golang"s echo framework log is located in the file. By default, stdio, is found to be unavailable after modification
I don"t know what the problem is, file design 0777
fd, _ := os.OpenFile(
LogPath,
os.O_RDWR|os.O_APPEND,
0666,
)
e.Use(middleware.LoggerWithConfig(
middleware.LoggerConfig{
Format: "method=${method}, uri=${uri}, status=${status}\n",
Output: fd,
}))
e.Logger.SetOutput(fd)
problem has been resolved, not a code problem. It"s a log file deadlock.
