通过 NuGet 安装 Swashbuckle。下载Swashbuckle 5.6.0。(Swashbuckle 5.6.0 依赖于 Swashbuckle.Core 5.6.0)
安装完成后,App_Start 文件夹下会多出一个 SwaggerConfig.cs 文件。
重新生成并发布 api,打开网页 http://localhost:7001/swagger(这里注意换成你的 host)
网页显示如下:
上图中框出的名称和版本号是可以修改的,打开 SwaggerConfig.cs 文件,找到如下代码:
c.SingleApiVersion("v1", "API.Test");
修改其中的参数,重新发布即可。
swagger 可以读取代码中的注释,并显示在网页上。如此一来,我们只需要在代码中将注释写好,就可以生成一份可供他人阅读的 API 文档了。
swagger 是通过编译时生成的 xml 文件来读取注释的。这个 xml 文件默认是不生成的,所以先要修改配置。
第一步: 右键项目 -> 属性 -> 生成,把 XML 文档文件勾上。
第二步: 添加配置
在 SwaggerConfig.cs 文件中添加配置如下:
GlobalConfiguration.Configuration
.EnableSwagger(c =>
{
c.SingleApiVersion("v1", "测试 API 接口文档");
// 配置 xml 文件路径
c.IncludeXmlComments($@"{System.AppDomain.CurrentDomain.BaseDirectory}\bin\API.Test.xml");
})
注意:发布的时候,XML 文件不会一起发布,需要手动拷到发布目录下。
默认是不会显示控制器注释的,需要自己写。
在 App_Start 中新建类 SwaggerControllerDescProvider,代码如下:
/// /// swagger 显示控制器的描述/// public class SwaggerCacheProvider : ISwaggerProvider
{
private readonly ISwaggerProvider _swaggerProvider;
private static ConcurrentDictionary<string, SwaggerDocument> _cache = new ConcurrentDictionary<string, SwaggerDocument>();
private readonly string _xmlPath;
///
///
///
///
/// xml文档路径
public SwaggerCacheProvider(ISwaggerProvider swaggerProvider, string xmlpath)
{
_swaggerProvider = swaggerProvider;
_xmlPath = xmlpath;
}
public SwaggerDocument GetSwagger(string rootUrl, string apiVersion)
{
var cacheKey = string.Format("{0}_{1}", rootUrl, apiVersion);
//只读取一次
if (!_cache.TryGetValue(cacheKey, out SwaggerDocument srcDoc))
{
srcDoc = _swaggerProvider.GetSwagger(rootUrl, apiVersion);
srcDoc.vendorExtensions = new Dictionary<string, object>
{
{ "ControllerDesc", GetControllerDesc() }
};
_cache.TryAdd(cacheKey, srcDoc);
}
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()
{
ConcurrentDictionary<string, string> controllerDescDict = new ConcurrentDictionary<string, string>();
if (File.Exists(_xmlPath))
{
XmlDocument xmldoc = new XmlDocument();
xmldoc.Load(_xmlPath);
string[] arrPath;
int cCount = "Controller".Length;
foreach (XmlNode node in xmldoc.SelectNodes("//member"))
{
string type = node.Attributes["name"].Value;
if (type.StartsWith("T:"))
{
arrPath = type.Split('.');
string controllerName = arrPath[arrPath.Length - 1];
if (controllerName.EndsWith("Controller")) //控制器
{
//获取控制器注释
XmlNode 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;
}
}
另外,新建 swagger.js 文件并将其设置成 嵌入的资源,这个文件的作用就是显示控制器注释及汉化。js 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 () {
$.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);
strSummary = summaryDict[controllerName];
if (strSummary) {
$(item).children(".heading").children(".options").first().prepend('+ strSummary + '">' + strSummary + '');
}
}
});
}
});
},
_tryTranslate: function (word) {
return this._words[$.trim(word)] !== undefined ? this._words[$.trim(word)] : word;
},
learn: function (wordsMap) {
this._words = wordsMap;
}
};
/* jshint quotmark: double */window.SwaggerTranslator.learn({

在 SwaggerConfig.cs 添加如下配置:
GlobalConfiguration.Configuration
.EnableSwagger(c =>
{
c.CustomProvider((defaultProvider) => new SwaggerCacheProvider(defaultProvider, $@"{System.AppDomain.CurrentDomain.BaseDirectory}\bin\API.Test.xml"));
})
.EnableSwaggerUi(c =>
{
c.InjectJavaScript(System.Reflection.Assembly.GetExecutingAssembly(), "API.Test.swagger.js");
});
