ASP.Net Core 的Razor Pages项目部署在IIS中报错如下：

在前端页面上看到的错误是：400 Bad Request。在Visual Studio中直接运行则没有问题，部署在Linux下也没有问题。里面涉及的问题太多了。这个错误是有关AntiForgeryToken的， 在这里提交一个解决问题的Demo。
在  Startup.cs 文件中的 public void ConfigureServices(IServiceCollection services)方法添加几行。

在IIS里部署ASP.NET Core Web程序可参考：https://lebang2020.cn/details/210322njnautk1.html
