Swashbuckle.AspNetCore3.0的二次封装与使用

关于 Swashbuckle.AspNetCore3.0

一个使用 ASP.NET Core 构建的 API 的 Swagger 工具。直接从您的路由,控制器和模型生成漂亮的 API 文档,包括用于探索和测试操作的 UI。

之前写过一篇Swashbuckle.AspNetCore-v1.10 的使用,现在 Swashbuckle.AspNetCore 已经升级到 3.0 了,正好开新坑(博客重构)重新封装了下,将所有相关的一些东西抽取到单独的类库中,尽可能的避免和项目耦合,使其能够在其他项目也能够快速使用。

封装代码

待博客重构完成再将完整代码开源,参考下面步骤可自行封装

1. 新建类库并添加引用

我引用的版本如下

    <PackageReference Include="Microsoft.AspNetCore.Http.Abstractions" Version="2.1.1" /> <PackageReference Include="Microsoft.AspNetCore.Mvc" Version="2.1.1" /> <PackageReference Include="Swashbuckle.AspNetCore" Version="3.0.0" />

2. 构建参数模型 CustsomSwaggerOptions.cs

    public class CustsomSwaggerOptions
    {
        ///  /// 项目名称 ///  public string ProjectName { get; set; } = "My API"; ///  /// 接口文档显示版本 ///  public string[] ApiVersions { get; set; } ///  /// 接口文档访问路由前缀 ///  public string RoutePrefix { get; set; } = "swagger"; ///  /// 使用自定义首页 ///  public bool UseCustomIndex { get; set; } ///  /// UseSwagger Hook ///  public Action UseSwaggerAction { get; set; } ///  /// UseSwaggerUI Hook ///  public Action UseSwaggerUIAction { get; set; } ///  /// AddSwaggerGen Hook ///  public Action AddSwaggerGenAction { get; set; } }

3. 版本控制默认参数接口实现 SwaggerDefaultValueFilter.cs

    public class SwaggerDefaultValueFilter : IOperationFilter
    {
        public void Apply(Swashbuckle.AspNetCore.Swagger.Operation operation, OperationFilterContext context) { // REF: https://github.com/domaindrivendev/Swashbuckle.AspNetCore/issues/412 // REF: https://github.com/domaindrivendev/Swashbuckle.AspNetCore/pull/413 foreach (var parameter in operation.Parameters.OfType()) { var description = context.ApiDescription.ParameterDescriptions.FirstOrDefault(p => p.Name == parameter.Name); if (description == null) return; if (parameter.Description == null) { parameter.Description = description.ModelMetadata.Description; } if (description.RouteInfo != null) { parameter.Required |= !description.RouteInfo.IsOptional; if (parameter.Default == null) parameter.Default = description.RouteInfo.DefaultValue; } } }

4. CustomSwaggerServiceCollectionExtensions.cs

    public static class CustomSwaggerServiceCollectionExtensions
    {
        public static IServiceCollection AddCustomSwagger(this IServiceCollection services) { return AddCustomSwagger(services, new CustsomSwaggerOptions()); } public static IServiceCollection AddCustomSwagger(this IServiceCollection services, CustsomSwaggerOptions options) { services.AddSwaggerGen(c => { if (options.ApiVersions == null) return; foreach (var version in options.ApiVersions) { c.SwaggerDoc(version, new Info { Title = options.ProjectName, Version = version }); } c.OperationFilter(); options.AddSwaggerGenAction?.Invoke(c); }); return services; } }

5. SwaggerBuilderExtensions.cs

    public static class SwaggerBuilderExtensions
    {
        public static IApplicationBuilder UseCustomSwagger(this IApplicationBuilder app) { return UseCustomSwagger(app, new CustsomSwaggerOptions()); } public static IApplicationBuilder UseCustomSwagger(this IApplicationBuilder app, CustsomSwaggerOptions options) { app.UseSwagger(opt => { if (options.UseSwaggerAction == null) return; options.UseSwaggerAction(opt); }); app.UseSwaggerUI(c => { if (options.ApiVersions == null) return; c.RoutePrefix = options.RoutePrefix; c.DocumentTitle = options.ProjectName; if (options.UseCustomIndex) { c.UseCustomSwaggerIndex(); } foreach (var item in options.ApiVersions) { c.SwaggerEndpoint($"/swagger/{item}/swagger.json", $"{item}"); } options.UseSwaggerUIAction?.Invoke(c); }); return app; } ///  /// 使用自定义首页 ///  ///  public static void UseCustomSwaggerIndex(this SwaggerUIOptions c) { var currentAssembly = typeof(CustsomSwaggerOptions).GetTypeInfo().Assembly; c.IndexStream = () => currentAssembly.GetManifestResourceStream($"{currentAssembly.GetName().Name}.index.html"); } }

6. 模型初始化

    private CustsomSwaggerOptions CURRENT_SWAGGER_OPTIONS = new CustsomSwaggerOptions()
    {
        ProjectName = "墨玄涯博客接口",
        ApiVersions = new string[] { "v1", "v2" },//要显示的版本 UseCustomIndex = true, RoutePrefix = "swagger", AddSwaggerGenAction = c => { var filePath = System.IO.Path.Combine(System.AppContext.BaseDirectory, typeof(Program).GetTypeInfo().Assembly.GetName().Name + ".xml"); c.IncludeXmlComments(filePath, true); }, UseSwaggerAction = c => { }, UseSwaggerUIAction = c => { } };

