Question

我有一个自定义协议处理程序，该处理程序处理以python2编写的传入消息。数据以使用构造库的编码字节的形式出现，应进行检查并下传给构造解析器。

但是在执行其他任何操作之前，带有“ builtins.TypeError：必须是str而不是字节”的dataReceived函数错误。我尝试将数据存储定义为空字节数组，然后将传入的数据添加到其中，但是没有任何效果。在python终端上独立运行时，代码管道有效，因此我不知道问题出在哪里。

builtins.TypeError: must be str, not bytes

和dataReceived函数：

def dataReceived(self, data):
    log.msg("data received")
    log.msg(data)
    self._remainingData.extend(data)
    while self._remainingData:
        try:
            self._consumeData()
        except IncompleteMessageException:
            # try again later (when we get more data)
            break

修改

它已解决，显然旧的扭曲日志无法像我在python 3中预期的那样工作。log.msg似乎只需要字符串。

dataReceived给出str而不是字节错误，需要字节以便以后解码
