AngularJS $http、CORS 和 http 身份验证

Question

因为在 AngularJS 中使用 CORS 和 http 身份验证可能很棘手，所以我编辑了这个问题来分享一个经验教训。首先我要感谢igorzg。他的回答对我帮助很大。场景如下:您想要使用 AngularJS $http 服务将 POST 请求发送到不同的域。在获取 AngularJS 和服务器设置时，有几个棘手的事情需要注意。

第一:在您的应用程序配置中，您必须允许跨域调用

/**
 *  Cors usage example. 
 *  @author Georgi Naumov
 *  gonaumov@gmail.com for contacts and 
 *  suggestions. 
 **/ 
app.config(function($httpProvider) {
    //Enable cross domain calls
    $httpProvider.defaults.useXDomain = true;
});

第二:您必须指定 withCredentials: true 以及用户名和密码要求。

 /**
  *  Cors usage example. 
  *  @author Georgi Naumov
  *  gonaumov@gmail.com for contacts and 
  *  suggestions. 
  **/ 
   $http({
        url: 'url of remote service',
        method: "POST",
        data: JSON.stringify(requestData),
        withCredentials: true,
        headers: {
            'Authorization': 'Basic bashe64usename:password'
        }
    });

第三: 服务器设置。您必须提供:

/**
 *  Cors usage example. 
 *  @author Georgi Naumov
 *  gonaumov@gmail.com for contacts and 
 *  suggestions. 
 **/ 
header("Access-Control-Allow-Credentials: true");
header("Access-Control-Allow-Origin: http://url.com:8080");
header("Access-Control-Allow-Methods: GET, POST, PUT, DELETE, OPTIONS");
header("Access-Control-Allow-Headers: Origin, X-Requested-With, Content-Type, Accept, Authorization");

对于每个请求。当您收到 OPTION 时，您必须通过:

/**
 *  Cors usage example. 
 *  @author Georgi Naumov
 *  gonaumov@gmail.com for contacts and 
 *  suggestions. 
 **/ 
if($_SERVER['REQUEST_METHOD'] == 'OPTIONS') {
   header( "HTTP/1.1 200 OK" );
   exit();
}

HTTP 身份验证和其他一切都在这之后。

这里是使用 php 服务器端的完整示例。

<?php
/**
 *  Cors usage example. 
 *  @author Georgi Naumov
 *  gonaumov@gmail.com for contacts and 
 *  suggestions. 
 **/ 
header("Access-Control-Allow-Credentials: true");
header("Access-Control-Allow-Origin: http://url:8080");
header("Access-Control-Allow-Methods: GET, POST, PUT, DELETE, OPTIONS");
header("Access-Control-Allow-Headers: Origin, X-Requested-With, Content-Type, Accept, Authorization");

if($_SERVER['REQUEST_METHOD'] == 'OPTIONS') {
   header( "HTTP/1.1 200 OK" );
   exit();
}


$realm = 'Restricted area';

$password = 'somepassword';

$users = array('someusername' => $password);


if (isset($_SERVER['PHP_AUTH_USER']) == false ||  isset($_SERVER['PHP_AUTH_PW']) == false) {
    header('WWW-Authenticate: Basic realm="My Realm"');

    die('Not authorised');
}

if (isset($users[$_SERVER['PHP_AUTH_USER']]) && $users[$_SERVER['PHP_AUTH_USER']] == $password) 
{
    header( "HTTP/1.1 200 OK" );
    echo 'You are logged in!' ;
    exit();
}
?>

不，您不必放置凭据，您必须在客户端放置 header ，例如:

 $http({
        url: 'url of service',
        method: "POST",
        data: {test :  name },
        withCredentials: true,
        headers: {
                    'Content-Type': 'application/json; charset=utf-8'
        }
    });

并且在服务器端，您必须将 header 添加到这是 Nodejs 的示例:

/**
 * On all requests add headers
 */
app.all('*', function(req, res,next) {


    /**
     * Response settings
     * @type {Object}
     */
    var responseSettings = {
        "AccessControlAllowOrigin": req.headers.origin,
        "AccessControlAllowHeaders": "Content-Type,X-CSRF-Token, X-Requested-With, Accept, Accept-Version, Content-Length, Content-MD5,  Date, X-Api-Version, X-File-Name",
        "AccessControlAllowMethods": "POST, GET, PUT, DELETE, OPTIONS",
        "AccessControlAllowCredentials": true
    };

    /**
     * Headers
     */
    res.header("Access-Control-Allow-Credentials", responseSettings.AccessControlAllowCredentials);
    res.header("Access-Control-Allow-Origin",  responseSettings.AccessControlAllowOrigin);
    res.header("Access-Control-Allow-Headers", (req.headers['access-control-request-headers']) ? req.headers['access-control-request-headers'] : "x-requested-with");
    res.header("Access-Control-Allow-Methods", (req.headers['access-control-request-method']) ? req.headers['access-control-request-method'] : responseSettings.AccessControlAllowMethods);

    if ('OPTIONS' == req.method) {
        res.send(200);
    }
    else {
        next();
    }


});
