Avoid inadvertently sending an HTTP OPTIONS request when including an authentication token in an Angular HTTP request

Encountering a problem with CORS while attempting to execute a GET request with an Authorization token, but running into issues with OPTIONS. Seeking solutions on how to avoid sending OPTIONS when making a GET request to another server.

$http({
        url: request_data.url,
        type: request_data.method,
        withCredentials: true,
        headers: {
            'Authorization': localStorage.getItem('Auth'),
            'Content-Type': 'application/json; charset=utf-8'
        },
        crossDomain: true
    }).then(function(response) {
        //process your data here
        vm.prodData = response.data;
        console.log(response.data);
    });

Unable to send the request due to the CORS issue, likely related to the Authorization header.

Answer №1

There is a limitation.

Cross-origin requests cannot include "Authorization" headers without proper permission as they are considered unsafe.

A preflight OPTIONS request is necessary to obtain the required authorization for such requests.

If you are attempting something out of the ordinary that poses a potential risk, it is essential to adjust the target server settings to allow the browser to proceed with the request.

Answer №2

When attempting a CORS request, the process involves sending an OPTIONS request first to verify if the requests are permitted. This issue must be addressed on the server side. For example, in PHP, you can handle it like this:

if($_SERVER['REQUEST_METHOD'] == 'OPTIONS') {
    header( "HTTP/1.1 200 OK" );
    exit();
}

By implementing this code, when the client sends an OPTIONS request, it will automatically receive a 200 OK response before proceeding with the correct request (such as GET or POST).
