In the embodiment corresponding to fig. 2, when a user triggers a trigger operation of a screenshot item in a suspended screenshot button, a terminal device performs screenshot on a display interface of a current terminal device to obtain a screenshot picture, and then the terminal device uploads the screenshot picture to a background server, so that the background server only stores the screenshot picture in the local of the background server and does not store the screenshot picture in a memory of the terminal device, and at this time, the screenshot picture cannot be found in the memory of the terminal device; when the terminal device detects that a user views the screenshot picture, the background server generates an HTTP address corresponding to the screenshot picture, the terminal device calls an interface of the background server through the HTPP address so that the user views the screenshot picture, and the storage path of the screenshot picture is changed in a mode that the screenshot picture is stored in the local background server and cannot be stored in a memory of the terminal device so as to prevent an attacker from leaking terminal information in a mode of tracing the screenshot picture in the local terminal.
In an embodiment, as shown in fig. 3, after step S50, that is, after the terminal device calls an interface of the background server through the first HTPP address to view the screenshot stored locally in the background server, the method specifically includes the following steps:
s60: if the terminal equipment detects the problem feedback operation of the user for the screenshot picture, acquiring a feedback problem input by the user and the screenshot picture corresponding to the feedback problem;
the problem feedback operation refers to an operation behavior that a user performs click screen capture feedback on the terminal equipment, and after the user performs the operation behavior of the click screen capture feedback on the terminal equipment, the terminal equipment forms a corresponding problem feedback instruction; specifically, if the terminal device detects a problem feedback operation of the user for the screenshot picture, the feedback problem input by the user and the screenshot picture corresponding to the feedback problem are obtained according to the problem feedback instruction.
S70: the terminal equipment sends the feedback problems and the corresponding screenshot pictures to the background server so that the background server sends the feedback problems and the corresponding screenshot pictures to a problem management system.
The feedback problem refers to the problem that a user needs to feed back to a processing person in the actual operation process, and includes feedback time, feedback content, feedback state and the like, for example, the feedback time is 2 months and 1 day 2020, the feedback content is the accuracy of checking a screenshot picture, and the feedback state may be a state to be fed back or a fed back state.
The background server is in butt joint with the problem management system through an interface, so that the background server sends the feedback problems and the corresponding screenshot pictures to the problem management system, and the problem management system forwards the feedback problems and the corresponding screenshot pictures to corresponding processing personnel.
In the embodiment corresponding to fig. 3, the background server may interface with the problem management system, the terminal device detects a problem feedback operation of the user for the screenshot picture, and sends the problem feedback operation to the background server, the background server sends the feedback problem and the corresponding screenshot picture to the problem management system, and directly sends the feedback problem and the corresponding screenshot picture to the corresponding technician, so that the problem that the service staff feeds back the scene description to the technician after manually inputting the scene description can be avoided, and improper verification is easily caused.
In an embodiment, as shown in fig. 4, after the background server generates the first HTTP address corresponding to the screenshot picture, the method specifically includes the following steps:
s80: the background server judges whether the current screenshot picture checking time length exceeds the effective time length of the first HTTP address, wherein the current screenshot picture checking time length is the time length between the time when the background server receives the checking request and the time when the user clicks on the first HTTP address, and the effective time length is the time length between the time when the background server receives the checking request and the latest checking time of the screenshot picture;
optionally, after the terminal device calls an interface of the background server through the first HTPP address, before the background server feeds back the corresponding first HTTP address to the terminal device, the background server determines whether a current screenshot viewing duration exceeds an effective duration of the first HTTP address.
The effective duration of the first HTTP address refers to an effective limit duration of the HTTP address, that is, a duration that the HTTP address is available for a user to view effectively, that is, once the effective duration of the HTTP address expires, the HTTP address will be invalid, and the user cannot view the screenshot picture through the HTTP address, for example, the effective duration may be 30 minutes, 60 minutes, 1 day, and the like.
The effective duration of the HTTP address is as follows: the duration from the time when the background server receives the viewing request to the time when the screen capture picture is viewed at the latest is finished, for example, the time when the background server receives the viewing request is 12: 00, the latest viewing time of the screen capture picture is finished at 12:30, and the effective time length of the HTTP address is 30 minutes.
S90: and if the viewing time of the current screenshot picture exceeds the effective time, the background server sends an instruction to prohibit the terminal equipment from calling an interface of the background server through the first HTPP address.
Wherein the viewing time length of the current screenshot picture is as follows: the duration from the time when the background server receives the viewing request to the time when the user clicks on the first HTTP address is completed, for example, the time when the background server receives the viewing request is 12: 00, the time when the user clicks the first HTTP address can be 12:20 or 12:32, and the viewing time of the current screenshot is 20 minutes or 32 minutes.
