今天完成了断点续传部分，即文件传输一半后断掉链接，重新继续发送的实现，以及进度条的实现，今天在测试的时候神兽configpraser模块的害，txt和cfg文件还是不一样啊，最终还是得抓紧看看configpraser模块的模式啊
先展示一下今天的主要两个部分，server端的主要逻辑区域server.py文件

其他部分是完全没有变化的，今天时间有点紧，趁着晚上看看configpraser模块
import configparser config=configparser.ConfigParser() config.read('a.cfg') #查看所有的标题 res=config.sections() #['section1', 'section2'] print(res) #查看标题section1下所有key=value的key options=config.options('section1') print(options) #['k1', 'k2', 'user', 'age', 'is_admin', 'salary'] #查看标题section1下所有key=value的(key,value)格式 item_list=config.items('section1') print(item_list) #[('k1', 'v1'), ('k2', 'v2'), ('user', 'egon'), ('age', '18'), ('is_admin', 'true'), ('salary', '31')] #查看标题section1下user的值=>字符串格式 val=config.get('section1','user') print(val) #egon #查看标题section1下age的值=>整数格式 val1=config.getint('section1','age') print(val1) #18 #查看标题section1下is_admin的值=>布尔值格式 val2=config.getboolean('section1','is_admin') print(val2) #True #查看标题section1下salary的值=>浮点型格式 val3=config.getfloat('section1','salary') print(val3) #31.0
没找到比较清晰的介绍，目前还是一锅粥
明天再看看之前的教学视频吧，然后再补充，今天暂时就这样
