python 下载文件汇总

简单文件下载 使用htttplib2:

h = httplib2.Http()
url = ''
resp, content = h.request(url)

if resp['status'] == '200':
    with open(filename, 'wb') as f:
        f.write(content)

urllib: 简单文件下载

filename = urllib.unquote(url).decode('utf8').split('/')[-1]
urllib.urlretrieve(url, filename)

较大文件下载

def down_file():
    url = ""

    file_name = url.split('/')[-1]
    u = urllib2.urlopen(url)
    f = open(file_name, 'wb')
    meta = u.info()
    file_size = int(meta.getheaders("Content-Length")[0])

    file_size_dl = 0
    block_sz = 8192
    while True:
        buffer = u.read(block_sz)
        if not buffer:
            break

        file_size_dl += len(buffer)
        f.write(buffer)
    f.close()
