Referring to fig. 1, an HTTP protocol-based remote control method according to an embodiment of the present application includes:
s1: the method comprises the steps that a user terminal scans a bar code displayed by a controlled terminal, and a control page corresponding to the bar code is entered through a preset browser;
s2: the user terminal receives control operation triggered by a user through the control page and generates a control instruction corresponding to the control operation;
s3: the user terminal sends the control instruction to the server through the HTTP protocol;
s4: the server receives the control instruction and sends the control instruction to the controlled terminal through an HTTP protocol;
S5: the controlled terminal receives the control instruction through a preset control module;
s6: the controlled terminal converts the control instruction into a corresponding control handle through the control module;
s7: and the controlled terminal controls the control object corresponding to the control instruction through the control handle.
As described in steps S1 to S7, the present embodiment relates to a remote control method based on the HTTP protocol, and the main body for executing the remote control method based on the HTTP protocol includes three types, namely, a user terminal, a server and a controlled terminal. Specifically, firstly, a user terminal scans a bar code displayed by a controlled terminal, and enters a control page corresponding to the bar code through a preset browser. The user terminal is an intelligent terminal held and used by a user, for example, a smart phone, and has a function of bar code scanning and analysis, and a preset browser capable of performing data transmission by using an HTTP protocol is installed inside the user terminal. The bar code includes identification information and address information corresponding to the controlled terminal, and the type of the bar code is not particularly limited and may include a one-dimensional bar code, a two-dimensional bar code (two-dimensional code), and the like. In addition, the control page is a special webpage corresponding to the controlled terminal, and all touch operations or control operations performed by the user on the control page are directly applied to the control object of the controlled terminal, so that the effect of remotely controlling the controlled terminal through the user terminal is achieved. And then the user terminal receives the control operation triggered by the user through the control page and generates a control instruction corresponding to the control operation. The control page includes control buttons corresponding to various control functions of the controlled terminal, and a user can touch any one or more control buttons according to the actual requirement of the user to control the functions of the controlled terminal. And then the user terminal sends the control instruction to the server through the HTTP protocol. After receiving the control instruction, the server side sends the control instruction to the controlled terminal through the HTTP protocol. Among other things, the HTTP (HyperTextTransfer Protocol ) protocol is an application layer protocol for distributed, collaborative, and hypermedia information systems. The HTTP service, that is, the HTTP protocol, is used to transfer control instructions between terminals, which is generally applicable to web pages or applications, without additional technical development. And finally, the controlled terminal controls the control object corresponding to the control instruction according to the received control instruction. The controlled terminal is a terminal for being controlled or controlled by a user, for example, the controlled terminal can be a large-screen television or a display machine, or a PC (personal computer) and the like; the control object includes a web page or an application. Specifically, the control implementation process of the controlled terminal for controlling the control object corresponding to the control instruction according to the received control instruction specifically includes: the controlled terminal receives the control instruction through a preset control module. The control module is integrated into the controlled terminal through a code layer, the control module is mainly used for receiving a control instruction forwarded by the server to realize information interaction between the controlled terminal and the server and between the controlled terminal and the user terminal, and the control module can control the controlled terminal to execute corresponding control operation according to the control instruction. And then the controlled terminal converts the control instruction into a corresponding control handle through the control module. The control handle is data for identifying the control parameters of the controlled terminal, and the control parameters of the controlled terminal can be controlled by calling the control handle, so that the aim that the control module can correspondingly control the controlled terminal according to the received control instruction is fulfilled. In addition, the control command can be analyzed to obtain a corresponding control parameter, and a control handle corresponding to the control command can be generated according to the control parameter. In addition, the control handle can be stored in a blockchain of a blockchain system, and the generated control handle is stored and managed by using the blockchain, so that the safety and the non-falsifiability of the control handle can be effectively ensured. When the control handle is obtained, the controlled terminal controls the control object corresponding to the control instruction through the control handle, and further the appointed content corresponding to the control instruction can be displayed in the control object. The controlled terminal can analyze and process the control instruction to obtain a control object corresponding to the control instruction. In addition, when the control module calls the control handle, the control parameters in the control instruction are converted into the control parameters in the control handle. For example, if the above control instruction is a pause instruction, among the control instructions, the control parameter corresponding to the pause instruction is pause. However, in the control handle, the control parameter representing the pause instruction is a specific character string different from the pause, and the control module invokes the specific character string corresponding to the pause, and determines the control handle having the mapping relation with the specific character string according to the specific character string, so that the pause control of the control object in the controlled terminal can be realized according to the obtained control handle. In addition, in order to avoid the confusion of the controlled terminal, one controlled terminal only receives remote control of one user terminal at a time, when the condition that the bar code displayed by one appointed controlled terminal is scanned by a plurality of user terminals occurs, the server side only responds to a remote control request initiated by the first appointed user terminal with the fastest scanning time according to the time sequence of scanning the bar code of each user terminal, namely, only successfully loads a control page corresponding to the bar code in a browser of the appointed user terminal, and sends connection failure information to other user terminals except the appointed user terminal