所以我想用urllib2制作进度条或百分比。正在下载进度条urllib2 python
,我发现这个代码在不同的问题上堆栈溢出:
import urllib2, sys
def chunk_report(bytes_so_far, chunk_size, total_size):
percent = float(bytes_so_far)/total_size
percent = round(percent*100, 2)
sys.stdout.write("Downloaded %d of %d bytes (%0.2f%%)\r" %
(bytes_so_far, total_size, percent))
if bytes_so_far >= total_size:
sys.stdout.write('\n')
def chunk_read(response, chunk_size=8192, report_hook=None):
total_size = response.info().getheader('Content-Length').strip()
total_size = int(total_size)
bytes_so_far = 0
while 1:
chunk = response.read(chunk_size)
bytes_so_far += len(chunk)
if not chunk:
break
if report_hook:
report_hook(bytes_so_far, chunk_size, total_size)
return bytes_so_far
if __name__ == '__main__':
response = urllib2.urlopen('http://www.ebay.com');
chunk_read(response, report_hook=chunk_report)
,但我不知道它在哪里下载它。
因此,如何修复此代码以知道它下载到的位置或编码进度条。
