Solution:

• In postmane first create new request.

• Then select POST as request and insert your localhost URL ( eg. http://localhost/project_folder_name/YOUR_FILE_NAME.php )

• In below tab select Body.

• In Body select raw to pass request data.

• Pass below json

{ "mobile":"asdsad", "password":"asdasd" }

• click send button you will get result
