My Appointments</h4><table id="appointments" class="table"><tr><th>First name</th><th>Last name</th><th>Email</th><th>Service</th></tr>`;

for (let appointment of data) {
tableString += `<tr><td>${appointment.firstName}</td><td>${appointment.lastName}</td><td>${appointment.email}</td><td>${appointment.service}</td></tr>`;
}

tableString += `</table>`;

document.getElementById('appointments').innerHTML = tableString;
});

看起来您使用的是Appointment模型对象，而不是约会文档。试试这个：

app.get('/api/appointments/:email', async(req, res, next) => {
Appointment.find({'email': req.params.email}, function(err, appointments) {
if (err) {
console.log(err);
next(err);
} else {
// Respond with the appointments documents instead of the Appointment model
res.json(appointments);
}
})
})
