爬虫下载图片时的一个问题

Question

downloadlist=bsobj.findAll(src=True)

downloadlist就是要下载的图片的集合。

然后fileURL就是图片的URL了，

for download in downloadlist:
    fileURL=getabsoluteurl(baseURL,download["src"])
    print(fileURL)
    if fileURL is not None:
        urlretrieve(fileURL,getdownloadpath(fileURL,downloadDirectory),cbk)

下面就是报错原因：

//ossweb-img.qq.com/images/lol/v3/logo.png
Traceback (most recent call last):
  File "C:/Users/18022863809/Desktop/python_work/文件下载.py", line 44, in <module>
    urlretrieve(fileURL,getdownloadpath(a,downloadDirectory),cbk)
  File "C:/Users/18022863809/Desktop/python_work/文件下载.py", line 29, in getdownloadpath
    os.makedirs(directory)

    mkdir(name, mode)
FileNotFoundError: [WinError 53] 找不到网络路径。: '//ossweb-img.qq.com/images/'

上面就是报错原因，非常奇怪，我直接在浏览器复制这个URL能够访问，为什么这里找不到网络路径呢

Answer 1

url地址不是绝对的路径，你把获取到的相对路径转换成绝对路径就可以了
