由于 Httpretty 在 Python 套接字层上工作，因此即使是 Twisted Web 请求也应该被模拟出来。但是我在使用 httpretty 时看到了一些奇怪的行为。它试图以某种方式连接到本地主机。下面的示例显示了差异：

import httpretty
from twisted.internet import reactor
from twisted.internet.defer import Deferred
from twisted.web.client import Agent
from twisted.web.http_headers import Headers
import requests

@httpretty.activate
def main():
    httpretty.register_uri(
        httpretty.GET, "http://example.com",
        body='[{"title": "Test Deal"}]',
        content_type="application/json")

    agent = Agent(reactor)

    d = agent.request(
        'GET',
        'http://example.com',
        Headers({'User-Agent': ['Twisted Web Client Example']}),
        None)

    def cbError(message):
        print 'Async Failed : %s' % message
    d.addErrback(cbError)

    def cbShutdown(ignored): reactor.stop()
    d.addBoth(cbShutdown)

    reactor.run()

    print 'Response received from Sync: %s' % \
            requests.get('http://example.com').status_code

main()

回应是：

Async Failed : [Failure instance: Traceback (failure with no frames): <class 'twisted.internet.error.ConnectionRefusedError'>: Connection was refused by other side: 111: Connection refused.
]
Response received from Sync: 200

我如何将 httpretty 与 Twisted Web 客户端一起使用？

你不能。HTTPretty 正在阻止HTTP 客户端库（如请求）。它不模拟非阻塞套接字。
