	User.updateProfile = function (uid, data, callback) {
		var fields = ['username', 'email', 'fullname', 'website', 'location',
			'groupTitle', 'birthday', 'signature', 'aboutme'];

		var updateUid = data.uid;
		var oldData;

		console.log(uid)  //28
		console.log(updateUid) //undefined

curl -X PUT -H  "Authorization: Bearer d1a81c3f-b0d4-4bc1-a307-dbed9aa5fbe" --data "uid=28&username=修改用户名测试" http://localhost:4567/api/v1/users/28
{
    "code": "ok",
    "payload": {}
}

"uid=28&username=修改用户名测试" 

The problem is solved！（是我的问题还是文档的问题？？？）@julian
