可以将响应设置为ArrayBuffer客户端，但不能使用Node.js

Question

I have a client side form using XMLHTTPResponse that allows me to get response data saved as a file. It sets the response type as arraybuffer as follows before the rest of the blob conversion occurs:

xhr.responseType = "arraybuffer";

I have been searching and finding multiple methods to create an arraybuffer, but none that detail how to take the response in node to an arraybuffer. I am using unirest as follows:

unirest.post('http://myvendorsapi/Upload_PDF')
  .headers({ 'Content-Type': 'multipart/form-data' })
  .field('filename', filename)// Form field
  .attach('file', fileloc)// Attachment
  .end(function (response) {
     console.log(response);
     var returnfile = response.body;
     // Need logic to convert to arraybuffer
  });

How do I set the response type to an arraybuffer or convert my response to an arraybuffer?

If you want to get more raw response data, I would ditch the unirest library and use something thinner such as request . Unirest claims to 'parse responses' for you, which sounds like something that you don't want. If you simply want to save the raw response body to a file, using request, you could do something like this:

var formData = {
    filename: filename,
    file: fs.createReadStream(fileloc)
}
var req = request.post({url: 'http://myvendorsapi/Upload_PDF', formData: formData})
req.pipe(fs.createWriteStream('OUTPUT FILE NAME'))
