带有Authorize属性的HotChocolate，如何获取当前登录的用户？

Question

我使用带有来自HotChocolate.AspNetCore.Authorization的[Authorize]属性的HotChocolate实现了GraphQL突变，以在我的GraphQL端点上强制授权。

这工作得很好，我只能在我以管理员身份登录后调用变异...

..。但是现在我想检索授权的用户，但是我似乎找不到这样做的方法。

[ExtendObjectType(Name = "Mutation")]
[Authorize(Roles = new[] { "Administrators" })]
public class MyMutations
{
    public bool SomeMethod()
    {
        // In a regular Web API controller, you can do User.Identity.Name to fetch the user name of the current user.  What is the equivalent in Hot Chocolate?
        var userName = "";


        return false;
    }
}

有什么想法吗？

HotChocolate使用asp.net核心身份验证机制，因此您可以使用HttpContext获取用户。

[ExtendObjectType(Name = "Mutation")]
[Authorize(Roles = new[] { "Administrators" })]
public class MyMutations
{
    public bool SomeMethod([Service] IHttpContextAccessor contextAccessor)
    {
        var user = contextAccessor.HttpContext.User; // <-> There is your user

        // In a regular Web API controller, you can do User.Identity.Name to fetch the user name of the current user.  What is the equivalent in Hot Chocolate?
        var userName = "";


        return false;
    }
}
