Bloomberg Api连接问题 - <localhost:8194>连接失败

Question

我正在尝试使用bloomberg c ++ api示例.得到以下错误:

有没有人对api有所了解？它尝试连接的连接是什么？我是否需要在端口8194上侦听任何其他服务器？

Answer 1

要使用Bloomberg API SDK,您需要Bloomberg数据源,该数据源作为Bloomberg订阅产品的一部分提供.API SDK使用端口8194上的TCP连接连接到数据馈送端点(如您所见),示例程序假设"localhost"上有一个端点(因为任何具有运行Bloomberg Professional终端的计算机上都有) .

您在Linux计算机上运行此操作,除非您在该计算机上安装了数据源设备包,否则"localhost"上没有API端点.如果网络中有API端点,则需要为示例程序指定正确的命令行参数,以告知其API端点的IP地址(以及端口号,如果非默认值).

(另请注意,您尝试运行的特定示例程序是"发布者",并且需要Platform API端点进行连接,它不能与任何其他类型的API端点一起使用)
