解决PHP

我目前正在为uni项目开发PHP REST API,该项目使用通过PhoneGap从移动Web应用程序传递的JSON Web令牌,或者在开发过程中使用我的桌面。

使用ajax将令牌发送到我的服务器页面“ friends / read.php”时,服务器使用

正确获取了Authorization标头
$headers = getallheaders();
$authHeader = $headers['Authorization'];

,但在多次成功运行后停止这样做。此后,将不再提取标题。

我的请求代码如下:

$.ajax({
    url: "http://localhost/chordstruck/api/friends/read.php",
    type: "GET",
    beforeSend: function (request) {
        request.setRequestHeader('Authorization', 'Bearer ' + localStorage.getItem('jwt'));
    },
    datatype: "json",
    success: function (response) {
        console.log(response);
    },
    error: function (jqXHR, textStatus, errorThrown) {
        console.log(jqXHR);
    }
});

奇怪的是,当用die(“ test”)过早地杀死PHP脚本,然后再次删除die()时,服务器将开始为其他几个请求选择Authorization标头。

Read.php:

<?php
error_reporting(E_ALL);
ini_set('display_errors', 'on');
header('Access-Control-Allow-Origin: *');
header('Access-Control-Allow-Methods: GET');
header('Access-Control-Allow-Headers: Origin, Content-Type, Authorization, X-Auth-Token');

$config = require_once '../config/core.php';
require_once '../config/jwt_helper.php';
// get database connection
include_once '../config/database.php';

// instantiate profile object
include_once '../objects/profile.php';

$headers = getallheaders();
$authHeader = $headers['Authorization'];

$token;

if ($authHeader) {

    list($jwt) = sscanf((string)$authHeader, 'Bearer %s');
    if ($jwt) {
        try {

            $key = $config['jwt_key'];
            $token = JWT::decode($jwt, $key, array('HS512'));

        } catch (Exception $e) {
            header('HTTP/1.0 401 Unauthorized');
            exit();
        }
    } else {
        header('HTTP/1.0 400 Bad Request');
        exit();
    }
} else {
    header('HTTP/1.0 400 No Header Found');
    exit();
}

echo "success";
?>

在开发此项目时,我遇到了一个CORS问题,我在.htaccess文件中与上面的标头以及下面的标头对立了:

<IfModule mod_headers.c>
    Header set Access-Control-Allow-Origin "*"
</IfModule>

这可能相关吗?任何帮助/想法将不胜感激!

该问题似乎确实与CORS有关,并且在尝试了多种方法之后,以下解决方案现在正在起作用。

将read.php中的标头替换为:

// Allow from any origin
if (isset($_SERVER['HTTP_ORIGIN'])) {
    // Decide if the origin in $_SERVER['HTTP_ORIGIN'] is one
    // you want to allow, and if so:
    header("Access-Control-Allow-Origin: {$_SERVER['HTTP_ORIGIN']}");
    header('Access-Control-Allow-Credentials: true');
    header('Access-Control-Max-Age: 86400');    // cache for 1 day
}

// Access-Control headers are received during OPTIONS requests
if ($_SERVER['REQUEST_METHOD'] == 'OPTIONS') {

    if (isset($_SERVER['HTTP_ACCESS_CONTROL_REQUEST_METHOD']))
        // may also be using PUT, PATCH, HEAD etc
        header("Access-Control-Allow-Methods: GET, POST, OPTIONS");         

    if (isset($_SERVER['HTTP_ACCESS_CONTROL_REQUEST_HEADERS']))
        header("Access-Control-Allow-Headers: {$_SERVER['HTTP_ACCESS_CONTROL_REQUEST_HEADERS']}");

    exit(0);
}

信用归功于slashingweapon,后者用它来回答CORS with php headers
