Email METEOR:无法向多个用户发送电子邮件

当我有新帖子时，我需要通过他们的电子邮件通知所有用户

server/methods.js

Meteor.methods({
  sendNewsletter: function(doc) {
    var pipeline = [
      {$group: {_id:"$emails.address"}}
    ];
    var to = Meteor.users.aggregate(pipeline);
    var text = "Title: " + doc.title + "\n\n"
            + "Summary: " + doc.summary + "\n\n\n\n"

    this.unblock();

    // Send the e-mail
    Email.send({
        to: to,
        from: "noreply@domain.com",
        subject: "MyApp - " + doc.title,
        text: text
    });
  }
});

在客户端调用sendNewsletter的方法时，我在终端上收到以下警告：

有人知道如何向多个收件人发送电子邮件吗？谢谢，，，，

重新编写

服务器/methods.js

文件获取

to

变量以保存电子邮件地址数组。 由于Meteor不支持MongoDB中的distinct（尚未），您只需在MongoShell中使用它作为

db.users.distinct（“emails.address”）

，就可以了

使用underline.js库、和中的三种方法从用户集合中获取不同的电子邮件地址

首先在光标上使用将返回的流星光标转换为数组。例如：

var users = Users.find({}, { fields: {"emails": true} }).fetch();   

然后使用方法通过转换函数（iteratee）映射列表中的每个文档，在另一个数组中生成一个仅包含电子邮件地址值的新数组。定义转换函数如下

var callback = function(doc) {
    var emailAddresses = [];
    for (var i = 0; i < doc.emails.length; i++) {
        emailAddresses.push(doc.emails[i].address);
    }
    return emailAddresses;
};

var emails = _.map(users, callback);

通过使用来展平阵列，以获得可用的阵列，然后使用方法返回一组独特的阵列，如下所示：

var uniqueEmails = _.uniq(_.flatten(emails));

总之，您的代码现在应该有一个电子邮件地址数组，然后可以发送

Meteor.methods({
    sendNewsletter: function(doc) {
        var users = Users.find({}, { fields: {"emails": true} }).fetch();
        var callback = function(doc) {
            var emailAddresses = [];
            for (var i = 0; i < doc.emails.length; i++) {
                emailAddresses.push(doc.emails[i].address);
            }
            return emailAddresses;
        };

        var emails = _.map(users, callback);
        var to = _.uniq(_.flatten(emails));
        var text = "Title: " + doc.title + "\n\n"
                + "Summary: " + doc.summary + "\n\n\n\n"

        this.unblock();

        // Send the e-mail
        Email.send({
            to: to,
            from: "noreply@domain.com",
            subject: "MyApp - " + doc.title,
            text: text
        });
    }
});

Meteor.methods({
发送通讯：功能（文档）{
var users=users.find（{}，{字段：{“emails”：true}}）.fetch（）；
var callback=函数（doc）{
var emailAddresses=[]；
对于（var i=0；i

查看下面的演示

var用户=[
{
“_id”：“UKN9MLO3版权所有”，
“电子邮件”：[
{
“地址”：a@a.com",
“已验证”：错误
}
]
},
{
“_id”：“5SXRXRXRARIYHRQACE”，
“电子邮件”：[
{
“地址”：b@a.com",
“已验证”：错误
}
]
},
{
“_id”：“WMHWxeymY4ATWLXjz”，
“电子邮件”：[
{
“地址”：c@a.com",
“已验证”：错误
}
]
}
];
var callback=函数（d）{
var emailAddresses=[]；
对于（var i=0；i

hi@MichelFloyd。。是的，这就是问题所在。我已经问了这个问题的解决办法：你说的带逗号的字符串是什么意思？哦，没关系。调用“字符串或字符串数组”，这样您就走上了正确的轨道。@KarinaL不用担心，乐意帮助。
Meteor.methods({
    sendNewsletter: function(doc) {
        var users = Users.find({}, { fields: {"emails": true} }).fetch();
        var callback = function(doc) {
            var emailAddresses = [];
            for (var i = 0; i < doc.emails.length; i++) {
                emailAddresses.push(doc.emails[i].address);
            }
            return emailAddresses;
        };

        var emails = _.map(users, callback);
        var to = _.uniq(_.flatten(emails));
        var text = "Title: " + doc.title + "\n\n"
                + "Summary: " + doc.summary + "\n\n\n\n"

        this.unblock();

        // Send the e-mail
        Email.send({
            to: to,
            from: "noreply@domain.com",
            subject: "MyApp - " + doc.title,
            text: text
        });
    }
});
