c# webapi swagger Area 多级层次分组 添加header参数

1. nuget 安装Swashbuckle

2. 安装完成后会在App_Start中生成SwaggerConfig.cs
   

3. 项目右键属性生成xml文件
   

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
    {
        public static string GetAreaName(this ApiDescription description)
        {
            string controllerFullName = description.ActionDescriptor.ControllerDescriptor.ControllerType.FullName;

            //获取控制器名称
            string controllerName = "";
            int index = controllerFullName.LastIndexOf('.');
            if (index != -1)
            {
                controllerName = controllerFullName.Substring(index + 1);
                controllerName = controllerName.Replace("Controller", "");
            }

            //匹配areaName
            //如果不包含area,则根据控制器名称进行分组
            string areaName = "";
            if (controllerFullName.Contains(".Areas."))
            {
                //获取area索引位置
                index = controllerFullName.IndexOf(".Areas.");
                areaName = controllerFullName.Substring(index + 7);

                //获取area名称,解决多级目录下area名称不正确的问题
                try
                {
                    index = areaName.IndexOf('.');
                    areaName = areaName.Substring(0, index);
                }
                catch (System.Exception)
                {
                }
            }

            if (string.IsNullOrEmpty(areaName))
            {
                //若不是areas下的controller,将路由格式中的{area}去掉
                description.RelativePath = description.RelativePath.Replace("{area}/", "");
                return areaName;
            }
            //根据area分组
            else
            {
                //string relativePath = $"{areaName}.{controllerName}";
                //若是areas下的controller,将路由格式中的{area}替换为真实areaname
                description.RelativePath = description.RelativePath.Replace("{area}", areaName);
                //description.RelativePath = relativePath;

                var findResult = description.ParameterDescriptions.Where(t => t.Name == "area");
                if (findResult != null && findResult.Count() > 0)
                {
                    description.ParameterDescriptions.Remove(findResult.First());
                }
                return areaName;
            }
        }
        /// <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;
        }
    }

如果需要按照area分组(多级层次分组)，则使用下面的代码

string controllerFullName = description.ActionDescriptor.ControllerDescriptor.ControllerType.FullName;

            //获取控制器名称
            string controllerName = "";
            int index = controllerFullName.LastIndexOf('.');
            if (index != -1)
            {
                controllerName = controllerFullName.Substring(index + 1);
                controllerName = controllerName.Replace("Controller", "");
            }

            //匹配areaName
            //如果不包含area,则根据控制器名称进行分组
            string areaName = "";
            if (controllerFullName.Contains(".Areas."))
            {
                //获取area索引位置
                index = controllerFullName.IndexOf(".Areas.");
                areaName = controllerFullName.Substring(index + 7);

                //获取area名称,解决多级目录下area名称不正确的问题
                index = areaName.IndexOf('.');
                areaName = areaName.Substring(0, index);
            }
            //= Regex.Match(controllerFullName, @"Area.([^,]+).C").Groups[1].ToString().Replace(".", "");
            if (string.IsNullOrEmpty(areaName))
            {
                //若不是areas下的controller,将路由格式中的{area}去掉
                description.RelativePath = description.RelativePath.Replace("{area}/", "");
                return controllerName;
            }
            //根据area分组
            else
            {
                //string relativePath = $"{areaName}.{controllerName}";
                //若是areas下的controller,将路由格式中的{area}替换为真实areaname
                description.RelativePath = description.RelativePath.Replace("{area}", areaName);
                //description.RelativePath = relativePath;

                var findResult = description.ParameterDescriptions.Where(t => t.Name == "area");
                if (findResult != null && findResult.Count() > 0)
                {
                    description.ParameterDescriptions.Remove(findResult.First());
                }
                return controllerName;
                //return areaName;
            }

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

//如果需要根据area的名称过滤，可以使用
//c.GroupActionsBy(apiDesc => apiDesc.GetAreaName());
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

添加自定义过滤器，动态添加swagger页面中的输入框
首先定义处理方法

/// <summary>
    /// 添加自定义的头部输入框
    /// </summary>
    public class OptionalHeaderFilter : IOperationFilter
    {
        /// <summary>
        /// 是否包含头部
        /// </summary>
        /// <param name="operation"></param>
        /// <param name="schemaRegistry"></param>
        /// <param name="apiDescription"></param>
        public void Apply(Operation operation, SchemaRegistry schemaRegistry, ApiDescription apiDescription)

        {
            if (operation.parameters == null)
                operation.parameters = new List<Parameter>();

            var actionFilter = apiDescription.ActionDescriptor.GetCustomAttributes<SwaggerTokenFilter>().Any();
            var controllerFilter = apiDescription.ActionDescriptor.ControllerDescriptor.GetCustomAttributes<SwaggerTokenFilter>(true).Any();
            //添加头部信息输入框
            if (actionFilter || controllerFilter)
            {
                //非必填字段可以设置为required=false
                operation.parameters.Add(new Parameter { name = "introID", @in = "header", description = "introID", required = true, type = "string" });
            }

        }
    }

这里使用了SwaggerTokenFilter做检测，可以根据具体使用添加多个过滤器
随后在swaggerConfig中添加
c.OperationFilter();
