swagger webapi控制器注释不显示

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");
c.ResolveConflictingActions(apiDescriptions => apiDescriptions.First());
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

 

'use strict';
window.SwaggerTranslator = {
    _words: [],

    translate: function () {
        var $this = this;
        $('[data-sw-translate]').each(function () {
            $(this).html($this._tryTranslate($(this).html()));
            $(this).val($this._tryTranslate($(this).val()));
            $(this).attr('title', $this._tryTranslate($(this).attr('title')));
        });
    },

    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) {
                            $(item).children(".heading").children(".options").first().prepend('<li class="controller-summary" title="' + strSummary + '">' + strSummary + '</li>');
                        }
                    }
                });
            }
        });
    },
    _tryTranslate: function (word) {
        return this._words[$.trim(word)] !== undefined ? this._words[$.trim(word)] : word;
    },

    learn: function (wordsMap) {
        this._words = wordsMap;
    }
};


/* jshint quotmark: double */
window.SwaggerTranslator.learn({
    "Warning: Deprecated": "警告:已过时",
    "Implementation Notes": "实现备注",
    "Response Class": "响应类",
    "Status": "状态",
    "Parameters": "参数",
    "Parameter": "参数",
    "Value": "值",
    "Description": "描述",
    "Parameter Type": "参数类型",
    "Data Type": "数据类型",
    "Response Messages": "响应消息",
    "HTTP Status Code": "HTTP状态码",

    "Response Body": "响应体",
    "Response Code": "响应码",
    "Response Headers": "响应头",
    "Hide Response": "隐藏响应",
    "Headers": "头",
    "Try it out!": "试一下!",
    "Show/Hide": "显示/隐藏",
    "List Operations": "显示操作",
    "Expand Operations": "展开操作",
    "Raw": "原始",
    "can't parse JSON.  Raw result": "无法解析JSON. 原始结果",
    "Model Schema": "模型架构",
    "Model": "模型",
    "apply": "应用",
    "Username": "用户名",
    "Password": "密码",
    "Terms of service": "服务条款",
    "Created by": "创建者",
    "See more at": "查看更多:",
    "Contact the developer": "联系开发者",
    "api version": "api版本",
    "Response Content Type": "响应Content Type",
    "fetching resource": "正在获取资源",
    "fetching resource list": "正在获取资源列表",
    "Explore": "浏览",
    "Show Swagger Petstore Example Apis": "显示 Swagger Petstore 示例 Apis",
    "Can't read from server.  It may not have the appropriate access-control-origin settings.": "无法从服务器读取。可能没有正确设置access-control-origin。",
    "Please specify the protocol for": "请指定协议:",
    "Can't read swagger JSON from": "无法读取swagger JSON于",
    "Finished Loading Resource Information. Rendering Swagger UI": "已加载资源信息。正在渲染Swagger UI",
    "Unable to read api": "无法读取api",
    "from path": "从路径",
    "server returned": "服务器返回"
});
$(function () {
    window.SwaggerTranslator.translate();
    window.SwaggerTranslator.setControllerSummary();
});

 

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"));

doc/{*assetPath}会将swagger的访问地址改为doc/index

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.ResolveConflictingActions(apiDescriptions => apiDescriptions.First()); 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")); } } }
