この質問は次のようになります：http：//stackoverflow.com/questions/12471180/frequently-http-500-internal-error-with-google-drive-api-drive-files-get500内部の答えはありませんがサーバーエラー。
Googleドライブ（Python）を使用して、すべてのファイルを反復処理し、各ファイルのアクセス許可を変更しています。次のような応答があります：エラーが発生しました：https：//www.googleapis.com/drive/v2/files/12345CuV3wBsvZDM3ZmRjNWQtMWZkNC00NzQzLTg2MzMtM2IyY2Q0YWU1OTll/permissions？alt=jsonが「内部エラー」を返しました
私のコードはグーグルの例からかなりクッキーカッターであり、次のとおりです：

「パーミッションの挿入」ではなく「パーミッションの追加」というクラウディオのアドバイスに従って、コードを次のように変更します。
import gdata.docs
import gdata.docs.service
userNameAtGmailCom = 'PersonAEmailAddress@gmail.com'
password = 'PersonAPassword'
personToShareWith = "PersonB@gmail.com"
def login(userNameAtGmailCom, password, personToShareWith):
client = gdata.docs.service.DocsService()
client.ClientLogin(userNameAtGmailCom, password)
documents_feed = client.GetDocumentListFeed()
for document_entry in documents_feed.entry:
print document_entry.title.text
scope = gdata.docs.Scope(value=personToShareWith, type='user')
role = gdata.docs.Role(value='reader')
acl_entry = gdata.docs.DocumentListAclEntry(scope=scope, role=role)
created_acl_entry = client.Post(acl_entry, document_entry.GetAclLink().href, converter=gdata.docs.DocumentListAclEntryFromString)
login(userNameAtGmailCom, password, personToShareWith)
これにより、PersonAがファイルを共有したことを通知する電子メールがPersonBに送信されます。これは、PersonBのアプリがPersonAのファイルを読み取れるようにするPersonBからアプリを実行できる場合を意味しますか？
