如何使用请求库在Node.js中执行此curl操作

Question

How can I convert this curl operation using request Node.js library:

curl -L -X GET -H "Content-Type:application/json" -H "Authorization: authorization..." -H "Scope: 11111111" https://url/download >> file.gz

    /*the -L is curl option which means --location      Follow redirects (H)
         --location-trusted  Like '--location', and send auth to other hosts (H)*/

Answer 1

If you just want to download to a file, you can use a head request type.

The request will look like so:

request.head({
    url: "https://url/download",
    followAllRedirects: true,
    headers: {
    'Content-Type': 'application/json',
    'Authorization':'authorization...',
    'Scope': '11111111'
  }
}, (err, res, body) => {
  request('https://url/download')
    .pipe(fs.createWriteStream(`tmp/${res.path}`)).on('close', (data, err) => {
            if(err) console.log(`Unable to write to file ${err}`)
            console.log('Done')
    })
})

I have used a similar snippet which worked well

Use Postmans code generator

1. Click code on the top left
2. Paste your curl request
3. Select Node.js Request from dropdown on top left of popup
4. You should then get JS snippet converted from your working cURL request

Here is the solution we have to put request inside another because: so the first request returns the url and the second one will download the file

const options = {
  url: url,
  headers: {
    Authorization: `auth`,
    'scope': profileId,
    'content-type': 'application/json'
  },
};
const r = request.get(options, async (err, res, body) => {
    const fileStream = fs.createWriteStream(`${path}.gz`);
    request(res.request.uri.href).pipe(fileStream);
    // path exists unless there was an error
  });
