I am trying to receive json message from servlet based on angular js, but
it always fails.
I am using the $http.post, but seems it does not work, could someone help
me on that?
Here is my servlet code:
public class HelloWorld extends HttpServlet {
@Override
protected void doPost(HttpServletRequest request, HttpServletResponse
response) throws ServletException, IOException {
response.setContentType("application/json");
PrintWriter out = response.getWriter();
JSONObject jsonObject = new JSONObject();
jsonObject.put("field_name", "hahaha");
out.print(jsonObject);}
Here is my js:
var sandBoxApp = angular.module('sandboxApp', [])
sandBoxApp.controller('SandBoxCtrl', function ($scope, $http){
$scope.heads = ['Field name', 'Original value', 'Processed value'];
$scope.myData = {};
$scope.myData.doClick = function(item, event) {
var responsePromise = $http.post("HelloWorld");
responsePromise.success(function(data, status, headers, config) {
$scope.fromServer = data;
});
responsePromise.error(function(data, status, headers, config) {
alert("AJAX failed!");
});
}});
