Game Create Controller createGame函数通过HTML文件被ngClick调用。当函数到达console.log时，$scope.gameData的值是正确的。然而，当请求通过Laravel 5 REST API发送时，请求中没有任何内容。只是为了澄清，我说的是导致问题的这一行:
APIService.postData('game', '', $scope.gameData).then(function (data) {
请求成功返回，因为不需要名称，并且在数据回调中创建并发送了ID。
我已经做了3个其他完整的主题(游戏是一个完整的主题)，其中创建逻辑工作得很好。这个create函数中的逻辑与其他的没有什么不同，但是由于某种原因，name值没有通过REST API发送。
如果您需要更多代码或有任何问题，请告诉我。

您的问题在于您编写数据的方式，以及您将其传递给POST方法的方式。
$scope.gameData = [];
$scope.gameData.name = '';
你的数据被初始化为一个数组，然后你将属性附加到它作为一个对象(是的，数组是一个对象在JS和它的工作!)。然而，当你传递这样一个数组时，angular.toJson()方法并不能很好地工作。它返回一个空数组:[]。
data: angular.toJson(postData); // results in []
解决方案:
$scope.gameData = {};
