我一直在尝试向TCP服务器发送消息，编写了一个简单的脚本来向服务器发送字节数组。问题是我正在发送59个字节，但服务器的接收方超过13K字节。当我调用socket.send（MESSAGE）时会附加一些信息。 我该如何修剪呢？还是可以传递一些参数来绕过呢？
import socket
import time
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.connect(('127.0.0.1', 7046))
s.send('39080080380000000000000400000000000000000007092250121018001'.encode())
print ('connected')
data = s.recv(1024)
s.close()
print ('Received', repr(data))
The dumb data received by the server is as below:
30 38 30 30 38 30 33 38 30 30 30 30 30 30 30 30 0800803800000000

我非常怀疑问题仅在于您的程序。使用netcat作为未修改程序连接到的服务器的快速检查显示：
$ nc -l 7046 | hd
00000000 33 39 30 38 30 30 38 30 33 38 30 30 30 30 30 30 |3908008038000000|
00000010 30 30 30 30 30 30 30 34 30 30 30 30 30 30 30 30 |0000000400000000|
00000020 30 30 30 30 30 30 30 30 30 30 30 37 30 39 32 32 |0000000000070922|
换句话说-它仅收到您希望发送的内容。
从服务器转储很有趣：
30 38 30 30 38 30 33 38 30 30 30 30 30 30 30 30 0800803800000000
它缺少您一开始发送的39。这使我相信服务器会将其解释为您发送的数据的长度，并且根据我在Wireshark: ISO 8583-1中找到的信息，实际上是使用TCP作为传输协议时的情况。
看起来，服务器似乎没有像您假设的那样使用ASCII 39作为长度，而是二进制表示形式0x3339，即13113十进制，与您的“语句很好地匹配...但是服务器是超过13K字节的接收器”。然后，服务器可能会盲目地采用消息的长度而不检查实际长度，这在Heartbleed attack中是非常危险的。就像在Heartbleed中一样，您实际上有一个单位化的缓冲区，从您的问题中可以看出，该缓冲区当前包含一部分ELF二进制文件，但可能还包含一些敏感数据。
无论如何，您的代码可能应该按服务器期望的那样以二进制形式发送消息长度。可能看起来像这样：
import struct
...
msg = b'080080380000000000000400000000000000000007092250121018001'
s.send(struct.pack('>H',len(msg)) + msg)
