I was trying to use Node.js supertest to test some REST API I had written. I need to send a request equivalent to the following CURL request:
curl -X POST -F api_key=KEY -F image=@my_file http://localhost:3000/v1/upload
I tried the following, but I got Uncaught TypeError: first argument must be a string or Buffer
.
request.post('/v1/upload')
.type('form')
.field('api_key', 'abcd')
.attach('image', 'some path')
.end(function(err, res) {
res.body.error.should.equal('Invalid username/api_key.');
done();
});
I also tried sending it as this:
request.post('/v1/upload')
.type('form')
.field('api_key', 'abcd')
.attach('image', 'some path')
.end(function(err, res) {
res.body.error.should.equal('Invalid username/api_key.');
done();
});
but the server can only parse the file upload request and not the api_key
.
Try removing .type('form')
from your tests, because it will set application/x-www-form-urlencoded
as Content-Type, instead of multipart/form-data
.
