如果用户未登录，则无法重定向到登录页面

Question

I have a function that gets executed when a web service is called. 我有一个在调用Web服务时执行的函数。 If the user is not logged in I want to redirect to login page. 如果用户未登录，我想重定向到登录页面。 The front end I'm using is AngularJS. 我正在使用的前端是AngularJS。

The redirection is in the else part. 重定向在else部分。

This is the function: 这是功能：

public function postCustomerGetAction(Request $request) {
$tokenValidationObj = new LoginController();
$isValid = $tokenValidationObj->postValidateUserTokenAction($request);

// print_r($this->customer_id);exit;
// print_r($this->association_id);

// print_r($isValid);exit;
if($isValid == 1){
    $log = new LogController();     
    $log->getLogJsonBody($this->get('logger'),$request);
    $display = new Result();
    try {
        $schema = 'customerGet.json';
        $validation = new InputValidation();
        $validationObj = $validation->dataValidation($request, $schema);
        $getKeyMap = array (
                "_customer_id"      => "customerId",
                "_customer_name"    => "customerName"
        );
        $getFunction = 'svk_apt_get_customer';
        $conObj = new ConnectionController();
        $conObj->beginTransaction();
        $dbres = $conObj->buildQuery($getFunction, $getKeyMap, $validationObj);
        $result = $display->getJsonResult($dbres);
        $conObj->dbCommitTransaction();
    } catch ( Exception $ex ) {
        $log->getExceptionLog($this->get('logger'),$ex);
        $result = $display->getJsonException($ex);
    }
    return $result;
}else{
    $result = $this->container->getParameter('email_template_url');
    // print_r($result);exit;
    return new RedirectResponse($result);
    // header('Location: https://stackoverflow.com');exit;
    // return $this->redirect('https://stackoverflow.com');
}

} }

In the response, I see the following html but it does not redirect to the page I am specifying. 在响应中，我看到以下html，但是它没有重定向到我指定的页面。 The html in response: 响应中的html：

<!DOCTYPE html>
    <html>
        <head>
            <meta charset="UTF-8" />
            <meta http-equiv="refresh" content="0;url=https://stackoverflow.com" />

            <title>Redirecting to https://stackoverflow.com</title>
        </head>
        <body>
            Redirecting to <a href="https://stackoverflow.com">https://stackoverflow.com</a>.
        </body>
    </html>

How do I redirect when the web service is called and user is not logged in? 调用Web服务且用户未登录时如何重定向？

Answer 1

The web service / API should not be redirecting the frontend to another page. Web服务/ API不应将前端重定向到另一个页面。 If you are using Angular to interact with this web service, you should just return a "not logged in" status/flag, and then make Angular do the redirection. 如果您正在使用Angular与该Web服务进行交互，则应仅返回“未登录”状态/标志，然后使Angular进行重定向。

For a creating a custom response, you can refer to: Symfony security return 401 response instead of redirect 对于创建自定义响应，您可以参考： Symfony安全返回401响应而不是重定向

The HTTP Status 401 should be enough. HTTP状态401应该足够了。 More details about this status here: https://httpstatuses.com/401 此处有关此状态的更多详细信息： https : //httpstatuses.com/401

Angular should detect that, and then redirect. Angular应该检测到该错误，然后重定向。
