Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
Referring to fig. 1, an embodiment of the present application provides a content sharing method, including the following steps:
step S1, the first user terminal obtains the current position information and uploads the position information to the background server;
step S2, inquiring a second user terminal which is at a preset distance from the position information from the background server;
step S3, when a function button on a page of a first user terminal receives a click operation of a user, triggering a sharing instruction, and calling a sharing code block corresponding to the sharing instruction from a preset code database;
step S4, verifying whether the shared code block is changed;
step S5, if not, acquiring the content to be shared based on the sharing code block; the content to be shared comprises a page address of the page or data content in a clipboard;
step S6, determining a target user terminal from the second user terminals;
step S7, sending the content to be shared to a background server, so as to be pushed to the page of the target user terminal through the background server.
In this embodiment, the method is applied to non-chat software for sharing page content, and third-party software is not required for content transfer.
Specifically, the software program is installed on a user terminal, and a user of the software program starts the working software at work (the app software can return to the background as long as a process is running). It should be noted that, in this embodiment, the user terminal that needs to perform page content sharing needs to start a corresponding location obtaining function, such as a GPS positioning function, a WIFI positioning function, and the like.
As stated in step S1, when the location obtaining function of the first user terminal is turned on, the first user terminal accesses the background through the socket, and then reports a piece of location information (the location information can be obtained from the navigator object or obtained by calling the location function of the mobile phone/computer) to the background server at preset time intervals (for example, 5S). The background server is deployed with a socket message processing code and provides functions of recording a position and inquiring nearby position sharable equipment, and other user terminals in a nearby preset range (for example, within 5 m) can be searched out according to the position information reported by the first user terminal. Therefore, the background server can push other user terminals which are searched to be within a preset range near the first user terminal to the first user terminal in a list form.
As described in the above step S2, the first user terminal may query the background server for the second user terminal located at the preset distance from the location information.
As stated in step S3, the software program on the first user terminal provides a sharing function, and when the user clicks a corresponding sharing function button on the page of the first user terminal, the sharing instruction is triggered, and a sharing code block corresponding to the sharing instruction is called from a preset code database, where the sharing code block is used to obtain the content to be shared on the current page.
As described in step S4, the process of security verification is integrated, that is, whether the program is corrupted by the trojan virus is verified, and when the program is corrupted by the trojan virus, the code file in the program is necessarily tampered with. The scheme is to verify whether the code in the program is tampered.
As described in step S5, if the shared code block is not changed, the page address of the current page or the data content in the clipboard is acquired. At this time, the page address of the page or the data content in the clipboard can be shared.
As described in step S6, during sharing, it is necessary to determine the target user terminal to be shared, and the target user terminal is selected from the second user terminals, so that the user can select the corresponding target user terminal as needed.
As described in step S7, the page address of the page or the data content in the clipboard is sent to a background server, and the content to be shared is pushed to the page of the target user terminal by forwarding through the background server.
And when the user of the second user terminal receives the shared content, the second user terminal can directly open and access the page address or directly view the data content in the clipboard, so that the whole sharing process is completed.
In an embodiment, the step S4 of verifying whether the shared code block is changed includes:
step S41, starting an analysis engine, and analyzing the shared code block into a shared code;
step S42, carrying out hash calculation on the shared code to obtain a corresponding code hash value;
step S43, judging whether the code hash value is the same as a preset hash value; the preset hash value is obtained by carrying out hash calculation in advance according to a preset shared code;
step S44, if the code blocks are the same, determining that the shared code block is not changed; and if not, judging that the shared code block is changed.
In this embodiment, in the prior art, characteristics of the trojan viruses are usually maintained in a database, and when checking and killing the trojan, matching is performed according to the characteristics of the trojan viruses, and whether a program includes a corresponding file is determined. In this embodiment, the corresponding shared code block is first obtained, the shared code block is analyzed into a shared code, hash calculation of the shared code is then performed, and if any character in the shared code is changed, the hash value of the code generated correspondingly will be changed. Therefore, a hash value obtained by performing hash calculation according to the initial shared code may be prestored in the database as a preset hash value, the calculated preset hash value is used as a judgment standard, and if the code hash value generated in the verification process is different from the preset hash value, the shared code is tampered, so that a security risk exists, and the shared code is not suitable to be shared continuously.
In an embodiment, the step S7 of sending the content to be shared to a background server includes:
step S7a, acquiring the identification information of the user and extracting a preset character conversion table; the character conversion table comprises corresponding conversion relations between identification information and characters;
step S7b, converting the identification information into corresponding characters according to the character conversion table;
step S7c, inserting the characters into the designated positions of the page addresses of the pages, and sending the page addresses into which the characters are inserted to the background server.
In this embodiment, when sharing the page address, the page address is not directly shared, but the page address is tampered by using the above method, so that the page address is changed to be unusable, and after the terminal where the shared user is located acquires the page address, the shared user can perform resolution in the same manner to acquire a correct page address.
In this embodiment, the content to be shared is text content in the clipboard;
the step S7 of sending the content to be shared to the background server includes:
step S701, acquiring the original position of the text content in the page;
step S702, judging whether the text content is continuous in the page;
step S703, if the content is discontinuous, using each discontinuous segment of the text content as a segment of target content;
step S704, sequencing the target contents in sequence according to the original positions of the target contents in the page;
step S705, calculating the characteristic value of each section of target content in sequence; the characteristic value comprises a corresponding hash value;
step S706, sequentially taking the characteristic value of the previous section of target content as the encryption password of the next section of target content to encrypt the next section of target content; the characteristic value of the last section of target content is used as the encryption password of the first section of target content;
and step S707, combining the target contents after the encryption processing, and sending the combined target contents and the feature value of the last target content to the background server.
In this embodiment, in order to enhance the security of the content to be shared in the sharing process, the text content is not directly shared but the original position of the text content in the page is obtained during sharing; judging whether the text content is continuous in the page or not; taking each discontinuous text content as a section of target content; sequencing the target contents in sequence according to the original position of each section of the target contents in the page; then calculating the characteristic value of each section of target content in sequence; the characteristic value comprises a corresponding hash value; and the hash value is used as an encryption password to encrypt the target content, and the encrypted target content is sent to the background server to be shared to other users. After the shared user terminal acquires the processed target content, the shared user terminal can perform analysis in the same manner to acquire corresponding text content.
In this embodiment, the content to be shared is text content in the clipboard; the step S7 of sending the content to be shared to the background server includes:
adding the shared content to a blank layer to generate a shared picture;
acquiring the data volume of the shared picture, and judging whether the data volume is larger than a threshold value;
if the number of the shared pictures is larger than the preset value, detecting a central point of the shared pictures, and taking the central point as a geometric center to form a rectangular frame;
cutting the frame of the rectangular frame to obtain a first image in the rectangular frame and a second image outside the rectangular frame;
and respectively sending the first image and the second image to the background server.
In this embodiment, the content to be shared is shared to the target user terminal in the form of a picture, and when the picture is uploaded, if the data size of the picture is too large, the uploading is easy to be unsuccessful, so that the clipping process needs to be performed on the picture. In this embodiment, a central point of the shared picture is detected, and a rectangular frame is formed by taking the central point as a geometric center; cutting the frame of the rectangular frame to obtain a first image in the rectangular frame and a second image outside the rectangular frame; the first image and the second image are respectively sent to the background server, and when the shared picture needs to be viewed subsequently, the first image and the second image only need to be spliced together.
