Ruby on Rails JSON.parse unexpected token error
提问by SZH
I am trying to parse JSON data in my Rails 3 application with JSON.parse. I keep getting this error:
我试图在我的 Rails 3 应用程序中解析 JSON 数据JSON.parse。我不断收到此错误：
737: unexpected token at '{\"0\":{\"class\":\"window\",\"text\":\"Testing\",\"style\":\"position: absolute; top: 8px; left: 8px; width: 560px; height: 290px; z-index: 0; \"}
737：'{\"0\":{\"class\":\"window\",\"text\":\"Testing\",\"style\":\"position: absolute; 处的意外标记；顶部：8px；左侧：8px；宽度：560px；高度：290px；z-index：0；\"}
The actual JSON is a lot longer, but it is basically the same.
实际的JSON要长很多，但基本上是一样的。

Well, we can only answer based on the part of the JSON you showed us, but it has two problems:
好吧，我们只能根据您展示给我们的 JSON 部分来回答，但是它有两个问题：
- All the quote characters (
") are escaped; they don't need to be unless they are used in a double-qoted string, which it appears they are not. - You are missing a closing brace (
}).
- 所有引号字符 (
") 都被转义；它们不需要，除非它们被用在双引号字符串中，看起来它们不是。 - 您缺少右大括号 (
})。
Otherwise it passes based on https://jsonlint.com/.
否则它会基于https://jsonlint.com/传递。

In my case it was a hidden tab character which showed up only when i pasted it into vim.
就我而言，它是一个隐藏的制表符，仅在我将其粘贴到 vim 中时才会显示。

You can directly use JSON.Parse()in-build method:
您可以直接使用JSON.Parse()in-build 方法：
content = "[{\"addon_id\":\"1\",\"addon_price\":\"5\"}]"
# OUTPUT at Console => "[{\"addon_id\":\"1\",\"addon_price\":\"5\"}]"
JSON.parse(content.gsub('\"', '"'))
# OUTPUT at Console => [{"addon_id"=>"1", "addon_price"=>"5"}]
