简单的 PycURL 例子
import pycurl
import StringIO
url = "http://www.google.com/"
crl = pycurl . Curl ( )
crl. setopt ( pycurl . VERBOSE ,1 )
crl. setopt ( pycurl . FOLLOWLOCATION , 1 )
crl. setopt ( pycurl . MAXREDIRS , 5 )
crl. fp = StringIO . StringIO ( )
crl. setopt ( pycurl . URL , url )
crl. setopt ( crl. WRITEFUNCTION , crl. fp . write )
crl. perform ( )
print crl. fp . getvalue ( )
PycURL 自动处理cookie
import pycurl
import StringIO
url = "http://www.google.com/"
crl = pycurl . Curl ( )
crl. setopt ( pycurl . VERBOSE ,1 )
crl. setopt ( pycurl . FOLLOWLOCATION , 1 )
crl. setopt ( pycurl . MAXREDIRS , 5 )
crl. fp = StringIO . StringIO ( )
crl. setopt ( pycurl . URL , url )
crl. setopt ( crl. WRITEFUNCTION , crl. fp . write )
# Option -b/--cookie <name=string/file> Cookie string or file to read cookies from
# Note: must be a string, not a file object.
crl. setopt ( pycurl . COOKIEFILE , "cookie_file_name" )
# Option -c/--cookie-jar <file> Write cookies to this file after operation
# Note: must be a string, not a file object.
crl. setopt ( pycurl . COOKIEJAR , "cookie_file_name" )
crl. perform ( )
print crl. fp . getvalue ( )
