step S32, generating a two-dimensional code according to the network condition of the display system, wherein the two-dimensional code at least comprises a first connection address;
step S34, calling a display module to control a display screen to display the two-dimensional code through the display module so as to establish connection between the user equipment and the WEB service module;
and step S36, calling the WEB service module to call the first component in the display module to execute the first operation through the WEB service module in response to the first instruction from the user equipment.
In some embodiments, step S32 may include: detecting the network connection state of the display system; when the network connection state of the display system is network connection, the two-dimensional code is directly generated according to the first connection address, so that the user equipment can establish connection with the WEB service module through the Internet.
In some embodiments, the first connection address of the WEB service module 112 can be represented by an IP address and port information of the WEB service module 112, or can be represented by a Uniform Resource Locator (URL) of the WEB service module 112. In a specific application, the IP address, port information, URL, etc. of the WEB service module 112 may be configured when the WEB service module is created.
In step S32, a two-dimensional code including the IP address and the port information of the WEB service module 112 or a two-dimensional code including the URL of the WEB service module 112 may be generated, and the user equipment may obtain the IP address and the port information or the URL of the WEB service module 112 by scanning the two-dimensional code, and then send a connection request to the WEB service module 112 according to the IP address and the port information or the URL of the WEB service module 112 and establish a connection.
In some embodiments, step S32 may further include: when the network connection state of the display system is no network connection, the WIFI module 114 is started, and a two-dimensional code is generated according to the network connection address and the first connection address of the WIFI module 114, so that the user equipment can establish connection with the WEB service module through the WIFI hotspot provided by the display system. That is, in step S32, if the display system has no network connection, that is, under the condition that the display system cannot access the internet or other networks, the user equipment may obtain the first connection address and the WIFI network connection address of the display system at the same time by scanning the two-dimensional code by generating the two-dimensional code including the first connection address and the WIFI network connection address of the display system, so that the user equipment can establish network connection with the display system through the WIFI hotspot provided by the display system, and establish connection with the WEB service module 112 of the display system by means of the network connection.
In some embodiments, the first instruction refers to an instruction for content presented on the display screen, the first operation refers to an operation corresponding to the first instruction, and the first component is a component of the display module 111 that performs an operation indicated by the first instruction. For example, the first instruction in step S36 may include, but is not limited to, one or more of the following: a fast forward instruction, a fast backward instruction, a switching instruction, a playing stopping instruction, a pause instruction, a closing instruction and a starting instruction; the first component may include, but is not limited to, one or more of the components in the foregoing display module 111. The first operation may include, but is not limited to, one or more of: fast forward, fast backward, switch, play, stop play, pause, close, open. Of course, the first instruction and the first operation may also include other operations, such as a play speed setting, a definition setting, and the like, and the disclosure is not limited to the specific details of the first instruction and the first operation.
In some embodiments, step S36 may include: calling a WEB service module to execute the following processing through the WEB service module: and responding to a first instruction aiming at the first local file from the user equipment, calling a local query module to query and acquire the first local file in the display system, and calling a first component of the display module to execute a first operation on the first local file so as to control a corresponding display screen to display the content appointed by the user in a user-appointed mode. Therefore, the user equipment can directly call the local query module and the display module in the display system through the connection between the user equipment and the WEB service module to realize the arbitrary operation of any file stored in the display system.
It should be noted that the first local file is any file stored in the display system, and may be, but is not limited to, the content file in the storage module 116.
For example, the first instruction may include information of a first local file (e.g., a storage address, a file name, a file code, or information capable of uniquely identifying a file), the user device 200 sends an HTTP request to the host 110 of the display system, where the HTTP request carries the first instruction, after receiving the HTTP request, the WEB service module 112 in the host 110 of the display system parses the HTTP request to obtain a first instruction, and transmits the first instruction to the main control module 119, the main control module 119 invokes the local query module 118 to query the storage module 116 and obtain the first local file according to the information of the first local file in the first instruction, and invokes a first component (i.e., a component corresponding to the first instruction) in the display module 111 to perform a first operation indicated by the first instruction on the first local file according to the first instruction, so as to control the corresponding display screen 120 (where a serial number or other identification information of the display screen may be carried in the first instruction) to display a user-specified manner And displaying the local content which the user wants to see to the user in a user-specified mode on a display screen specified by the user in response to the user requirement.
In some embodiments, step S36 may include: calling a WEB service module to execute the following processing through the WEB service module: in response to a first instruction aiming at a first external file from user equipment, the WEB service module calls an external file acquisition module to acquire the first external file from an external server, and simultaneously calls a first component of a display module to execute a first operation on the first external file so as to control a corresponding display screen to display the content specified by the user in a mode specified by the user.
