请为什么urllib.request.urlretrieve(）下载文件都是0kb？

Question

我的想法是从url上面利用urllib.request.urlretrieve()远程下载目标音频文件，但是为什么文件都是0kb文件,请问有没有人遇见解决过这个问题能指教一下，谢谢！

#这是我的源码：

import requests
import urllib

url = 'http://i.qingting.fm/wapi/channels/82400/programs/2041562/pagesize/10'

#显示进度
def callbackfunc(blocknum, blocksize, totalsize):
    percent = 100.0 * blocknum * blocksize / totalsize
    if percent > 100:
        percent = 100
    print('下载进度' + '%.2f%%'% percent)

html = requests.get(url)
for n in range(len(html.json()['data']['programs'])):
    m4aUrl_name = html.json()['data']['programs'][n]['name']
    m4aUrl_path = html.json()['data']['programs'][n]['file_path']
    m4aUrl_path = 'http://od.qingting.fm/' + m4aUrl_path
    urllib.request.urlretrieve(m4aUrl_path, m4aUrl_name, callbackfunc)

Answer 1

文件名引起的，你换个别的文件名，最好不要带:的。

Answer 2

我发现是你没有命名文件名的错误，准确说叫文件类型 :

import requests
import urllib

url = 'http://i.qingting.fm/wapi/channels/82400/programs/2041562/pagesize/10'

#显示进度
def callbackfunc(blocknum, blocksize, totalsize):
    percent = 100.0 * blocknum * blocksize / totalsize
    if percent > 100:
        percent = 100
    print('下载进度' + '%.2f%%'% percent)

html = requests.get(url)
for n in range(len(html.json()['data']['programs'])):
    m4aUrl_name = html.json()['data']['programs'][n]['name'].split(':')[1]+'.m4a'
    m4aUrl_path = html.json()['data']['programs'][n]['file_path']
    m4aUrl_path = 'http://od.qingting.fm/' + m4aUrl_path
    
    # 这样下载
    urllib.request.urlretrieve(m4aUrl_path,m4aUrl_name)
    
    # 或者这样，这个可以解决防爬问题
    # print(m4aUrl_name)
    # mp = requests.get(m4aUrl_path)
    # with open(m4aUrl_name,'wb') as f:
    #     f.write(mp.content)
