我正在尝试使用 Javascript 插件在 Workato 中构建 API 端点。部分要求是根据我定义的模式验证 JSON 请求是否有效。

具体来说，如果未提供必填字段或提供的值与预期的数据类型不匹配（例如，预期数字时的字符串），我需要抛出 400 Bad Request 错误。

我最初的想法是定义一个“checkRequest”函数，该函数将使用每个可能的数据点接收 JSON 请求对象，并基本上通过一个巨大的 if/else if /else 条件列表来测试“null”的每个值并使用“type of" 来测试数据类型，如果遇到错误则返回。

但是，请注意，该架构非常庞大，包含大约 100 个不同的数据点，并且由对象内的嵌套对象组成，因此我希望找到最优化的迭代方式，而不是依赖大量的 if 语句。

请参阅下面的代码和基于架构的请求片段（无法共享完整架构）：

我的代码：

function checkRequest({
  partner_id,
  merchant_reference_id,
  optional_string,
}) {
  let response = {
    validRequest: true,
    responseStatus: "",
    errorTitle: "",
    errorDetail: "",
    errorCode: "",
  };

  let badRequestTitle = "Bad Request";
  let requiredFieldErrorDetail = (field) => {
    return field + " is a required field but was not provided in request.";
  };
  let wrongFormatErrorDetailDetail = (field, inputDataType, expectedDataType) =>
    field +
    " expected data type is " +
    expectedDataType +
    ", but " +
    inputDataType +
    " was received.";

  //partner_id
  if (partner_id == "" || partner_id == null) {
    response.validRequest = false;
    response.errorDetail = requiredFieldErrorDetail("partnerID");
    console.log(response);
    return response;
  } else if (typeof partner_id != "string") {
    response.validRequest = false;
    response.responseStatus = "400";
    response.errorCode = "40001";
    response.errorTitle = badRequestTitle;
    response.errorDetail = wrongFormatErrorDetail(
      "partnerID",
      typeof partner_id,
      "string"
    );
    console.log(response);
    return response;
  }

  //merchant_reference_ID
  else if (merchant_reference_id == "" || merchant_reference_id == null) {
    response.validRequest = false;
    response.errorDetail = requiredFieldErrorDetail("partnerID");
    console.log(response);
    return response;
  } else if (typeof merchant_reference_id != "string") {
    response.validRequest = false;
    response.responseStatus = "400";
    response.errorCode = "40001";
    response.errorTitle = badRequestTitle;
    response.errorDetail = wrongFormatErrorDetail(
      "partnerID",
      typeof merchant_reference_id,
      "string"
    );
    console.log(response);
    return response;
  }
  //else
  else {
    console.log(response);
    return response;
  }
}

let requestBody = {
  partner_id: "",
  merchant_reference_id: "aa",
  optional_string: "3",
};

checkRequest(requestBody);

示例请求片段（假设某些字段是必需的，而其他字段是可选的）：

{
  "application": {
       "partnerReferral": {
            "partnerID": "mg3e09f8-a8dd-44e6-bb06-55293b799318",
            "merchantReferenceID": "mg3e09f8a8dd44e6bb06-55293b799318"
       },
       "businessInformation": {
            "identity": [
                 {
                      "identifier": "EMPLOYER_IDENTIFICATION_NUMBER",
                      "value": "77-1122333"
                 }
            ],
            "businessType": "ASSOCIATION",
            "classification": {
                 "code": "SIC",
                 "value": "string"
            }
    }
  }
}

希望依靠 vanilla Javascript 来实现这一点是最好的方法，但如果需要，可以使用插件。
