Question

我正在开发一个ASP.NET Core 2 api，最近我一直在尝试创建类似于大多数网站的“密码重置功能”，通过向该帐户发送电子邮件以更改密码。

所以我用谷歌搜索并写了一些部分有用的东西。部分我的意思是，它在localhost中按预期工作，但我在亚马逊网络服务（AWS）上托管我的应用程序，并且出于某种原因，当它上传时，电子邮件永远不会被发送。通过这个我的意思是api返回一个内部服务器错误，我不知道如何调试在主机上失败的东西

我知道有亚马逊SES但不幸的是我无法使用它，因为我的api托管在巴西，亚马逊SES在我所在的地区尚不可用。

anyonne是否知道可能出现的问题，甚至是如何调试它？

以下是我目前用来发送电子邮件的代码

基

public interface IEmailService
{
    HttpStatusCode SendEmail(string email, string subject, string body);
}

public class EmailService : IEmailService
{
    private readonly IConfiguration _config;
    public static NetworkCredential credential;
    public static SmtpClient client;


    public EmailService(IConfigurationRoot c)
    {
        _config = c;

        credential = new NetworkCredential()
        {
            UserName = _config["EmailSettings:Email"],
            Password = _config["EmailSettings:Password"]
        };

        client = new SmtpClient()
        {
            Credentials = credential,
            Host = _config["EmailSettings:Host"],
            Port = int.Parse(_config["EmailSettings:Port"]),
            EnableSsl = true

        };

    }


    public HttpStatusCode SendEmail(string email, string subject, string body)
    {
        using (client)
        {
            using (var message = new MailMessage())
            {
                message.To.Add(new MailAddress(email));
                message.From = new MailAddress(_config["EmailSettings:Email"]);
                message.Subject = subject;
                message.Body = body;
                message.IsBodyHtml = true;
                try
                {
                    client.Send(message);
                    return HttpStatusCode.OK;
                }
                catch
                {
                    return HttpStatusCode.InternalServerError;
                }
            }

        }
    }


    // Body builder, just
    public static string PasswordResetBody(string token)
    {
        StringBuilder body = new StringBuilder();
        body.AppendFormat("<h1>My title</h1>");
        body.AppendFormat("<br />");
        body.AppendFormat("<h3>Passw recovery</h3>");
        body.AppendFormat("<br />");
        body.AppendFormat("<p>Automated Msg.</p>");
        body.AppendFormat("<br />");
        body.AppendFormat("<p>Click below</p>");
        body.AppendFormat($"<a href=\"https://www.mywebsite.com/account/reset/{token}\">https://www.mywebsite.com/account/reset/{token}</a>");


        return body.ToString();
    }
}

在控制器上

 public HttpStatusCode SendResetPassword(GetStringModel model)
    {
        ...

        var sentEmail = emailService.SendEmail(model.Data, "MySubject", EmailService.PasswordResetBody(guid.ToString()));
        return sentEmail;
    }

异常

感谢伐木，我用Google搜索并在另一个上找到答案 stackoverflow question

基本上，似乎因为我使用的是Gmail，Google具有位置安全功能，并且它阻止了电子邮件请求。当我信任该设备并接受其工作的活动时。但是，我不确定这是否是最佳方式。

Tseng必须是正确的，我将在另一个地区调查SES，因为我在AWS免费套餐上，因此机器和IP可以随时更改。谷歌可能会再次阻止他们。
