描述

This function can be used to get the cross-origin type set for HTML5 games and will return a string (on all other platforms an empty string "" will be returned).

语法：

http_get_request_crossorigin();

返回：

String（字符串）

例如：

if string_lower(http_get_request_crossorigin()) != "use-credentials"
    {
    http_set_request_crossorigin("use-credentials");
    }
sprite_add("sprites/player_outfit_1.png", 0, false, false, 0, 0);

The above code will first check the currently set cross origin type and if it is not "use-credentials" then it is set to "use-credentials" and then a sprite is added from a file.
