Google Drive API Files.List查询字符串-"not"操作员 [英] Google Drive API Files.List Query String - "not" operator

问题描述

类似于此问题 Google Drive API文件.列表查询字符串从某种意义上讲，我想了解setQ方法的所有语法:FileList files = drive.files().list().setQ("trashed = true").setMaxResults(100).execute();

Similar to this question Google Drive API Files.List Query String in the sense that I would like to know all the syntax for the setQ method: FileList files = drive.files().list() .setQ("trashed=true") .setMaxResults(100) .execute();

尤其是我想从查询中获取文件(而不是文件夹).

In particular I would like to get the files (not folders) from the query.

要获取文件夹，此查询将起作用:request.Q = "mimeType='application/vnd.google-apps.folder' and trashed=false "

To get folders this query works: request.Q = "mimeType='application/vnd.google-apps.folder' and trashed=false "

我尝试了不同的组合，例如

I have tried different combinations, like

request.Q = "not mimeType='application/vnd.google-apps.folder' and trashed=false "
request.Q = "mimeType!='application/vnd.google-apps.folder' and trashed=false "

等

有些运行但忽略了，有些只是崩溃.

Some run but ignore the not, some just crash.

是否可以获取仅文件列表?

Is there a way to get a list of only files?
