AngularJS实现ajax请求的方法

var myModule = angular.module("HelloAjax",[]);

myModule.controller("HelloAjax",["$scope","$http",function HelloAjax($scope,$http){

  /*

  $scope.users=[{'username':"zhangsan","email":"zs@11.com"},

    {'username':"zhangsan2","email":"zs@22.com"},

    {'username':"zhangsan3","email":"zs@33.com"}];

  */

  $scope.get_more = function(){

    $http({

        method: "POST",

        url: "./ajax.php",

        data:{'username':$scope.username,

           'email':$scope.email

          }

      }).

      success(function(data, status) {

       //$scope.status = status;

        $scope.users = data;

      }).

      error(function(data, status) {

       //$scope.data = data || "Request failed";

       //$scope.status = status;

     });

   }

}]);

<?php

//获取参数

$data = file_get_contents("php://input");

$user = json_decode($data);

//查询数据库

$conn = mysql_connect("localhost","root","");

mysql_SELECT_db("test");

$sql ="SELECT username,email from users ";

$res = mysql_query($sql,$conn);

$users = array();

while($row = mysql_fetch_assoc($res)){

  $users[] = $row;

}

//当然这里简化了插入数据库

$users[] = array('username'=>$user->username,

         'email'=>$user->email);

//返回数据库

echo json_encode($users);
