带有EF Core API的ASP.NET Core返回“无法对HTTPS连接进行身份验证”。从邮递员获得请求

Question

作为使用C＃/ ASP.NET Core学习EF Core的练习，我完成了本教程的最后部分：ASP.NET Core Web API with EF Core Code-First Approach。

完成操作后，我就可以从源文件夹运行'dotnet watch run'，并加载端点http://localhost:5000/api/employee，我可以在Chrome中获得响应，从重定向到https://localhost:5001/api/employee个端点。

我被困是因为我想在邮递员中得到同样的答复，但是我只看到以下内容：

这是我在运行服务器的Powershell中看到的：

及以下显示当我运行Postman Get请求时。我猜想这与我的startup.cs的配置有关系...但是我不确定从哪里开始。在此处搜索Stack Overflow时，我遇到了很多有关SSL证书和pfx文件的问题，但与该问题没有特别的关系。我对此并不陌生，在学校里，所以也许我只是错过了答案，因为这超出了我的知识范围？我不明白为什么它可以在chrome中使用，但Postman却不行。
