激活HttpContext时出错 - 可以使用多个匹配的绑定

public void ConfigureServices(IServiceCollection services)
{
    services.AddHttpContextAccessor();
    // ...
}

public class MyClass
{
    private readonly IHttpContextAccessor _httpContextAccessor;

    public MyClass(IHttpContextAccessor httpContextAccessor)
    {
        _httpContextAccessor = httpContextAccessor;
    }

    public void MyMethod()
    {
        var httpContext = _httpContextAccessor.HttpContext;
        // ...
    }
}

public void MyMethod()
{
    var httpContext = _httpContextAccessor.HttpContext;
    httpContext.Items["myKey"] = "myValue";
    // ...
}

public void ConfigureServices(IServiceCollection services)
{
    services.AddHttpContextAccessor();
    services.AddTransient<IHttpContextAccessor, HttpContextAccessor>();
    // ...
}
