Javascript：解析document.cookie JSON对象的问题

On the server I'm storing a JSON object as a cookie (using Django / json.dumps), it looks like so:

在服务器上我将一个JSON对象存储为cookie（使用Django / json.dumps），它看起来像这样：

'{"name": "Simon", "gender": "M"}'

On the client when I run document.cookie I can see the cookie and it looks like so:

在我运行document.cookie的客户端上，我可以看到cookie，它看起来像这样：

"user="{\"name\": \"Simon\"\054 \"gender\": \"M\"}";

I have a small function which retrieves a cookie by name ( getCookie('user') )it returns a string:

我有一个小函数，它按名称检索cookie（getCookie（'user'））它返回一个字符串：

"{\"name\": \"Simon\"\054 \"gender\": \"M\"}"

I want to parse this back to a JSON object for further use on the client however JSON.parse() returns the error: "SyntaxError: Unexpected number".

我想将其解析回JSON对象以便在客户端上进一步使用，但是JSON.parse（）返回错误：“SyntaxError：Unexpected number”。

Whats strange is if you run the following:

如果你运行以下内容，那有多奇怪：

JSON.parse("{\"name\": \"Simon\"\054 \"gender\": \"M\"}")

directly in the console it works fine. Any ideas?

直接在控制台中它工作正常。有任何想法吗？

If there is a better way to store the cookie etc im open to ideas

如果有更好的方式存储cookie等我对想法开放

Thanks in advance.

提前致谢。

The \054 is breaking your json. it's a encoded , (comma).

\ 054打破了你的json。它是一个编码的，（逗号）。

This:

这个：

string.replace(/\\054/g, ',');

should probably do it.

应该这样做。

Comma is an illegal character in Cookie... and is not the only one, for prevent problem maybe you can encode your JSON befoure put in cookie:

逗号是Cookie中的非法字符...并且不是唯一的一个，为了防止问题，也许你可以编码你的JSON befoure放入cookie：

encodeURIComponent('{"name": "Simon", "gender": "M"}');
//return "%7B%22name%22%3A%20%22Simon%22%2C%20%22gender%22%3A%20%22M%22%7D"

decodeURIComponent('%7B%22name%22%3A%20%22Simon%22%2C%20%22gender%22%3A%20%22M%22%7D');
//return '{"name": "Simon", "gender": "M"}'

This answer explains better the world of "allowed character" in cookie: Allowed characters in cookies

这个答案更好地解释了cookie中“允许字符”的世界：cookie中允许的字符
