使用Thinktecture.IdentityModel进行CORS。 httpContext为null并导致异常

i have installed the nuget package: "Thinktecture.IdentityModel" in order to open my API for CORS requests. I followed the instructions for opening the web api as given here:

我已经安装了nuget包：“Thinktecture.IdentityModel”，以便为CORS请求打开我的API。我按照这里给出的打开web api的说明进行了操作：

with the only difference of allowing all origins (just to see that it works) and changing the resource name to fit the controller I have. however on any request I get an exception thrown saying that httpContext is null (this is thrown from inside the package code).

唯一的区别是允许所有来源（只是为了看它工作）和更改资源名称以适应我拥有的控制器。但是在任何请求中我都会抛出一个异常，说httpContext为null（这是从包代码中抛出的）。

what could be the reason?

可能是什么原因？

edit: if you can't answer, perhaps tell me what other information might help you answer? at this point even wild guesses will be appreciated.

Do you selfhost your API? HttpContext is only available when hosting in IIS (Express).

你自己托管你的API吗？ HttpContext仅在IIS（Express）中托管时可用。
