节点 rest API：放置请求未更新请求数据

Question

Trying to update data using PUT request. But, the data is not updating and returning the previous data in postman.

Postman put request:

http://localhost:3000/api/actors/5daa8f1c5845ad0b5826b8d9?name=Tom

Postman response:

{
    "createdAt": "2019-10-19T04:16:13.317Z",
    "updatedAt": "2019-10-19T04:16:13.317Z",
    "_id": "5daa8f1c5845ad0b5826b8d9",
    "name": "scarlett johansson",
    "birthday": "1980-10-14T00:00:00.000Z",
    "country": "usa",
    "__v": 0
}

I have also tried to use findByIdAndUpdate. Didn't get the result. Any help would be appreciated.

Controller:

exports.updateActor = async(req, res, next) => {
    try {
        const actorId = req.params.actorId;
        const data    = req.body;

        const updateActor = await Actor.findById(actorId);

        updateActor.set(data);

        const actor = await updateActor.save();

        // res.status(200).json({ message: "Data has Updated Successfully!" });
        res.send(actor);

    } catch (err) {
        res.status(500).json({ message: err.message });
    }
};

Router:

router.put('/actors/:actorId', Actor.updateActor);

Answer 1

Your postman request is http://localhost:3000/api/actors/5daa8f1c5845ad0b5826b8d9?name=Tom so look like the data to update will be in req.query instead of req.body .

Note : You should put the data to update in the body instead of query like you're doing.

Answer 2

Please use following code for getting update data 

 Actor.findOneAndUpdate({"_id":ObjectId(actorId)},data, 
 { new: true}).then((updatedData) => {
 res.send(updatedData);
 });

Answer 3

To resolve the ObjectId error use the below code.

var mongoose = require('mongoose');
const updateActor = await Actor.findOneAndUpdate({"_id":mongoose.Types.ObjectId(actorId)},data, { new: true });
res.send(updateActor);

Answer 4

exports.updateActor = async(req, res, next) => {
    try {
        const actorId = req.params.actorId;
        const data    = req.body;

        const updateActor = await Actor.update({"_id":actorId},data);


        // res.status(200).json({ message: "Data has Updated Successfully!" });
        res.send(updateActor);

    } catch (err) {
        res.status(500).json({ message: err.message });
    }
};
