Javascript 解析云代码Mandrill承诺

因此，我在迁移Mailgun并开始使用Mandrill时遇到了一个问题。我遵循了Parse Purchase应用程序教程，并且有一个非常类似的代码库。以下是它当前的状态并成功运行

return Mailgun.sendEmail({
    to: currentUser.get('email'),
    from: hostEmail,
    subject: 'Your ticket(s) purchase for ' + eventObject.get('title') + ' was successful!',
    text: body
}).then(null, function(error) {
    return Parse.Promise.error('Your purchase was successful, but we were not able to send you an email.');
});

因此，这将成功运行，不会引发任何错误

这就是山楂的等价物

return Mandrill.sendEmail({
    message: {
        text: body,
        subject: 'Your ticket(s) purchase for ' + eventObject.get('title') + ' was successful!',
        from_email: hostEmail,
        from_name: appname,
        to: [{
            email: currentUser.get('email'),
            name: currentUser.get('displayName')
        }]
    },
    async: true
}).then(null, function(error) {
    console.log('Sending email failed. Error: ' + error);
    return Parse.Promise.error('Your purchase was successful, but we were not able to send you an email.');
});

显然，这是行不通的

错误日志显示：

Error: TypeError: Cannot read property 'success' of undefined
at Object.exports.sendEmail (mandrill.js:55:21)
at main.js:115:25
at e (Parse.js:2:6670)
at Parse.js:2:6119
at Array.forEach (native)
at Object.x.each.x.forEach [as _arrayEach] (Parse.js:1:661)

at Parse.js:2:6749
at e (Parse.js:2:6670)
at Parse.js:2:6119 (Code: 141, Version: 1.6.0)

因此，我认为Mandrill成功发送电子邮件是因为它搜索了“success”属性，但承诺总是失败，并将错误响应返回到iOS应用程序

任何帮助都将不胜感激

再次感谢

找到了问题。显然，您必须实际声明一个promise变量并将成功/失败回调发送给它

我在评论中发布的要点链接帮助了我

这就是我现在要做的

Parse.Cloud.define('purchase', function(request, response) { 
    ...

    ...

    ...

    var message = {
            text: body,
            subject: 'Your ticket(s) purchase for ' + eventObject.get('title') + ' was successful!',
            from_email: hostEmail,
            from_name: appname,
            to: [{
                email: currentUser.get('email'),
                name: currentUser.get('displayName'),
            }]
        };

    return sendMandrillEmailPromise(message).then(null, function(error) {
        console.log('Sending email failed. Error: ' + error);
        return Parse.Promise.error('Your purchase was successful, but we not able to send you an email');
    ...

    ...

    ...  
});

var sendMandrillEmailPromise = function(message){
    var promise = new Parse.Promise();
    Mandrill.sendEmail({
        message: message,
        async: true,
    },{
        success: function(httpResponse) {
            promise.resolve(httpResponse);
        },
        error: function(error) {
            promise.error(error);
        }
    });
    return promise;
}

工作如预期，我收到了一封很棒的电子邮件！谢谢大家的意见

你确定Mandrill支持承诺吗？它似乎在寻找

成功

回调。您真的想要

异步：false

？@Bergi不，我不想要。那是我的错，哈哈。这将基本上停止整个服务器，直到进程完成。那太糟糕了！是这样吗？他们为什么要给我们这个选择？@Bergi，我在这里找到了一个链接，将承诺与Mandrill sendMail集成在一起。我会发布一个editAh好吧，我认为这是一个答案，而不是一个编辑…你可能想向Mandrill提交一份bug报告，当然，他们是否会支持开箱即用的承诺：-）听起来像是一个计划！行
