Cross-domain access via JSONP in PHP laravel framework __div

The parameter transfer under the same domain name is easy to implement, but there are some limitations in Cross-domain domain. Of course, I can search a lot of introduction posts, here I jsonp this one-way cross-domain way to summarize, and attach a small example.

Problem Description:

Because of the development on the server, use the unused port number to distinguish between different projects.

Implementation 192.168.1.10:8888 can invoke parameters on the 8889 project. (Originating from single sign-on, required for verification)

192.168.1.10:8888 End:

1. Controller implementation:

Public function test ()
{return
    view (' Test ');
}

2. ' test.blade.php ':

 

192.168.1.10:8889 End:
1.controller implementation:

Public function test ()
{
    \debugbar::d isable ();
    $callback = Input::get (' callback ');
    $arr =array (' A ' => ' Panhe ', ' B ' => ' Dada ');
    return $callback. " ('". Json_encode ($arr). "')"; 
    return response ($callback.) ('". Json_encode ($arr). "')")->withcookie (' Test ', ' authverify ', 10000000, '/')
