我正在处理Azure移动服务推送通知，我正在尝试发送特定注册ID的推送通知 . 我有以下脚本，有人可以告诉我如何更新此JavaScript以便它可以正常工作：
exports.post = function(request, response) {
var push = request.service.push;
var token="APA91bG7pOV2jLiSiSujNS4Gg_Q##################";
var mes = "Hellooooo";
var payload = '{"data":{"message" : "Testing"}}';
push.gcm.send(null,payload,{
success: function(pushResponse) {
console.log("Sent push:", pushResponse, payload);
request.respond();
},
error: function (pushResponse) {
console.log("Error Sending push:", pushResponse);
request.respond(500, { error: pushResponse });
}
});
};
