不知道如何输入一个函数的输出作为另一个函数的输入

Question

我在这里有一个脚本，其中包含一些基本功能： 函数1-wget打开一个网页并将其保存到本地变量中，然后关闭。 函数2 - 为这个网页抓取md5散列值。 函数3 - 获取散列值并使用常用密码字典对它们进行破解。

我的问题是从函数2获取我的输出并将其插入到函数3中。部分原因是函数2的输出为列表，而函数3正在查找散列值。

你们很有可能通过阅读我的代码来了解更多，下面是我的代码到目前为止。

import sys, hashlib, re, urllib 

def wget(url): # could import webpage_get and use wget() from there instead 
    '''Read the contents of a webpage from a specified URL''' 
    print '[+]---------------------------------------------------------------------------- ' #CHANGE THIS 
    # open URL 
    webpage = urllib.urlopen(url) # opens url like a file 
    # get page contents 
    page_contents = webpage.read() # reads content of webpage 
    return page_contents 
    page_contents = webpage.close() # close webpage 

def findmd5(text): 
    '''Find all md5 hash values''' 
    md5value = re.findall(r'([a-fA-F\d]{32})', text) 
    count = len(md5value) 
    print "[+] Total number of md5 hash values found: %s" % count 
    for x in md5value: 
     print x 


def dict_attack(passwd_hash): 

    dic = ['123','1234','12345','123456','1234567','12345678','password','qwerty','abc','abcd','abc123','111111','monkey','arsenal','letmein','trustno1','dragon','baseball','superman','iloveyou','starwars','montypython','cheese','123123','football','password','batman'] 


    passwd_found = False 
    for value in dic: 
     hashvalue = hashlib.md5(value).hexdigest() 
     if hashvalue == passwd_hash: 
      passwd_found = True 
      recovered_password = value 

    if passwd_found == True: 
     print '[+] Password recovered: %s'% (recovered_password) 
    else: 
     print '[-] Password not recovered' 


def main(): 
    # temp testing url argument 
    sys.argv.append('URL HERE!') 

    # Check args 
    if len(sys.argv) != 2: 
     print '[-] Usage: email_analysis URL/filename' 
     return 
    #call functions 
    try: 
     print '[+] md5 values found: ' 
     print findmd5(wget(sys.argv[1])) 
     print '[+] Cracking hash values: ' 


    except IOError: 
     print 'Error' 

if __name__ == '__main__': 
    main() 

任何帮助，非常感谢！

wget：将return语句设置为最后一条语句。

findmd5：从打印它的结果变为将它们返回到主变量中。

main：在for循环中添加以遍历发现的散列并将dict_attack应用于每个值。

但是我确实没有建立任何中断或停止状态，所以即使找到了，程序也会继续运行。但它仍会打印找到的结果。

import sys, hashlib, re, urllib 

def wget(url): # could import webpage_get and use wget() from there instead 
    '''Read the contents of a webpage from a specified URL''' 
    print ('[+]---------------------------------------------------------------------------- ') #CHANGE THIS 
    # open URL 
    webpage = urllib.urlopen(url) # opens url like a file 
    # get page contents 
    page_contents = webpage.read() # reads content of webpage 
    page_contents = webpage.close() # close webpage 
    return page_contents 

def findmd5(text): 
    '''Find all md5 hash values''' 
    md5value = re.findall(r'([a-fA-F\d]{32})', text) 
    count = len(md5value) 
    print ("[+] Total number of md5 hash values found: %s" % count) 
    return md5value 


def dict_attack(passwd_hash): 

    dic = ['123','1234','12345','123456','1234567','12345678','password','qwerty','abc','abcd','abc123','111111','monkey','arsenal','letmein','trustno1','dragon','baseball','superman','iloveyou','starwars','montypython','cheese','123123','football','password','batman'] 


    passwd_found = False 
    for value in dic: 
     hashvalue = hashlib.md5(value).hexdigest() 
     if hashvalue == passwd_hash: 
      passwd_found = True 
      recovered_password = value 

    if passwd_found == True: 
     print ('[+] Password recovered: %s'% (recovered_password)) 
    else: 
     print ('[-] Password not recovered') 


def main(): 
    # temp testing url argument 
    sys.argv.append('URL HERE!') 

    # Check args 
    if len(sys.argv) != 2: 
     print ('[-] Usage: email_analysis URL/filename') 
     return 
    #call functions 
    try: 
     md5Values = findmd5(wget(sys.argv[1])) 
     for md5value in md5values: 
      dict_attack(md5value) 
      print ('[+] Cracking hash values: ') 


    except IOError: 
     print ('Error') 

if __name__ == '__main__': 
    main()

比利，返回发现的哈希列表，而不是打印它们（它看起来像你认为它是bash，但你不需要“打印”一个函数的输出，就像你在bash，在python中，你可以从字面上返回一个包含元素的数组）。

您的散列表的正则表达式使用\d，但也包括-，它可能会带来不是MD5散列的东西。
