IdentityServer4 默认提供了两种证书加密配置:
services.AddIdentityServer()
.AddDeveloperSigningCredential()
.AddTemporarySigningCredential();
这两种证书加密方式,都是临时使用,每次重启项目的时候,都会重新生成一个新的证书,这时候就会导致一个问题,重启之前生成的access_token
,在重启之后,就不适用了,因为证书改变了,对应的加密方式也改变了,所以,就会出现下面这个问题:
错误信息:
Www-Authenticate:Bearer error="invalid_token", error_description="The signature key was not found"
解决方式,就是始终使用一个证书,我们先这样配置:
services.AddIdentityServer()
.AddDeveloperSigningCredential();
可以查看下AddDeveloperSigningCredential
实现源码,启动项目,IdentityServer4 会在项目目录中生成一个tempkey.rsa
证书文件:

}
AddDeveloperSigningCredential
中代码执行,会先判断tempkey.rsa
证书文件是否存在,如果不存在的话,就创建一个新的tempkey.rsa
证书文件,如果存在的话,就使用此证书文件。
所以,我们配置的时候,传递一个tempkey.rsa
证书文件名,就可以了:
services.AddIdentityServer()
.AddDeveloperSigningCredential("tempkey.rsa");
当然,你也可以对tempkey.rsa
证书文件,进行重命名操作。
