php - larave5.3 options 请求

Question

使用laravel5.3做接口，前端跨域访问。
当前端发起请求时，浏览器会先发起options请求，就是cors跨域的问题，先是请求一个test.php,请求是成功的

<?php 
header("Access-Control-Allow-Origin: *");
header("Access-Control-Allow-Methods: PUT, GET, POST, DELETE, OPTIONS");
header("Access-Control-Allow-Headers: content-type,authorization");
$arr=['1','2'];

echo json_encode($arr);

?>    

然后请求laravel5.3的接口，options请求没有返回设定的header

Route::any('/user', function (Request $request) {
    header("Access-Control-Allow-Origin: *");
    header("Access-Control-Allow-Methods: PUT, GET, POST, DELETE, OPTIONS");
    header("Access-Control-Allow-Headers: content-type,authorization");
    return [$request->user()];
})->middleware('auth:api');

Answer 1

不要直接写在路由内，可以考虑使用中间件，这个应该可以帮到你

Answer 2

参考这个：https://gist.github.com/shell...

在public里面加上

$response->header('Access-Control-Allow-Origin', '*')
    ->header('Access-Control-Allow-Methods', 'POST, GET, OPTIONS, PUT, DELETE')
    ->header('Access-Control-Allow-Headers', 'Content-Type, Accept, Authorization, X-Requested-With, Origin')->send();

Answer 3

laravel里面尽可能不要调用各种请求和响应相关的php函数，而是使用他本身封装的request和response对象
