Pydrive错误：没有在元数据中找到的mimetype的downloadLink / exportLinks

Question

我正在尝试使用pydrive模块自动从谷歌驱动器下载一个简单的文本文件。我一直收到以下错误：

  

追踪（最近一次通话）：     文件＆＃34; C：\ GIS \ AVGOPS \ Scripts \ GoogleDrive_Test.py＆＃34;，第20行，在       item.GetContentFile（r＆＃39; C：\ Users \ pfilyer \ Desktop \ googedrive \＆＃39; + item [＆＃39; title＆＃39;]）     GetContentFile中的文件＆＃34; C：\ Python27 \ ArcGIS10.4 \ lib \ site-packages \ pydrive \ files.py＆＃34;，第210行       self.FetchContent（mimetype，remove_bom）     文件＆＃34; C：\ Python27 \ ArcGIS10.4 \ lib \ site-packages \ pydrive \ files.py＆＃34;，第43行，_decorated       return decoratee（self，* args，** kwargs）     文件＆＃34; C：\ Python27 \ ArcGIS10.4 \ lib \ site-packages \ pydrive \ files.py＆＃34;，第265行，在FetchContent中       ＆＃39;没有在元数据中找到的mimetype的downloadLink / exportLinks＆＃39;）   FileNotDownloadableError：没有在元数据中找到的mimetype的downloadLink / exportLinks

有什么建议吗？

import pydrive
from pydrive.drive import GoogleDrive

from pydrive.auth import GoogleAuth

gauth = GoogleAuth()
gauth.LoadCredentialsFile(r"C:\Users\XXXXX\.credentials\drive-python-quickstart.json")
drive = GoogleDrive(gauth)

print "Auth Success"

folder_id = '0BxbuUXtrs7adSFFYMG0zS3VZNFE'
lister = drive.ListFile({'q': "'%s' in parents" % folder_id}).GetList()
for item in lister:
    print item['title']
    item.GetContentFile(r'C:\Users\XXXXX\Desktop\googedrive\\' +    item['title'])

您可能正在尝试下载Google文档，电子表格或其他不是普通文件的内容。

我刚刚尝试下载mimeType：application / vnd.google-apps.document文件时出现了完全相同的错误。在下载之前，必须将文档导出为其他格式。 检查一下：

import pydrive
from pydrive.drive import GoogleDrive

from pydrive.auth import GoogleAuth

gauth = GoogleAuth()
gauth.LoadCredentialsFile(r"C:\Users\XXXXX\.credentials\drive-python-    quickstart.json")
drive = GoogleDrive(gauth)

print "Auth Success"

folder_id = '0BxbuUXtrs7adSFFYMG0zS3VZNFE'
lister = drive.ListFile({'q': "'%s' in parents" % folder_id}).GetList()
for item in lister:
    print(item['title'])
    # this should tell you which mimetype the file you're trying to download 
    # has. 
    print('title: %s, mimeType: %s' % (item['title'], item['mimeType']))
    mimetypes = {
        # Drive Document files as PDF
        'application/vnd.google-apps.document': 'application/pdf',

        # Drive Sheets files as MS Excel files.
        'application/vnd.google-apps.spreadsheet': 'application/vnd.openxmlformats-officedocument.spreadsheetml.sheet'

    # see https://developers.google.com/drive/v3/web/mime-types
    }
    download_mimetype = None
    if file['mimeType'] in mimetypes:
        download_mimetype = mimetypes[file['mimeType']]
        file.GetContentFile(file['title'], mimetype=download_mimetype)

        item.GetContentFile(r'C:\Users\XXXXX\Desktop\googedrive\\' + item['title'], mimetype=download_mimetype)
    else: 
        item.GetContentFile(r'C:\Users\XXXXX\Desktop\googedrive\\' + item['title'])

这应该有效。

将文档上传到Google驱动器时，请确保在Google驱动器设置中未选中“将文档转换为Google文档编辑器格式”选项。这样可以确保您上传的文件与本地文件的格式相同（例如.csv，.txt等）。对我来说，这很有效。

在我的情况下，是因为有多个文件具有相同的名称和扩展名但具有不同的ID，所以我删除了一个文件，并且代码起作用了

从此线程的示例中构建，这里是一个脚本，该脚本遍历gdrive文件夹的所有子文件夹，并下载文件夹结构和其中的所有文件。负责gdrive文档，电子表格和演示文稿。记录文件是否失败：）
