使用yup进行确认

const schema = yup.array()
    .of(
      yup.object().shape({
        name: yup.string().required("Required"),
        school: yup.mixed().oneOf(['school 1','school 2']),
        address: yup.mixed().oneOf(['newyork','washington'])
      }).noUnknown(true)
    )

并验证，

await schema.validate(your_object).catch(function (err) {
  err.name; // => 'ValidationError'
  err.errors;
});

• 注：未测试此验证 *

下面是您尝试执行的操作的简化函数

const validateJSON = (json) => {
  if (!Array.isArray(json)) {
    return false;
  }
  for (const element of json) {
    if (Object.keys(element).length !== 3) {
      return false;
    }
    if (element.school !== "school 1" && element.school !== "school 2") {
      return false;
    }
    if (element.address !== "newyork" && element.address !== "washington") {
      return false;
    }
  }

  return true;
};

那就用const isValid = validateJSON(json);
