Question

我正在尝试将ReactJS（16.x）用作前端，将PHP（5.x）用作后端。我正在使用Axios调用API。我有一个共享的Linux主机，我正在尝试上载项目。它显示了CORS问题，除了GET之外，任何方法都将永久地移动301，然后分别使用OPTIONS和GET进行相同的调用。

我尝试将CORS添加到PHP代码中，但是它不起作用。

这些是我用来避免CORS问题的标头。

header("Access-Control-Allow-Origin: {$_SERVER['HTTP_ORIGIN']}");
    // header("Access-Control-Allow-Origin: http://temp.mkconsultants.co.in/");
    header("Access-Control-Allow-Credentials: true");
    header('Access-Control-Allow-Methods: GET, PUT, POST, DELETE, OPTIONS');
    header('Access-Control-Max-Age: 1000');
    header('Access-Control-Allow-Headers: Origin, Content-Type, X-Auth-Token , Authorization');

Answer 1

function cors() {

    // Allow from any origin
    if (isset($_SERVER['HTTP_ORIGIN'])) {
        // Decide if the origin in $_SERVER['HTTP_ORIGIN'] is one
        // you want to allow, and if so:
        header("Access-Control-Allow-Origin: {$_SERVER['HTTP_ORIGIN']}");
        header('Access-Control-Allow-Credentials: true');
        header('Access-Control-Max-Age: 86400');    // cache for 1 day
    }

    // Access-Control headers are received during OPTIONS requests
    if ($_SERVER['REQUEST_METHOD'] == 'OPTIONS') {

        if (isset($_SERVER['HTTP_ACCESS_CONTROL_REQUEST_METHOD']))
            // may also be using PUT, PATCH, HEAD etc
            header("Access-Control-Allow-Methods: GET, POST, OPTIONS");         

        if (isset($_SERVER['HTTP_ACCESS_CONTROL_REQUEST_HEADERS']))
            header("Access-Control-Allow-Headers: {$_SERVER['HTTP_ACCESS_CONTROL_REQUEST_HEADERS']}");

        exit(0);
    }

    echo "You have CORS!";
}

使用ReactJS作为前端并使用PHP作为后端来获取后端数据
