如何解决我想在 google sheet 脚本中为每个循环添加 2 mint 延迟以发送电子邮件,但 setTimeout 和 sleep 不起作用
我希望在一次循环更改后有 2 分钟的延迟。意味着我想在发送电子邮件时添加一些延迟。 完整的代码链接是(https://github.com/googleworkspace/solutions/blob/master/mail-merge/src/Code.js)
obj.forEach(function(row,rowIdx){
sleep(1200000);
// only send emails is email_sent cell is blank and not hidden by filter
if (row[EMAIL_SENT_COL] == ''){
try {
const msgObj = fillInTemplateFromObject_(emailTemplate.message,row);
// @see https://developers.google.com/apps-script/reference/gmail/gmail-app#sendEmail(String,String,Object)
// if you need to send emails with unicode/emoji characters change GmailApp for MailApp
// Uncomment advanced parameters as needed (see docs for limitations)
GmailApp.sendEmail(row[RECIPIENT_COL],msgObj.subject,msgObj.text,{
htmlBody: msgObj.html,// bcc: 'a.bbc@email.com',// cc: 'a.cc@email.com',// from: 'an.alias@email.com',// name: 'name of the sender',// replyTo: 'a.reply@email.com',// noreply: true,// if the email should be sent from a generic no-reply email address (not available to gmail.com users)
attachments: emailTemplate.attachments,inlineImages: emailTemplate.inlineImages
});
// modify cell to record email sent date
out.push([new Date()]);
} catch(e) {
// modify cell to record error
out.push([e.message]);
}
} else {
out.push([row[EMAIL_SENT_COL]]);
}
});
解决方法
解决方案:
您可以使用 Installable Trigger 每分钟运行一次 sendEmails()
。这可以在选择菜单项时创建:
编辑: 由于不允许 everyMinute(2),因此一种解决方法是让函数每分钟执行一次。由于有一个列会在发送电子邮件后更新,因此在第一次执行时,它会将列标记为“要发送”,在第二次执行时,它将发送电子邮件。
function onOpen() {
const ui = SpreadsheetApp.getUi();
ui.createMenu('Mail Merge')
.addItem('Send Emails','createTrigger')
.addToUi();
}
function createTrigger() {
ScriptApp.newTrigger("sendEmails")
.timeBased()
.everyMinutes(1)
.create();
}
然后用一个简单的 for 循环替换 forEach()
,这样一旦第一封电子邮件被标记为发送或发送,它就可以跳出循环。
// loop through the rows of data and break once one email is sent
for (i = 0; i < obj.length; i++) {
var row = obj[i];
// Mark emails with "To Send" if email_sent cell is blank. Only send emails if email_sent cell is "To Send" and not hidden by filter
if (row[EMAIL_SENT_COL] == ''){
out.push(['To Send']);
break;
} else if (row[EMAIL_SENT_COL] == 'To Send'){
try {
const msgObj = fillInTemplateFromObject_(emailTemplate.message,row);
// @see https://developers.google.com/apps-script/reference/gmail/gmail-app#sendEmail(String,String,Object)
// if you need to send emails with unicode/emoji characters change GmailApp for MailApp
// Uncomment advanced parameters as needed (see docs for limitations)
GmailApp.sendEmail(row[RECIPIENT_COL],msgObj.subject,msgObj.text,{
htmlBody: msgObj.html,// bcc: 'a.bbc@email.com',// cc: 'a.cc@email.com',// from: 'an.alias@email.com',// name: 'name of the sender',// replyTo: 'a.reply@email.com',// noReply: true,// if the email should be sent from a generic no-reply email address (not available to gmail.com users)
attachments: emailTemplate.attachments,inlineImages: emailTemplate.inlineImages
});
// modify cell to record email sent date
out.push([new Date()]);
} catch(e) {
// modify cell to record error
out.push([e.message]);
}
break;
} else {
out.push([row[EMAIL_SENT_COL]]);
}
}
一旦处理完所有的行,删除触发器:
// updating the sheet with new data
sheet.getRange(2,emailSentColIdx+1,out.length).setValues(out);
if (out.length == obj.length) {
var triggers = ScriptApp.getProjectTriggers();
for (var j = 0; j < triggers.length; j++) {
ScriptApp.deleteTrigger(triggers[j]);
}
}
