1 接口响应内容过大（约4M）导致请求卡住不动

查看 gateway 日志如下：

gateway               | 2023-02-22 12:27:11,015  WARN        reactor.netty.channel.FluxReceive: 299 - [8fe9d3b0-4, L:/172.30.10.3:39621 ! R:172.30.10.15/172.30.10.15:8004] An exception has been observed post termination, use DEBUG level to see the full stack: io.netty.handler.codec.http.websocketx.CorruptedWebSocketFrameException: Max frame length of 10485760 has been exceeded.

2 解决

1. 在 gateway 的 docker-compose-gateway.yaml 中 添加 environment

   SPRING_CLOUD_GATEWAY_HTTPCLIENT_WEBSOCKET_MAX-FRAME-PAYLOAD-LENGTH: 512000000

2. 执行 msctl reload gateway 重启 gateway 。
