为什么ValueError: malformed node or string当我将以下格式的数据传递到“parse_webhook”函数时会收到此错误消息？
谢谢！
webhook_data = {"side": "BUY","key": "8234023409fa3242309sdfasdf903024917325"}
def parse_webhook(webhook_data):
"""
:param webhook_data: POST data from tradingview, as a string.
:return: Dictionary version of string.
"""
data = ast.literal_eval(webhook_data)
return data
我得到错误：
File "C:\Users\User\anaconda3\lib\ast.py", line 55, in _convert_num
raise ValueError('malformed node or string: ' + repr(node))
ValueError: malformed node or string: {'side': 'BUY', 'key': '8234023409fa3242309sdfasdf903024917325'}
