网络爬虫的分类

网络爬虫应该选择 Nutch、Crawler4j、WebMagic、scrapy、WebCollector 还是选择其他?
 
网络爬虫我们可以分为三大类型:
 (1)分布式爬虫:Nutch
 
(2)JAVA爬虫:Crawler4j、WebMagic、WebCollector
 
(3)非JAVA爬虫:scrapy(基于Python语言开发)
 
网络爬虫采集数据过程中,经常会遇到被反爬虫机制限制,最常见的就是ip被限制,网站根据ip的访问频率来识别
 
判断爬虫,当相同的ip频繁的对目标服务器进行访问,那么就会触发服务器的反爬虫机制,这个时候ip就会被限制
 
或者无法进行访问,爬虫工作将无法继续进行,因此需要借用到万变ip代理来突破ip的限制。

疫情以来,所有企业都上班延期选择在线复工,在我们居家自我隔离期间,极验观察爬虫却没有消停,反而爬虫行为更加活跃且更胜往常。本周五,我们和无糖信息一起聊聊线上爬虫的“疫情”。

修改win7 hosts文件IP域名映射问题的一个坑

因为讨厌一些网站的弹窗,还有想要高效地学习,把一些娱乐网站给屏蔽了,比如QQ。
所以在hosts文件中添加了如下内容:
路径:C:\Windows\System32\drivers\etc
 127.0.0.1 qq.com
127.0.0.1 cnbeta.com
10.4.16.75 windows10.microdone.cn
50.112.79.106 mukodik
0.0.0.0 account.jetbrains.com
结果发现一直无法生效。
后来在ping下发现,ping qq.com 返回的是127.0.0.1是生效的。
但是ping www.qq.com是能够ping到腾讯的服务器的,原来问题在于,你在浏览器输入qq.com,浏览器默认帮你加了www.前缀。
 
所以你要hosts文件生效,就需要把www.的前缀也加上去。
然后重新刷新下DNS就可以了
ipconfig /flushdns
还有就是,如果你用了代理软件,比如lantern之类的,这个hosts文件也不会起作用。 查看全部

阻挡黑客的最原始最暴力的方法 ---用胶带粘住你的摄像头

网络安全李魔佛 发表了文章 • 0 个评论 • 4277 次浏览 • 2016-06-23 22:15 • 来自相关话题

Facebook 的 CEO 扎克伯格经常喜欢发发照片跟网友互动什么的。最近他在 Facebook 个人账号上面发了一条消息,照片中的他扛着一个镜框庆祝 Instagram 的月活用户数突破了 5 亿大关。但是眼尖的用户却注意到了其他的细节—似乎扎克的笔记本摄像头和麦克风插口都是用胶带蒙住的(题图红色箭头所指)。

扎克为什么要把摄像头蒙住呢?这得先说一下 Ratting(Remote Access Trojan)这种行为。所谓的 Ratting,是指黑客通过植入木马远程控制受害用户设备的行为,而进行这种行为的黑客一般叫做 ratter。除了窃取设备的敏感数据以外,激活用户摄像头和麦克风偷拍视频也是 ratter 常干的事情。

不过扎克伯格这么专业的人也把摄像头蒙起来究竟是偏执狂还是好做法呢?安全专家认为是后者,原因有三:

一是扎克伯格是一个高价值的攻击目标。无论是情报机构还是为了罪犯无疑都会对扎克伯格的资料虎视眈眈,而对于那些为了证明自己黑客功力的人来说,扎克也是一个很理想的目标。所以采取预防措施是很自然的事情。

二是把采集音视频的入口盖住是一种成本低廉且基本的安全防护办法。如果想窃听安全会议,有经验的黑客一般都会先数数哪些设备没有遮住摄像头然后再确定下手的目标。

三是扎克未必就不会被攻破。事实上本月初就爆出了黑客袭击扎克伯格部分社交网络,盗取了他的 Twitter、Pinterest、LinkedIn 帐号的消息。把这两件事联系在一起,更容易解释他的那台 Macbook 上面的胶带。

事实上,采取这种做法的人并不止扎克一个。就连 FBI 局长 James Comey 也把自己的笔记本摄像头蒙上了胶带—原因很简单,因为他看到一个比他更聪明的人也这么干。所以你要不要也蒙上呢? 查看全部

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 • 16 个评论 • 19895 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?

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。

疫情以来,所有企业都上班延期选择在线复工,在我们居家自我隔离期间,极验观察爬虫却没有消停,反而爬虫行为更加活跃且更胜往常。本周五,我们和无糖信息一起聊聊线上爬虫的“疫情”。

修改win7 hosts文件IP域名映射问题的一个坑

因为讨厌一些网站的弹窗,还有想要高效地学习,把一些娱乐网站给屏蔽了,比如QQ。
所以在hosts文件中添加了如下内容:
路径:C:\Windows\System32\drivers\etc
 127.0.0.1 qq.com
127.0.0.1 cnbeta.com
10.4.16.75 windows10.microdone.cn
50.112.79.106 mukodik
0.0.0.0 account.jetbrains.com
结果发现一直无法生效。
后来在ping下发现,ping qq.com 返回的是127.0.0.1是生效的。
但是ping www.qq.com是能够ping到腾讯的服务器的,原来问题在于,你在浏览器输入qq.com,浏览器默认帮你加了www.前缀。
 
所以你要hosts文件生效,就需要把www.的前缀也加上去。
然后重新刷新下DNS就可以了
ipconfig /flushdns
还有就是,如果你用了代理软件,比如lantern之类的,这个hosts文件也不会起作用。 查看全部

阻挡黑客的最原始最暴力的方法 ---用胶带粘住你的摄像头

Facebook 的 CEO 扎克伯格经常喜欢发发照片跟网友互动什么的。最近他在 Facebook 个人账号上面发了一条消息,照片中的他扛着一个镜框庆祝 Instagram 的月活用户数突破了 5 亿大关。但是眼尖的用户却注意到了其他的细节—似乎扎克的笔记本摄像头和麦克风插口都是用胶带蒙住的(题图红色箭头所指)。

扎克为什么要把摄像头蒙住呢?这得先说一下 Ratting(Remote Access Trojan)这种行为。所谓的 Ratting,是指黑客通过植入木马远程控制受害用户设备的行为,而进行这种行为的黑客一般叫做 ratter。除了窃取设备的敏感数据以外,激活用户摄像头和麦克风偷拍视频也是 ratter 常干的事情。

不过扎克伯格这么专业的人也把摄像头蒙起来究竟是偏执狂还是好做法呢?安全专家认为是后者,原因有三:

一是扎克伯格是一个高价值的攻击目标。无论是情报机构还是为了罪犯无疑都会对扎克伯格的资料虎视眈眈,而对于那些为了证明自己黑客功力的人来说,扎克也是一个很理想的目标。所以采取预防措施是很自然的事情。

二是把采集音视频的入口盖住是一种成本低廉且基本的安全防护办法。如果想窃听安全会议,有经验的黑客一般都会先数数哪些设备没有遮住摄像头然后再确定下手的目标。

三是扎克未必就不会被攻破。事实上本月初就爆出了黑客袭击扎克伯格部分社交网络,盗取了他的 Twitter、Pinterest、LinkedIn 帐号的消息。把这两件事联系在一起,更容易解释他的那台 Macbook 上面的胶带。

事实上,采取这种做法的人并不止扎克一个。就连 FBI 局长 James Comey 也把自己的笔记本摄像头蒙上了胶带—原因很简单,因为他看到一个比他更聪明的人也这么干。所以你要不要也蒙上呢? 查看全部
