向控制器发送数据并尝试进行 API 调用时出现 500 内部服务器错误

Question

我正在尝试进行 $.ajax 调用并将一些数据发送到 cakephp 中的控制器并进行 API 调用，我不断收到 500 内部服务器错误。

jquery 文件

$.ajax({
type: 'POST',
url: '/src/Controller/PagesController/createLinks',
data: {
    spotifyLink: spotifyLink,
    accessToken: access_token,
    boardID: boardID,
},
dataType: 'json',
complete: function (response) {
    console.log("data coming back from pagesController.php" + response.responseText);
},
error: function (jqXHR, textStatus, errorThrown) {
    console.log(jqXHR, textStatus, errorThrown);
}
});

控制器文件

public function createLinks() {

    if ($this->request->is('ajax') && $this->request->is('post') ){

        $link = $_POST['spotifyLink'];
        $token = $_POST['access_token'];
        $boardID = $_POST['boardID'];

        $apiLink = 'https://api.linkfire.com/campaigns/boards/'.$boardID.'/links';

        $body = array("baseUrl" => $link);

        $http = new Client();
        $response = $http->post($apiLink, $body,
            ['headers' =>['Authorization' => 'Bearer '.$token, 
                          'content-type' => 'application/json']]);
        $json = $response->json;
        echo ($body);
        return $response;
    }

在我的路由器文件中我有

$routes->connect('/src/Controller/PagesController/createLinks', ['controller' => 'Pages', 'action' => 'createLinks']);

这是我遇到的错误

jquery-3.3.1.min.js:2 POST http://localhost:8765/src/Controller/PagesController/createLinks 500 (Internal Server Error)

请注意，数据会打印在控制台和响应正文中，我有以下内容

{"message":"An Internal Error Has Occurred.","url":"\/src\/Controller\/PagesController\/createLinks","code":500}

日志文件显示以下错误：

Error: [Cake\Routing\Exception\MissingControllerException] Controller class Js could not be found.

请求URL：/js/MDB/js/bootstrap.min.js.map

2018-07-12 07:23:17 Error: [LogicException] Controller actions can only return Cake\Http\Response or null.

请求URL：/src/Controller/PagesController/createLinks 推荐人 URL：http://localhost:8765/

任何帮助将不胜感激。

Answer 1

ajax调用“/src/Controller/PagesController/createLinks”中的url应该是 "pages/create-links".

另外，看看 json 浏览量：https://book.cakephp.org/3.0/en/views/json-and-xml-views.html
