我有 angularjs 发布请求：

var loginApp = angular.module("loginApp",[]);
loginApp.controller('loginController', function 
loginController($scope,$http,$window) {

    $scope.submitHandle = function() {
        var req = {
            url: '../login.php',
            method: 'POST',
            data: {
                username: $scope.Username,
                password: $scope.Userpassword,
            }

        };
        $http(req).then(function success(response) {
            var data = response.data;
            if(data.returnCode ==200) {
            alert("Welcome : "+ data.username);
                $window.location = '../webapp/html/user.html';
            }
            else {
                alert("User does not exist");
            }
    }, function(response) {
        alert("Error on server side");
    });
    }
});

这个请求被传递给 login.php，如下所示：

<?php
$servername = "localhost";
$username1 = "root"; 
$password1 = "abcd";

try {
    $conn = new PDO("mysql:host=$servername;dbname=ITC_MANAGEMENT", $username1, $password1);
    $conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
$postdata=file_get_contents("php://input");
$request=json_decode($postdata,true);
$username=$request->username;
$password=$request->password;
$stmt = $conn->prepare("SELECT UserId, Password from USER_INFO WHERE UserID='".$username."' && Password='".$password."'");
$stmt->execute();
$row = $stmt->rowCount();
if ($row > 0){
$json_array=array();
   $json_array['returnCode']=200;
     $json_array['username']="user1";

          echo  json_encode($json_array);

} else{
   $json_array=array("returnCode"=>201,"username"=>"user1");

  echo json_encode($json_array);
}
    }
catch(PDOException $e)
    {
    echo "Connection failed: " . $e->getMessage();
    }
?>

现在，当我检查 response.data 时，它显示如下：

"<br />
<font size='1'><table class='xdebug-error xe-notice' dir='ltr' border='1' cellspacing='0' cellpadding='1'>
<tr><th align='left' bgcolor='#f57900' colspan="5"><span style='background-color: #cc0000; color: #fce94f; font-size: x-large;'>( ! )</span> Notice: Trying to get property of non-object in C:\wamp64\www\itc\login.php on line <i>11</i></th></tr>

</table></font>
{"returnCode":200,"username":"user1"}"

正如所见，我在期待，response.data = {"returnCode":200,"username":"user1"}"但我不知道为什么会出现 HTML。这只是一个简单的测试，看看 post 是否有效。我是 php 和 angular 的新手，在这一点上卡住了。任何帮助将不胜感激。

您应该尝试处理 PHP 如何向您的应用程序客户端抛出错误。

<?php
// Turn off error reporting
error_reporting(0);

// Report runtime errors
error_reporting(E_ERROR | E_WARNING | E_PARSE);

// Report all errors
error_reporting(E_ALL);

// Same as error_reporting(E_ALL);
ini_set("error_reporting", E_ALL);

// Report all errors except E_NOTICE
error_reporting(E_ALL & ~E_NOTICE);
?>
