MongoDB不会保存url字符串

Question

我正试图在Mongo数据库中保存一个对象。我面临的问题是，当我创建模式时，它会保存除img url之外的所有条目。我在创建模式之前记录了url，它成功地打印了它，但当我创建模式对象时，它没有从主体中获得值。

router.post('/', async (req, res) => {
console.log("URL:", req.body.img) //Logs the url successfully
const pet = new Pet({
name: req.body.name,
petType: req.body.petType,
breed: req.body.breed,
age: req.body.age,
img: req.body.img, //i can't get it here
contact: req.body.contact,
location: req.body.location,
userp: req.body.contact,
})
console.log("This is a Pet");
console.log(pet); //logs everything except the "img" field.
try {
const savedPet = await pet.save();
console.log("This pet was saved", savedPet);
res.json(savedPet); //returns an object without the "img" field
} catch (err) {
res.json({ message: err });
}
});

编辑：这也是我的模式文件：

const mongoose = require('mongoose');
const petSchema = mongoose.Schema({
name: {
type: String,
required: false
},
petType: {
type: String,
require: true
},
breed: {
type: String,
require: false
},
age: {
type: Number,
require: false
},
img: {
data: String,
require: false
},
contact: {
type: String,
require: true
},
location: {
type: String,
require: true
},
userp: {
type: String,
require: true
}
});
module.exports = mongoose.model('Pet', petSchema);```

我发现了错误。您可以在此属性中使用data而不是type参数。

img: {
type: String,
require: false
},
