我使用SendGrid和Firebase函数向多个收件人发送多封电子邮件。我使用的代码在发送到4个电子邮件地址的测试列表时可以正常工作，但在尝试发送到4000个电子邮件地址时不起作用。SendGrid也没有错误消息。
如果SendGrid代码块被注释掉，此代码也可以工作并返回控制台中打印的电子邮件地址列表。你知道可能出了什么问题吗？
谢谢
exports.adminSendGroupMessage = functions.region('europe-west2').https.onCall((data, context) => {
const emailHTMLData = emailHTMLData;
var emailDataArray = [];
//Fetch contacts list
let testContactsRef = db.collection('contacts-list');
return testContactsRef.get().then(snapshot => {
snapshot.forEach(doc => {
// console.log(doc.id, '=>', doc.data());
console.log("Fetched contact with ID: " + doc.id);
//Extract contact data
const firstName = doc.data().name || "";
const surname = doc.data().surname || "";
const emailAddress = doc.data().emailAddress;
var emailData = {
to: emailAddress,
from: 'fromEmail@email.com',
subject: messageSubject,
text: 'Email for ' + firstName,
html: emailHTMLData,
customArgs: {
ref: 'msg-ref'
},
}
//Add new email data to the array
emailDataArray.push(emailData);
});
return Promise.all(emailDataArray).then(results => {
//Send emails with all data once contact fetch complete
console.log("Success fetching contacts - send emails.");
sendGridGroupMessages(emailDataArray);
return { success : true, message: "Success sending emails" };
})
});
function sendGridGroupMessages(emailDataArray) {
console.log('Send emails to group function with data: ' + emailDataArray.length);
var i,j, splitArray,chunk = 998;
for (i=0,j=emailDataArray.length; i<j; i+=chunk) {
splitArray = emailDataArray.slice(i,i+chunk);
// do whatever
//Send emails
sgMail.send(splitArray, (error, result) => {
if (error) {
//Do something with the error
console.log("Error sending group emails: " + error);
// throw new functions.https.HttpsError('internal', 'There was an error sending the group emails - ' + error.message + ' (' + error.code + ')');
} else {
//Celebrate
console.log("Success sending group emials: " + JSON.stringify(result));
// return { success : true };
}
});
}
您必须发布错误日志如果没有错误，则表示他们发送了但是查看SendGrid活动，看看这些电子邮件发生了什么
