javascript - 安全地将JSON字符串转换为对象(Safely turning a JSON string into an object)

Question

Given a string of JSON data, how can I safely turn that string into a JavaScript object?

(给定一串JSON数据，如何安全地将该字符串转换为JavaScript对象？)

Obviously I can do this unsafely with something like:

(显然，我可以通过以下方式不安全地执行此操作：)

var obj = eval("(" + json + ')');

but that leaves me vulnerable to the JSON string containing other code, which it seems very dangerous to simply eval.

(但这使我容易受到包含其他代码的JSON字符串的影响，仅进行评估似乎很危险。)
