@d18 嗯，我准备直接用 socket 了

@zhangpeter 已经贴出来代码了

pm = urllib3.PoolManager()
r = pm.request('GET', url_path, preload_content=False)
data_received = 0
start_time = time.time()
now = time.time()
last_time = time.time()
with open(output_file_name, 'w') as out_file:
while True:
data = r.read(120000)
if not data:
break

代码是这样的，我打算改成非阻塞的？会不会有用？

很急的求助啊，自顶
