2.1.2 基于 NTLMAuth 的认证配置方式


直接配置 pass 密码可能会导致明文密码泄露，我们可以将 pass 字段留空，配置 nt_password 和 lm_password 字段，使用 NTLMAuth 认证模式。此二字段基于 pass 明文生成，其 nodejs 生成方式可借助 httpntlm 模块完成，具体参考如下：


import { ntlm as NTLMAuth } from 'httpntlm';

/** 将输入的邮箱账号密码转换为 NTLMAuth 秘钥(hex)格式并输出 */
const getHashedPwd = () => {
 const passwordPlainText = process.argv.slice(2)[0];

 if (!passwordPlainText) {
 console.log('USEAGE: \n\tnode get-hashed-pwd.js [password]');
 return;
 }

 const nt_password = NTLMAuth.create_NT_hashed_password(passwordPlainText.trim());
 const lm_password = NTLMAuth.create_LM_hashed_password(passwordPlainText.trim());

 // console.log('\n password:', passwordPlainText);
 console.log(` nt_password:`, nt_password.toString('hex'));
 console.log(` lm_password:`, lm_password.toString('hex'));

 return {
 nt_password,
 lm_password,
 };
};

getHashedPwd();



2.2 使用 ews-javascript-api 发送 MS Exchange 邮件


基于 ews-javascript-api 发送邮件的方式，在其官方 wiki 有相关示例，但本人在测试过程中未能成功，具体为无法取得服务器认证，也未能查证具体原因，故以下代码仅作参考：


/**
 * 使用 `ews-javascript-api` 发送(MS Exchange)邮件
 */
export async function sendMailByEwsJApi(options: IEwsSendOptions) {
 const resultInfo = { code: 0, msg: '', result: null };

 if (!options) {
 resultInfo.code = -1001;
 resultInfo.msg = 'Options can not be null';
 } else if (!options.auth) {
 resultInfo.code = -1002;
 resultInfo.msg = 'Options.auth{user,pass} can not be null';
 } else if (!options.auth.user || (!options.auth.pass && !options.auth.lm_password)) {
 resultInfo.code = -1003;
 resultInfo.msg = 'Options.auth.user or Options.auth.password can not be null';
 }

 const ews = require('ews-javascript-api');
 const exch = new ews.ExchangeService(ews.ExchangeVersion.Exchange2010);
 exch.Credentials = new ews.WebCredentials(options.auth.user, options.auth.pass);
 exch.Url = new ews.Uri(options.host);
 ews.EwsLogging.DebugLogEnabled = true; // false to turnoff debugging.

 const msgattach = new ews.EmailMessage(exch);
 msgattach.Subject = options.subject;
 msgattach.Body = new ews.MessageBody(ews.BodyType.HTML, escape(options.html || options.text));
 if (!Array.isArray(options.to)) options.to = [options.to];
 options.to.forEach(to => msgattach.ToRecipients.Add(to));
 // msgattach.Importance = ews.Importance.High;

 // 发送附件
 // msgattach.Attachments.AddFileAttachment('filename to attach.txt', 'c29tZSB0ZXh0');

 try {
 const result = await msgattach.SendAndSaveCopy(); // .Send();
 console.log('DONE!', result);
 resultInfo.result = result;
 } catch (err) {
 console.log('ERROR:', err);
 resultInfo.code = 1001;
 resultInfo.msg = err;
 }
 return resultInfo;
}
