How do to access files using folder Id

Just having a difficult time figuring how to access files in folders using Googles Drive RESP API v3.

I know I can access files using the /children in v2 of REST API

GET https://www.googleapis.com/drive/v2/files/folderId/children

According to migration notes for v3 of REST API

Duplicate and obsolete functionality has been removed. Examples:

  • The Children and Parents collections have been removed. Use files.list instead.

From what I can gather children.list was a function you could leverage if you used gapi.js

request = gapi.client.drive.children.list({
  'folderId' : folderId,
  'pageToken': nextPageToken
});

Again, following the notes children.list should be substituted for files.list with ?q='parent_id'+in+parents.

But what does that actually mean for REST API users?

GET https://www.googleapis.com/drive/v3/files?q={folderId}+in+parents
GET https://www.googleapis.com/drive/v3/files?q=parents(folderId)
GET https://www.googleapis.com/drive/v3/files?q=folderId

No matter what I try I just keep getting 400 error - invalid value in the q.

The format is

https://content.googleapis.com/drive/v3/files?q=%270Bw3h_yCVtXbbQ2VEQkRNQ0J1YTg%27%20in%20parents

Note the single quote (%27) around the folder ID.

How about this modification?

I don't know whether I can understand your question. If I misunderstand your question, I'm sorry.

I think that q='parent_id'+in+parents you use is correct. It means that a file list in the parent_id is retrieved. But when I see your tested endpoint and query, there is a modification point that I thought that this might be the reason of error.

From :

GET https://www.googleapis.com/drive/v3/files?q={folderId}+in+parents

To :

GET https://www.googleapis.com/drive/v3/files?q='{folderId}'+in+parents

About error message :

When I tried to run it without the single quotes, the following error was retrieved. So I thought that this might be the reason.

{
 "error": {
  "errors": [
   {
    "domain": "global",
    "reason": "invalid",
    "message": "Invalid Value",
    "locationType": "parameter",
    "location": "q"
   }
  ],
  "code": 400,
  "message": "Invalid Value"
 }
}

Reference :

If you have already used the single quotes in {folderId}, and if this was not useful for you, I'm sorry.
