为什么Google API V3无法返回子级? [英] Why Won't Google API V3 Return Children?

问题描述

我想使用Python获取Google云端硬盘中给定文件夹中所有文件/文件夹的列表.我正在使用的电话是这样:

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()

根据搜索文件文档和迁移到v3 文档，我应该做的正确.但是，当我运行代码时，出现以下错误:

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">

我的查询出了什么问题?我如何正确地称呼它?

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

推荐答案

尝试了15个小时后，找到了以下解决方案:

After trying for some 15 hours, found this solution:

只需更改 query 变量，如下所示假设父ID为'0B_hg54vjh34v5jh23gv5i2v35th2gv35v235kjvk'

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

query="'0B_hg54vjh34v5jh23gv5i2v35th2gv35v235kjvk' in parents"

现在，它应该可以工作了.

now, it should work.

即使您将单引号和双引号互换，它也应该起作用..您正在将结果用于 query ="0B_hg54vjh34v5jh23gv5i2v35th2gv35v235kjvk(在父母中)使用，而我们需要的是 query ="'0B_hg54vjh34v5jh23g'35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"

替代方法是:

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

为什么会这样:-
如果您正确查看输出错误，它具有如下所示的http链接:
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在ID周围加上单引号，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+％29
