解析包含换行符的JSON [英] Parsing JSON containing new line characters

问题描述

在我的网站中，我尝试将字符串转换为包含换行符的JSON。

In my website I try to convert a string to JSON which contains a newline.

JSON.parse('{"hallo":"line1\r\nline2","a":[5.5,5.6,5.7]}');

这会产生意外令牌错误。我是否需要以某种方式逃避？

This produces an "Unexpected token" error. Do I need to escape that somehow?

推荐答案

是的，你应该同时逃避 \ n 和 \ r 因为它们属于控制字符列表。可以在此处找到需要转义的完整字符列表。你的代码将是

Yes, you should escape both \n and \r as they belong to the list of control characters. Full list of characters that need to be escaped can be found here. Your code would be

obj = JSON.parse('{"hallo":"line1\\r\\nline2","a":[5.5,5.6,5.7]}');
