某周一的早上,在饭桌上望着闹钟懒洋洋啃着早餐,想着离周五还那么遥远,总有一种崩溃的感觉;任重而道远...习惯开手机,刷微信,不喜欢点赞,不习惯评论,那些晒吃晒喝,晒娃晒照骗的,每天上演,无聊至及;这是无法拒绝的朋友圈...
 
突然看到朋友圈里一条这样的信息:
“一名杀人犯被判死刑。他必须选择三个房间中的一个受死。第一个房间里燃烧着熊熊烈火。第二个房间里全是刺客,手里都拿着上了子弹的枪。而第三个房间则塞满了3年没有进食的狮子。哪一个房间对他来说比较安全呢?”
 
嘿嘿,这第一反应是进哪个房间都必死无疑啊~ 请问你是这么想的吗,我承认我是的~
哈,提示扫描二维码,关注后有答案,好奇害死猫,还是傻愣愣的关注了,运营商就这样圈了我这样一个粉,连看个朋友圈都要成为粉,当今世道不是粉貌似都不能活了~
 
好吧,分析说“死胡同的思维,让我们忘记了 3年没进食的狮子,咋还能起来吃人呢?” 
 
突然不明觉厉~脑袋清醒了很多,尽管面对崩溃的周一,还得去上班啊~

python 多线程扫描开放端口

为什么说python是黑客的语言? 因为很多扫描+破解的任务都可以用python很快的实现,简洁明了。且有大量的库来支持。import socket,sys

from thread_test import MyThread

socket.setdefaulttimeout(1)
#设置每个线程socket的timeou时间,超过1秒没有反应就认为端口不开放
thread_num=4
#线程数目
ip_end=256

scope=ip_end/thread_num

def scan(ip_head,ip_low, port):
try:
# Alert !!! below statement should be inside scan function. Else each it is one s
ip=ip_head+str(ip_low)
print ip
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.connect((ip, port))
#通过这一句判断 是否连通
s.close()
print "ip %s port %d open\n" %(ip,port)
return True
except:
return False


def scan_range(ip_head,ip_range,port):
start,end=ip_range
for i in range(start,end):
scan(ip_head,i,port)

if len(sys.argv)<3:

python 暴力破解wordpress博客后台登陆密码

python爬虫低调的哥哥 发表了文章 • 0 个评论 • 9399 次浏览 • 2016-05-13 17:49 • 来自相关话题

自己曾经折腾过一阵子wordpress的博客,说实话,wordpress在博客系统里面算是功能很强大的了,没有之一。

所以只要使用python+urllib库,就可以循环枚举出用户的密码。而用户名在wordpress博客中就是博客发布人的名字。
 
所以以后用wordpress的博客用户,平时还是把图片验证码的功能开启,怎样安全性会高很多。(其实python也带有一个破解一个验证码的库  - 。-!)# coding=utf-8

python爬虫 模拟登陆知乎 推送知乎文章到kindle电子书 获取自己的关注问题

python爬虫低调的哥哥 发表了文章 • 0 个评论 • 24896 次浏览 • 2016-05-12 17:53 • 来自相关话题

平时逛知乎,上班的时候看到一些好的答案,不过由于答案太长,没来得及看完,所以自己写了个python脚本,把自己想要的答案抓取下来,并且推送到kindle上,下班后用kindle再慢慢看。 平时喜欢的内容也可以整理成电子书抓取下来,等周末闲时看。
 
#2016-08-19更新:
添加了模拟登陆知乎的模块,自动获取自己的关注的问题id,然后把这些问题的所有答案抓取下来推送到kindle

平时逛知乎,上班的时候看到一些好的答案,不过由于答案太长,没来得及看完,所以自己写了个python脚本,把自己想要的答案抓取下来,并且推送到kindle上,下班后用kindle再慢慢看。 平时喜欢的内容也可以整理成电子书抓取下来,等周末闲时看。
 
#2016-08-19更新:
添加了模拟登陆知乎的模块,自动获取自己的关注的问题id,然后把这些问题的所有答案抓取下来推送到kindle

晨跑30分钟 30天

默认分类低调的哥哥 发表了文章 • 0 个评论 • 799 次浏览 • 2016-05-09 21:54 • 来自相关话题

曾经,哦不,是一直到现在,我几乎没有在6点前起过床。然后每天却在叫嚷,时间不够用呀,然后就是熬夜晚睡。虽然知道熬夜等于慢性自杀,可是,和很多人一样,道理都懂,却总是无法彻底执行,每次脑子的两个小人,恶魔总是轻而易举地战胜了天使。 而养成一个习惯,至少要30天。



