在SwaggerConfig文件中进行引用：

c.InjectJavaScript(thisAssembly, "MustWinLotteryWebApi.SwaggerUI.swagger_lang.js");  //引用中文包

以上就是我对“.*** framework中webapi使用swagger进行接口文档展示”的实现方式及汉化方式的整理，希望对各位码友有帮助。
