Question

嗨，我正在尝试处理https://firebase.google.com/docs/database/rest/retrieve-data中给出的Firebase Rest服务的响应，以下是我收到的示例响应：

import numpy as np
import matplotlib.pyplot as plt

theta = list(range(1,366))
theta = [i* 2 * np.pi / 365  for i in theta]
radii=np.random.rand(365)

ax = plt.subplot(111, projection='polar')
ax.set_theta_zero_location('N')
ax.set_xticklabels(['Jan', 'Feb', 'Mar', 'Apr', 'Mai', 'Jun', 'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec'])

因此，响应是一个随机键和员工界面：

{
  "2": {
    "name": "John",
    "surname": "Cena"
  },
  "12": {
    "name": "Murphy",
    "surname": "R ichard"
  },
  .
  .
  .
  "8": {
    "name": "Alisha",
    "surname": "Johnson"
  }
}

响应中的元素数量将有所不同。我想在打字稿中处理这个问题。我将其作为对象接收，甚至没有映射数组。 interface Employee{ private name:string; private surname:string; }。请提供解决方法。

我要说的全部是基于您将要处理的数据

// you can assign the response to employees
const employees: any = res;

// or you can convert this to array;
const data = Object.keys(res).map((key) => {
  return { ...res[key], id: key }; <-- here this can be pass to a constructor to return a Employee Object, also you can add a key/id field to the entity.
});

// or many more methods, its all based on how you are going access the data.
