AngularJS $ http,CORS和http身份验证

Question

因为在AngularJS中使用CORS和http认证可能很棘手,所以我编辑了这个问题,分享了一个学到的课程.首先,我要感谢igorzg.他的回答对我很有帮助.方案如下:您希望使用AngularJS $ http服务将POST请求发送到其他域.获取AngularJS和服务器设置时需要注意几个棘手的事情.

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并将用户名和密码指定为请求.

 /**
  *  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'
        }
    });

Тhird:服务器设置.你必须提供:

/**
 *  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此之后.

这是使用php的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,你不必放置凭证,你必须在客户端放置标题,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,你必须将标题放到这是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();
    }


});
