AngularJS：PUT使用URL发送数据，但不作为JSON数据发送

我正在共享我的代码库中的代码，该代码在按照@lucuma的建议进行更改后有效

The UserService looks like

angular.module('userServices', ['ngResource']).factory('User', function($resource) {  return $resource('/users/:userId',      // todo: default user for now, change it      {userId: 'bd675d42-aa9b-11e2-9d27-b88d1205c810'},      {update: {method: 'PUT', data:{}, isArray: false}} // add data instead of params  );});

and ProfileController looks like

function ProfileController($scope, User) {    $scope.profile = {};    $scope.user = User.get();    $scope.save = function () {        // I was using $scope.user.$update before which was wrong, use User.update()        User.update($scope.profile, function (data) {     $scope.user = data; // since backend send the updated user back });    }

进行这些更改后，我在Chrome中的“网络”标签符合预期

Request URL:http://localhost:5000/users/bd675d42-aa9b-11e2-9d27-b88d1205c810Request Method:PUTStatus Code:200 OKRequest Payload:{"day_in_month":25}
