我有一个联系表单,用于向Firestore数据库提交数据。我的意图是,只要在requests
集合中有另一个条目,Firestore就会通过Cloud Function触发一个函数,它包含SendGrid的配置,SendGrid也应该将此特定条目的数据发送到电子邮件。
我也试过部署这个功能,但这个功能很成功 - 但控制台显示以下错误,我认为这不是唯一的错误:
无法读取未定义的属性'requestId'
const functions = require('firebase-functions');
const admin = require('firebase-admin');
admin.initializeApp();
const SENDGRID_API_KEY = functions.config().sendgrid.key;
const sgMail = require('@sendgrid/mail');
sgMail.setApiKey(SENDGRID_API_KEY);
exports.firestoreEmail = functions.firestore
.document('requests/{requestId}')
.onCreate(event => {
const requestId = event.params.requestId;
const db = admin.firestore();
return db.collection('requests').doc(requestId)
.get()
.then(doc => {
const requestId = event.params.requestId;
const request = doc.data();
const msg = {
to: '[email protected]',
from: '[email protected]',
templateId: 'd-',
substitutionWrappers: ['{{', '}}'],
substitutions: {
name: request.name,
lastname: request.lastname,
email: request.email,
package: request.package,
date: request.date,
text: request.text
// and other custom properties here
}
};
return sgMail.send(msg)
})
.then(() => console.log('email sent!') )
.catch(err => console.log(err) )
});
编辑:
const functions = require('firebase-functions');
const admin = require('firebase-admin');
admin.initializeApp();
const SENDGRID_API_KEY = functions.config().sendgrid.key;
const sgMail = require('@sendgrid/mail');
sgMail.setApiKey(SENDGRID_API_KEY);
exports.request = functions.firestore
.document('requests/{requestId}')
.onCreate((snap, context) => {
const db = admin.firestore();
return db.collection('requests').doc(requestId)
.get()
.then(doc => {
const requestId = snap.id;
const request = doc.data();
const msg = {
to: '[email protected]',
from: '[email protected]',
templateId: 'd-3cd6b40ad6674f33702107d2',
substitutionWrappers: ['{{', '}}'],
substitutions: {
name: request.name,
lastname: request.lastname,
email: request.email,
package: request.package,
date: request.date,
text: request.text
// and other custom properties here
}
};
return sgMail.send(msg)
})
.then(() => console.log('email sent!') )
.catch(err => console.log(err) )
});
.onCreate()
方法不返回event
,它返回对象的快照,并从中获取新对象的id。
所以在你的情况下,它必须是:
exports.firestoreEmail = functions.firestore.document('requests/{requestId}')
.onCreate((snap, context) => {
const requestId = snap.id; // get the id
const db = admin.firestore();
return db.collection('requests').doc(requestId)
.get()
.then(doc => {
const request = doc.data();
const msg = {
to: '[email protected]',
from: '[email protected]',
templateId: 'd-3cd6b40ad6674f33702107d2',
substitutionWrappers: ['{{', '}}'],
substitutions: {
name: request.name,
lastname: request.lastname,
email: request.email,
package: request.package,
date: request.date,
text: request.text
// and other custom properties here
}
};
return sgMail.send(msg)
})
.then(() => console.log('email sent!') )
.catch(err => console.log(err) )
});
