Firebase Firestore云函数:无法读取属性';用户ID';未定义的
我无法从云功能发送欢迎电子邮件。每当在我的firestore中使用路径为Users/userId的“Users”集合创建新用户时Firebase Firestore云函数:无法读取属性';用户ID';未定义的,firebase,cloud,google-cloud-firestore,google-cloud-functions,Firebase,Cloud,Google Cloud Firestore,Google Cloud Functions,我无法从云功能发送欢迎电子邮件。每当在我的firestore中使用路径为Users/userId的“Users”集合创建新用户时 exports.welcomeEmail = functions.firestore.document('Users/{userId}') .onCreate((snap, context)=>{ const userId = context.params.userId; const db = admin.firestore()
exports.welcomeEmail = functions.firestore.document('Users/{userId}')
.onCreate((snap, context)=>{
const userId = context.params.userId;
const db = admin.firestore()
return db.collection('Users').doc(userId)
.get()
.then(doc => {
const user = doc.data()
const msg = {
to: user.email,
from: 'cybertronjc3@gmail.com',
subject: 'Welcome to COFOZ',
templateId: '1c455865-4529-4ae1-8e5a-9a5b8eaf0157',
substitutionsWrappers: ['{{', '}}'],
substitutions: {
name: user.name
}
};
return sgMail.send(msg)
})
.then(() => console.log('email sent!'))
.catch(err => console.log(err))
})
这就是我得到的错误

您可能正在使用旧版本的云功能SDK。您可以检查“依赖项”节点下的package.json
文件中使用的版本吗
根据代码中使用的语法,应该有一个等于或高于1.0.0的版本
有关更多信息,请参阅此文档(迁移指南):并检查package.json文件中的版本
您将看到,要更新到新SDK,您应该执行以下操作:
npm安装firebase-functions@latest--保存
npm安装firebase-admin@5.11.0--保存
无需通过在文档中查找userid来获取新用户。只需从snap获取新创建的文档
exports.welcomeEmail = functions.firestore.document('Users/{userId}')
.onCreate((snap, context)=>{
const user = snap.data();
const msg = {
to: user.email,
from: 'cybertronjc3@gmail.com',
subject: 'Welcome to COFOZ',
templateId: '1c455865-4529-4ae1-8e5a-9a5b8eaf0157',
substitutionsWrappers: ['{{', '}}'],
substitutions: {
name: user.name
}
return sgMail.send(msg)
}
