PHP 开启跨域

1.普通直接开启跨域

?

1 2 3 4 5 6 7 8 9

function not_region($boolean) {     if($boolean){         header('Access-Control-Allow-Origin:*');         header( 'Access-Control-Allow-Methods: GET,POST, OPTIONS' );         header( 'Access-Control-Allow-Headers: Origin,Content-Type, Accept, Authorization, X-Request-With' );         header( 'Access-Control-Allow-Credentials: true');     } }

lumen使用 CORS 解决跨域问题


3.使用console.log 测试跨域：

?

1 2 3 4 5 6 7

var xhr = new XMLHttpRequest(); xhr.open('GET', 'https://xxx.com'); xhr.send(null); xhr.onload = function(e) {     var xhr = e.target;     console.log(xhr.responseText); }
