检查无限多个自生成的URL的有效性，如果有效，则安全响应（http 200）

Question

我想检查一个无限数量的自我生成的网址的有效性，如果有效的安全主体的响应在一个文件。URL看起来是这样的：https://mydomain.com/+随机字符串（例如https://mydomain.com/ake3t），我想用字母表“abcdefghijklmnopqrstuvwxyz0123456789”生成它们，然后用暴力尝试所有可能的方法。在

我用python编写了一个脚本，但由于我是一个绝对的初学者，它非常慢！因为我需要的东西非常快，所以我试着用了，因为我认为它是专门为这种工作。在

现在的问题是我不知道如何动态地生成url，我不能预先生成它们，因为它不是固定数量的url。在

有人能告诉我如何做到这一点，或者向我推荐另一种更适合这项工作的工具或库吗？在

更新： 这是我用的脚本，但我觉得它很慢。最让我担心的是，如果我使用多个线程（在threadsNr中指定），它会变慢

import threading, os
import urllib.request, urllib.parse, urllib.error 

threadsNr   = 1                                    
dumpFolder    = '/tmp/urls/'               
charSet     = 'abcdefghijklmnopqrstuvwxyz0123456789_-' 
Url_pre    = 'http://vorratsraum.com/'
Url_post    = 'alwaysTheSameTail'

# class that generate the words
class wordGenerator ():

    def __init__(self, word, charSet):
        self.currentWord = word
        self.charSet = charSet

    # generate the next word set that word as currentWord and return the word
    def nextWord (self):
        self.currentWord = self._incWord(self.currentWord)
        return self.currentWord

    # generate the next word
    def _incWord(self, word):
        word = str(word)                        # convert to string

        if word == '':                          # if word is empty 
            return self.charSet[0]              # return first char from the char set
        wordLastChar = word[len(word)-1]        # get the last char
        wordLeftSide = word[0:len(word)-1]      # get word without the last char
        lastCharPos  = self.charSet.find(wordLastChar)  # get position of last char in the char set

        if (lastCharPos+1) < len(self.charSet):         # if position of last char is not at the end of the char set
            wordLastChar = self.charSet[lastCharPos+1]  # get next char from the char set

        else:                                           # it is the last char

你想要暴力还是随机？下面是一个具有重复字符的顺序暴力方法。速度将在很大程度上取决于您的服务器响应。还要注意，这很可能会很快产生拒绝服务条件。在

import itertools
import url

pageChars = 5
alphabet = "abcdefghijklmnopqrstuvwxyz0123456789_-"

#iterate over the product of alphabet with <pageChar> elements
#this assumes repeating characters are allowed
# Beware this generates len(alphabet)**pageChars possible strings
for chars in itertools.product(alphabet,repeat=pageChars):
    pageString = ''.join(chars)

    urlString = 'https://mydomain.com/' + pageString

    try:
        url = urllib2.urlopen(url)

    except urllib2.HTTPError:
        print('No page at: %s' % urlString)
        continue     

    pageDate = url.read()
    #do something with page data
