我需要用 puppeteer 下载图像。这里的问题是，buffer通过goto方法返回。我认为它会返回图像加载的序列。所以 writeFile 方法只获取最后一个缓冲区。是否有其他承诺方法来处理序列缓冲区？

const puppeteer = require('puppeteer-core');
const fs = require('fs').promises;

(async () => {
  const options = {
   product: 'chrome',
   headless: true,
   pipe: true,
   executablePath: 'chrome.exe'
  };

  const browser = await puppeteer.launch(options);
  const page = await browser.newPage();
  const response = await page.goto('https://static.wikia.nocookie.net/naruto/images/d/dd/Naruto_Uzumaki%21%21.png/revision/latest?cb=20161013233552');
  
  // save buffer to file
  await fs.writeFile('file.jpg', await response.buffer());
  browser.close();
})();

上传成功并返回 id。并尝试将其驱动。它存在。但驱动器中不存在文件？这是什么？我尝试按 id 上传到特定文件夹。文件上传位置在哪里？

const { google } = require('googleapis');
const fs = require('fs');
const credentials = require('./credentials.json');
const scopes = [
    'https://www.googleapis.com/auth/drive'
];

const auth = new google.auth.JWT(
    credentials.client_email, null,
    credentials.private_key, scopes
);

const drive = google.drive({ version: 'v3', auth });

(async () => {
    
    const fileMetadata = {
        name: 'naruto.jpg'
    };

    const media = {
        mimeType: 'image/jpeg',
        body: fs.createReadStream('naruto.jpg')
    };

    const res = await drive.files.create({
        q: `'1PhND1fjEDnL63BbrLmw2V4M4B6jIfP8Q' in parents`,
        resource: fileMetadata,
        media: media,
        fields: 'id'
    });

    console.log(res.data);
    
})();
