我来加几个参数: ` curl -q -Lm 9
ip.cn/ `
-q, --disable
If used as the first parameter on the command line, the curlrc config file will not be read and used.
-L, --location
(HTTP) If the server reports that the requested page has moved to a different location (indicated with a Location: header and a 3XX response code), this option will make curl redo the request on the new place.
-m, --max-time <seconds>
Maximum time in seconds that you allow the whole operation to take.
