Axios get a file from URL and upload to s3

问题

I'm trying to get files from a site using axios.get, and then uploading it directly to S3. However, the files are corrupted or not encoded properly, and can't be opened after upload. File types range from .jpg, .png to .pdf. Here is my code:

axios.get(URL, {
  responseEncoding: 'binary',
  responseType: 'document',
}).then((response) => {
  return new Promise((resolve, reject) => {
    const s3Bucket = nconf.get('AWS_S3_BUCKET');

    s3.upload({
      'ACL': 'public-read',
      'Body': response.data,
      'Bucket': s3Bucket,
      'Key': `static/${filePath}/${fileManaged.get('filename')}`,
    }, function(err) {
      if (err) {
        return reject(err);
      }
    });
  });
});

I've tried modifying responseType to arraybuffer and creating a buffer using Buffer.from(response.data, 'binary').toString('base64'), to no avail. What am I missing?

回答1:

I was able to get it working by using an arraybuffer and the .putObject function instead of .upload

axios.get(encodeURI(url), {
  responseType: 'arraybuffer',
}).then((response) => {

s3.putObject({
  'ACL': 'public-read',
  'Body': response.data,
  'Bucket': s3Bucket,
  'Key': `static/${filePath}/${fileManaged.get('filename')}`,
} function(err) {

回答2:

Axios encodes the response body in utf8.
You should use other library like request.
