使用MailjetApi发送5000封邮件时出现NodeJS堆内存溢出错误

我的代码实现 #

function arraySend(array, locals) {
  var mailjetConnect = mailjet.connect(locals.blocks.mailjetparam.username, locals.blocks.mailjetparam.password),
      chunkedArrayMessages = _.chunk(array, 50),
      delay = ms => new Promise(resolve => setTimeout(resolve, ms)),
      promises;

  if (process.env.NODE_ENV.trim() === 'dev') {
    return Promise.resolve();
  } else {
    promises = chunkedArrayMessages.map((messages) => {
      return Promise.all([
        delay(1000),
        mailjetConnect.post('send', { version: 'v3.1' }).request({ Messages: messages }).then(() => {
          return Promise.resolve();
        }).catch(() => {
          return Promise.resolve();
        })
      ]);
    });
    return Promise.all(promises).then(function() {
      return Promise.resolve();
    }).catch(function(err) {
      return Promise.reject(err);
    });
  }
}
