从Nestjs中的.env文件读取端口号

我有.env文件中定义的详细信息。以下是我的代码。

import { Module } from '@nestjs/common';
import { MailService } from './mail.service';
import { MailController } from './mail.controller';
import { MailerModule } from '@nestjs-modules/mailer';
import { HandlebarsAdapter}  from '@nestjs-modules/mailer/dist/adapters/handlebars.adapter';
import { join } from 'path';


@Module({
  imports:[
     MailerModule.forRoot({
      transport:{
        host: process.env.SMTP_HOST,
        port: 1025,
        ignoreTLS: true,
        secure: false,
        auth:{
          user:'[email protected]',
          pass:'Ddixit90@@',
        },
      },
      defaults:{
           from: '"No Reply" <no-reply@localhost>',
      },
      template:{
        dir:join(__dirname,'templates'),
        adapter: new HandlebarsAdapter(),
        options:{
          strict:false,
        },
      }
     }
      
     )
  ],
  controllers: [MailController],
  providers: [MailService],
  exports:[MailService]
})
export class MailModule {}

主机：process.env.smtp_host正常工作。但是，当我编写process.env.smtp_port时，它说您无法将字符串分配给编号。

当我编写ParseInt（Process.env.smtp_port）时，它仍然无法正常工作。如何从.env文件分配port文件

I have details defined in .env file. Below is my code.

import { Module } from '@nestjs/common';
import { MailService } from './mail.service';
import { MailController } from './mail.controller';
import { MailerModule } from '@nestjs-modules/mailer';
import { HandlebarsAdapter}  from '@nestjs-modules/mailer/dist/adapters/handlebars.adapter';
import { join } from 'path';


@Module({
  imports:[
     MailerModule.forRoot({
      transport:{
        host: process.env.SMTP_HOST,
        port: 1025,
        ignoreTLS: true,
        secure: false,
        auth:{
          user:'[email protected]',
          pass:'Ddixit90@@',
        },
      },
      defaults:{
           from: '"No Reply" <no-reply@localhost>',
      },
      template:{
        dir:join(__dirname,'templates'),
        adapter: new HandlebarsAdapter(),
        options:{
          strict:false,
        },
      }
     }
      
     )
  ],
  controllers: [MailController],
  providers: [MailService],
  exports:[MailService]
})
export class MailModule {}

host: process.env.SMTP_HOST is working properly. but when I am writing process.env.SMTP_PORT it is saying you can not assign string to number.

when I wrote parseInt(process.env.SMTP_PORT) it is still not working. how to assign port from .env file

端口： +Process.env.smtp_port应将其施放到一个数字。如果有不同的东西，也许可以共享您遇到的错误。

另一种选择是将配置服务用于MailerModule并使用工厂。这是一个示例实现：

MailerModule.forRootAsync({
            useFactory: async (config: ConfigService) => ({
                transport: {
                    host: process.env.SMTP_HOST,
                    port: 1025,
                    ignoreTLS: true,
                    secure: false,
                    auth: {
                        user: "[email protected]",
                        pass: "Ddixit90@@",
                    },
                },
                defaults: {
                    from: '"No Reply" <no-reply@localhost>',
                },
                template: {
                    dir: join(__dirname, "templates"),
                    adapter: new HandlebarsAdapter(),
                    options: {
                        strict: false,
                    },
                },
            }),
            inject: [ConfigService],
        }),

这样做，config.get能够通过属性确定类型。否则，您可以使用config.get＆lt; number＆gt;来定义它。

port: +process.env.SMTP_PORT should work casting it to a number. If there is something different, perhaps share the error you are getting.

An alternative would be to use the config service for the MailerModule and use the factory. Here is an example implementation of that:

MailerModule.forRootAsync({
            useFactory: async (config: ConfigService) => ({
                transport: {
                    host: process.env.SMTP_HOST,
                    port: 1025,
                    ignoreTLS: true,
                    secure: false,
                    auth: {
                        user: "[email protected]",
                        pass: "Ddixit90@@",
                    },
                },
                defaults: {
                    from: '"No Reply" <no-reply@localhost>',
                },
                template: {
                    dir: join(__dirname, "templates"),
                    adapter: new HandlebarsAdapter(),
                    options: {
                        strict: false,
                    },
                },
            }),
            inject: [ConfigService],
        }),

Doing it this way, config.get is able to determine the type by the property. Else you can define it with config.get<number>