so as to remind other users that the appointed controlled terminal is connected with the appointed user terminal currently and cannot be connected with other user terminals any more. The content of the connection failure information is not particularly limited, and may be, for example: connection failure, please try again later or attempt to connect to other machines. The embodiment can be applied to the field of smart cities, thereby promoting the construction of the smart cities. Through the embodiment, a user can conveniently and rapidly realize remote control of the controlled terminal corresponding to the bar code through the browser by only scanning the bar code displayed by the controlled terminal through the user terminal, and the problems of high experience cost and high management difficulty when the user interacts with a customer in a commercial environment can be effectively solved. In addition, through the controlled terminal with the large screen system, products or services of enterprises are displayed through the controlled terminal, when on-site customer users have the requirement of experiencing the products, namely the requirement of operating the application or the webpage displayed on the terminal equipment, the user terminal of the user terminal can instantly scan the bar code displayed by the controlled terminal to remotely control the controlled terminal, no additional keyboard or other interactive equipment is needed, no additional application is needed for the user terminal, the control experience can be realized only through the browser in the user terminal, no direct relation with the mobile phone system and configuration exists, and the compatibility is better. From the perspective of a user, only the user terminal of the user is needed to be used when the remote control of the controlled terminal is performed, and no additional control application or data line connection is needed to be installed, so that the remote control system more accords with the control habit of the user, and has higher efficiency and better experience. And when the remote control is performed, the equipment purchasing cost and the management cost are greatly saved as no additional interactive equipment support is needed.
Further, in an embodiment of the present application, the step S1 of the user terminal scanning the bar code displayed by the controlled terminal and entering the control page corresponding to the bar code through the preset browser includes:
s100: the user terminal judges whether the bar code scanning operation triggered by the user is detected;
s101: if judging that the bar code scanning operation triggered by the user is detected, the user terminal executes a scanning instruction corresponding to the bar code scanning operation and judges whether the bar code displayed by the controlled terminal is scanned or not;
s102: if the user terminal judges that the bar code displayed by the controlled terminal is scanned, the bar code is analyzed to obtain corresponding address information;
s103: and the user terminal enters the control page corresponding to the address information through the browser according to the address information.
As described in the steps S100 to S103, the step of the user terminal scanning the bar code displayed by the controlled terminal and entering the control page corresponding to the bar code through the preset browser may specifically include: the user terminal first determines whether a user-triggered bar code scanning operation is detected. The triggering mode of the barcode scanning operation is not particularly limited, and for example, a mode of pressing a physical button or a virtual button, a mode of inputting voice, and the like can be adopted. And if the user terminal judges that the bar code scanning operation triggered by the user is detected, executing a scanning instruction corresponding to the bar code scanning operation, and judging whether the bar code displayed by the controlled terminal is scanned. The bar code displayed by the controlled terminal is automatically generated after the control module is integrated in the controlled terminal, and the bar code comprises the identity information of the server end to the controlled terminal and the address information corresponding to the control object in the controlled terminal. And if the user terminal judges that the bar code displayed by the controlled terminal is scanned, the bar code is analyzed to obtain the corresponding address information. And finally, when the address information is obtained, the user terminal enters the control page corresponding to the address information through the browser according to the address information, so that a subsequent user can perform corresponding touch operation on the control page to realize remote control on the controlled terminal, the intelligence and the simplicity of the remote control of the terminal are effectively improved, and the use experience of the user is improved.
Further, in an embodiment of the present application, before step S5 of receiving, by the controlled terminal, the control instruction through a preset control module, the method includes:
s500: the controlled terminal receives the input control code;
s501: the controlled terminal generates a control module corresponding to the control code according to the control code;
s502: and the controlled terminal integrates the control module internally.
As described in the above steps S500 to S502, before the step of receiving the control instruction by the controlled terminal through the preset control module, the method further includes a generating process for generating the control module. Specifically, the controlled terminal first receives an input control code. The control codes can be written and input into the controlled terminal by a developer according to actual service requirements. And then the controlled terminal generates a corresponding control module according to the control code. The control module can be generated by acquiring the control function corresponding to the user demand through the control code and writing the control interface corresponding to the control function corresponding to the user demand into a preset module template. And finally, when the control module is generated, the controlled terminal integrates the control module internally. The control module is integrated into the controlled terminal through a code layer, the main function of the control module is to transmit control instructions sent by a user through the user terminal to the controlled terminal, the control interfaces of different controlled terminals are specific, the control information can be transmitted only through the integrated control module, and otherwise, interaction of control objects in the controlled terminal cannot be controlled. According to the embodiment, the corresponding control module is generated according to the input control code, and the control module is integrated in the controlled terminal, so that the control instruction forwarded by the server is converted into the corresponding control handle through the control module, the control object corresponding to the control command in the controlled terminal is controlled through the control handle, the appointed content corresponding to the control instruction is displayed in the control object, and the user can send the control instruction through the user terminal to complete remote control of the controlled terminal, so that the intelligence and simplicity of remote control of the terminal are effectively improved.
