node 实现把文件上传到另一台服务器

var needle = require(‘needle‘);var data = { ???foo: ‘bar‘, ???image: { file: ‘./images/2.png‘, content_type: ‘image/png‘ }}needle.post(‘http://xxx/upload_v_article‘, data, { multipart: true }, function(err, resp, body) { ???// needle will read the file and include it in the form-data as binary ???console.log(err, resp, body)});

var request = require(‘request‘);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(‘./images/2.png‘),};request.post({url:‘http://xxx/upload_v_article‘, formData: formData}, function optionalCallback(err, httpResponse, body) { ???if (err) { ???????return console.error(‘upload failed:‘, err); ???} ???console.log(‘Upload successful! ?Server responded with:‘, body);});
