收件人在 FluentEmail 的后续电子邮件中不断添加

Question

我正在使用 FluentEmail 发送电子邮件，一切正常，除了有一个问题，'To' 收件人不断被添加为每个后续电子邮件。

例如：如果它正在向 someone@abc.com 发送电子邮件：

第一次调用 SendEmailAsync 方法时，它发送电子邮件至：someone@abc.com
第二次调用 SendEmailAsync 方法时，它发送电子邮件至：someone@abc.com;someone@abc.com
第三次调用 SendEmailAsync 方法，它发送电子邮件至： someone@abc.com;someone@abc.com;someone@abc.com

等等。一段时间后真的很长。

我的代码如下所示：

ConfigureServices方法：

// Set email service using FluentEmail
services.AddFluentEmail("myapp@goodboi.com")
        .AddRazorRenderer(@$"{Directory.GetCurrentDirectory()}/Views/")
        .AddSmtpSender("smtp.somecompanyname.com", 25)
        .AddSmtpSender(new System.Net.Mail.SmtpClient() { });

现在电子邮件服务如下所示：

public class FluentEmailService : IFluentEmailService
{
    private readonly IFluentEmail _fluentEmail;
    private readonly ILogger<FluentEmailService> _logger;
    public FluentEmailService(ILogger<FluentEmailService> logger, IFluentEmail fluentEmail)
    {
        _logger = logger;
        _fluentEmail = fluentEmail;
    }

    public async Task<SendResponse> SendEmailAsync<TModel>(string subject, string razorTemplatePath, TModel model, string semicolonSeparatedEmailRecipients)
    {
        var sendResponse = await _fluentEmail
                        .To(semicolonSeparatedEmailRecipients)
                        .Subject(subject)
                        .UsingTemplateFromFile(razorTemplatePath, model)
                        .SendAsync();
        return sendResponse;
    }
}

使用 IFluentEmailFactory 而不是 IFluentEmail 解决了我的问题。

现在电子邮件服务如下所示：

public class FluentEmailService : IFluentEmailService
{
    private readonly IFluentEmailFactory _fluentEmailFactory;
    private readonly ILogger<FluentEmailService> _logger;
    public FluentEmailService(ILogger<FluentEmailService> logger, IFluentEmailFactory fluentEmailFactory)
    {
        _logger = logger;
        _fluentEmailFactory = fluentEmailFactory;
    }

    public async Task<SendResponse> SendEmailAsync<TModel>(string subject, string razorTemplatePath, TModel model, string semicolonSeparatedEmailRecipients)
    {
        var sendResponse = await _fluentEmailFactory
                        .Create()
                        .To(semicolonSeparatedEmailRecipients)
                        .Subject(subject)
                        .UsingTemplateFromFile(razorTemplatePath, model)
                        .SendAsync();
        return sendResponse;
    }
}
