string to ObjectId to use it in my update query, how can I do this?
推荐答案
使用()
如果您有一个代表BSON ObjectId的字符串(例如从Web请求收到),那么您需要将其转换为ObjectId实例:
When you have a string representing a BSON ObjectId (received from a web request for example), then you need to convert it to an ObjectId instance:
const {ObjectId} = require('mongodb'); // or ObjectID
// or var ObjectId = require('mongodb').ObjectId if node version < 6
const updateStuff = (id, doc) => {
// `ObjectId` can throw https://github.com/mongodb/js-bson/blob/0.5/lib/bson/objectid.js#L22-L51, it's better anyway to sanitize the string first
if (!ObjectId.isValid(s)) {
return Promise.reject(new TypeError(`Invalid id: ${id}`));
}
return collection.findOneAndUpdate(
{_id: ObjectId(id)},
{$set: doc},
{returnOriginal: false}
);
};
