Swagger使用
1、创建webapi项目
2、引用swagger nuget包
Swashbuckle

3、添加接口注释
由于默认情况下是不显示注释的,需要收到添加
项目属性-->生成-->XML 文档文件,最后重新生成解决方案,bin文件夹里就多一个SwaggerDemo.xml文件
image.png
修改App_Start里的SwaggerConfig.cs文件
添加xml解析路径(默认是有的,只是注释掉了)
//c.IncludeXmlComments(GetXmlCommentsPath());
//设置接口描述xml路径地址
c.IncludeXmlComments(string.Format("{0}/bin/SwaggerDemo.xml", System.AppDomain.CurrentDomain.BaseDirectory));

4、汉化问题
经过上面的操作,已经完成了所需功能。但是还有几点问题需要完善
1.界面的说明都是英文的需要进行汉化
2.控制器没有描述
汉化步骤
在SwaggerConfig.cs文件里配置
.EnableSwaggerUi(c =>{
//c.InjectJavaScript(thisAssembly, "Swashbuckle.Dummy.SwaggerExtensions.testScript1.js")
});
这段代码的作用是向页面输出引用Swashbuckle.Dummy.SwaggerExtensions.testScript1.js文件,或许会疑问js文件路径为什么这么奇怪。那是因为Swagger将资源文件都嵌入到dll中了,我们常用的资源文件都是以内容的方式放在项目中的,我们也可以以嵌入的资源方式引入到项目中.
这里需要我们自己添加中文语言包,如下配置
//c.InjectJavaScript(thisAssembly, "Swashbuckle.Dummy.SwaggerExtensions.testScript1.js");
//路径规则,项目命名空间.文件夹名称.js文件名称
c.InjectJavaScript(thisAssembly, "SwaggerDemo.Scripts.swaggerui.swagger_lang.js");

这里注意的是生成操作这里必须是嵌入的资源
右击swagger_lang.js文件——属性——生成操作选择(嵌入的资源)
image.png
汉化swagger_lang.js代码如下
/// <summary>
/// 中文转换
/// </summary>
var SwaggerTranslator = (function () {
//定时执行检测是否转换成中文,最多执行500次 即500*50/1000=25s
var iexcute = 0,
//中文语言包

控制器描述和接口文档缓存
新建一个CachingSwaggerProvider.cs类
image.png
CachingSwaggerProvider 类代码如下
public class CachingSwaggerProvider : ISwaggerProvider
{
private static ConcurrentDictionary<string, SwaggerDocument> _cache =
new ConcurrentDictionary<string, SwaggerDocument>();
private readonly ISwaggerProvider _swaggerProvider;
public CachingSwaggerProvider(ISwaggerProvider swaggerProvider)
{
_swaggerProvider = swaggerProvider;
}
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 static ConcurrentDictionary<string, string> GetControllerDesc()
{
string xmlpath = string.Format("{0}/bin/SwaggerDemo.XML", System.AppDomain.CurrentDomain.BaseDirectory);
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SwaggerConfig.cs 类中打开
c.CustomProvider((defaultProvider) => new CachingSwaggerProvider(defaultProvider));

接下来运行看下效果
运行路径:https://localhost:44338/swagger
下面是我自己写的一个接口方法,现在运行会有一个问题,下面会有说明
这就是运行的效果,这里的注释也有了
image.png
有个一问题就是接口里没有显示出来Action,只显示了Controller
image.png解决方法:
发现swashbuckle 是根据我们在路由配置WebApiConfig中的模版来生成的。如,默认的配置代码为:
public static void Register(HttpConfiguration config)
{
// Web API 配置和服务
// Web API 路由
config.MapHttpAttributeRoutes();
config.Routes.MapHttpRoute(
name: "DefaultApi",
routeTemplate: "api/{controller}/{id}",
defaults: new { id = RouteParameter.Optional }
);
}
要在swagger文档中显示接口的方法名,只需修改路由模版就可以了。将id改为action即可,修改后的代码如下:
public static void Register(HttpConfiguration config)
{
// Web API 配置和服务
// Web API 路由
config.MapHttpAttributeRoutes();
config.Routes.MapHttpRoute(
name: "DefaultApi",
routeTemplate: "api/{controller}/{action}",
defaults: new { id = RouteParameter.Optional }
);
}

再运行看下效果:Action显示出来了
