Google Drive API V3如何正确转义查询参数？

Question

Given: working access to Google Drive with some Folders with Space in Name

Problem: The query:

name='07 Dirname' and mimeType='application/vnd.google-apps.folder' and '0B22uLx7BCvv9T0FWRmNaREY4VEE' in parents and trashed=false

does not work over the API, but does if the dir is without space in it. The query does work however if you run it from the API-Explorer which provides as hint: This parameter was URL encoded.

However when I encode the name field with url.QueryEscape or url.PathEscape the folder can not be found. As far as I understand it its not necessary to encode the whole query, just the param, but how?

Thx.

The query needs to be double encoded to work, so call url.QueryEscape first on the search given above and then again on the query string.

If you look at the API Explorer with Chrome devtools, you will see the double encoded values despite the misleading display on the page itself.

e.g. something like https://content.googleapis.com/drive/v3/files?q=name%3D%2707+Dirname%27+and+mimeType%3D%27application%2Fvnd.google-apps.folder%27+and+%270B22uLx7BCvv9T0FWRmNaREY4VEE%27+in+parents+and+trashed%3Dfalse&key={APIKEY}
