Data calling method and device and computer readable storage medium

The invention provides a data calling method and device and a computer readable storage medium. The data calling method comprises the steps that an RPC client obtains a current client handle in current data calling parameters; the RPC client searches a current universal unique identification code corresponding to the current client handle in a plurality of pre-constructed second key value pairs according to the current client handle; the RPC client side sends the found current universal unique identification code to the RPC server side; the RPC server side searches a target server side handle corresponding to the current universal unique identification code in a plurality of pre-constructed first key value pairs according to the current universal unique identification code; and the RPC server calls data corresponding to the target server handle according to the searched target server handle, so that the handle in the RPC client corresponds to the handle of the RPC server, handle correspondence between differe
