$scope.text = '{"response":"{\"firstName\":\"John\",\"age\":454 }"}';

The problem here is that this isn't JSON.

这里的问题是这不是JSON。

By itself:

通过它自己：

{"response":"{\"firstName\":\"John\",\"age\":454 }"}

… is JSON.

......是JSON。

However, once you wrap it in a JavaScript string literal, the \ is used as an escape character for the JavaScript string literal and gets consumed before it can appear in the JSON.

但是，一旦将其包装在JavaScript字符串文字中，\就会用作JavaScript字符串文字的转义字符，并在它出现在JSON中之前被消耗掉。

When you generate JSON embedded in JS, you need to escape the characters with special meaning in JS:

当您生成嵌入在JS中的JSON时，您需要在JS中转义具有特殊含义的字符：

$scope.text = '{"response":"{\\"firstName\\":\\"John\\",\\"age\\":454 }\"}';

It would also be a good idea to redesign your data structure so that your JSON doesn't contain strings of JSON in the first place:

重新设计数据结构也是一个好主意，这样你的JSON首先不包含JSON字符串：

$scope.text = '{"response": {"firstName":"John","age":454}}';
