通过邮递员更新猫鼬

Question

In my mongoose controller, I have something like:

exports.update_a_task = function(req, res) {
  Task.findOneAndUpdate({_id: req.params.taskId}, req.body, {new: true}, function(err, task) {
    if (err)
      res.send(err);
    res.json(task);
  });
};

And in my PUT command in Postman I put:

url/doSomething/taskId/name //or ,name

But it would only prompt a CastError. How should the URL look like if I want to update a document using the PUT command?

Answer 1

如果taskId和name是查询参数，则url变为

url/doSomething/?taskId=123&name=name

Answer 2

For this url: url/doSomething/taskId , you do something like this:

{
  name: "the_name_you_want"
}

Inside of Postman.

Answer 3

To get it in mongoose you need to have the url like this url/doSomething/:taskId/:name

then in postman you can do a put request to url/doSomething/taskId/name now you can use req.params.taskId

if you want to supply the data as /url/doSomething?taskId=&name= you would need to use req.query.taskId
