我在echo中看到了我所有的html

I see all my html in echo

我将数据作为数组发送到php，并使用echo进行检查。好的，它有效。我看到了我的用户名。但是当我添加$pdo时，我会看到我所有的html（我不想看到）。这是怎么回事？

这是我的javascript

var appAdmin=angular.module('appLogin',[]);
appAdmin.service('loginService',
    function($http) {
        this.submitLogin=function(username,password){
            return $http({method:'POST',
                url: "php/checkLogin.php",
                data: {
                    username: username,
                    pass: password
                },
                headers: { 'Content-Type': 'application/x-www-form-urlencoded' }
            }); //use $http() here.
        }
    });
appAdmin.controller('LoginCtrl',function($scope,loginService){
    $scope.user={};
    $scope.submitLogin=function(){
        loginService.submitLogin($scope.user.username,$scope.user.password)
            .then(function(data,status,config,headers){
                debugger;
                console.log('Response from server: '+data.data);
            },
                function(data,status,config,headers){
                    console.log('Some error occurred!'); //called in case of error
                }
            )
    }
});

这是我的PHP

<?php
    $postdata = file_get_contents("php://input");
    $request = json_decode($postdata);
    @$username = $request->username;
    @$password = $request->password;
    $pdo = new PDO('mysql:host=localhost;dbname=subscribers', 'tuviak',    'tuvik1002') ;
    echo htmlspecialchars($username, ENT_QUOTES, 'UTF-8'); //this will go back under "data" of angular call.
?>

这是我的html:

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Login</title>
    <link rel="stylesheet" type="text/css" href="../css/styleAdmin.css">

<body ng-app="appLogin" ng-controller="LoginCtrl">

        <input type="text" name="password" ng-hide="true">
        <div id="loginBox">
            <div class="lineBox">
                <span class="label">Username</span>
                <input type="text"   name="username" autocomplete="off" ng-model="user.username" ng-required="true"  ng-minlength="6" ng-maxlength="8" ng-pattern="/[0-9a-z]/i">
                <span class="error-message" ng-show="frmLogin.username.$dirty&& frmLogin.username.$error" ng-hide="frmLogin.username.$dirty&& frmLogin.username.$valid">
                    The Username is Mandatory
                </span>
            </div>
            <div class="lineBox">
                <span class="label">Password</span>
                <input type="password"  autocomplete="off" name="psd" ng-model="user.password" ng-required="true" ng-minlength="6" ng-maxlength="8" ng-pattern="/[0-9a-z]/i">
                <span class="error-message" ng-show="frmLogin.psd.$dirty&&frmLogin.psd.$error" ng-hide="frmLogin.psd.$dirty&& frmLogin.psd.$valid">
                    The password is Mandatory
                </span>
            </div>
            <div class="lineBox">
                <input type="button" value="submit" id="submit" ng-disabled="frmLogin.$invalid" ng-click="submitLogin()">
            </div>
        </div>
    </form>
    <script src="../lib/angular.js"></script>
    <script src="../js/admin.js"></script>
</body>
</html>

谢谢你的帮助！

我不确定你的PHP是如何构建的——你是否只显示了它的一个小摘录，或者它是否与javascript在同一页上。如果php在同一个页面上，并且您正在（通过ajax）发布到同一个脚本，那么使用ob_clean()将清除在它到达php 之前创建的任何输出缓冲区

<?php
    if( $_SERVER['REQUEST_METHOD']=='POST' ){
        ob_clean();
        /* your php code - with PDO stuff */
        echo htmlspecialchars( $username, ENT_QUOTES, 'UTF-8' );
        exit();
    }
?>
<html>
    <head>
        <title>Login</title>
        <script>/* Your angularjs code */</script>
    </head>
    <body>
    </body>
</html>

我的问题的解决方案非常简单：返回的html是对连接状态中php错误的解释。