说实话,我本子记录的计划多的不胜枚举,可是真正被窝执行的却寥寥无几。包括标题的这个,6点起床,晨跑30分钟。 只不过,这一次把笔记本上的记录搬上自己的网站啦。 我不想在众目睽睽之下失信。 我觉得这样会让我执行计划的时候更加坚决。


早起去跑步的好处是:

晨跑能迫使人早起。 是的,正常的话我要睡到8点,早起跑完步还可以多出一个半小时来做其他事情。

晨跑能够提高人整天的代谢水平,从而是全天的能量消耗达到一个较高值,对减肥来说是很有益的。简单来说,晨跑30分钟全天的总代谢就能上升一个台阶,这个比以同样速度夜跑30分钟要有效的多。

晨跑能让人从一夜的睡眠中清醒过来并维持全天的良好身体状态。

晨跑能迅速提升人体的循环,排出一夜睡眠后积累在体内的代谢废物。跑过晨跑后,代谢废物的排出要比不跑快很多。

Firefox抓包分析 (拉勾网抓包分析)

python爬虫低调的哥哥 发表了文章 • 15 个评论 • 11808 次浏览 • 2016-05-09 18:30 • 来自相关话题

针对一些JS网页,动态网页在源码中无法看到它的内容,可以通过抓包分析出其JSON格式的数据。 网页通过通过这些JSON数据对网页的内容进行填充,然后就看到网页里显示相关的内容了。
 
使用过chrome,firefox,wireshark来抓过包,比较方便的是chrome,不需要安装第三方的其它插件,不过打开新页面的时候又要重新开一个捕捉页面,会错过一些实时的数据。 
 
wireshark需要专门掌握它自己的过滤规则,学习成本摆在那里。 
 
最好用的还是firefox+firebug第三方插件。
 
接下来以拉勾网为例。
 
打开firebug功能
 
www.lagou.com 在左侧栏随便点击一个岗位,以android为例 
 





 
在firebug中,需要点击“网络”选项卡,然后选择XHR。
 





 
Post的信息就是我们需要关注的,点击post的链接
 





 
点击了Android之后 我们从浏览器上传了几个参数到拉勾的服务器
一个是 first =true, 一个是kd = android, (关键字) 一个是pn =1 (page number 页码)
 
所以我们就可以模仿这一个步骤来构造一个数据包来模拟用户的点击动作。post_data = {'first':'true','kd':'Android','pn':'1'}
然后使用python中库中最简单的requests库来提交数据。 而这些数据 正是抓包里看到的数据。import requests

url = "http://www.lagou.com/jobs/posi ... ot%3B
return_data=requests.post(url,data=post_data)
print return_data.text

呐,打印出来的数据就是返回来的json数据{"code":0,"success":true,"requestId":null,"resubmitToken":null,"msg":null,"content":{"pageNo":1,"pageSize":15,"positionResult":{"totalCount":5000,"pageSize":15,"locationInfo":{"city":null,"district":null,"businessZone":null},"result":[{"createTime":"2016-05-05

在XHR中点击JSON,就可以看到浏览器返回来的数据了。 是不是跟上面使用python程序抓取的一样呢?
 





 
是不是很简单?
 
如果想获得第2页,第3页的数据呢?
 
只需要修改pn=x 中的值就可以了。post_data = {'first':'true','kd':'Android','pn':'2'} #获取第2页的内容
如果想要获取全部内容,写一个循环语句就可以了。

针对一些JS网页,动态网页在源码中无法看到它的内容,可以通过抓包分析出其JSON格式的数据。 网页通过通过这些JSON数据对网页的内容进行填充,然后就看到网页里显示相关的内容了。
 
