Gmail定时发信脚本修复方案

已知错误点

触发器绑定的函数名不匹配：发信函数定义为sendEmails，但创建触发器时传入的是带空格的send emails，触发时无法找到对应执行函数
语法不规范：代码开头的Function首字母大写不符合JavaScript语法要求，需改为小写function
旧触发器冲突：未清理之前创建的每日触发等旧触发器，可能导致执行逻辑冲突

修正后完整代码

function sendEmails() {
  var emailAddress = 'email@email.com';
  var subject = 'Reminder: reminder';
  var message = 'Content of message';
  MailApp.sendEmail(emailAddress, subject, message, {
    htmlBody: message,
  });
}

function createTriggers() {
  // 先清理所有现有触发器，避免重复冲突
  var existingTriggers = ScriptApp.getProjectTriggers();
  for(var i = 0; i < existingTriggers.length; i++) {
    ScriptApp.deleteTrigger(existingTriggers[i]);
  }

  // 配置需要触发的星期：周日至周四
  var days = [ScriptApp.WeekDay.MONDAY, ScriptApp.WeekDay.TUESDAY,
              ScriptApp.WeekDay.WEDNESDAY, ScriptApp.WeekDay.THURSDAY,                                            
              ScriptApp.WeekDay.SUNDAY];
  for (var i=0; i<days.length; i++) {
    // 修正绑定的函数名
    ScriptApp.newTrigger("sendEmails")
             .timeBased().onWeekDay(days[i])
             .atHour(17).create();
  }
}
