自动生成 WebApi 在线说明文档。

1.使用Swashbuckle实现

Swashbuckle 是.NET类库,可以将WebAPI所有开放的控制器方法生成对应SwaggerUI的JSON配置。再通过SwaggerUI 显示出来。类库中已经包含SwaggerUI 。所以不需要额外安装。

2.快速开始。前提已有webapi项目

查看webapi项目属性，在【生成】选项卡中勾选X【ML文档文件】。在编译过程中会生成一个注释文件

• 使用NuGet包将Swashbuckle库添加到在webapi项目中

• 引用后，在App_Start文件夹下会生成一个SwaggerConfig.cs配置文件。可以修改配置文件，实现自定义SwaggerUI相关展示行为等。

• 自定义swagger提供类，实现中文展示

 /// <summary>
    /// 自定义swagger的控制器描述
    /// </summary>
    public class SwaggerControllerDescProvider : ISwaggerProvider
    {
        private readonly ISwaggerProvider _swaggerProvider;
        private readonly string _xml;
        ///

        /// xml文档路径
        public SwaggerControllerDescProvider(ISwaggerProvider swaggerProvider, string xml)
        {
            _swaggerProvider = swaggerProvider;
            _xml = xml;
        }

        public SwaggerDocument GetSwagger(string rootUrl, string apiVersion)
        {
            SwaggerDocument srcDoc = null;
            srcDoc = _swaggerProvider.GetSwagger(rootUrl, apiVersion);
            srcDoc.vendorExtensions = new Dictionary<string, object> { { "ControllerDesc", GetControllerDesc() } };
            return srcDoc;
        }

        /// 

        /// 从API文档中读取控制器描述
        ///
        /// 所有控制器描述
        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;
        }

    }

• 　　添加js文件，实现中文展示等。注意：查看js文件属性，将生成操作改为【嵌入的资源】

'use strict';

/**
 * Translator for documentation pages.
 *
 * To enable translation you should include one of language-files in your index.html
 * after <script src='lang/translator.js' type='text/javascript'></script>.
 * For example - <script src='lang/ru.js' type='text/javascript'></script>
 *
 * If you wish to translate some new texsts you should do two things:
 * 1. Add a new phrase pair ("New Phrase": "New Translation") into your language file (for example lang/ru.js). It will be great if you add it in other language files too.
 * 2. Mark that text it templates this way <anyHtmlTag data-sw-translate>New Phrase</anyHtmlTag> or <anyHtmlTag data-sw-translate value='New Phrase'/>.
 * The main thing here is attribute data-sw-translate. Only inner html, title-attribute and value-attribute are going to translate.
 *
