I was trying to GET a binary data using request, and had something like:
var requestSettings = {
method: 'GET',
url: url,
};
request(requestSettings, function(error, response, body) {
// Use body as a binary Buffer
}
But body was always a few bytes different from expected. After further investigation I found out that request assumed body is string and replaced all non-unicode bytes.
I tried to add
encoding: 'binary'
to requestSettings but it didn't help.
How can I get the binary data?
OK, after a lot of digging, I found out that requestSettings should have:
encoding: null
And then body will be of type Buffer, instead of the default, which is string.
