ASP.NET 核心 5.0 Web API 适用于 IIS 速成，但在 IIS 10 上承载时会给出 404

Question

我在单个解决方案中有一个WEB APP和一个WEB API项目。最近，我们在API项目中添加了Swashbuckle和Swagger UI。现在，当使用IIS Express Swagger在VS中运行表单（调试/不调试）时，Web API工作正常。json可访问，Swagger UI可用https://localhost:/API/docs/index.html然后尝试一下https://localhost:/API/docs/，返回有效输出。

但是，在发布并部署到IIS站点后，它会返回404错误。招摇过市。json已形成，Swagger UI已正确提供https://domain:/API/docs/index.html但在尝试时https://domain:/API/docs/以404响应。（DNS映射正确）。

IIS 10.0详细错误-404.0-未找到
