【中文标题】Asp.net Core 电子邮件发件人在注册页面中不起作用【英文标题】：Asp.net Core Email Sender is not working in Registration page 【发布时间】：2022-01-04 20:27:00 【问题描述】：我正在尝试使用 asp.net 身份设置一个 asp.net core razor 页面应用程序。
我已经完成了所有设置，我正在尝试生成用于注册的电子邮件，但代码如下：
await _emailSender.SendEmailAsync(Input.Email, "Confirm your email", $"Please confirm your account by <a href='htmlEncoder.Default.Encode(value: callbackUrl)'>clicking here</a>.").ConfigureAwait(false);
没有被击中。就像它甚至不会调试到它一样，因此我的注册电子邮件没有被发送或生成。这些值保存在我的 SQL Server 数据库中，没有任何问题。
这是我要进行的设置：

logger.Debug("init main");
CreateHostBuilder(args).Build().Run();
catch (Exception exception)
// NLog: catch setup errors
logger.Error(exception, "Stopped program because of exception");
throw;
finally

【问题讨论】：
【参考方案1】：我想通了：
内部有一个IEmailSender 接口：
using Microsoft.AspNetCore.Identity.UI.Services;
我的IEmailSender 并没有指向我创建的本地地址。
以下是更改和修复。
现在正在正确发送电子邮件以进行注册。
这是我的代码更改：
