C# Web Api 寻找 PFX 证书，即使它不应该是

如何解决C# Web Api 寻找 PFX 证书，即使它不应该是

我正在开发一个 C# web api (.NET 5.0)，直到最近才使用 pfx 文件来签署 JWT。我们切换到 HMAC，因为我们不想再使用 pfx 文件。我移动了 pfx 文件，所以系统找不到它们（因为它们不应该被引用）但是当我尝试运行我的应用程序时，我得到了这个异常：

应用程序不应该寻找 pfx 文件（当我调试时，startup.cs 中的所有代码似乎都运行良好），但它在 CreateHostBuilder(args).Build().Run(); 的 Program.cs 中抛出了这个奇怪的异常。显然，我的同事没有同样的问题，所以我假设我的机器有些奇怪，也许是我搞砸了我的 Windows 10 设置？也许是注册表项或类似的东西？在这一点上，欢迎任何关于可能发生的事情的想法（无论它们听起来多么奇怪）。

解决方法

原来，这是因为我的环境变量在Windows中设置：

library(data.table)
irisdt <- as.data.table(iris)

irisdt[,new := cut(Sepal.Width,breaks=c(0,36,72,108,Inf),include.lowest=TRUE,labels=c("Very_Low","Low","High","Very_High"))]

清除那些和重新启动固定的问题。
