使用Python做实现Nginx反向代理

以下代码直接双击，便可实现反向代理，可以解决端口映射和vue安装包编译完不能使用的情况：

#/usr/bin/python
###简易版nginx
import socket
import sys
import os

from _thread import *

HOST = '';PORT = 8881
# print(sys.argv);

print(PORT)
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
print ('Socket created')

try:
    s.bind((HOST, PORT))
    pass
except Exception:
    # print('Bind failed. Error Code : ' + str(msg[0]) + ' Message ' + msg[1])
    # print(str(msg[0]))
    sys.exit()

print ('Socket bind complete')

s.listen(10)

print ('Socket now listening')

def assces_log(request):
    # fp = open('http.log', "aw")
    # fp.write(request+"\r\n")
    # fp.close()
    pass

def parse_request(request):
    request = request.splitlines()
    line = request[0]
    line = line.split();
    dict_request = {'method':line[0], 'path':line[1], 'version':line[2]}
    return dict_request

    print("----s----")
    print(conn)
    print(addr)
    print("------e-------")
    request = conn.recv(1024)
    print (request)
    bb=str(request)
    print(len(bb))
    if len(bb)>10:
        aaa=bb.split("\\r\\n")
