swagger是webapi文档描述及调试工具,要在asp.net mvc中使用swagger,需要安装Swashbuckle.Core这个包,安装好后会在app_start中生成SwaggerConfig.cs文件,修改Register方法在文件中指定webapi项目生成的xml文件所在路径,详细配置请参考

https://github.com/domaindrivendev/Swashbuckle

using System.Web.Http;
using WebActivatorEx;
using Nop.Web;
using Swashbuckle.Application;
using System.Linq;
using System.Reflection;
using Nop.Web.App_Start;
using System.Xml.Linq;
using System.Xml.XPath;

[assembly: PreApplicationStartMethod(typeof(SwaggerConfig), "Register")]

namespace Nop.Web
{
    public class SwaggerConfig
    {
        public static void Register()
        {
            var xmlFile = string.Format("{0}/Plugins/Misc.Client.WebApi/Nop.Plugin.Misc.Client.WebApi.XML", System.AppDomain.CurrentDomain.BaseDirectory);
            GlobalConfiguration.Configuration.EnableSwagger(c =>
            {
                c.SingleApiVersion("v1", "优里可webapi");
                if (System.IO.File.Exists(xmlFile)) { c.IncludeXmlComments(xmlFile); }
            });
        }
    }
}

 

按上述设置后,可以显示action上的注释,输出输出实体的注释等,看起是不是很爽。

网上有很多文章讲如何汉化,如何结合oauth2.0认证调试接口,但似乎没有人注意到控制器上的注释不会显示(下图红框中的注释是改造以后才有的)

要达到上述效果,具体步骤如下:

1.定义一个provider实现ISwaggerProvider接口

using Swashbuckle.Swagger;
using System;
using System.Collections.Concurrent;
using System.Collections.Generic;
using System.IO;
using System.Linq;
using System.Web;
using System.Xml;

namespace Nop.Web.App_Start
{
    /// <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, 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;
        }
    }
}

 

2.定义一个JS文件,做成嵌入资源,这个js文件的功能主要有两个,一个是汉化,另一个就是在界面上显示控制器的描述文字

/// 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

        //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();

 

3.修改App_Start中的SwaggerConfig.cs文件,主要代码有两行

c.CustomProvider((defaultProvider) => new SwaggerControllerDescProvider(defaultProvider,xmlFile));

.EnableSwaggerUi("doc/{*assetPath}", b => b.InjectJavaScript(Assembly.GetExecutingAssembly(), "Nop.Web.Scripts.Swagger-Custom.js"));

注意:Nop.Web.Scripts.Swagger-Custom.js 这是我们在第二步中定义的资源文件,资源文件名的命名规则如下:文件所在项目的命名空间.文件径路.文件名

最终代码如下:

using System.Web.Http;
using WebActivatorEx;
using Nop.Web;
using Swashbuckle.Application;
using System.Linq;
using System.Reflection;
using Nop.Web.App_Start;
using System.Xml.Linq;
using System.Xml.XPath;

[assembly: PreApplicationStartMethod(typeof(SwaggerConfig), "Register")]

namespace Nop.Web
{
    public class SwaggerConfig
    {
        public static void Register()
        {
            var xmlFile = string.Format("{0}/Plugins/Misc.Client.WebApi/Nop.Plugin.Misc.Client.WebApi.XML", System.AppDomain.CurrentDomain.BaseDirectory);
            GlobalConfiguration.Configuration.EnableSwagger(c =>
            {
                c.SingleApiVersion("v1", "优里可webapi");
                if (System.IO.File.Exists(xmlFile)) { c.IncludeXmlComments(xmlFile); }
                c.CustomProvider((defaultProvider) => new SwaggerControllerDescProvider(defaultProvider,xmlFile));
            })
           //修改访问地址为doc/index
           //注入自定义的js文件
           .EnableSwaggerUi("doc/{*assetPath}", b => b.InjectJavaScript(Assembly.GetExecutingAssembly(), "Nop.Web.Scripts.Swagger-Custom.js"));
        }
    }
}
