使用GridFSBucket删除.file和.chunk

Question

我正在尝试同时删除.files和.chunk数据，但是我发现的所有帖子都已过时或不适用于我的问题。

这是我的后端路线：

const mongoose = require("mongoose");
const config = require("config");
const db = config.get("mongoURI");
let gfs;
const conn = mongoose.createConnection(db);
conn.once("open", () => {
  gfs = new mongoose.mongo.GridFSBucket(conn.db, {
    bucketName: "photos"
  });
});

router.delete('/:imageID', async (req, res) => {
    gfs.delete({_id: req.params.imageID, root:"photos"}, function(error){
      test.equal(error, null);
}

有什么想法吗？

已解决！要成功删除GridFS .files和.chunks，只需找到obj_id并执行gfs.delete( obj_id)代码：

router.delete("/:imageID", auth, async (req, res) => {
  try {
    const post = await Post.findOne({ image: req.params.imageID });
    console.log(post);
    if (post.user != req.user.id) {
      res.status(401).send("Invalid credentials");
    }

// Here:
    const obj_id = new mongoose.Types.ObjectId(req.params.imageID);
    gfs.delete( obj_id );

    await post.remove();
    res.json("successfully deleted image!");
  } catch (err) {
    console.error(err.message);
    res.status(500).send("Server Error");
  }
});
