我在节点App中遇到API路由问题。我切换了Nodemailer的'to'部分,现在突然间它在我的'Post'动作中给了我Async的问题。
我一直收到错误消息:'TypeError:app.post(...)。然后不是函数'
以下是代码:
app.post("/api/applicants", function(req, res) {
db.Applicant.create(req.body);
res.send('Successfully posted new Applicant');
}).then(function(appPost){
//mail details for nodemailer
let mailOptions = {
from: '"noreply@cap.org" <app@cap.org>', // sender address
to: 'ijvv7dth54f7zp3w@ethereal.email', // list of receivers
subject: 'Application Submitted', // Subject line
text: req.body.firstname + ' ' + req.body.last_name + ' just sent you a message!', // plain text body
html: '<b>'+req.body.first_name+'</b>' + '</br>' +
'' + req.body.last_name + '</br>' +
'DOB: '
// html body
};
transporter.sendMail(mailOptions, (error, info) => {
if (error) {
return console.log(error);
}
console.log('Message sent: %s', info.messageId);
// Preview only available when sending through an Ethereal account
console.log('Preview URL: %s', nodemailer.getTestMessageUrl(info));
// Message sent: <b658f8ca-6296-ccf4-8306-87d57a0b4321@blurdybloop.com>
// Preview URL: https://ethereal.email/message/WaQKMgKddxQDoou...
});
});
答案 0 :(得分:1)
您似乎已将.then
承诺处理程序附加到app.post
。 app.post
由Express提供,不返回promise,而是使用处理函数。
看起来你真的希望你的承诺来自db.Applicant.create。在这种情况下,您需要获取.then
承诺并将其放在db.Applicant.create之后。
app.post("/api/applicants", function(req, res) {
return db.Applicant.create(req.body).then(function(appPost){
// Respond to the HTTP request
res.send('Successfully posted new Applicant');
res.end(); // Ensure the response is sent before any emailing is attempted
//mail details for nodemailer
let mailOptions = {
from: '"noreply@cap.org" <app@cap.org>', // sender address
to: 'ijvv7dth54f7zp3w@ethereal.email', // list of receivers
subject: 'Application Submitted', // Subject line
text: req.body.firstname + ' ' + req.body.last_name + ' just sent you a message!', // plain text body
html: '<b>'+req.body.first_name+'</b>' + '</br>' +
'' + req.body.last_name + '</br>' +
'DOB: '
// html body
};
transporter.sendMail(mailOptions, (error, info) => {
if (error) {
return console.log(error);
}
console.log('Message sent: %s', info.messageId);
// Preview only available when sending through an Ethereal account
console.log('Preview URL: %s', nodemailer.getTestMessageUrl(info));
// Message sent: <b658f8ca-6296-ccf4-8306-87d57a0b4321@blurdybloop.com>
// Preview URL: https://ethereal.email/message/WaQKMgKddxQDoou...
});
});
});
在这种情况下,我假设db.Applicant.create
返回一个承诺,但是如果不知道你正在使用的包,就不可能确定。此外,请注意我添加了“res.end()”,它将在尝试电子邮件代码之前关闭HTTP响应,这是可选的,但应确保客户端在处理电子邮件之前获得响应。您可能也可能不想这样做。
