verify your json string. If it is ok try this:
验证您的 json 字符串。如果没问题，试试这个：
var jsonStr="your json string";
var json=JSON.stringify(jsonStr);
json=JSON.parse(json)
回答by Amgad
When you're typing a string in javascript, the \ is treated as escaping character, while you need it in your json to actually be a \ and not escaping character.
当您在 javascript 中输入字符串时，\ 被视为转义字符，而您在 json 中需要它实际上是一个 \ 而不是转义字符。
You need to change the \"to \\"and \nto \\n, while keeping the \'because it is already an escaping character and it should be parsed okay
您需要更改\"to\\"和\nto \\n，同时保留 the\'因为它已经是一个转义字符，应该可以正常解析
