【问题描述】：

我的代码是：

import xmpp

jabberid = "admin@mydomain.com"
password = "password"
receiver = "admin@mydomain.com"
message  = "hello world"

jid = xmpp.protocol.JID(jabberid)
connection = xmpp.Client(server=jid.getDomain())
connection.connect()
connection.auth(user=jid.getNode(), password=password,resource=jid.getResource())

我收到此错误：

我正在使用 xmpppy 模块，但我不知道为什么？因为我传递给 connection.auth 的参数都是字符串

【问题讨论】：

不要认为异常与您传入的参数有关。听起来像 xmpp 库中的错误。您能否首先确保所有要求都是最新的？

标签： python authentication connection xmpp xmpppy

【解决方案1】：

您必须解码 lib 中“auth”文件中的数据。这条线一定是这样的。

data=base64.b64decode(incoming_data).decode()
