【问题描述】：

import os
os.system("touch shellback.py")
a = raw_input("IP of The Listener(you)> ")
print "Set ip to "+ a +""
file = open("shellbackdoor.py", "a")
file.write("from socket import *\n")
file.write("HOST = '"+ a +"'\n");
file.close()
file = open("shellback.py", "a")
file.write("PORT = 443\n")
print "You might to to port forward your router to the port 443"
file.write("s = socket(AF_INET, SOCK_STREAM)\n")
file.write("s.setsockopt(SOL_SOCKET, SO_REUSEADDR, 1)\n")
file.write("s.bind((HOST, PORT))\n")
file.write("print 'Listening on "+ a +":%s' % str(PORT)\n")
file.write("s.listen(10)\n")
file.write("conn, addr = s.accept()\n")
file.write("print 'Connected by', addr\n")
file.write("data = conn.recv(1024)\n")
file.write("while 1:\n")
file.write("     command = raw_input("> ")")
file.write("     conn.send(command)\n")
file.write("     if command == "quit":\n")
file.write("          break\n")
file.write("     data = conn.recv(1024)\n")
file.write("     print data\n")
file.write("conn.close()\n")

我一直在遇到语法错误

file.write("     if command == "quit":\n")

不知道为什么

上面用了两行

file.write("     command = raw_input("Insert your command or quit>")")

但在我将其更改为之后它停止了错误

file.write("     command = raw_input("> ")")

【问题讨论】：

标签： python python-2.7 shell syntax-error

【解决方案1】：

你做得对。但是您需要像我在下面显示的那样转义双引号

代码中的一行：

file.write("     if command == "quit":\n")

固定线路

file.write("     if command == \"quit\":\n")

希望对你有帮助
