thinkphp integration push

When using thinkphp, put the downloaded push sdk into the vendor directory. How to reference it into the project?
vendor('iGT.IGt.Push');
Why can't it be referenced?

<code>vendor("IGT.IGT", '' ,'.Push.php');</code>

Yours is actually loading the Vendor/iGT/IGT/Push.php file

Try how to change the file extension

<code>vendor('iGT.IGt', dirname(__FILE__), '.Push.php')；</code>

Or change the file name, do not appear in the file name .

It is recommended to use namespace to introduce class, and it is not recommended to use vendor function

new VendoriGTIGTPush(); Isn’t this okay?
