我完全迷路了，不知道如何修复这个错误，因为我不明白错误的含义，也无法在Zeep中在线找到关于这个特定错误的任何信息

有什么想法吗？

我不知道

zeep

，但这个错误意味着python试图调用为字符串对象上的字典保留的方法，即

>>x='a string'-->x.keys（）-->AttributeError:'str'对象没有属性'keys'

。这只适用于dict，即>>>

x={'a key'：'a value'}->x.keys（）-->dict_key（['a key']）

。我猜python会将您的

json

请求数据

视为

str

。好的，这是一个开始。据我所知，Zeep对象应该返回一个字典，但可能我没有正确地使用它。我会调查的，谢谢你的提示！它可能返回了JSON。您解决了这个问题吗？@user1558604我确实解决了它，使用Zeep的原始响应选项，然后用beautiful soup解析结果。
