java - p.nettyException - 处理 TooLongFrameException - 玩!框架

Question

我正在尝试开始玩 Play!框架，但是当我尝试使用 activator run 启动服务器时，出现以下错误。我使用的是激活器 1.2.12。

有人熟悉这个错误吗？

我注意到所有激活剂种子都会发生这种情况。运行 activator new 后无需编辑任何文件。我还更新到了最新版本的 activator 和 scala，但没有成功。

Answer 1

请求 header 大小超过 8192 字节。您可以通过在运行应用程序时在系统属性中添加 -Dhttp.netty.maxHeaderSize:xx(xx = 根据您的请求 header 大小所需的大小)来设置它。

或者

尝试减小 header 大小。检查您在请求中发送的 header 。

另请参阅Production Configuration在 application.conf 中配置该值。
