Typescript 按键获取字符串数组

对于Angular 7应用程序，我有以下几点：

var name_key = "name";
var language_key = "language";
var type_key = "type"

然后，API返回以下JSON：

{
  "errors": {
    "language": [
      "language not found"
    ],
    "name": [
      "name not found",
      "name must not exceed 200 characters"
    ]
  }
}

我需要获取每个密钥的错误消息，以便：

"name" > "name not found",
         "name must not exceed 200 characters"

"language" > "language not found"

"type" > NULL

---

如何执行此操作？

看起来您需要一种类似数组的语法，该语法允许您使用变量键访问对象字段：

const apiResponse = getApiData(); //your API response
const errorKeys = [name_key, language_key, type_key];
let errors = [];
for (let errKey of errorKeys) {
  errors.push(apiResponse.errors[errKey]);
}

注意：在typescript中通常不使用var关键字，因为它会弄乱作用域。使用或替代
