无法使用 python 对 SQL 服务器执行 windows 身份验证

Question

我的 Python 下面显示的代码被编写为使用 Windows 身份验证创建 SQL 服务器连接。我有使用 adodbapi 库进行数据库连接的限制。

谁能告诉我这段代码中缺少什么？我参考了图书馆的文档，但没有提到 Windows 身份验证。

我参考了很多关于该异常的文章。但是他们似乎对理解异常的性质及其解决方案没有帮助。

Multiple-step OLE DB operation generated errors. Check each OLE DB status value, if available. No work was done.

代码：

import configparser
import adodbapi
config = configparser.ConfigParser()
config.read("C:/plugin/configsql.ini")
_SERVER_NAME = config['SQL']['SERVER_NAME']
_DATABASE = config['SQL']['DATABASE']
conn = adodbapi.connect("PROVIDER=MSOLEDBSQL;Data Source={0};Database={1};Integrated Security = True;".format(_SERVER_NAME,_DATABASE))
print(conn)

异常：

Traceback (most recent call last):

During handling of the above exception, another exception occurred:

Answer 1

你试过了吗Trusted_Connection=是？这是我的连接字符串，它使用 windows 身份验证（使用 pyodbc），但应该是相同的连接参数，而不是 Integrated Security。

conn = pyodbc.connect('Driver={SQL Server};'
                      'Server=ServerName;'
                      'Database=DatabaseName;'
                      'Trusted_Connection=yes;')

或者 Integrated Security = SSPI，发现这里提到 http://adodbapi.sourceforge.net/quick_reference.pdf

 'Integrated Security=SSPI'
