Urllib2 是否包含有读取长度,求出错原因

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

try except 没有起作用...程序没有中断..

查询到结果原因为连接被远端重置...设置 urlopen(timeout)是否有用..另外链接被重置 程序为何没有响应...

@bazingaterry
request = urllib2.Request(url)
while condition :
time = 重连次数
for t in range(time):
try:
time.sleep(0.5)
res = urllib2.urlopen(request,json)
except urllib2.URLError, e:
if t < (time-1):
record_log()
m = res.read()
伪代码..

表示没看懂你说的啥意思,代码也不全
