C# （WebApi）整合 Swagger

SpringBoot-整合Swagger_jboot整合swagger-CSDN博客

C# webapi 也可以整合Swagger

webapi运行其实有个自带的HELP页面

但是如果觉得UI不好看，且没办法显示方法注释等不方便的操作，我们也可以整合Swagger

一、使用NuGet控制台安装Swagger

在菜单中选择工具->NuGet包管理器->程序包管理器控制台 输入指令

Install-Package Swashbuckle

安装成功就已经可以访问页面了

直接运行项目:IP地址:端口号+swagger/ui/index 即可浏览成功。但是会发现页面是英文的且注释无法显示。

二、配置Swagger 显示中文且显示注释

安装完Swagger会在App_Start文件夹下自动生成  SwaggerConfig.cs  更新它

using System.Web.Http;
using WebActivatorEx;
using TPGYWebAPI;
using Swashbuckle.Application;
using TPGYWebAPI.App_Start;
using System.Linq;
using System.Reflection;[assembly: PreApplicationStartMethod(typeof(SwaggerConfig), "Register")]namespace TPGYWebAPI
{
public class SwaggerConfig
{public static void Register(){var thisAssembly = typeof(SwaggerConfig).Assembly;GlobalConfiguration.Configuration.EnableSwagger(c =>{c.SingleApiVersion("v1", "TPGYWebAPI");//添加下述代码   //注意这里的xml文件名要改成你自己的!!!!                     var xmlFile = string.Format("{0}/bin/TPGYWebAPI.XML", System.AppDomain.CurrentDomain.BaseDirectory);if (System.IO.File.Exists(xmlFile)){c.IncludeXmlComments(xmlFile);}c.ResolveConflictingActions(apiDescriptions => apiDescriptions.First());c.CustomProvider((defaultProvider) => new SwaggerControllerDescProvider(defaultProvider, xmlFile));}).EnableSwaggerUi(b => {    //注意这里的路径 项目名要改成你自己的！！！b.InjectJavaScript(Assembly.GetExecutingAssembly(), "TPGYWebAPI.Scripts.SwaggerConfig.js");});}
}
}

并且在该文件夹下创建   SwaggerControllerDescProvider.cs

using Swashbuckle.Swagger;
using System.Collections.Concurrent;
using System.Collections.Generic;
using System.IO;
using System.Linq;
using System.Web;
using System.Xml;namespace TPGYWebAPI.App_Start
{/// <summary>/// Swagger 配置信息/// </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;}/// <summary>/// GetSwagger/// </summary>/// <param name="rootUrl"></param>/// <param name="apiVersion"></param>/// <returns></returns>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;}}
}

同时在Scripts下面新建SwaggerConfig.js 

'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","Reason": "原因","Response Model": "响应模型","Request URL": "请求URL","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.

});
$(function () {window.SwaggerTranslator.translate();window.SwaggerTranslator.setControllerSummary();
});

 并且把文件属性设置为：

同时还需要启用生成xml文档，右击项目文件属性->生成选项卡（勾选XML文件）。保存后，重新生成。如下图所示
