c# webapi swagger

playis 2020-02-13

  1. nuget 安装Swashbuckle
  2. 安装完成后会在App_Start中生成SwaggerConfig.cs
    c# webapi swagger

  3. 项目右键属性生成xml文件
    c# webapi swagger
  4. 在SwaggerConfig中的Register中进行配置
//在内部的GlobalConfiguration.Configuration.EnableSwagger中进行配置

c.SingleApiVersion("v1", "API");
var baseDiretory = System.AppDomain.CurrentDomain.BaseDirectory;
var xmlFile = Path.Combine(baseDiretory, "bin\\API.xml");
if (System.IO.File.Exists(xmlFile))
{
    c.IncludeXmlComments(xmlFile);
}
//多个xml文件,或model与项目分离的时候都需要加载另外的xml
var modelFile = Path.Combine(baseDiretory, "bin\\Model.xml");
if (File.Exists(modelFile))
{
    c.IncludeXmlComments(modelFile);
}

//解决同样的接口名 传递不同参数
c.ResolveConflictingActions(apiDescriptions => apiDescriptions.First());
//自定义provider,可以让Controller的注释也显示出来
c.CustomProvider((defaultProvider) => new SwaggerCacheProvider(defaultProvider, xmlFile));

同时添加自定义方法对swagger的分组模式进行调整
调整的方式为扩展类,代码如下

/// <summary>
    /// API描述器扩展
    /// </summary>
    public static class ApiDescriptionExtension
    {
        /// <summary>
        /// 获取控制器名称
        /// </summary>
        /// <param name="description"></param>
        /// <returns></returns>
        public static string GetControllerName(this ApiDescription description)
        {
            string controllerFullName = description.ActionDescriptor.ControllerDescriptor.ControllerType.FullName;
            string controllerName = controllerFullName;

            if (!string.IsNullOrEmpty(controllerFullName))
            {
                int index = controllerFullName.LastIndexOf('.');
                if (index != -1)
                {
                    controllerName = controllerFullName.Substring(index + 1);
                    controllerName = controllerName.Replace("Controller", "");
                }
            }
            return controllerName;
        }
    }

随后添加调用,调用位置还为上面提到的内部的GlobalConfiguration.Configuration.EnableSwagger中进行配置

c.GroupActionsBy(apiDesc => apiDesc.GetControllerName());

最后调整ui部分,使swagger显示控制器的注释并显示中文
首先添加一个provider,如下

/// <summary>
    /// swagger显示控制器的描述
    /// </summary>
    public class SwaggerCacheProvider : 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 SwaggerCacheProvider(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;
        }
    }

在项目根目录添加swagger.js并将生成属性调整为嵌入的资源,代码如下

'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 () {

        try {
            console.log($("#input_baseUrl").val());
            $.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);

                            try {
                                strSummary = summaryDict[controllerName];

                                console.log(summaryDict);

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

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

$(function () {

    window.SwaggerTranslator.setControllerSummary();
});

随后添加调用

在上述的Register方法中寻找EnableSwaggerUi
在内部添加调用

c.InjectJavaScript(Assembly.GetExecutingAssembly(), "API.swagger.js");

此处的API为项目名称
