我在Scala Play Framework应用程序中遇到了一个问题，该问题使用JDBC向Druid发送SQL查询。当我尝试使用预处理语句执行包含表情符号（例如，ESTA）的Druid SQL查询时，我遇到了HTTP/502错误。具体的错误消息是：🥰
“java.lang.RuntimeException：无法执行HTTP请求，获取HTTP/502。”
版本：

  • play-framework：2.8.16

java：11
Druid：25
Avatica-core：1.17.0*
下面是一个API响应：

我将感谢任何关于如何在Scala Play和JDBC的上下文中处理Druid SQL查询中的表情符号的见解或建议。
我已经验证了同样的查询在没有表情符号的情况下也能正常工作，但是一旦包含了表情符号，就会出现错误。我使用Postman进行测试。值得注意的是，当我直接将包含表情符号的相同查询粘贴到Druid中时，它可以正常工作。这个问题似乎是针对Scala Play，JDBC和Druid之间的交互。

我在经纪人日志中发现的错误是：
500：内容长度不正确390！=374
它仍然发生在later Avatica上吗？
建议将其作为Github Issue放在主存储库中，并提供一个失败的查询示例。注意Druid 28刚刚发布，所以你可能想看看在不同的Druid版本上是否会遇到同样的问题。你可以将28 env设置为https://github.com/implydata/learn-druid并创建一个虚拟查询。
