今天在看看node request API 时，发现requset在上传表单时可以通过下面两种方式：这两个方法有什么区别与联系，在实际开发中，应该如何选择？ 1. POST data to a JSON REST API

var options = { method: ‘POST’, uri: ‘http://api.posttestserver.com/post’, body: { some: ‘payload’ }, json: true // Automatically stringifies the body to JSON };

2. POST like HTML forms do

var options = { method: ‘POST’, uri: ‘http://posttestserver.com/post.php’, formData: { // Like <input type=“text” name=“name”> name: ‘test.jpg’, // Like <input type=“file” name=“file”> file: { value: fs.createReadStream(‘test/test.jpg’), options: { filename: ‘test.jpg’, contentType: ‘image/jpg’ } } }, headers: { /* ‘content-type’: ‘application/x-www-form-urlencoded’ */ // Is set automatically } };
