[如果您使用angular将ajax请求发送到本地node.js服务器，则应将access-control-allow-origin放在接受ajax请求（即localhost）的目标服务器上，不要将其与ajax请求一起发布。 >

XMLHttpRequest无法加载http://127.0.0.1:1337/。所请求的资源上没有“ Access

我尝试使用Angular.js和本地运行的Node.js服务器从HTML页面发送和接收数据

app.controller("MainController", function MainController($scope, $http){		
	$scope.postIt = function() {
		//alert("posting...");
		$http.post('http://127.0.0.1:1337/', {msg:'hello from Angular.js!'})
		.success(function onSuccess(response){
	        console.log(response);
	        $scope.$apply(function(){
	            $scope.testData = JSON.parse(response);
	            console.log($scope.testData);
	        });
	    }).error(function onError(){
	        console.log("AJAX failed!");
	    });
    };
});