If the current screenshot picture viewing duration is 20 minutes and the effective duration of the HTTP address is 30 minutes, the current screenshot picture viewing duration does not exceed the effective duration of the HTTP address, and at the moment, the time for the user to view the screenshot picture is within the effective duration of 30 minutes, and the user can view the screenshot picture through the HTTP address; if the current screenshot picture viewing time is 32 minutes and the effective time of the HTTP address is 30 minutes, the current screenshot picture viewing time exceeds the effective time of the HTTP address, at the moment, the time for the user to view the screenshot picture exceeds the effective time of 30 minutes, at the moment, the user clicks to enter the HTTP address, but the HTTP address is in a failure state, the background server sends an instruction to prohibit the terminal equipment from calling an interface of the background server through the HTPP address, and the user cannot view the screenshot picture; that is, after a certain time, the permission of the user to view the screenshot picture through the HTPP address is invalid, so that the safety of the server and the data thereof is improved.
In the embodiment corresponding to fig. 4, the validity duration of the screenshot picture viewing is defined by the effective duration of the HTTP address, and if the effective duration exceeds the preset screenshot picture viewing duration, the background server sends an instruction to prohibit the terminal device from calling a background server interface through the HTPP address, so as to prevent viewing of the screenshot picture stored locally in the background server, and further prevent the risk of information leakage.
In an embodiment, as shown in fig. 5, after step S50, that is, after the terminal device calls the interface of the background server through the first HTPP address, the method specifically includes the following steps:
s100: if the terminal device detects that the user proposes a re-viewing operation for the screenshot picture, the terminal device sends a re-viewing request of the screenshot picture to the background server so that the background server generates a second HTTP address corresponding to the screenshot picture and feeds the corresponding second HTTP address back to the terminal device;
after the background server sends an instruction to prohibit the terminal device from calling an interface of the background server through the first HTPP address, if the user needs to check the screen capture picture again, the user proposes a second check operation for the screen capture picture; if the terminal device detects that the user proposes a re-viewing operation for the screenshot picture, the terminal device sends a re-viewing request for the screenshot picture to the background server, and the background server generates a second HTTP address corresponding to the screenshot picture. Understandably, the step of the background server generating the first HTTP address corresponding to the screenshot picture may refer to step S40, which is not described herein in detail.
S110: and the terminal equipment calls an interface of the background server through the second HTPP address so as to view the screenshot picture stored locally in the background server.
The background server feeds the second HTTP address back to the terminal equipment, and the terminal equipment calls an interface of the background server through the second HTPP address so that a user can view the screenshot picture stored locally in the background server.
In the embodiment corresponding to fig. 5, after the background server sends an instruction to prohibit the terminal device from calling the interface of the background server through the first HTPP address, the user may further propose an operation of viewing the screenshot picture again, when it is detected that the user proposes the operation of viewing the screenshot picture again, the background server generates a second HTTP address corresponding to the screenshot picture, and the terminal device calls the interface of the background server through the second HTPP address to view the screenshot picture stored locally in the background server.
In an embodiment, as shown in fig. 6, after the step S20, that is, after the screen capture is performed on the display interface of the current terminal device to obtain the screen capture picture, the method specifically includes the following steps:
s120: the terminal equipment stores the screen capture picture in an operating memory of a target application APP;
s130: and if the terminal equipment receives a quitting operation of quitting the target application APP triggered by a user, triggering the running memory of the target application APP to automatically release so as to enable the screenshot picture stored in the running memory of the target application APP to disappear.
The background server sends the screenshot picture to the running memory of the target application APP for storage, so that the screenshot picture is displayed in the target application APP, and if the user does not have a quitting operation of quitting the target application APP triggered all the time, the user can check the screenshot picture in the target application APP all the time; and if the quitting operation of the target application APP triggered by the user is quitted, triggering the running memory of the target application APP to automatically release, emptying the screen capture picture stored in the running memory of the target application APP, and at the moment, eliminating the screen capture picture stored in the running memory of the target application APP.
In the embodiment corresponding to fig. 6, the screenshot picture may also be stored in the running memory of the target application APP, so that the screenshot picture is displayed in the target application APP, and if the target application APP is triggered to exit the operation, the screenshot picture disappears and cannot be stored in the running memory of the target application APP, so as to prevent information leakage.
In an embodiment, the floating screen capture key further includes a home page return button, and when the terminal device detects that the user triggers the home page return button, the terminal device returns to the home page of the target application APP.
When the number of pages opened by the target application APP is large, the home page can be quickly returned to the home page of the target application APP through a home page returning button triggered by a user.
Optionally, the floating screen capture key further includes a proxy function button, and when the user needs to handle the proxy service, the user can also enter the page with the service function quickly through the proxy function button triggered by the user, for example, if the service function is the service proxy function, the user triggers the service proxy function button, and then the user enters the page proxy page with the corresponding service proxy function.
In this embodiment, when the pages opened by the target application APP are many, the home page returning button triggered by the user can be used for quickly returning to the home page of the target application APP, so that the working efficiency is improved.
