Firebase云函数调用Lemonsqueezy API时的参数与内部错误问题

我通过curl传递参数调用Firebase Cloud Functions的testActivateLicense函数时，反复触发内部服务器错误。排查过程中：

• 先修复了logAndSendError函数未传入response参数导致的TypeError；
• 再将request.query改为request.body，解决了参数无法正确获取的问题。

但当前仍存在两个问题：调用Lemonsqueezy的License验证接口时，明明已正确获取参数，API却提示license_key和instance_name为必填项；同时logAndSendError函数依然存在未传入response的问题。以下是相关代码及日志：

原curl命令及报错 #

curl -X POST "https://testactivatelicense-a123bcdefg-uc.a.run.app/" -d license_key=3F9D04E3-F661-4F33-BB22-53FE83F111DC -d instance_name=test_1234 
Internal Server Error%

初始函数代码 #

exports.testActivateLicense = onRequest(async (request, response) => {
  try {
    const licenseKey = request.query.license_key;
    const instanceName = request.query.instance_name;
    logger.log("Received request with licenseKey:", licenseKey, "and instanceName:", instanceName);

    const params = new URLSearchParams({license_key: licenseKey, instance_name: instanceName}).toString();
    logger.log("Constructed query parameters:", params);

    response.status(response.status).send(response.data);
  } catch (error) {
    logAndSendError(error);
  }
});

function logAndSendError(error, res) {
  logger.error("Error occurred:", error.message);

  if (error.response) {
    logger.error("Error response status:", error.response.status);
    logger.error("Error response data:", JSON.stringify(error.response.data, null, 2));
    res.status(error.response.status).send(error.response.data);
  } else {
    res.status(500).send(error.message);
  }
}

function logAndSendError(error, res) {
  logger.error("Error occurred:", error.message);

  if (error.response) {
    logger.error("Error response status:", error.response.status);
    logger.error("Error response data:", JSON.stringify(error.response.data, null, 2));
    res.status(error.response.status).send(error.response.data);
  } else {
    res.status(500).send(error.message);
  }
}

GCP初始错误日志 #

TypeError: Cannot read properties of undefined (reading 'status')

参数获取问题修复记录 #

日志显示参数为undefined，将request.query改为request.body后，参数可正常获取。

当前函数代码 #

exports.testActivateLicense = onRequest(async (request, response) => {
  try {
    const licenseKey = request.body.license_key;
    const instanceName = request.body.instance_name;
    logger.log("Received request with licenseKey:", licenseKey, "and instanceName:", instanceName);

    const params = new URLSearchParams({license_key: licenseKey, instance_name: instanceName}).toString();
    logger.log("Constructed query parameters:", params);

    logger.log("Making request to Lemonsqueezy API with URL:", validateUrl);
    const res = await axios.post(activateUrl, params, {
      headers: {
        "Authorization": `Bearer ${testApiKey}`,
        "Accept": "application/json",
        "Content-Type": "application/vnd.api+json",
      },
    });

    logger.log("Received response from Lemonsqueezy API with status:", res.status);
    logger.log("Response data:", JSON.stringify(res.data, null, 2));
    response.status(res.status).send(res.data);
  } catch (error) {
    logAndSendError(error);
  }
});
