使用Python下载并解压缩文件 [英] Download and unzip file with Python
问题描述
我正在尝试下载并打开一个压缩文件,似乎在使用带有zipfile的文件类型句柄时遇到问题。我收到错误AttributeError:addinfourl实例没有属性seek运行时:
I am trying to download and open a zipped file and seem to be having trouble using a file type handle with zipfile. I'm getting the error "AttributeError: addinfourl instance has no attribute 'seek'" when running this:
import zipfile
import urllib2
def download(url,directory,name):
webfile = urllib2.urlopen('http://www.sec.gov'+url)
webfile2 = zipfile.ZipFile(webfile)
content = zipfile.ZipFile.open(webfile2).read()
localfile = open(directory+name, 'w')
localfile.write(content)
localfile.close()
return()
download(link.get("href"),'./fails_data', link.text)
推荐答案
你不能在 urllib2 .urlopen
ed文件。其支持的方法如下: http://docs.python.org/library/urllib.html# urllib.urlopen 。
You can't seek on a urllib2.urlopen
ed file. The methods it supports are listed here: http://docs.python.org/library/urllib.html#urllib.urlopen.
您必须检索该文件(可能使用 urllib.urlretrieve
, http://docs.python.org/library/urllib.html#urllib.urlretrieve ),然后使用 zipfile
。
You'll have to retrieve the file (possibly with urllib.urlretrieve
, http://docs.python.org/library/urllib.html#urllib.urlretrieve), then use zipfile
on it.
或者,您可以 read() / code>
urlopen
ed文件,然后将其放入 StringIO
中,然后使用 zipfile
,如果你想要内存中的压缩数据。另请查看提取
和 extract_all
方法 zipfile
if您只需要提取文件,而不是使用读取
。
Alternatively, you could read()
the urlopen
ed file, then put it into a StringIO
, then use zipfile
on that, if you wanted the zipped data in memory. Also check out the extract
and extract_all
methods of zipfile
if you just want to extract the file, instead of using read
.
