如何生成txt并将其保存到Firebase存储

Question

我正在设置一个新服务器，该服务器支持API请求，这些请求会生成txt文件并将其保存到Firebase存储中。

这是针对herokuapp中的节点js服务器的，我正在使用express，body-parser和firebase admin。当我尝试运行代码时，服务器崩溃。

 async function uploadFile(bucketName, filename) {
  // [START storage_upload_file]
  // Imports the Google Cloud client library
  const {Storage} = require('@google-cloud/storage');

  // Creates a client
  const storage = new Storage();

  var path = `test/${filename}`
  // Uploads a local file to the bucket
  await storage.bucket(bucketName).upload(path, {
    // Support for HTTP requests made with `Accept-Encoding: gzip`
    gzip: true,
    metadata: {
      cacheControl: 'no-cache', //the contents will change
    },
  });

  console.log(`${filename} uploaded to ${bucketName}.`);
  // [END storage_upload_file]
}




app.get('/test', async (req, res) => {
var path = req.body.path
var filename = req.body.filename
var content = req.body.content
var filepath = `${filename}.txt`
  fs.writeFile(filepath, content, function(err) {
    if(err) {
        return console.log(err);
    } 
    console.log("The file was saved!");
    uploadFile(MY-BUCKET, filepath)
  });

});

最后，api应该生成简单的txt文件，并在每次出现新请求时编辑其内容。