7. 在 api 项目中使用

添加对新建类库的引用,并在 webapi 项目中启用版本管理需要为输出项目添加 Nuget 包:Microsoft.AspNetCore.Mvc.VersioningMicrosoft.AspNetCore.Mvc.Versioning.ApiExplorer (如果需要版本管理则添加)

我引用的版本如下

    <PackageReference Include="Microsoft.AspNetCore.Mvc.Versioning" Version="2.3.0" /> <PackageReference Include="Microsoft.AspNetCore.Mvc.Versioning.ApiExplorer" Version="2.2.0" />

Startup.cs 代码

    public void ConfigureServices(IServiceCollection services) { services.AddMvc().SetCompatibilityVersion(CompatibilityVersion.Version_2_1); //版本控制 services.AddMvcCore().AddVersionedApiExplorer(o => o.GroupNameFormat = "'v'VVV"); services.AddApiVersioning(option => { // allow a client to call you without specifying an api version // since we haven't configured it otherwise, the assumed api version will be 1.0 option.AssumeDefaultVersionWhenUnspecified = true; option.ReportApiVersions = false; }); //custom swagger services.AddCustomSwagger(CURRENT_SWAGGER_OPTIONS); } // This method gets called by the runtime. Use this method to configure the HTTP request pipeline. public void Configure(IApplicationBuilder app, IHostingEnvironment env, IApiVersionDescriptionProvider provider) { if (env.IsDevelopment()) { app.UseDeveloperExceptionPage(); } //custom swagger //自动检测存在的版本 // CURRENT_SWAGGER_OPTIONS.ApiVersions = provider.ApiVersionDescriptions.Select(s => s.GroupName).ToArray(); app.UseCustomSwagger(CURRENT_SWAGGER_OPTIONS); app.UseMvc(); }

关键代码拆解

action 方法的 xml 注释

new CustsomSwaggerOptions(){
    AddSwaggerGenAction = c =>
    {
        var filePath = System.IO.Path.Combine(System.AppContext.BaseDirectory, typeof(Program).GetTypeInfo().Assembly.GetName().Name + ".xml");
        //controller及action注释 c.IncludeXmlComments(filePath, true); } }

当然还需要生成xml,编辑解决方案添加(或者在vs中项目属性->生成->勾选生成xml文档文件)如下配置片段

  <PropertyGroup Condition="'$(Configuration)|$(Platform)'=='Release|AnyCPU'">
    <DocumentationFile>.\项目名称.xmlDocumentationFile> PropertyGroup> <PropertyGroup Condition="'$(Configuration)|$(Platform)'=='Debug|AnyCPU'"> <DocumentationFile>.\项目名称.xmlDocumentationFile> PropertyGroup>

目前.net core2.1我这会将此 xml 生成到项目目录,故可能需要将其加入.gitignore中。

版本控制

添加 Nuget 包:Microsoft.AspNetCore.Mvc.VersioningMicrosoft.AspNetCore.Mvc.Versioning.ApiExplorer
并在 ConfigureServices 中设置

    //版本控制
    services.AddMvcCore().AddVersionedApiExplorer(o => o.GroupNameFormat = "'v'VVV");
    services.AddApiVersioning(option =>
    {
        // allow a client to call you without specifying an api version
        // since we haven't configured it otherwise, the assumed api version will be 1.0
        option.AssumeDefaultVersionWhenUnspecified = true; option.ReportApiVersions = false; });

controller 使用

    /// 
    /// 测试接口 ///  [ApiVersion("1.0")] [Route("api/v{api-version:apiVersion}/test")] [ApiController] public class TestController : ControllerBase { }

自定义主题

将 index.html 修改为内嵌资源就可以使用GetManifestResourceStream获取文件流,使用此 html,可以自己使用var configObject = JSON.parse('%(ConfigObject)');获取到 swagger 的配置信息,从而根据此信息去写自己的主题即可。

    /// 
    /// 使用自定义首页 ///  ///  public static void UseCustomSwaggerIndex(this SwaggerUIOptions c) { var currentAssembly = typeof(CustsomSwaggerOptions).GetTypeInfo().Assembly; c.IndexStream = () => currentAssembly.GetManifestResourceStream($"{currentAssembly.GetName().Name}.index.html"); }

若想注入 css,js 则在 UseSwaggerUIAction 委托中调用对应的方法接口,官方文档

另外,目前 swagger-ui 3.19.0 并不支持多语言,不过可以根据需要使用 js 去修改一些东西
比如在 index.html 的 onload 事件中这样去修改头部信息

document.getElementsByTagName(
  'span'
)[0].innerText = document
  .getElementsByTagName('span')[0] .innerText.replace('swagger', '项目接口文档') document.getElementsByTagName( 'span' )[1].innerText = document .getElementsByTagName('span')[1] .innerText.replace('Select a spec', '版本选择')

在找汉化解决方案时追踪到 Swashbuckle.AspNetCore3.0 主题时使用的swagger-ui 为 3.19.0,从issues2488了解到目前不支持多语言,其他的问题也可以查看此仓库
在使用过程中遇到的问题,基本上 readme 和 issues 都有答案,遇到问题多多阅读即可
