环境背景 #

• 使用Eikon财富管理版本
• 执行官方示例代码调用ek.get_news_headlines获取LHAG.DE的新闻标题失败
• 此前可用的代理方式已失效

测试代码 #

import eikon as ek

ek.set_app_key("XXX")

# Make API request
df, err = ek.get_news_headlines('R:LHAG.DE', date_from='2019-03-06T09:00:00', date_to='2019-03-06T18:00:00')

if err: print("Error:", err)
else: print("Data:", df)

预期结果 #

返回LHAG.DE的新闻标题，但请求失败。

• 确认API端点适配性
  Eikon财富管理版本的API端点与标准版存在差异，/api/v1/data并非该版本的有效新闻接口端点。需查阅财富管理版专属API文档，确认新闻标题接口的正确调用路径。

• 检查App Key权限
  验证你的App Key已被授权访问新闻类API，且关联的Eikon账户拥有财富管理版的对应数据权限。可通过Refinitiv开发者后台查看App Key的权限配置。

• 更新Eikon Python库
  旧版本库可能未适配财富管理版的API变更，执行命令更新至最新版：

  pip install --upgrade eikon
  

• 调整网络与代理设置
  确认当前网络可正常访问Refinitiv服务器，若需新代理，在代码中添加配置：

  ek.set_proxy(proxy_host="你的代理地址", proxy_port=代理端口)
  

• 校验Instrument格式
  检查R:LHAG.DE是否符合财富管理版的Instrument编码规范，部分版本可能要求不同的前缀或格式。
