問題描述

我想使用 Python 獲取 Google Drive 中給定文件夾中所有文件/文件夾的列表.我正在使用的電話是這樣的:

I want to use Python to get a list of all the files/folders in a given folder in Google Drive. The call I'm using is this:

query = parentID + " in parents"

response = service.files().list(q=query,
                                spaces='drive',
                                fields='files(id, name, parents)').execute()

根據搜索文件文檔和遷移到 v3 文檔，我應該做的正確.但是當我運行代碼時，出現以下錯誤:

According to the search for files documentation and the migrating to v3 documentation, I should be doing it correctly. But when I run the code, I get the following error:

<HttpError 400 when requesting https://www.googleapis.com/drive/v3/files?q=[MY_PARENT_ID]+in+parents&spaces=drive&alt=json&fields=files%28id%2C+name%2C+parents%29 returned "Invalid Value">

我的查詢出了什么問題，我該如何正確調用它?

What is wrong with my query and how would I call this correctly?

推薦答案

試了15個小時，找到了這個解決方案:

After trying for some 15 hours, found this solution:

只需改變 query 變量如下假設父 id 是 '0B_hg54vjh34v5jh23gv5i2v35th2gv35v235kjvk'

just change the query variable as follows suppose parent id is '0B_hg54vjh34v5jh23gv5i2v35th2gv35v235kjvk'

query="'0B_hg54vjh34v5jh23gv5i2v35th2gv35v235kjvk' in parents"

現在，它應該可以工作了.

now, it should work.

即使你交換單引號和雙引號它也應該工作..你使用的結果是 query="0B_hg54vjh34v5jh23gv5i2v35th2gv35v235kjvk in parents" 而我們需要的是 query="'0B_hg54vjh34v5jh23gv5i2v35th2gv35v235kjvk'在父母中"

it should work even if you interchange single and double quotes..what you were using results into query="0B_hg54vjh34v5jh23gv5i2v35th2gv35v235kjvk in parents" while what we need is query="'0B_hg54vjh34v5jh23gv5i2v35th2gv35v235kjvk' in parents"

另一種做法是:

parentId='0B_hg54vjh34v5jh23gv5i2v35th2gv35v235kjvk'
query="'" + "' in parents"

為什么會這樣:-
如果您正確查看輸出錯誤，它有一個如下所示的 http 鏈接:
https://www.googleapis.com/drive/v3/files?q=0B_hg54vjh34v5jh23gv5i2v35th2gv35v235kjvk+in+parents&spaces=drive&alt=json&fields=files%28id%2C+name%2C+parents%29

但所需的 Id 周圍有單引號，如下所示:
https://www.googleapis.com/drive/v3/files?q='0B_hg54vjh34v5jh23gv5i2v35th2gv35v235kjvk'+in+parents&spaces=drive&alt=json&fields=files%28id%2C+name%2C+parents%29
