python-在FTP服务器上搜索网页

有了FTP服务器的登录口令之后，可以进行测试该服务器是否提供Web服务，其中检测通过nlst()列出的每个文件的文件名是不是默认的Web页面文件名，并把找到的所有默认的网页都添加到retList数组中：

#!/usr/bin/python
#coding=utf-8
import ftplib

def returnDefault(ftp):
    try:
        #nlst()方法获取目录下的文件
        dirList = ftp.nlst()
    except:
        dirList = []
        print '[-] Could not list directory contents.'
        print '[-] Skipping To Next Target.'
        return

    retList = []
    for filename in dirList:
        #lower()方法将文件名都转换为小写的形式
        fn = filename.lower()
        if '.php' in fn or '.asp' in fn or '.htm' in fn:
            print '[+] Found default page: '+filename
            retList.append(filename)
    return retList

host = '10.10.10.130'
username = 'ftpuser'
password = 'ftppassword'
ftp = ftplib.FTP(host)
ftp.login(username,password)
returnDefault(ftp)

            retList.append(fileName)

    if len(retList) == 0:

        print

if __name__ == '__main__':
    main()
