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?
如果taskId和name是查询参数,则url变为
url/doSomething/?taskId=123&name=name
For this url: url/doSomething/taskId
, you do something like this:
{
name: "the_name_you_want"
}
Inside of Postman.
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
