尝试从适配器'NetCoreContainerAdapter'解析服务'System.Boolean'时出错

Question

最近转换到.NET Core后，我在尝试使用我们的任何AuthProviders进行身份验证时遇到以下错误：

"；尝试从适配器"NetCoreContationrAdapter"解析服务"System.Boolean"时出错：对象引用未设置为对象的实例">

我在.NET Core 3.1上使用ServiceStack.Core 5.9.2。

您的SgCredentialsAuthProvider在国际奥委会注册了吗？它只应该作为AuthProvider添加到您的AuthFeature插件注册中。

该错误表明您有一个自动连接的服务或具有公共bool属性或构造函数的依赖项，该属性或构造函数正试图注入从IsAccountLocked((方法调用的不存在的bool依赖项：

public virtual bool IsAccountLocked(IAuthRepository authRepo, IUserAuth userAuth, IAuthTokens tokens=null)
{
if (AccountLockedValidator != null)
return AccountLockedValidator(authRepo, userAuth, tokens);

return userAuth?.LockedDate != null;
}

从其执行情况来看，国际奥委会正试图解决国际奥委会提出的AccountLockedValidator的每个通用论点，但在bool通用论点上失败了：

public Func<IAuthRepository, IUserAuth, IAuthTokens, bool> AccountLockedValidator { get; set; }

删除SgCredentialsAuthProvider的IOC注册，或者如果你正在进行依赖项的自动扫描/自动布线，则忽略它应该可以解决这个问题。
