Web API 2 swagger文档的根路径

Question

我有Web API 2，并使用[Swashbuckle] [1]配置了Swagger，如下所示：

private static void ConfigureSwagger(HttpConfiguration config)
{


    // add the versioned IApiExplorer and capture the strongly-typed implementation (e.g. VersionedApiExplorer vs IApiExplorer)
    // note: the specified format code will format the version as "'v'major[.minor][-status]"
    var apiExplorer = config.AddVersionedApiExplorer(o => o.GroupNameFormat = "'v'VVV");


    config
        .EnableSwagger(swagger =>
        {
            // build a swagger document and endpoint for each discovered API version
            swagger.MultipleApiVersions(
                (apiDescription, version) => apiDescription.GetGroupName() == version,
                info =>
                {
                    foreach (var group in apiExplorer.ApiDescriptions)
                    {
                        var description = "AAAA API.";

                        if (group.IsDeprecated)
                        {
                            description += " This API version has been deprecated.";
                        }

                        info.Version(group.Name, $"AAAA API {group.ApiVersion}")
                            .Contact(c => c.Name("AAAA").Email("AAAA@AAAA.com"))
                            .Description(description)
                            .License(l => l.Name("AAAA").Url("www.AAAA.com"))
                            .TermsOfService("AAAA. All rights reserved.");
                    }
                });

            // add a custom operation filter which sets default values
            swagger.OperationFilter<SwaggerDefaultValues>();

            // integrate xml comments
            swagger.IncludeXmlComments(XmlCommentsFilePath);

            //swagger.RootUrl(req => SwaggerDocsConfig.DefaultRootUrlResolver(req) + "/api");
        })
    .EnableSwaggerUi(swagger => swagger.EnableDiscoveryUrlSelector());

}

在本地运行时，一切运行正常，我可以看到带有api端点的大页面。 现在，当我们将其部署到默认网站\\ AAAA下的IIS中时，路径始终被解析为默认网站的根目录，而不是AAAA（WebAPI）应用程序的根目录

有谁知道可能是什么问题？

从这里回答。

OWIN托管在IIS中-错误的VirtualPathRoot处理当您在OWIN / SystemWeb之上托管Web API 2时，默认情况下Swashbuckle无法正确解析VirtualPathRoot。

您必须在启动时在HttpConfiguration中显式设置VirtualPathRoot，或执行如下自定义操作以修复自动发现：

httpConfiguration.EnableSwagger(c => 
{
    c.RootUrl(req =>
        req.RequestUri.GetLeftPart(UriPartial.Authority) +
        req.GetRequestContext().VirtualPathRoot.TrimEnd('/'));
}
