在PUT中请求如何在codeigniter 3中检索数据

Question

I'm sending data as http PUT request. Using Postman I have chosen form-data as option to send data as I want to send(upload) file as well,along with other necessary data.

I have chosen a csv file and a field with name(key) as "asd". In output window data is displayed as below :

So my question is : how to retrieve or receive the data in codeigniter 3 with key name asd and input type file's key name fil?

I tried:

$this->input->raw_input_stream('asd');
$this->input->raw_input_stream('fil');

But it didn't work.

If it is a HTTP request you could use:

file_get_contents('php://input')

It will return the HTTP body.
