panic: WriteHeader called after Handler finished

[kwzcoder]

部署在云服务器上会panic: WriteHeader called after Handler finished

micro Api panic 必现步骤 :
1. 先把熔断阀值调高
hystrix.DefaultMaxConcurrent = 100000
hystrix.DefaultVolumeThreshold = 100000
2. 熔断超时调低
hystrix.DefaultTimeout = 100
3 .用压测工具 webbench 高并发请求接口必panic "panic: net/http: CloseNotify called after ServeHTTP finished"
在这之前想请教下 Demo里面 user-api里超时设置 hystrix.DefaultTimeout = 5000 , 但是我在breaker/hystrix.go打印依然是默认的1000, 在api/user/main.go设置是不是没有生效? 所以上述的步骤里面几句代码是加在了, breaker/hystrix.go init()函数里面
