with open("test.log", 'r', encoding='utf-8') as f:
    while True:
        rsize = 1024*1024*1                                 #每次读取1M大小
        lines = f.readlines(rsize)
        if not lines:
           break
        for line in lines:
            message = line.replace("\n", "")               
            print(message)
