Pyhttpx

基于socket开发的一个网络库,供研究https/tls参考 如果你用过requests,它将会变得非常容易

版本协议支持

• tls1.2/tls1.3
• h1/h2

PyPI:

$ python -m pip install --upgrade pip
$ python -m pip install pyhttpx

安装依赖

requirement.txt

cryptography==36.0.1
rsa==4.8
pyOpenSSL==21.0.0

brotli==1.0.9
hpack==4.0.0

GET

>>> import pyhttpx
>>> sess = pyhttpx.HttpSession()
>>> r = sess.get('https://httpbin.org/get',headers={'User-Agent':'3301'},cookies={'k':'3301')
>>> r.status_code
200
>>> r.encoding
'utf-8'
>>> r.text
'{\n  "args": {}, ...
>>> r.json
{'args': {},...

如果你想知道原生http报文是否达到预期,你可以这样

>>> r.request.raw
b'GET /get HTTP/1.1\r\nHost: httpbin.org ...

POST

>>> r = sess.post('https://httpbin.org/get',data={})

HTTP PROXY

>>> proxies = {'https': 'http://username:password@host:port'}
>>> r = sess.post('https://httpbin.org/get',proxies=proxies)

ALLOW_REDIRECTS

>>> r = sess.post('https://httpbin.org/get',allow_redirects=True)

支持ssl上下文

如果数据是空字符,表示收到fin,服务器断开连接

>>>from pyhttpx.layers.tls.pyssl import SSLContext,PROTOCOL_TLSv1_2
>>>import socket
>>>addres = ('httpbin.org', 443)
>>>context = SSLContext(PROTOCOL_TLSv1_2, http2=False)
>>>sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM, 0)
>>>ssock = context.wrap_socket(sock, server_hostname=addres[0])
>>>ssock.connect(addres)
>>>m = 'GET / HTTP/1.1\r\nHost: %s\r\n\r\n' % addres[0]
>>>ssock.sendall(m.encode())
>>>r = ssock.recv()
b'HTTP/1.0 200 OK\r\n'...