Further, in an embodiment of the present application, step S6 of converting, by the controlled terminal, the control instruction into a corresponding control handle through the control module includes:
s600: the controlled terminal obtains control parameters corresponding to the control instructions through the control module;
s601: the controlled terminal acquires character string information corresponding to the control parameters;
s602: and the controlled terminal converts the control instruction into the control handle according to the character string information.
As described in steps S600 to S602, the step of converting, by the control module, the control instruction into a corresponding control handle may specifically include: firstly, the controlled terminal obtains the control parameters corresponding to the control instructions through the control module. The control instruction is analyzed and processed, and control parameters corresponding to the control instruction are extracted. For example, if the control instruction is a pause instruction, the control parameter corresponding to the pause instruction may be extracted as pause after analysis. And then the controlled terminal acquires the character string information corresponding to the control parameters. When the specific parameter content corresponding to the control parameter corresponding to the control instruction is known, the character string information having a mapping relation with the specific parameter content can be extracted according to the specific parameter content. And finally, the controlled terminal converts the control instruction into the control handle according to the character string information, so that the controlled terminal can control a control object corresponding to the control instruction in the controlled terminal through the control handle, and display specified content corresponding to the control instruction in the control object, thereby intelligently and simply using the user terminal to realize remote control of the controlled terminal corresponding to the bar code. When the character string information corresponding to the control parameter in the control instruction is obtained, the control handle with the mapping relation with the character string information can be determined according to the character string information.
In an embodiment of the present application, after the step S500 of receiving the input control code by the controlled terminal, the method includes:
s503: and the controlled terminal stores the control code to a blockchain of the blockchain system.
After the controlled terminal receives the input control code, the controlled terminal may also perform secure storage processing on the received control code based on the blockchain to implement secure storage of the control code, as described in step S503. Specifically, after the step of receiving the input control code by the controlled terminal, the method may further include: and the controlled terminal stores the control codes to a block chain of the block chain system. The embodiment effectively ensures the security and the non-falsifiability of the received control codes by using the blockchain to store and manage the received control codes.
Further, in an embodiment of the present application, after step S5 of receiving, by the controlled terminal, the control instruction through a preset control module, the method includes:
s510: and the controlled terminal conceals the currently displayed bar code.
As described in step S510, after receiving the control instruction through the preset control module, the controlled terminal determines that the control instruction sent by the server is received, and may further include a hiding process for hiding the currently displayed barcode. Specifically, after the step of receiving the control instruction by the controlled terminal through the preset control module, the step of hiding the currently displayed bar code is included. The bar code comprises identity information and address information corresponding to the controlled terminal, and the bar code is displayed in a display interface of the controlled terminal after being generated so as to be scanned and connected by a user. When receiving a control instruction sent by a server through a preset control module, the controlled terminal in the embodiment indicates that a user terminal which establishes a control connection relationship with the controlled terminal exists currently, and then the controlled terminal can intelligently hide the currently displayed bar code in the display interface, so that other users are prevented from influencing the control operation of the current user terminal by scanning the bar code, and the disordered request of the remote control process caused by the fact that a plurality of users scan the bar code of the same controlled terminal is avoided, and the smoothness of the remote control operation of the user terminal on the controlled terminal is effectively ensured.
Further, after the controlled terminal controls the control object corresponding to the control instruction through the control handle, if it is determined that the control connection relationship between the user terminal and the controlled terminal is released, the controlled terminal intelligently restores the original state, and the display state of the bar code is displayed in the display interface. Specifically, after the step of the controlled terminal controlling the control object corresponding to the control instruction through the control handle, the method includes: and judging whether a new control instruction sent by the server is received in a preset time period. The content of the new control command may be the same as or different from that of the control command, but the appearance time of the new control command is after the control command. In addition, the above-mentioned preset period of time is not particularly limited, and may be set according to actual conditions, for example, may be set to 3 minutes. If the fact that the new control instruction sent by the server side is not received within the preset time period is judged, the controlled terminal judges that the user terminal finishes the remote control operation on the controlled terminal, and cancels the display of the specified content corresponding to the control object, and the bar code is displayed in the display interface again. According to the method and the device, when the new control instruction sent by the server is not received in the preset time period, the user terminal can be intelligently judged to be in control connection relation with the controlled terminal, and then the bar code can be displayed in the display interface again later, so that other users can conveniently and rapidly realize new remote control of the controlled terminal by scanning the bar code, and continuous fluency of remote control of the controlled terminal is effectively guaranteed.
