.net - Hangfire 1.6.4 .NET Core - 无法解析依赖项

Question

我正在为我的 .NET Core 项目使用 Hangfire 1.6.4。

这是我的日程 Controller :

    [HttpPost]
    public void Post([FromBody]EmailSchedulerDto emailSchedulerDto)
    {
        // test only
        emailSchedulerDto = new EmailSchedulerDto
        {
            UserId = "",
            Email = "myEmail@gmail.com",
            StoresId = new List<string>(),
            CronPattern = "* * * * *"
        };
        RecurringJob.AddOrUpdate(
            () =>
                _emailScheduler.ScheduleEmail(emailSchedulerDto.UserId, emailSchedulerDto.Email,
                    emailSchedulerDto.StoresId), emailSchedulerDto.CronPattern);
    }

但是我在作业执行过程中出现错误:

// Job ID: #183
using MyProject.Services.Email;

var emailScheduler = Activate<EmailScheduler>();
await emailScheduler.ScheduleEmail(
    "",
    "myEmail@gmail.com",
    FromJson<IEnumerable`1>("[]")
storesId
);

系统.InvalidOperationException

尚未注册“MyProject.Services.Email.EmailScheduler”类型的服务。

我已经像这样注册了 ContainerJobActivator:

public class ContainerJobActivator : JobActivator
{
    private readonly IServiceProvider _serviceProvider;

    public ContainerJobActivator(IServiceProvider serviceProvider)
    {
        _serviceProvider = serviceProvider;
    }

    public override object ActivateJob(Type type)
    {
        return _serviceProvider.GetService(type);
    }
}

在 Startup 类中:

GlobalConfiguration.Configuration.UseActivator(new ContainerJobActivator(services.BuildServiceProvider()));

怎么了？

谢谢!

Answer 1

以下是对我有帮助的内容:1. 像这样注册 Hangfire:

services.AddHangfire(configuration => configuration
                       .UseSqlServerStorage("connection string here"));

2。还有一件事(应该是第一件事):

services.AddScoped<EmailScheduler, EmailScheduler>();

我有一段时间没有将此答案标记为正确答案...但如果没有其他答案，我会做)
