使用云功能在firestore上创建用户时发送电子邮件

Question

我试图在我的flutter应用程序上创建用户后发送电子邮件验证链接，但电子邮件没有发送，在我的云函数日志中，我在部署时收到消息：

{@type:“type.googleapis.com/google.cloud.audit.AuditLog”，“status:{”code:“9”，“message:“FAILED_premission”}，“authenticationInfo:{”principalEmail:“**********************”}，”requestMetadata:{”callerIp:“186.216.140.62”，“callerSuppliedUserAgent:“FirebaseCLI/6.5.0，gzip（gfe），gzip（gfe）”，“requestAttributes:{”time:“2019-03-29T23:21:10.130Z”，“auth:{，“destinationAttributes”：{}}，“serviceName”：“cloudfunctions.googleapis.com”，“methodName”：“google.cloud.functions.v1.CloudFunctionsService.UpdateFunction”，“authorizationInfo:[{“权限”：“cloudfunctions.functions.update”，“已授予”：true，“resourceAttributes”：{}}，{“资源”：“projects/pppppppp-9800a/locations/us-central1/functions/sendVerificationEmail”，“权限”：“cloudfunctions.functions.update”，“已授予”：true，“resourceAttributes”：{}]，“resourceName”：“projects/pppppp-9800a/locations/us-central1/functions/sendVerificationEmail”，“request”：{“@type”：“type.googleapis.com/google.cloud.functions.v1.UpdateFunctionRequest”，“function”：{“labels”：{“deployment tool”：“cli firebase”}，“eventTrigger”：{“eventType”：“providers/cloud.firestore/eventTypes/document.create”，“resource”：“projects/pppppp-9800a/databases/（default）/documents/users/{userId}”，“service”：“firestore.googleapis.com”}，“sourceUploadUrl”：”https://storage.googleapis.com/gcf-upload-us-central1-dc1829cf-3a07-4951-be81-1a15f892ed8d/8ea3f162-c860-4846-9064-04a855efca2f.zip?GoogleAccessId=service-73683634264@gcf-管理员机器人。国际机械师协会。gserviceaccount。通用域名格式

我的代码：

exports.sendVerificationEmail = functions.firestore.document('users/{userId}').onCreate((snap, context) => {
  const user = snap.data();
  console.log("----------------------");
  console.log("user created: " + user.uidColumn);
  admin.auth().generateEmailVerificationLink(user.email).then((link) => {
    console.log("**********" + link);
    sendVerificationEmail(user.emailColumn, link);
    return 0;
  }).catch(e => {
    console.log(e);
  })
  return 0;
});

function sendVerificationEmail(email, link) {
  var smtpConfig = {
    host: 'smtp.gmail.com',
    port: 465,
    secure: true, // use SSL
    auth: {
      user: '[e-mail]',
      pass: 'password'
    }
  };

  var transporter = nodemailer.createTransport(smtpConfig);

  var mailOptions = {
    from: "[e-mail]", // sender address
    to: email, // list of receivers
    subject: "Email verification", // Subject line
    text: "Email verification, press here to verify your email: " + link,
    html: "<b>Hello there,<br> click <a href=" + link + "> here to verify</a></b>" // html body
  };

  transporter.sendMail(mailOptions, function (error, response) {

    if (error) {
      console.log(error);
    } else {
      console.log("Message sent: " + response.message);
    }
    return 0;
  });
  return 0;
}

当我使用命令firebase deploy时，我收到消息functions:failed to update function sendVerificationEmail HTTP Error:400，不允许更改函数触发器类型或事件提供程序

我是新来的，我不知道这些错误是什么意思

Answer 1

删除第一个名为sendVerizationEmail的函数，然后重新部署。看起来你可能最初把它部署成了除了火力恢复触发器之外的东西。
