Answer 3

可以使用requset模块做相应的处理即可；
官方文档写的很清楚。
var formData = {
// Pass a simple key-value pair
my_field: 'my_value',
// Pass data via Buffers
my_buffer: new Buffer([1, 2, 3]),
// Pass data via Streams
my_file: fs.createReadStream(__dirname + '/unicycle.jpg'),
// Pass multiple values /w an Array
attachments: [

fs.createReadStream(__dirname + '/attachment1.jpg'),
fs.createReadStream(__dirname + '/attachment2.jpg')

],
// Pass optional meta-data with an 'options' object with style: {value: DATA, options: OPTIONS}
// Use case: for some types of streams, you'll need to provide "file"-related information manually.
// See the form-data README for more information about options: https://github.com/form-data/...
custom_file: {

value:  fs.createReadStream('/dev/urandom'),
options: {
  filename: 'topsecret.jpg',
  contentType: 'image/jpg'
}

}
};
request.post({url:'http://service.com/upload', formData: formData}, function optionalCallback(err, httpResponse, body) {
if (err) {

return console.error('upload failed:', err);

}
console.log('Upload successful! Server responded with:', body);
});
