 原文  2015-10-25 05:01:42  9   2    python/ json/ string/ literals

问题描述

ast.literal_eval is throwing ValueError: malformed string for the following JSON. ast.literal_eval抛出ValueError: malformed string以下JSON的ValueError: malformed string 。 I am unable to spot what the error is. 我无法发现错误所在。 I used online JSON validators, all mention that this a valid JSON. 我使用了在线JSON验证程序，所有人都提到这是有效的JSON。

Can someone help me spot the error with this string? 有人可以帮我找出此字符串的错误吗？

true is an invalid literal in Python: true是Python中的无效文字： 

In [2]: ast.literal_eval('true')
ValueError: malformed node or string: <_ast.Name object at 0x7f32a096d550>

Use json module (specifically json.loads ) when you need to deserialize a JSON document. 需要反序列化JSON文档时，请使用json模块（特别是json.loads ）。

You're using the wrong tool for the job here - ast.literal_eval is intended for parsing python literals from strings into python objects. 您在此处使用了错误的工具ast.literal_eval用于将python文字从字符串解析为python对象。 It is not intended for loading data from serialised JSON into python (although it may also work for that in a subset of cases, because serialised json format happens to overlap with python syntax some of the time). 它不打算将数据从序列化的JSON加载到python中（尽管它在某些情况下也可能适用，因为序列化的json格式有时会与python语法重叠）。

Perhaps you were you looking for json.loads ? 也许您在寻找json.loads ？
