本文介绍了如何使用Node.js中的两个流行库：needle和request来上传包含图片等二进制数据的表单。通过示例代码展示了如何配置POST请求并处理响应。

1、needle

npm install needle

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)
});

2、request

npm install request

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);
});
