当console.log返回TRUE值时，解析的JSON中的字段未定义

发布于01月12日

异步存储以字符串形式从存储中返回项目.接下来，将该字符串解析为一个对象.try 从对象获取数据时，返回未定义的错误.

const storage: any = await AsyncStorage.getItem('persist:root');

const state = JSON.parse(storage!);
console.log(state);

const a = JSON.parse(JSON.stringify(state.auth));
console.log(a); <- Normal JSON with fields "user" and "token'
console.log(a.user); <- undefined
console.log(a.token); <- undefined

const refreshToken = a.token.refreshToken; <- undefined

变量state.auth JSON如下所示:

{
  "user":{
},
  "token":{
    "refreshToken":"REFRESH",
    "accessToken":"ACCESS"
  }
}
