    这是一个创建于 2525 天前的主题,其中的信息可能已经有所发展或是发生改变。
    逻辑是读取超长文本( 1w 行),循环读一小部分,数据格式为 json,使用 urllib2 提交 json,read()接受返回数据,写入文件,每次运行读取到固定行的时候既不中断也不写入,Ctrl+c 中断后回显为 data=recv ( 1 )这个

    request = urllib2.Request(url)
    while condition :
    time = 重连次数
    for t in range(time):
    try:

    m = res.read()
    伪代码..
