当从邮递员Chrome应用程序或移动设备发出请求时，$ _POST / $ _ REQUEST在Web服务上为空

Question

$_POST and $_REQUEST are empty in the web service when a request is made from the postman chrome app, using curl or from mobile.

The serialized post is not blank. It has the input parameter name, but no value. var_dump is also showing blank array.

I am getting parameters with a GET request and when the request is made through a webpage html form.

I am using codeigniter.