使用过chrome,firefox,wireshark来抓过包,比较方便的是chrome,不需要安装第三方的其它插件,不过打开新页面的时候又要重新开一个捕捉页面,会错过一些实时的数据。 
 
wireshark需要专门掌握它自己的过滤规则,学习成本摆在那里。 
 
最好用的还是firefox+firebug第三方插件。
 
接下来以拉勾网为例。
 
打开firebug功能
 
www.lagou.com 在左侧栏随便点击一个岗位,以android为例 
 

Android招聘-招聘求职信息-拉勾网.png

 
在firebug中,需要点击“网络”选项卡,然后选择XHR。
 

post.jpg

 
Post的信息就是我们需要关注的,点击post的链接
 

post_data.jpg

 
点击了Android之后 我们从浏览器上传了几个参数到拉勾的服务器
一个是 first =true, 一个是kd = android, (关键字) 一个是pn =1 (page number 页码)
 
所以我们就可以模仿这一个步骤来构造一个数据包来模拟用户的点击动作。
post_data = {'first':'true','kd':'Android','pn':'1'}

然后使用python中库中最简单的requests库来提交数据。 而这些数据 正是抓包里看到的数据。
import requests

url = "http://www.lagou.com/jobs/posi ... ot%3B
return_data=requests.post(url,data=post_data)
print return_data.text


呐,打印出来的数据就是返回来的json数据

在XHR中点击JSON,就可以看到浏览器返回来的数据了。 是不是跟上面使用python程序抓取的一样呢?
 

dom_data.jpg

 
是不是很简单?
 
如果想获得第2页,第3页的数据呢?
 
只需要修改pn=x 中的值就可以了。
post_data = {'first':'true','kd':'Android','pn':'2'} #获取第2页的内容

如果想要获取全部内容,写一个循环语句就可以了。

wecenter 伪静态规则设置 针对虚拟主机

默认分类低调的哥哥 发表了文章 • 0 个评论 • 856 次浏览 • 2016-05-09 16:42 • 来自相关话题

不得不吐槽一下这个社区的运营的支持,做的比较弱。 缺乏足够技术文档支持,大部分需要用户自己谷歌百度去解决问题。我自己也走了不少的弯路,所以写下来帮助有需要的朋友。

对于虚拟主机(apache的主机),wecenter的伪静态链接的设置,只能通过ftp上传文件来实现。
首先创建一个.htaccess的文件,输入以下内容:<IfModule mod_rewrite.c>
RewriteEngine on
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^(.*)$ index.php/$1 [QSA,PT,L]
</IfModule>
然后上传到网站的根目录下,比如/var/www,然后在wecenter的后台中,进入->管理,进入全局设置->站点功能,然后开启“开启 Rewrite 伪静态” 功能就可以了。

亲测可行。 查看全部

30天,也许会改变你人生的轨迹

30天新尝试低调的哥哥 发表了文章 • 1 个评论 • 1013 次浏览 • 2016-05-09 16:05 • 来自相关话题

30天,在漫长的一生当中,短暂而易逝。就如在不经意间,收到手机的月结扣费短信,然后惊呼 ”这么快又月结扣费。 而在某一集TED演讲中,主人公马特·卡茨却用这30天的时间,尝试新事情,完成了一件又一件看似不可能的事情,因此生活发生了很大的改变,而人生的轨迹也不再是原来那样的两点一线。
 
 






 

看完后,你是否和我一样,有一股冲动,嗯,曾经藏起来的那个儿时的梦想,曾经在脑海中瞬间即逝的疯狂的想法,是否想去尝试一下? 


害怕被人笑? 害怕失败? 没关系,30天之后,又是一条好汉。30天在生命中就如沧海一粟,而你尝试的这些新事情,却会一直印记在脑海中。 

30天,每天坚持写1千字,30天,就可以写3万字,这个篇幅,相当于一部短篇小说了。如果能够坚持3个月,说不定你就可以出版一本书了呢。

以后,当你向别人介绍自己时,你不是说,“我是一名软件工程师",而是“我是某本书的作者”,“我是一名记者","我是一名志愿者", "我是一个TED的演讲者"。 这本身是一件多么酷的一件事情呀。
 
所以这个也是我做这个网站的意义所在,旨在鼓励更多的朋友,行动起来,在接下来的30天里,做一件曾经想做却没机会做的事情。 你每天不仅仅只是上班下班吃饭睡觉这样的流水线般的过着腐朽的日子,一个有肉有灵魂的人物,为什么不能过的出彩? 为什么不去试一试新的事情? 
 
来吧,我已经行动了,我觉得以前错过了很多很多精彩的瞬间,悟以往之不谏,知来者之可追,30天为一个周期,希望能够亡羊补牢吧。
 
互勉~
