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，该数据源是Bloomberg订阅产品的一部分。 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），示例程序假设在＆＃39; localhost＆＃39;上有端点。（因为任何装有Bloomberg Professional终端的机器都有。）

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Feed设备包，否则您在本地主机上没有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（和非默认端口号）。

（另请注意，您尝试运行的特定示例程序是＆＃39;发布者＆＃39;，并且需要使用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）< / p>

您的日志文件指示错误9，这似乎表明地址已在使用中。运行netstat命令以查看另一个程序是否已使用您绑定到localhost的端口

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