c++ - Bloomberg Api 连接问题 - Connection failed

Question

我正在试用 bloomberg c++ api 示例。收到以下错误:

有人知道这个 api 吗？它试图连接的连接是什么？我是否需要任何额外的服务器监听端口 8194？

Answer 1

为了使用 Bloomberg API SDK，您需要一个 Bloomberg 数据源，它作为 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(就像任何运行 Bloomberg Professional 终端的机器上一样) .

您在 Linux 机器上运行它，除非您在该机器上安装了数据馈送设备包，否则您在“本地主机”上没有 API 端点。如果您的网络中有一个 API 端点，您需要为示例程序指定正确的命令行参数，以告诉它您的 API 端点的 IP 地址(和端口号，如果非默认)。

(另请注意，您尝试运行的特定示例程序是一个“发布者”，需要一个平台 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)
