我的要求是从某个网站http://clientdownload.xyz.com/Documents/abc.zip下载 abc.zip 文件
对于这个活动,我编写了一个 python 脚本,如下所示:
url_to_check = 'http://clientdownload.xyz.com/Documents/abc.zip'
username = "user"
password = "pwd"
p = urllib2.HTTPPasswordMgrWithDefaultRealm()
p.add_password(None, url_to_check, username, password)
handler = urllib2.HTTPBasicAuthHandler(p)
opener = urllib2.build_opener(handler)
urllib2.install_opener(opener)
zip_file = urllib2.urlopen(url_to_check).read()
file_name = 'somefile.zip'
meta = zip_file.info()
file_size = int(meta.getheaders("Content-Length")[0])
print "Downloading: %s Bytes: %s" % (file_name, file_size)
with open(file_name, 'wb') as dwn_file:
dwn_file.write(zip_file.read())
而我在运行脚本时收到以下错误:
文件“updateCheck.py”,第 68 行,在 check_update zip_file = urllib2.urlopen(url_to_check).read() 文件“/usr/lib/python2.7/urllib2.py”,第 126 行,在 urlopen 返回 _opener.open( url,数据,超时)文件“/usr/lib/python2.7/urllib2.py”,第 406 行,打开响应 = meth(req,响应)文件“/usr/lib/python2.7/urllib2.py” , 第 519 行, 在 http_response 'http', 请求, 响应, 代码, msg, hdrs) 文件 "/usr/lib/python2.7/urllib2.py", 第 444 行, 错误返回 self._call_chain(*args) 文件“/usr/lib/python2.7/urllib2.py”,第 378 行,在 _call_chain 结果 = func(*args) 文件“/usr/lib/python2.7/urllib2.py”,第 527 行,在 http_error_default 中引发 HTTPError (req.get_full_url(), 代码, msg, hdrs, fp) urllib2.HTTPError: HTTP 错误 401:未经授权
我已经正确输入了用户名和密码,但它会引发未经授权的错误。
当我尝试使用带有-http-user and --ask-password
选项的 wget 链接下载它时,我能够下载该文件。
也使用相同的脚本,我能够正确地从其他服务器下载文件。
我运行此脚本以获取更多信息:
import urllib2, re, time, sys
theurl='http://clientdownload.xxx.com/Documents/Forms/AllItems.aspx'
req = urllib2.Request(theurl)
try:
handle = urllib2.urlopen(req)
except IOError, e:
if hasattr(e, 'code'):
if e.code != 401:
print 'We got another error'
print e.code
else:
print e.headers
print e.headers['www-authenticate']
