将curl GET转换为javascript fetch

curl -X GET 
-H "X-Parse-Application-Id:1231231231" 
-H "X-Parse-REST-API-Key: 131231231" 
-G 
--data-urlencode 'where={"uid":"12312312"}' 
https://api.parse.com/1/classes/birthday`

但我正在努力将其转换为javascript,使用下面的代码我会得到状态为200的响应.我假设错误是将data-urlencode转换为数据：

var getObject = function {
    var url = "https://api.parse.com";
    url += '/1/classes/birthday';

    fetch(url,{
        method: 'GET',headers: {
            'Accept': 'application/json','X-Parse-Application-Id': '12122','X-Parse-REST-API-Key': '12121','Content-Type': 'application/json',},data: '{"where":{"uid":"12312312"}}'

    })
    .then(function(request,results) {
        console.log(request)
        console.log(results)
    })
}

谢谢！
