Tips

• File upload example (multiple files can be uploaded once as a multipart message):

  curl -X POST -F file=@./img.png http://localhost:8080/v1/nanogw/[Folder]/[Name]

  The uploaded filename is taken from the posted filename. if 'parentId' argument is specified, folder path info is ignored.

• Folder creation example curl -X POST -F folderName='NewFolderName' http://localhost:8080/v1/nanogw/[Folder]/[Name]

  if 'parentId' argument is specified, folder path info is ignored. If no file object is posted, a folder is created under the specified path. In this case, an argument named 'folderName' defines the created folder name (if the name conflicts the existing one, error is returned).

  curl -X POST http://localhost:8080/v1/nanogw/[Folder]/[Name]

  If 'folderName' argument is omitted, the created folder name is identical to the ID.

• GET with 'folderId' argument returns files in folderId. folderId works as a path to folder. In this case, the specified path is ignored.

• Spreadsheet file update example:

  curl -X PUT -d 'values=[["","val1",12345,"12/3"]]' http://localhost:8080/v1/nanogw/[path]/[to]/[spreadsheet] curl -X PUT -F values='[["a","b"]]' -F filename='profile' http://localhost:8080/v1/nanogw/test/people

  • If the path is null (only possible with inside-picogw call), the log file (located at /NanoGW/[mac]/log, if not moved) is updated.

• Google docs file in public folder can be opened by its hash id after

  https://drive.google.com/open?id=

• ffmpeg format conversion

  ffmpeg -i ~/sample.mp3 -f s16le -acodec pcm_s16le -ar 16000 ~/sample.raw
