The invention provides a network service message transmission method, a network service message transmission device, a terminal and a server, which relate to the technical field of communication. Thenetwork service message transmission method comprises the steps of: selecting a target compression strategy from preset compression strategies, wherein the target compression strategy and a current network bandwidth meet a preset correspondence relationship, and data transmission efficiency achieves a preset requirement under the current network bandwidth by adopting the target compression strategy; generating a compressed network service request message according to the target compression strategy; and transmitting the network service request message to a target server. The network service message transmission method and the network service message transmission device provided by the invention solve the problem that the whole service calling time consumption is prolonged since a fixedly compressed message is affected by unstable change of the network bandwidth in transmission when an existing network service message compression and transmission mode is adopted.
