Question

我已经按照一些教程进行了工作，但由于某种原因，我无法显示UI，但是创建了Swagger Json。我看过的最后一个教程是here。

我的设置是这样的：

Nuget Package： Swashbuckle.AspNetCore(1.0.0)

ConfigureServices方法：

services.AddSwaggerGen(options =>
            {
                options.SwaggerDoc("v1",
                    new Info
                    {
                        Title = "MediatR Example",
                        Version = "v1",
                        Description = "Trying out the MediatR library to simplify Request and Response logic.",
                        TermsOfService = "WTFPL",
                        Contact = new Contact
                        {
                            Email = "",
                            Name = "",
                            Url = "https://github.com/CubicleJockey/MediatR-Playground"
                        }
                    }
                );

                var xmlDocFile = Path.Combine(PlatformServices.Default.Application.ApplicationBasePath, @"MediatR-Messages.Api.xml");
                options.IncludeXmlComments(xmlDocFile);
                options.DescribeAllEnumsAsStrings();
            });

Configure方法：

 app.UseMvcWithDefaultRoute();

            // Enable middleware to serve generated Swagger as a JSON endpoint.
            app.UseSwagger();

            // Enable middleware to serve swagger-ui (HTML, JS, CSS etc.), specifying the Swagger JSON endpoint
            app.UseSwaggerUI(config =>
            {
                config.SwaggerEndpoint("/swagger/v1/swagger.json", "V1 Docs");
            });

launchSettings.json：

"IIS Express": {
      "commandName": "IISExpress",
      "launchBrowser": true,
      "launchUrl": "swagger/",
      "environmentVariables": {
        "ASPNETCORE_ENVIRONMENT": "Development"
      }
    },

运行和访问Swagger JSON url会生成相应的JSON：

   {
   "swagger":"2.0",
   "info":{
      "version":"v1",

         }
      }
   },
   "securityDefinitions":{

   }
}

访问默认的Swagger UI网址时，我得到了404.尝试了一些变体。

本地主机：64881 /招摇/
本地主机：64881 /招摇/ UI
本地主机：64881 /招摇/ index.html中
本地主机：64881 /招摇/ UI / index.html中

以上所有都返回404.这些都取决于版本。我错过了什么

我的完整源代码可以在GitHub上找到here。这是这个问题的一个分支，所以代码符合我的要求。

Answer 1

下载并测试您的代码后，您似乎必须将以下NuGet包添加到您的项目中：

Microsoft.AspNetCore.StaticFiles

您可以通过NuGet管理器或将以下行添加到.csproj <ItemGroup>

<PackageReference Include="Microsoft.AspNetCore.StaticFiles" Version="2.0.0" />

Answer 2

我的诀窍是什么：

删除部署文件夹中的所有旧文件（我尝试使用IIS，也适用于其他托管类型）
将所有Microsoft.AspNetCore.*个软件包替换为Microsoft.AspNetCore.All元软件包 - 有关详细信息，请参阅this post。
[可选] 如果出现副作用，请重新安装Swashbuckle.AspNetCore包（不需要其他Swashbuckle.AspNetCore.*个包裹）
确保项目文件中包含这2个包（这足以使其正常工作）：
- PackageReference Include="Microsoft.AspNetCore.All" Version="2.0.0"
- PackageReference Include="Swashbuckle.AspNetCore" Version="1.0.0"
发布（或通过复制文件进行部署）到部署文件夹。现在它应该工作。

注意：如果您的API中有重复的模型名称，有时会失败（在这种情况下，它会在浏览器中显示一些不明确的错误）;）

Answer 3

尝试删除.vs文件夹。在升级到ASP.NET Core 2.1之后为我修复了它

Answer 4

我在几个小时内遇到了同样的问题，但是使用的端口被Chrome浏览器认为是不安全的（文字说明这是谨慎的，很容易遗漏）。将来对某些人来说这可能会派上用场。

Answer 5

我有同样的问题，我缺少HttpMethod绑定。

System.NotSupportedException：动作需要Swagger 2.0的显式HttpMethod绑定

.NET Core 2和SwashBuckle Swagger UI未显示
