Background
Content sharing refers to a process in which user a perceives a need to inform user B of understanding or processing after seeing an arbitrary page (H5 page)/content (a piece of content in H5). The non-communication software refers to non-chat type working software, such as an operating system.
The main forms of information sharing of the non-chat software at present are as follows: and the user A shares a plurality of pages to the user B through a WeChat or a QQ and other third-party platforms, and the user B opens a sharing link to arouse the software to read the shared content. This form has the following disadvantages:
1. the internal information is transferred through the third party software, so that the risk of information leakage exists, and the operation is inconvenient (the working software is basically always in an open state, the information sharing also needs to pass through the third party software, and the operation steps are added).
2. If the user B does not open the message reminding function of the communication tool such as WeChat, the user A also needs to inform the user B to check or process the content in a telephone or information form, and the user A cannot process the content in time when encountering important information.
3. If the user A pushes the information to the user B, the working software of the user B is pc on line, and the H5 page cannot directly call the pc-end working software in tools such as pc-end WeChat and the like.
4. While the user A and the user B belong to the same company, when the user A and the user B face to face but are friends of non-social tools, the user A and the user B cannot push the content directly face to face, and the user A and the user B need to add social friends and then operate the user A and the user B.
In view of the above-mentioned shortcomings, a scheme is needed for effectively sharing information in an operating system which cannot directly communicate information without relying on third party software.

Detailed Description
The present application will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present application more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the application.
Referring to fig. 1, in an embodiment of the present application, a content sharing method is provided, including the following steps:
step S1, a first user terminal acquires current position information and uploads the position information to a 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, triggering a sharing instruction when a function button on a page of a first user terminal receives a clicking operation of a user, 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 or not;
step S5, if no change occurs, obtaining the content to be shared based on the shared 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;
and step S7, the content to be shared is sent 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 the non-chat software to share the page content, and no third party software is required to transfer the content.
Specifically, the software program is installed on the user terminal, and a user of the software program starts the working software when working (app end software can be backed up to the background, so long as a process is running). It should be noted that, in this embodiment, the user terminal that needs to share the page content needs to initiate a corresponding location acquiring function, such as a GPS positioning function, a WIFI positioning function, and so on.
As described in step S1, when the position obtaining function of the first user terminal is turned on, the first user terminal is connected to the background through a socket, and then a piece of position information (the position information can be obtained from a navigator object or can be obtained by calling the positioning function of the mobile phone/computer) is reported to the background server at intervals of a preset time (for example, 5S). The background server is provided with a socket message processing code, and provides functions of position record and inquiry of nearby position sharable equipment, and the background server can search other user terminals within a nearby preset range (for example, within 5 m) 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 step S2, the first ue may query the background server for a second ue that is at a preset distance from the location information.
As described 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, a 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 of the current page.
As described in step S4 above, the security verification process is integrated, i.e. it is verified whether the underlying program is corroded by the Trojan virus, and the code file in the program must be tampered with when the Trojan virus corrodes the program. This scheme is to verify whether the code in the program has been tampered with.
If the shared code block is not changed, the page address of the current page or the data content in the clipboard is obtained as described in step S5. At this time, the page address of the page or the data content in the clipboard can be shared.
As described in the above step S6, during sharing, a target user terminal to be shared needs to be determined, and the target user terminal is selected from the second user terminals, so that the user can select a corresponding target user terminal according to the need.
And (3) sending the page address of the page or the data content in the clipboard to a background server, forwarding the data content via a background service, and pushing the content to be shared to the page of the target user terminal.
When the user of the second user terminal receives the shared content, the user can directly open and access the page address or directly look up the data content in the clipboard, thereby completing the whole sharing process.
In one embodiment, the step S4 of verifying whether the shared code block is changed includes:
step S41, starting an analysis engine to analyze the shared code block into a shared code;
step S42, carrying out hash calculation on the shared codes to obtain corresponding code hash values;
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 sharing code;
step S44, if the shared code blocks are the same, judging that the shared code blocks are not changed; and if the shared code blocks are different, judging that the shared code blocks are changed.
In this embodiment, in the prior art, the characteristics of the Trojan virus are usually maintained in the database, when the Trojan is checked and killed, matching is performed according to the characteristics of the Trojan virus, and whether the program contains the corresponding file is determined. In this embodiment, the corresponding shared code block is first obtained, the shared code block is resolved into the shared code, and then the hash calculation of the shared code is performed, and if any character in the shared code is changed, the corresponding generated code hash value will be changed. Therefore, a hash value obtained by performing hash calculation according to an initial shared code can be pre-stored in the database and used as a preset hash value, the calculated preset hash value is used as a judgment standard, if the code hash value generated in the verification process is different from the preset hash value, the shared code is tampered, and the security risk exists, and at this time, the sharing is not suitable to be continued.
In an embodiment, the content to be shared is a page address of the page, and the step S7 of sending the content to be shared to the background server includes:
step S7a, obtaining the identification information of the user, and extracting a preset character conversion table; the character conversion table comprises the corresponding conversion relation between the identification information and the characters;
step S7b, converting the identification information into corresponding characters according to the character conversion table;
and S7c, inserting the characters into the appointed position of the page address of the page, and sending the page address after inserting the characters to the background server.
In this embodiment, when sharing the page address, the page address is not directly shared, but tampered in the manner described above, so that the page address is changed to be unusable, and after the shared user terminal obtains the page address, the shared user terminal may analyze in the same manner to obtain the 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 an original position of the text content in the page;
step S702, judging whether the text content is continuous in the page;
step S703, if discontinuous, using each discontinuous text content in the text content as a target content;
step S704, sequentially sequencing the target contents according to the original positions of each section of the target contents in the page;
step S705, calculating the characteristic value of each piece of target content in turn; the characteristic value comprises a corresponding hash value;
step S706, sequentially taking the characteristic value of the previous target content as the encryption password of the next target content to encrypt the next target content; the characteristic value of the last section of target content is used as an encryption password of the first section of target content;
and step S707, after the target contents are combined after the encryption processing, the target contents and the characteristic value of the last target content are sent 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 during sharing, but the original position of the text content in the page is obtained; judging whether the text content is continuous in the page or not; taking each discontinuous text content as a target content; sequentially sequencing the target contents according to the original positions of each section of the target contents in the page; then calculating the characteristic value of each section of target content in turn; 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 a background server for sharing to other users. After the terminal of the shared user obtains the processed target content, the terminal can analyze the processed target content in the same mode to obtain the 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 sharing picture, and judging whether the data volume is larger than a threshold value;
if the picture is larger than the first preset value, detecting a center point of the shared picture, and taking the center 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 if the amount of the picture data is too large during uploading the picture, the uploading is not successful easily, so that the picture needs to be cut. In this embodiment, a center point of the shared picture is detected, and a rectangular frame is made with the center 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 then when the sharing picture is required to be checked, the first image and the second image are only required to be spliced, and as the shapes of the image elements in the first image and the second image are just matched, the image confusion can be avoided during the splicing.
