A cache data request method, comprising: detecting, by a data request device, a first request message specific to a target data server, wherein the data request device determines that the first request message is specific to the target data server by detecting that a target address of the first request message is an IP address and/or a port number of the target data server; determining, by the data request device based on a pre-received local cache device list sent by a base station, a target local cache device used to cache service data of the target data server; and establishing, by the data request device, a network connection to the target local cache device, and sending a service data request specific to the target data server to the target local cache device by using the network connection, wherein the local cache device list comprises an identifier of at least one local cache device, wherein the local cache device is an independent cache device connected to the base station, or is a part of the base station; the method being characterized in that the determining, by the data request device based on a pre-obtained local cache device list, a target local cache device used to cache service data of the target data server comprises: determining, by the data request device, whether a first identifier consistent with an identifier of a local cache device in the local cache device list exists in a pre-obtained cache content authorization list, wherein the cache content authorization list comprises an identifier of at least one local cache device that is authorized by the target data server to perform caching; and if the first identifier exists in the cache content authorization list, determining, by the data request device, that a local cache device corresponding to the first identifier is the target local cache device, and wherein before the determining, by the data request device, whether a first identifier consistent with an identifier of at least one local cache device in the local cache device list exists in a pre-obtained cache content authorization list, the method further comprises: receiving, by the data request device, the cache content authorization list sent by the target data server. detecting, by a data request device, a first request message specific to a target data server, wherein the data request device determines that the first request message is specific to the target data server by detecting that a target address of the first request message is an IP address and/or a port number of the target data server; determining, by the data request device based on a pre-received local cache device list sent by a base station, a target local cache device used to cache service data of the target data server; and establishing, by the data request device, a network connection to the target local cache device, and sending a service data request specific to the target data server to the target local cache device by using the network connection, wherein the local cache device list comprises an identifier of at least one local cache device, wherein the local cache device is an independent cache device connected to the base station, or is a part of the base station; the method being characterized in that the determining, by the data request device based on a pre-obtained local cache device list, a target local cache device used to cache service data of the target data server comprises: determining, by the data request device, whether a first identifier consistent with an identifier of a local cache device in the local cache device list exists in a pre-obtained cache content authorization list, wherein the cache content authorization list comprises an identifier of at least one local cache device that is authorized by the target data server to perform caching; and if the first identifier exists in the cache content authorization list, determining, by the data request device, that a local cache device corresponding to the first identifier is the target local cache device, and wherein determining, by the data request device, whether a first identifier consistent with an identifier of a local cache device in the local cache device list exists in a pre-obtained cache content authorization list, wherein the cache content authorization list comprises an identifier of at least one local cache device that is authorized by the target data server to perform caching; and if the first identifier exists in the cache content authorization list, determining, by the data request device, that a local cache device corresponding to the first identifier is the target local cache device, and wherein before the determining, by the data request device, whether a first identifier consistent with an identifier of at least one local cache device in the local cache device list exists in a pre-obtained cache content authorization list, the method further comprises: receiving, by the data request device, the cache content authorization list sent by the target data server.
