is_int() cannot check $_GET in PHP?

阅读更多关于 is_int() cannot check $_GET in PHP?

问题 Here is my code: <?php $id = $_GET["id"]; if (is_int($id) === FALSE) { header('HTTP/1.1 404 Not Found'); exit('404, page not found'); } ?> It always enters inside the if. 回答1: is_int checks that the data type is an integer, but everything in $_GET will be a string. Therefore, it will always return false . In a pinch, you could cast to an integer and then check for != 0. $id = isset($_GET['id']) ? (int) $_GET['id'] : null; if (!$id) { // === 0 || === null header('HTTP/1.1 404 Not Found'); exit

I'm trying to get pictures from webcams.

Axios/XMLHttpRequest is sending GET instead of POST in production environment

阅读更多关于 Axios/XMLHttpRequest is sending GET instead of POST in production environment

问题 I am running into a very strange issue. We are putting an app into production and one of the POST request is turning into a POST followed directly by a GET request to the same URL and the POST is never received in the backend (Laravel). In the chrome network tab it just looks like just a GET but with Burpsuite we can see the POST request. The code responsible async store() { // This prints post console.log(this.method()); await this.form[this.method()]('/api/admin/users/' + (this.isUpdate() ?

$_GET as parameters in PHP functions

阅读更多关于 $_GET as parameters in PHP functions

I have the same question but...I'm redirecting the user depending on an if statement using headers to a dynamic page that is constructed through a function. For that function to work properly, it needs the parameters passed in the GET portion of the headers. According to what to the answers provided, this is a bad practice. What way should I be doing it? function page($title,$msg){ $title = $_GET['title']; $msg = $_GET['msg']; echo '<h1>'.$title.'</h1>'; echo '<p>'; switch($msg){ case 1: echo 'dwasdwadawdwadwa'; break; case 2: echo 'wasdadwadwdad'; break; default: echo 'wadasdasd'; break; }

REST how to pass values containing “/” as path parameter in the URI?

阅读更多关于 REST how to pass values containing “/” as path parameter in the URI?

I am developing a Client using HttpClient in Java to access a REST Application. In this i want to pass two parameters name(value="Kiran") and address(Value="5th Corner/Road") as path parameters . Sample url:-http://localhost:port/rest/name/Kiran/address/5th Corner/Road But as address contains "/" as value, its not taking the actual value. Is there a way to handle "/" while accessing REST applications from Java. Any help is appreciated. Use java.net.URLEncoder to encode the query parameters. 来源： https://stackoverflow.com/questions/12350768/rest-how-to-pass-values-containing-as-path-parameter-in

Why do we need HTTP GET? Is there anything that can't be achieved by HTTP POST?

阅读更多关于 Why do we need HTTP GET? Is there anything that can't be achieved by HTTP POST?

As far as I know what GET can do, the same can be achieved by POST. So why was GET required in first place while defining HTTP protocol. If GET is only for fetching the resource, people can still update resources by sending the parameters values in URL. Why this loophole? Or the guy who did the coding on server side to update the resource on GET request has written a bad code? Practically, no browser implements POSTing by clicking links (without intercepting the click event in JavaScript), nor bookmarking POST data. Furthermore, semantically POST and GET serve different purposes. One is for
