本地没有'Access-Control-Allow-Origin'标头错误测试应用程序。 （超薄+ Phonegap应用程序）

Question

我有一个带Slim Framework的小服务器（index.php）：

$app = new \Slim\Slim();

$corsOptions = array(
    "origin" => "*",
    "exposeHeaders" => array("Content-Type", "X-Requested-With", "X-authentication", "X-client"),
    "allowMethods" => array('GET', 'POST', 'PUT', 'DELETE', 'OPTIONS')
);
$cors = new \CorsSlim\CorsSlim($corsOptions);

$app->add($cors);

$app->post('/foo', function () use ($app) {
    ...
    echo "foo";
});

当我尝试使用Ionic（phonegap app）从我的应用程序（手机应用程序）攻击post方法时，我收到此消息：

  

XMLHttpRequest无法加载http://MY_IP/~FOLDER/foo。回应   预检请求未通过访问控制检查：否   请求中存在“Access-Control-Allow-Origin”标头   资源。因此不允许来源“http://192.168.0.157:8100”   访问。响应的HTTP状态代码为404.

代码：

$http.post(rest_service_url + '/foo', {
                    data: ...
                }).then(
                    function(res){
                        console.log("OK");
                    },
                    function(err){
                        console.log("ERROR", err);
                    }
                );

我在互联网上测试了这些解决方案，但是无人工作：

使用CorsSlim：

$corsOptions = array(
    "origin" => "*",
    "exposeHeaders" => array("Content-Type", "X-Requested-With", "X-authentication", "X-client"),
    "allowMethods" => array('GET', 'POST', 'PUT', 'DELETE', 'OPTIONS')
);
$cors = new \CorsSlim\CorsSlim($corsOptions);

将其放入.htaccess

Header set Access-Control-Allow-Origin "*"
Header set Access-Control-Allow-Methods: "GET,POST,OPTIONS,DELETE,PUT"

将此放在index.php

之上

header('Access-Control-Allow-Origin: *');
header('Access-Control-Allow-Headers: Content-Type');
header('Access-Control-Allow-Methods: GET, PUT, POST, DELETE, OPTIONS');

在Slim创建后使用此功能：

$app->options('/(:name+)', function() use($app) {                  
    $response = $app->response();
    $app->response()->status(200);
    $response->header('Access-Control-Allow-Origin', '*'); 
    $response->header('Access-Control-Allow-Headers', 'Content-Type, X-Requested-With, X-authentication, X-client');
    $response->header('Access-Control-Allow-Methods', 'GET, POST, PUT, DELETE, OPTIONS');
 });
