AttributeError:'NoneType'对象没有属性'connectSSL'

Question

我正在编写一个ssl客户端到我的服务器,它使用python与pyqt4扭曲,我使用QTReactor在PYQT中扭曲但是当我运行代码时出现错误

AttributeError: 'NoneType' object has no attribute 'connectSSL'

我最初的代码是这样的

from OpenSSL import SSL
import sys
from twisted.internet.protocol import ClientFactory
from twisted.protocols.basic import LineReceiver
from twisted.internet import ssl
import qt4reactor

app = QtGui.QApplication(sys.argv)
reactor=qt4reactor.install()
main()
myapp = MainForm()
myapp.show()
reactor.runReturn()
sys.exit(app.exec_())

def main():
    factory = ClientFactory()
    reactor.connectSSL('localhost', 8080, factory, ssl.ClientContextFactory())
    try:
        reactor.run()
    except KeyboardInterrupt:
        reactor.stop()

我运行它时的错误:

Traceback (most recent call last):
  File "client.py", line 51, in <module>
    main()
  File "client.py", line 40, in main
    reactor.connectSSL('localhost', 8080, factory, ssl.ClientContextFactory())
AttributeError: 'NoneType' object has no attribute 'connectSSL'

Answer 1

AttributeError:'NoneType'对象没有属性'connectSSL'

是您尝试调用方法时获得的错误消息None.

这行代码

reactor=qt4reactor.install()

是唯一reactor被分配的地方.错误消息表明reactor正在分配值None.

我可以在该主题上找到的所有网络搜索点击都遵循以下模式:

qt4reactor.install(app)
from twisted.internet import reactor

所以我想这就是你的意思.但我确实承认对这些框架一无所知.
