属性错误：加载（scapy数据包.py)

Question

我到处找了找，找不到任何关于这件事的事。这个问题可能是由于我对Python有点陌生，我希望能在这里得到一些帮助。在

我在2009年看到了这篇博文：http://stacksmash.org/2009/09/packet-visualization-with-python/

但是，当我运行这个程序时，在Scapy的1129行中得到以下错误数据包.py在

$ python test-image.py 
Traceback (most recent call last):
  File "test-image.py", line 9, in <module>
    if(len(pkt.load) > imgWidth):
  File "/usr/local/lib/python2.7/dist-packages/scapy/packet.py", line 
    192, in __getattr__
  fld,v = self.getfield_and_val(attr)
  File "/usr/local/lib/python2.7/dist-packages/scapy/packet.py", line 
  189, in getfield_and_val
  return self.payload.getfield_and_val(attr)
  File "/usr/local/lib/python2.7/dist-packages/scapy/packet.py", line 
  189, in getfield_and_val
  return self.payload.getfield_and_val(attr)
  File "/usr/local/lib/python2.7/dist-packages/scapy/packet.py", line 
  1125, in getfield_and_val
  raise AttributeError(attr)
AttributeError: load

这可能是新的库版本的问题（考虑到这是一篇2009年的博客文章），还是我在这里遗漏了什么？在

这对我来说适用于Python 3.6.4：

from PIL import Image
from scapy.all import rdpcap

capture = rdpcap('./capture.pcap')
imgHeight = len(capture)

imgWidth = max(len(packet) for packet in capture)

imgSize = imgWidth, imgHeight
print('Image Size: ', imgSize)

img = Image.new('RGB', imgSize, (255, 255, 255))

for i in range(0, imgHeight):
    for j in range(0, len(capture[i])):
        color = ord(str(capture[i])[j])
        # print('Writing pixel', (j,i), 'with value:', color)
        img.im.putpixel((j,i), (0, color, 0))

img.save('./result.png')
