执行上述代码段时，会引发以下错误：
ValueError: Expecting property name: line 1 column 2(char 1)
我哪里出错？
答案 0 :(得分：0)
正如您在json parsing tool中看到的那样，该文件不是有效的json文件。
错误消息是关于文件的第二个字符：u中的u'Messages'。
但'Messages'也无效。
是"Messages"。
'Body': '{" ... '之前{是什么
答案 1 :(得分：0)
此文件不是有效的 JSON文件，因此json.load无法加载它。
JSON文件中的所有键必须为字符串
在您的情况下，某些键的前缀字母为 u ，您需要将其删除。
