swagger - .NET Core 2 和 SwashBuckle Swagger UI 未显示

Question

我已经遵循了一些教程，并且已经在工作中使用了它，但是由于某种原因，我无法显示 UI，但是创建了 Swagger Json。我看的最后一个教程是 here .

我的设置是这样的:

Nuget 套餐: 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"
      }
    },

运行并访问 Swagger JSON url 会生成适当的 JSON:

   "securityDefinitions":{

   }
}

访问默认的 Swagger UI url 时，我得到 404。尝试了一些变体。

本地主机:64881/swagger/

本地主机:64881/swagger/ui

本地主机:64881/swagger/index.html

本地主机:64881/swagger/ui/index.html

以上所有都返回 404。这些之前都有效，具体取决于版本。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

对我有什么好处:

从部署文件夹中删除所有旧文件 (我尝试过 IIS ，也适用于其他托管类型)

全部替换 Microsoft.AspNetCore.*包裹 Microsoft.AspNetCore.All元包 - 见 this post详情。

[可选] 以防万一，重新安装 Swashbuckle.AspNetCore包(不需要其他 Swashbuckle.AspNetCore.* 包)

确保项目文件中有这 2 个包(足以使其工作):

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)到您的部署文件夹。
现在它应该可以工作了。

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