連接到Oracle的Python記錄

我正在使用Kenneth Ritz的記錄庫連接到Oracle。連接到Oracle的Python記錄

db = records.Database('oracle://scott/[email protected]:1521/orcl')

但它總是拋出此錯誤

DatabaseError: (cx_Oracle.DatabaseError) 
ORA-12545: Connect failed because target host 
or object does not exist.

但是通過SQL Plus中連接工作得很好

sqlplus scott/[email protected]/orcl:1521 

SQL*Plus: Release 12.1.0.1.0 Production on Sat Mar 11 17:29:19 2017

有趣的觀察

db = cx_Oracle.connect('scott/[email protected]:1521/orcl') **<--Works** 

db.version 
'12.1.0.1.0' 

db = records.Database('oracle+cx_oracle://scott/[email protected]:1521/orcl') 
doesn't work

任何想法，我在做什麼錯這裏？

records依賴sqlalchemy做數據庫繁重工作。請參閱SQLAlchemy的documentation：

因此，URI應該是這樣的： oracle+cx_oracle://user:[email protected]:1521/dbname

感謝UKU的pointer.Tried該DB = records.Database（「ORACLE + cx_oracle：//斯科特/老虎@localhost：1521/orcl'）但仍然沒有歡樂 – user3249433

scott/tiger'部分的含義是什麼？ –

對不起，我的這個作品scott是用戶名和密碼是tiger.db = records.Database（'oracle + cx_oracle：// scott：tiger @ localhost：1 521/orcl'） – user3249433
