Technical Field The present application relates to the field of communications technologies, and in particular, to a method, an apparatus, a device, and a system for energy-saving interaction of an access point. Background Wireless local area networks (wireless local area network, WLAN) are becoming more and more popular, and WLAN includes Stations (STAs) and Access Points (APs), and energy saving is focused on energy saving of the stations at present, so as to prolong the standby time of the stations. Disclosure of Invention The application provides a method for energy-saving interaction of an access point, which can provide an interaction scheme of a master access point and a slave access point when the access point performs energy-saving control. The technical scheme adopted is as follows: In a first aspect, the application provides a method for energy-saving interaction of access points, which is applied to a first access point in an optical fiber-to-room (fiber to the room, FTTR) network, wherein the first access point is connected with at least one access point in the FTTR network, the method comprises the steps of receiving a first energy-saving request sent by a second access point in the at least one access point, wherein the first energy-saving request is used for indicating the second access point to apply for entering an energy-saving mode, and sending an energy-saving indication message to the second access point, wherein the energy-saving indication message is used for indicating the second access point to enter or exit the energy-saving mode. In the scheme shown in the application, the second access point actively initiates energy-saving negotiation with the first access point in FTTR network, so that the first access point knows that the second access point can enter an energy-saving mode, and the first access point can assign energy-saving operation, namely energy-saving state, to the second access point later, and the energy-saving operation is equivalent to the energy-saving state, so that the overall power consumption of the access point in FTTR network is reduced. In an alternative mode, the energy saving indication message is used for indicating the second access point to enter the energy saving mode, and after the energy saving indication message is sent to the second access point, the method further comprises receiving a second energy saving request sent by the second access point after exiting the energy saving mode, wherein the second energy saving request is used for indicating the second access point to exit the energy saving mode. In an alternative way, the second energy saving request comprises an indication identifier for indicating an exit energy saving and an indication identifier for indicating an emergency exit energy saving. In this way, the first access point can know the reason why the second access point exits the energy saving state, whether to periodically exit or exit after an emergency event occurs, so as to better globally decide the energy saving mechanism. In an alternative mode, the energy saving indication message is used for indicating the second access point to enter the energy saving mode, and after the energy saving indication message is sent to the second access point, the method further comprises sending an energy saving exit request to the second access point, wherein the energy saving exit request is used for indicating the second access point to exit the energy saving mode. To do some of the necessary processing. For example, if the first access point detects that a station roams to a second access point or a new access station, the second access point needs to be awakened. In an alternative way, the energy saving exit request includes an indication identifier for indicating exiting the energy saving mode and an indication identifier for indicating exiting the energy saving mode in an emergency. In this way, the second access point may decide the operation to be performed next according to whether an indication flag for indicating an emergency exit from the power saving is included. In an alternative mode, the energy saving indication message is used for indicating the second access point to enter the energy saving mode, and after the energy saving indication message is sent to the second access point, the method further comprises the step of sending an energy saving control message to the second access point, wherein the energy saving control message is used for indicating the second access point to execute target energy saving operation. In this way, the first access point may ass
