我正在尝试在我的机器上运行Bloomberg示例代码。我已经创建了teamviewer VPN来安装Bloomberg终端的机器。我也禁用了两台机器的防火墙。
Bloomberg Terminal已启动并登录。
代码：

# options = blpapi.SessionOptions()
# options.setServerHost('7.220.156.135')
# options.setServerPort(8194)
# session = blpapi.Session(options)
#
# session.start()
# ContributionsMktdataExample.py

听起来您正在尝试使用Desktop APIv3从运行终端的计算机上获取数据到您的计算机。这不受支持。如果您使用Desktop API，则只能连接到localhost。您可以连接到另一台计算机以获取Bloomberg数据的唯一情况是使用Sever API或B-PIPE时。
即使支持此功能，桌面API合约也规定您无法将Bloomberg数据发送到其他计算机。
