示例xml内容：

<peach>

</DataModel>

</peach>

如上这段内容，其实是peach数据模型的一段定义，今天通过脚本模拟自动建模，生成的文档含有大量的mutable="false"的内容。根据peach的描述，这一属性的意义可以让peach忽略对其进行mute操作(实际好像还是会mute)，为了简洁起见，减少建模过程中的费脑，直接将数据模型定义文件中重复出现的muta […]

通过python可以免去编译很快速的实现ssl socket的模拟，如下server和client的示例，作为日常学习ssl的行为模式，应该是能满足了： sslServer:

import socket

import ssl

import sys

def sslServer(host, port):

# create user defined SSLContext

ssl_context = ssl.SSLContext()

ssl_context.verify_mode = ssl.CERT_REQUIRED

ssl_context.load_verify_locations(cafile='RootCA.pem')

ssl_context.check_hostname = False

# test this protocol with client's PROTOCOL_TLSv1_2

ssl_context.protocol = ssl.PROTOCOL_TLS_SERVER

ssl_context.load_cert_chain("Server.pem", "Server.key")

cipher_suites = 'ECDHE-RSA-AES256-GCM-SHA384:AES256-GCM-SHA384:DHE-RSA-AES256-GCM-SHA384:ECDHE-RSA-AES256-GCM-SHA384'

ssl_context.set_ciphers(cipher_suites)

try:

server = socket.socket(socket.AF_INET, socket.SOCK_STREAM, 0)

# set reuse options

server.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1)

server.bind((host, port))

server.listen(1)

with ssl_context.wrap_socket(server, server_side=True) as ssl_server:

conn, addr = ssl_server.accept()

print("accept conn from %s" % str(addr))

# get the ssl cipher info

print('ssl cipher: {}'.format(conn.cipher()))

while conn:

recv_data = conn.recv(1024)

print("recv: %s" % repr(recv_data))

if not recv_data:

break

conn.sendall(recv_data)

except Exception as e:

print(e)

if __name__ == '__main__':

print('ssl ver: {}'.format(ssl.OPENSSL_VERSION))

try:

sslServer(sys.argv[1], int(sys.argv[2]))

except KeyboardInterrupt:

print('server exit')

sslClient:

import socket

import ssl

import sys

def sslClient(host, port):

# create defauly_context

ssl_context = ssl.create_default_context(cafile='RootCA.pem')

ssl_context.load_cert_chain("Client.pem", "Client.key")

ssl_context.protocol = ssl.PROTOCOL_TLSv1_2

# crl test

# ssl_context.verify_flags = ssl.VERIFY_CRL_CHECK_LEAF

# ssl_context.load_verify_locations("Server.crl")

cipher_suites = 'DHE-RSA-AES256-GCM-SHA384:ECDHE-RSA-AES256-GCM-SHA384'

ssl_context.set_ciphers(cipher_suites)

client = socket.socket(socket.AF_INET, socket.SOCK_STREAM)

with ssl_context.wrap_socket(client, server_hostname='Server') as ssl_client:

ssl_client.connect((host, port))

# get the ssl cipher info

print('ssl cipher: {}'.format(ssl_client.cipher()))

while True:

send_data = input("send:")

ssl_client.sendall(send_data.encode())

recv_data = ssl_client.recv(1024)

print("recv:%s" % recv_data)

if __name__ == '__main__':

print('ssl ver: {}'.format(ssl.OPENSSL_VERSION))

try:

sslClient(sys.argv[1], int(sys.argv[2]))

except KeyboardInterrupt:

print('client exit')
