带空格的JSON数据

我有以下JSON数据结构。我想知道如何提取提供密钥的数据。

"Meta Data": {
    "1. Information": "High School",
    "2. Name": "St Marys"
},
"Teachers' Names": {
    "Grade I": {
        "1. English": "Amanda Fernandez",
        "2. Sociology": "Christina Andrew",
        "3. Applied Science": "George Binu"
    },
    "Grade II": {
        "1. English": "Gedfd Hkdfd",
        "2. Sociology": "lksdg klsdfd",
        "3. Applied Science": "some one else"
    }
  }
}

我使用nodejs并在请求模块下的'body'对象中获取此数据。如何提取上面的一年级，英语教师姓名？我尝试了身体[“教师姓名] [0]，看看它是否会给我至少一级的I级对象。但事实并非如此。有人可以帮助我吗？

有多种方法可以实现相同的目标（一如既往）。但要在这里回答你的问题，我们采用一种方法来实现你的目标。

const body = {
  "Meta Data": {
    "1. Information": "High School",
    "2. Name": "St Marys"
  },
  "Teachers' Names": {
    "Grade I": {
      "1. English": "Amanda Fernandez",
      "2. Sociology": "Christina Andrew",
      "3. Applied Science": "George Binu"
    },
    "Grade II": {
      "1. English": "Gedfd Hkdfd",
      "2. Sociology": "lksdg klsdfd",
      "3. Applied Science": "some one else"
    }
  }
}

// to access known keys you could do it like this
console.log(data['Teachers\' Names']['Grade I']['1. English']) // this will output "Amanda Fernandez"
