AspNetCore无法加载类型“swashbuck.AspNetCore.SwaggerGen.SwaggerResponseAttribute”

swagger asp.net-core c#

Yahya Hussein · 技术社区 · 7 年前

我有一个ASP.NET Core Web应用程序,在该应用程序中,我使用了下面的swagger:

public void ConfigureServices(IServiceCollection services)
{
    services.AddMvc();
    services.AddSwaggerGen(c =>
    {
        c.OperationFilter<ExamplesOperationFilter>();
        c.OperationFilter<DescriptionOperationFilter>();
        c.SwaggerDoc("v1", new Info
        {
            Version = "v1",
            Title = "API",
            Description = "",
        });
        // Set the comments path for the Swagger JSON and UI.
        var xmlFile = $"{Assembly.GetExecutingAssembly().GetName().Name}.xml";
        var xmlPath = Path.Combine(AppContext.BaseDirectory, xmlFile);
        c.IncludeXmlComments(xmlPath);
    });
}


public void Configure(IApplicationBuilder app, IHostingEnvironment env)
{
    app.UseSwagger();
    app.UseSwaggerUI(c => { c.SwaggerEndpoint("/swagger/v1/swagger.json", "API"); });
    if (env.IsDevelopment())
    {
        app.UseDeveloperExceptionPage();
    }

    app.UseMvc();
}

当我导航到url/swagger时,出现以下错误:

失败:Microsoft.AspNetCore.Server.Kestrel[13] 申请。System.TypeLoadException:无法加载类型来自区域性=中性'.at swashbacker.AspNetCore.Examples.DescriptionOperationFilter.SetResponseModelDescriptions(操作 apiDescription)在 swashbucker.AspNetCore.Examples.DescriptionOperationFilter.Apply(操作操作,OperationFilterContext context)位于 swashbacker.AspNetCore.swagggergen.swagggergenerator.CreateOperation(ApiDescription swashbacker.AspNetCore.SwaggerGen.SwaggerGenerator.CreatePathItem(IEnumerable 1 apiDescriptions, ISchemaRegistry schemaRegistry) at System.Linq.Enumerable.ToDictionary[TSource,TKey,TElement](IEnumerable 来源,Func 2 keySelector, Func IEqualityComparer公司 1 comparer) at Swashbuckle.AspNetCore.SwaggerGen.SwaggerGenerator.CreatePathItems(IEnumerable 1个 swashbuck.AspNetCore.SwaggerGen.SwaggerGenerator.GetSwagger(字符串 documentName,String host,String basePath,String[]schemes)位于 httpContext)在 Microsoft.AspNetCore.Server.Kestrel.Core.Internal.Http.HttpProtocol.ProcessRequests[TContext](IHTTP应用程序'1

我安装的nuget包是:

swashbucker.AspNetCore.Examples版本2.9.0

卸载包

Swashbuckle.AspNetCore.Examples

应该能解决这个问题。新的软件包是(还没试过)-

Swashbuckle.AspNetCore.Filters

(更新) 新的包装很好用

在升级到.netcore 3.0时,这对我们很有用:

1) 安装软件包Swashbuckle.AspNetCore-版本5.0.0-rc4

2) 将代码更改为

    public void ConfigureServices(IServiceCollection services)
    {
        ...
        services.AddSwaggerGen(c =>
                {
                    c.SwaggerDoc("v1", new OpenApiInfo { Title = "WebAPI", Version = "v1" });
                });
        ...
    }

    public void Configure(IApplicationBuilder app, IWebHostEnvironment env,ILoggerFactory loggerFactory)
    {
        ...
        app.UseSwagger();
        app.UseSwaggerUI(c =>
        {
            c.RoutePrefix = "swagger/ui";
            c.SwaggerEndpoint("/swagger/v1/swagger.json", "WebAPI(v1)");
        });
        ...
    }

基本上,以下是在 https://github.com/domaindrivendev/Swashbuckle.AspNetCore/releases/tag/v5.0.0-rc4

这与版本3中的几个重大更改有关。 Here you can find more information.

要修复此问题,请尝试添加 Swashbuckle.AspNetCore.Annotations package.

Install-Package Swashbuckle.AspNetCore.Annotations -Version 3.0.0

对于dotnet核心:

dotnet add package Swashbuckle.AspNetCore.Annotations --version 3.0.0

Release Notes For v3.0.0

要使其在更高版本和ASPNET Core中工作,您需要:

参考nuget swashbleck.AspNetCore.Filters
在内部 AddSwaggerGen 呼叫 ExampleFilters(); (在配置服务中)
IExampleProvider<TargetDtoType> 哪里 TargetDtoType 你的目标类型是你的例子
呼叫 AddSwaggerExamplesFromAssemblyOf<ExampleTypeImplementation> IExampleProvider<TargetDtoType>
