这里大神多，求个python脚本，多谢！

需要尝试下载，记录非404的链接地址亦可。 http://www.example.com/example/1000000000000.png ...... http://www.example.com/example/1299999999999.png

#!/usr/bin/python

import requests

i = 1000000000000
while i < 1300000000000:
    r = requests.get("http://www.example.com/example/"+ str(i) + ".png")
    if (r.status_code != 404):
        f = open("status_code.txt","a")
        f.write(str(i))
        f.write('\n')
    i += 1

因为数量巨大，需要多线程(最好能自定义多少个线程)，麻烦大神弄个python脚本，多谢:)

赶脚可能发到 XXNET 那边人多点，这边基本上没人说话。

简单实现了一个，没有做详细测试，希望可行：

import sys, requests, threading
max_thread_num = 200
num_from = 1000000000000
num_to = 1300000000000

class GET_URL():
    def __init__(self, num_from, num_to, max_thread_num):
        self.lock = threading.Lock()
        self.num_from = num_from
        self.num_to = num_to
        self.thread_num = 0
        self.max_thread_num = max_thread_num

    def worker(self):
        try:
            while self.num_from < self.num_to:
                url = "http://www.example.com/example/"+ str(self.num_from) + ".png"
                self.num_from += 1
                r = requests.get(url)
                self.lock.acquire()
                if (r.status_code != 404):
                    open("status_code.txt", "a").write(str(url) + "\n")
                self.lock.release()
        except:
            pass
        finally:
            self.lock.acquire()
            self.thread_num -= 1
            sys.stdout.write("Threads exist: %d \r" % self.thread_num)
            sys.stdout.flush()
            self.lock.release()

    def start(self):
        new_thread_num = self.max_thread_num - self.thread_num
        if new_thread_num < 1:
            return
        num = self.num_to - self.num_from
        if new_thread_num > num:
            new_thread_num = num
        print ("Running, please wait...")
        for i in range(0, new_thread_num):
            self.lock.acquire()
            self.thread_num += 1
            self.lock.release()
            t = threading.Thread(target = self.worker)
            t.start()

get_url = GET_URL(num_from, num_to, max_thread_num)
get_url.start()

@xyuanmu 想下载个1.2.9版本使用，可是为什么windows版本会被chrome的下载器拦截呢？说会危害计算机安全，1.3.0没问题。

[jzp820927]

chrome 的拦截不是太准确。一般情况可以忽略。

@xyuanmu 多谢！
