Firebase Cloud Functions v2 Web调用遇CORS错误，Postman正常求解决

我通过Web应用调用Firebase Cloud Functions v2的importScorm函数时遇到了CORS错误，但用Postman调用该函数完全正常。

函数声明如下：

exports.importScorm = functionsV2.https.onRequest({region: 'europe-west3', cpu: 4, memory: "4GiB", timeoutSeconds: 600 }, importScorm);

函数具体代码：

export default async (
  request: functionsV2.https.Request,
  response: functions.Response
) => {

  const { appId, cloudStoragePath, activityId } = request.body;

  console.log(
    JSON.stringify({
      severity: 'info',
      message: '0 - Funzione import SCORM invocata',
      request: request.body,
    })
  );

  // 1. 解压文件
  const timeStart = Date.now();
  const destinationFolder = await unzipFileInGCSFromURL(cloudStoragePath);

  console.log(
    JSON.stringify({
      severity: 'info',
      message: '1 - 文件解压完成',
      timePassed: Date.now() - timeStart
    })
  );

  // 3. 提取文件
  await importActivityFromXMLPath(destinationFolder, appId);

  response.send({
    destinationFolder,
  });
  return;
};

在Firebase Cloud Functions v2中，直接在函数的配置选项里添加cors: true即可解决CORS问题。

修改后的函数声明：

exports.importScorm = functionsV2.https.onRequest({cors:true, region: 'europe-west3', cpu: 4, memory: "4GiB", timeoutSeconds: 600 }, importScorm);
