从 object/array 获取价值

Question

我只需要在 JS 的变量中获取令牌。

    {
  "user": {
    "id": "string",
    "nickName": "string",
    "score": 0,
    "rank": 0
  },
  "token": "string"
}

这是我保存在变量中的响应，但我只需要从令牌中获取“字符串”值

Answer 1

如果您已将此响应存储在变量中，例如：

let response = {
  "user": {
    "id": "string",
    "nickName": "string",
    "score": 0,
    "rank": 0
  },
  "token": "string"
}

您可以像这样从“令牌”中提取值属性

let tokenFromObject = response.token

或

let tokenFromObject = response["token"]

或

let { token } = response

Answer 2

你应该能够获取你得到这个 json 的变量并执行此操作：

let a = {"user":{},"token": "string"}; // this is what you got

console.log(a["token"])  // a["token"] will give you "string"

Get value from object/array
