根据提示信息，代码运行后返回的是 {'data': None, 'code': 403, 'msg': '会话失效!'}，即会话失效。因此，无法通过 ['data']['cid'] 获取到值，导致出现 TypeError: 'NoneType' object is not subscriptable 错误。

解决方法是重新生成一个新的会话，或者检查之前生成的会话是否过期。可以尝试通过修改 payload 中的参数来重新生成会话，例如增加一个随机数参数，绕过之前的会话。另外，也可以尝试联系接口提供方，寻求帮助。

这段代码是用来生成AI对话回答的，其中包括以下参数：
- prompt: 代表AI的输入，即对话的开端
- history: 代表之前的对话历史，可以为空
- streaming: 是否使用流式对话，即实时回答对话

如果使用流式对话，该函数会在对话过程中不断生成回答；如果不使用流式对话，该函数会在输入完整的对话后一次性生成回答。该函数返回的是一个生成器，每次调用生成一个回答，其中包含了对话历史和AI的回答结果。

你可以使用QPushButton的setStyleSheet方法设置按钮的样式表，将文本旋转90度，例如：

self.submit_btn.setStyleSheet('color: #fff; background-color: #20639b; border: none; font-size: 24px; padding: 10px; border-radius: 5px; transform: rotate(90deg);')

这里使用了transform属性将文本旋转了90度。
