如何通过python twisted HTTPClient生成POST和GET请求？

Posted 2021-03-27

我正在写一个HTTP客户端。这是一个简单的模拟银行网站。它需要能够发送两种请求：

1. 用户登录时：POST / login？user = bob＆pass = abc123 HTTP / 1.1主机：bank.com
2. 当用户转账时：GET / transfer？to = badguy＆amt = 100 HTTP / 1.1主机：bank.com Cookie：login = fde874

我正在通过python twisted实现它，我写了一个HTTPClient的子类：

class BankClient(HTTPClient):
    def genReq():
       # How to write code to generate and send the Two request?

    def connectionMode(self):
        genReq()



class BankCllientFactory(ClientFactory):
    protocol = BankClient
    def __init__(self):
       self.done = Defered()


def main(reactor):
   factory= BankClientFactory()
   reactor.connectTCP('localhost',8080,factory)
   return factory.done
if __name__ =='__main__':
    task.react(main)

答案

你想停止使用HTTPClient。相反，使用Agent或第三方treq。

用GET生成POST和Agent：

from twisted.web.client import Agent
from twisted.internet import reactor
agent = Agent(reactor)
d_get = agent.request(b"GET", uri)
d_post = agent.request(b"POST", uri)

用GET生成POST和treq：

import treq
d_get = treq.get(url)
d_post = treq.post(url)
