/********************************************************************** * Python UDP broadcast PermissionError: [Errno 13] Permission denied * 說明： *     使用Python3做UDP廣播，遇到這個許可權問題，當時就一陣驚訝，第一看 * 到這種無許可權的問題。 * *                                  2016-12-10 深圳 南山平山村 曾劍鋒 *********************************************************************/一、參考文檔：    Python socket.error: [Errno 13] Permission denied        http://stackoverflow.com/questions/11457676/python-socket-error-errno-13-permission-denied二、錯誤：    1. 錯誤現象：        [[email protected] ~]#  python main.py         fdsaf        Traceback (most recent call last):          File "main.py", line 11, in <module>            s.sendto(‘zengjf‘.encode(‘utf-8‘), address)          PermissionError: [Errno 13] Permission denied        [[email protected] ~]#      2. 錯誤原因：        Set the SO_BROADCAST option, if you actually mean to send to a broadcast address:            s.setsockopt(socket.SOL_SOCKET, socket.SO_BROADCAST, 1)    3. 測試代碼：        import socket        address = (‘255.255.255.255‘, 50000)        s = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)        s.setsockopt(socket.SOL_SOCKET, socket.SO_BROADCAST, 1)        while True:            msg = input()            if not msg:                break            s.sendto(‘zengjf‘.encode(‘utf-8‘), address)        s.close()
