Mailgun - 401 禁止

Question

我尝试使用 mailgun 发送电子邮件。我使用 node.js (nest.js)，这是我的邮件服务。我应该改变什么？当我尝试发送第一封电子邮件（mailgun 官方网站中的描述）时，我收到了相同的错误消息。

import { Injectable } from '@nestjs/common';
import * as Mailgun from 'mailgun-js';
import { IMailGunData } from './interfaces/mail.interface';
import { ConfigService } from '../config/config.service';

@Injectable()
export class MailService {
  private mg: Mailgun.Mailgun;

  constructor(private readonly configService: ConfigService) {
    this.mg = Mailgun({
      apiKey: this.configService.get('MAILGUN_API_KEY'),
      domain: this.configService.get('MAILGUN_API_DOMAIN'),
    });
  }

  send(data: IMailGunData): Promise<Mailgun.messages.SendResponse> {
    console.log(data);
    console.log(this.mg);
    return new Promise((res, rej) => {
      this.mg.messages().send(data, function (error, body) {
        if (error) {
          console.log(error);
          rej(error);
        }
        res(body);
      });
    });
  }
}

当我尝试发送消息时，我收到带有禁止描述的 401 错误。

我的 mg (console.log(this.mg))

Mailgun {
  username: 'api',
  apiKey: '920d6161ca860e7b84d9de75e14exxx-xxx-xxx',
  publicApiKey: undefined,
  domain: 'lokalne-dobrodziejstwa.pl',
  auth: 'api:920d6161ca860e7b84d9de75e14exxx-xxx-xxx',
  mute: false,
  timeout: undefined,
  host: 'api.mailgun.net',
  endpoint: '/v3',
  protocol: 'https:',
  port: 443,
  retry: 1,
  testMode: undefined,
  testModeLogger: undefined,
  options: {
    host: 'api.mailgun.net',
    endpoint: '/v3',
    protocol: 'https:',
    port: 443,
    auth: 'api:920d6161ca860e7b84d9de75e14exxx-xxx-xxx',
    proxy: undefined,
    timeout: undefined,
    retry: 1,
    testMode: undefined,
    testModeLogger: undefined
  },
  mailgunTokens: {}
}

我的电子邮件正文

{
  from: 'rejestracja@lokalne-dobrodziejstwa.pl',
  to: 'me@gmail.com',
  subject: 'Verify User',
  html: '\n' +
    '                <h3>Hello me@gmail.com!</h3>\n' +
    '            '
}

Answer 1

当我的域位于欧盟区域时，我遇到了这个问题。当您使用欧盟区域时，您必须在配置中指定它 - Mailgun 没有明确解释。

所以它会是这样的：

var mailgun = require("mailgun-js")({
  apiKey: API_KEY,
  domain: DOMAIN,
  host: "api.eu.mailgun.net",
});

Answer 2

欧盟用户：对于 mailgun v3，您必须在 url 选项中指定欧盟端点，mailgun.client()如下所示：

const API_KEY = "xxxxxxxxXxxxxxxxxxxxxxxxxxxx-xxxxxxx-xxxxxx";
const DOMAIN = "mydomaim.com";

const formData = require('form-data');
const Mailgun = require('mailgun.js');

const mailgun = new Mailgun(formData);
const client = mailgun.client({
  username: 'api',
  key: API_KEY,
  url:"https://api.eu.mailgun.net"
});
// console.log(client)

const messageData = {
  from: 'Yoopster <joep@mydomain.com>',
  to: 'mybestbuddy@gmail.com',
  subject: 'Hello',
  text: 'Testing some Mailgun awesomeness!'
};

client.messages.create(DOMAIN, messageData)
  .then((res) => {
    console.log(res);
  })
  .catch((err) => {
    console.error(err);
  });

Answer 3

尝试通过控制台中的以下命令向自己发送电子邮件（帐户电子邮件）：

curl -s --user 'api:YOUR_API_KEY' \
    https://api.mailgun.net/v3/YOUR_DOMAIN_NAME/messages \
    -F from='Excited User <mailgun@YOUR_DOMAIN_NAME>' \
    -F to=YOU@YOUR_DOMAIN_NAME \
    -F to=bar@example.com \
    -F subject='Hello' \
    -F text='Testing some Mailgun awesomeness!'

有效吗？

如果不是..我假设您已经正确编写了 api 和域，因此稍后如果您有免费帐户，您应该在概述部分检查授权收件人（您无法在试用帐户上向任何地方发送电子邮件，您必须先输入它）

如果您没有找到解决方案，这就是我完成邮件服务（工作）的方式，因此您可以尝试一下，我使用nodemailer来执行此操作：

import { Injectable, InternalServerErrorException, OnModuleInit } from '@nestjs/common';
import { readFileSync } from 'fs';
import { compile } from 'handlebars';
import { join } from 'path';
import * as nodemailer from 'nodemailer';
import { Options } from 'nodemailer/lib/mailer';
import * as mg from 'nodemailer-mailgun-transport';

import { IReplacement } from './replacements/replacement';
import { ResetPasswordReplacement } from './replacements/reset-password.replacement';

@Injectable()
export class MailService implements OnModuleInit {
  private transporter: nodemailer.Transporter;

  onModuleInit(): void {
    this.transporter = this.getMailConfig(); 
  }

  sendResetPasswordMail(email: string, firstName: string = '', lastName: string = ''): void { // this is just example method with template but you can use sendmail directly from sendMail method
    const resetPasswordReplacement = new ResetPasswordReplacement({
      firstName,
      lastName,
      email,
    });

    this.sendMail(
      proccess.env.MailBoxAddress),
      email,
      'Change password',
      this.createTemplate('reset-password', resetPasswordReplacement),
    );
  }

  sendMail(from: string, to: string, subject: string, body: string): void {
    const mailOptions: Options = { from, to, subject, html: body };

    return this.transporter.sendMail(mailOptions, (error) => {
      if (error) {
        throw new InternalServerErrorException('Error');
      }
    });
  }

  private getMailConfig(): any {
    return nodemailer.createTransport(mg({
      auth: {
        api_key: proccess.env.MailApiKey,
        domain: proccess.env.MailDomain
      },
    }));
  }

  private createTemplate(fileName: string, replacements: IReplacement): string {
    const templateFile = readFileSync(join(__dirname, 'templates', `${fileName}.html`), { encoding: 'utf-8' });
    const template = compile(templateFile);
    return template(replacements);
  }
}

和

const templateFile = readFileSync(join(__dirname, 'templates', `${fileName}.html`), { encoding: 'utf-8' });

定义包含内容的 html 文件的位置及其外观（在本例中为 Reset-password.html）：

<!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="UTF-8">
  <meta name="viewport" content="width=device-width, initial-scale=1.0">
  <meta http-equiv="X-UA-Compatible" content="ie=edge">
  <title>Password reset</title>
</head>
<body>
  <div>Welcome {{firstName}} {{lastName}}</div>
</body>
</html>

并且 {{}} 中的值将自动被库替换

在此示例中，ResetPasswordReplacement是它的唯一基本对象，其中包含 3 个属性，并且由空接口 IReplacement 继承 - 使其仅用于在模板文件中定义值
