ASP.NET WebApi使用Swagger做接口文档
作者：互联网
一，什么是Swagger
相信在做接口的,都会被接口文档烦的不行，接口文档没及时更新，前后端不一致等问题，而Swagger就是用来解决这一问题的！Swagger会根据api方法的注释生成相应的文档，让开发人员不必须再去写接口文档！效果图如下
二，如何在ASP.NET WebApi中使用Swagger
首先，创建一个WebApi 程序SwaggerDemo,这里我不再说如何创建WebApi了，相信大部分的朋友都会，不会的，稍加研究一下就会了。
然后，从nuget 管理器上面下载Swagger,搜索Swagger,选择Swashbuckle安装。
安装完成后，我们新创建一个控制器，因为本人懒，就这样直接命名为Default了，
添加相应的接口方法和注释，我们的基本工作就算完成了。
/// <summary>
/// hello
/// </summary>
/// <returns></returns>
[HttpGet]
public string Hello()
{
return "hello ,to go!";
}
/// <summary>
/// 返回输入值
/// </summary>
/// <param name="str">str</param>
/// <returns></returns>
public string GetMess(string str)
{
return "GET:" + str;
}
/// <summary>
/// 返回空
/// </summary>
/// <returns></returns>
[HttpGet]
public string BackNull()
{
return null;
}
三，Swagger相关的配置设置
要想Swagger能正常运行起来，我们还要进行一些配置
1.设置xml生成文档，在项目的属性--生成--输出 选中xml文档文件;
2.添加相关的操作类 SwaggerCacheProvider
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;
}
}
3.添加js汉化文件swagger.js，并属性设置为嵌入式资源
'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;
console.log(summaryDict);
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];
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;
}
};
/* 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",

"from path": "从路径",
"server returned": "服务器返回"
});
$(function () {
window.SwaggerTranslator.translate();
window.SwaggerTranslator.setControllerSummary();
});
4.配置Swagger
在从nuget中下载Swagger的时候，会自动在App_Start中生成SwaggerConfig.cs 文件，这是Swagger的配置文件，我们在文件中添加如下代码
在EnableSwagger中添加
c.IncludeXmlComments(string.Format("{0}/bin/SwaggerDemo.XML", System.AppDomain.CurrentDomain.BaseDirectory));
c.CustomProvider((defaultProvider) => new SwaggerCacheProvider(defaultProvider, string.Format("{0}/bin/SwaggerDemo.XML", System.AppDomain.CurrentDomain.BaseDirectory)));
其中，xml文件为项目生成的文件。
在EnableSwaggerUi中添加
c.InjectJavaScript(System.Reflection.Assembly.GetExecutingAssembly(), "SwaggerDemo.swagger.js");
其中，js文件为我们刚刚添加的js汉化文件
四，浏览效果
我们启动项目，打开浏览器，输入地址 http://IP:端口号/swagger 即可看到如第一张图的效果了！
