如何找到用户的帖子？

Question

你好，我想找到用户所做的帖子...

我使用JWT令牌执行请求：

###
http://localhost:8080/forum/getByOwnerID
Authorization: Bearer {{token}}

这是我的创建函数：

exports.create = async (req, res) => {
 
  const { forumName, forumDescription } = req.body;
  const token = req.token;
  const forumExist = await Forum.findOne({ forumName: req.body.forumName });
  if(forumExist){
    res.status(400).send("Forum Exists already.");
  }  
  try{
  const owner = await User.findOne({userID:token._id});
  if (!forumName || !forumDescription) {
    res.status(400);
    throw new Error("Please Fill all the feilds");
    return;
  }
  else {
    const newForum = new Forum({ forumName, forumDescription,user: owner.userID });
    newForum.user = owner;
    const createdNote = await newForum.save();
    res.status(201).json(createdNote);
  }
  }catch(err){
    res.status(400).send(err);
  }
};

这是我的函数，我想在其中获取用户发表的帖子：

exports.getByToken = async (req, res, next) => {
  const forum = await Forum.findById( {user: req.token._id} );

  if (forum) {
    res.json(forum);
  } else {
    res.status(404).json({ message: "Forum not found" });
  }

  res.json(forum);
}

这是我为博文准备的模型：

const forumSchema = ({
    forumName: {
        type: String,
        required: true,
    },
    forumDescription: {
        type: String,
        required: true,
    },
    user: { 
        type: Schema.Types.ObjectId,
        
        ref: 'user'
    },
    published_on: {
        type: String,
        default: moment().format("LLL")
    },
});

每次我做一个请求它有这个错误：

UnhandledPromiseRejectionWarning: CastError: Cast to ObjectId failed for value "{ user: 'admin' }" (type Object) at path "_id" for model "Forum"

我的生成令牌：

const generateToken = (_id, userID) => {
  console.log('Signing token for ID ', _id,userID);
  console.log('Secret key is ', process.env.JWT_KEY);
  const token = jwt.sign({ _id,userID}, process.env.JWT_KEY, {
    expiresIn: "30d",
  });
  console.log('Signed token: ', token);
  return token;
  
};

在使用findById时，只应将id作为参数函数发送。

如果你想搜索过滤器查询，使用查找方法
