Blazor 中的 SendGrid 电子邮件服务 - 依赖注入或静态方法

我正在 Blazor 应用程序 (.NET 5) 中设置 SendGrid 电子邮件发送器。

根据 SendGrid 文档和示例，他们正在编写一个签名为的方法static async Task然后他们await来自他们的 API 的响应。他们的示例代码立即运行Main()并且不显示任何方法调用。

使用它作为静态方法是否违反了我应该如何使用依赖注入？我是否应该将此 EmailSender 类注册为具有依赖注入的服务，然后将其注入到需要发送电子邮件的组件中？

SendGrid 示例中的代码：

private static void Main()
{
    Execute().Wait();
}

static async Task Execute()
{
    //Boilerplate code setting up email from/to/apiKey etc removed
    var response = await client.SendEmailAsync(msg);
}

通过此设置，我可以将 Execute() 方法公开，然后直接将其作为静态方法调用。

制作如下内容是否更合适：

public class EmailService
{
    public async Task SendEmail(string to, string subject, string message)
    {
        //Boilerplate code setting up email from/to/apiKey etc removed
        var response = await client.SendEmailAsync(msg);
    }
}

然后我可以通过 DI 注入并使用该服务，例如：

@inject EmailService emailService

@code {
    //Calling line below in the appropriate spot
    await emailService.SendEmail(to, subject, message);
}

.NET Core 中的通用实现：

启动.cs

using SendGrid.Extensions.DependencyInjection; // nuget package: https://www.nuget.org/packages/SendGrid.Extensions.DependencyInjection

public class Startup
{
    public void ConfigureServices(IServiceCollection services)
    {
        // sendgrid
        services.AddSendGrid(options =>
        {
            options.ApiKey = Environment.GetEnvironmentVariable("SENDGRID_API_KEY");
        });
    }
}

电子邮件控制器.cs

using SendGrid; // nuget package

public class EmailController : ControllerBase
{
    private ISendGridClient _sendGridClient;
    
    public EmailController(ISendGridClient sendGridClient)
    {
        _sendGridClient = sendGridClient;
    }
    
    public IActionResult SendEmail(Email email)
    {
        var emailManager = new EmailManager(_sendGridClient);
        return emailManager.SendEmail(email);
    }
}

电子邮件管理器.cs

using SendGrid;

public class EmailManager
{
    private ISendGridClient _sendGridClient;
    
    public EmailManager(ISendGridClient sendGridClient)
    {
        _sendGridClient = sendGridClient;
    }
    
    public bool SendEmail(Email email)
    {
        ...
        var response = await _sendGridClient.SendEmailAsync(msg);
        ...
    }
}
