Scrapy是一个用于爬取网站数据的Python框架,而Splash是一个JavaScript渲染服务,可以用于处理动态网页的爬取。在Scrapy中使用Splash可以实现对JavaScript渲染的网页进行爬取。你可以通过在settings.py中添加相应的配置来启用Splash,包括配置Splash服务器地址、设置DupeFilter类、设置HTTP缓存存储等。同时,你还需要在spid.py中导入scrapy_splash包,并在代码中使用SplashRequest()来发送请求获取经过js渲染后的网页内容。

scapy send
Scapy是一个强大的交互式数据包操作程序,它能够伪造或解码多种协议的数据包,发送和捕获数据包,并进行匹配。在Scapy中,有多个函数可以用来发送数据包,其中包括send()和sendp()函数。
send()函数用于发送第三层的IP数据包,而sendp()函数用于发送第二层的Ether数据包。下面是一个使用send()函数发送ICMP数据包的示例代码:
```python
from scapy.all import *
# 构造一个目的地址为"192.168.1.107"的ICMP数据包,并发送
send(IP(dst="192.168.1.107")/ICMP())
```
上述代码中,我们使用IP()函数构造了一个目的地址为"192.168.1.107"的IP数据包,然后将其与ICMP()函数构造的ICMP数据包进行组合,最后使用send()函数发送该数据包。
需要注意的是,使用Scapy发送数据包需要在具有足够权限的环境中运行,例如以管理员身份运行或在root用户下运行。
scapy ipv6
Scapy is a powerful packet manipulation tool that can also be used for IPv6 packet crafting and analysis. Scapy supports IPv6 extension headers and can easily be used to construct and send IPv6 packets.
To create an IPv6 packet with Scapy, you can use the following code snippet:
```
from scapy.all import *
# create an IPv6 packet
ipv6_packet = IPv6(src="2001:db8::1", dst="2001:db8::2")
# send the packet
send(ipv6_packet)
```
In this example, we create an IPv6 packet with a source address of "2001:db8::1" and a destination address of "2001:db8::2". We then use the `send()` function to send the packet.
You can also add IPv6 extension headers to the packet by using the `ExtensionHeader()` function. For example, the following code adds a Hop-by-Hop Options extension header to the IPv6 packet:
```
# create an IPv6 packet with a Hop-by-Hop Options extension header
ipv6_packet = IPv6(src="2001:db8::1", dst="2001:db8::2") / ExtensionHeader(hopopts='\x00\x01\x02\x03')
# send the packet
send(ipv6_packet)
```
In this example, we use the `/` operator to add the Hop-by-Hop Options extension header to the IPv6 packet. We pass the header data as a string of hexadecimal values.
