因为在AngularJS中使用CORS和http身份验证可能会比较棘手，所以我编辑了问题以分享一个经验教训。首先，我要感谢igorzg。他的回答对我很有帮助。场景如下：您想使用AngularJS
$ http服务将POST请求发送到另一个域。获取AngularJS和服务器设置时，需要注意一些棘手的事情。

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，并在请求中输入用户名和密码。

 /**
  *  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'
        }
    });

答案：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。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身份验证以及之后的所有其他操作。

这是在php中使用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();
}
?>
