[0025] Hereinafter, embodiments of the disclosure will be described with reference to the accompanying drawings. However, it is to be understood that these descriptions are merely exemplary and are not intended to limit the scope of the disclosure. In the following detailed description, numerous specific details are set forth in order to provide a thorough understanding of the embodiments of the disclosure. However, it will be apparent to one skilled in the art that one or more embodiments can be practiced without these specific details. In other instances, well-known structures and techniques have been omitted in order to avoid obscuring the concepts of the disclosure.

[0026] The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the disclosure. As used herein, the terms "comprises", "comprising", and the like are intended to indicate the presence of stated features, steps, operations, and / or components, but do not preclude the presence or addition of one or more other features, steps, operations, or components.

[0027] All terms used herein, including technical and scientific terms, have the meanings commonly understood by one of ordinary skill in the art, unless otherwise defined. It should be noted that the terms used herein should be interpreted as having meanings consistent with the context of the specification, and should not be interpreted in an idealized or overly formal manner.

[0028] In the case of using expressions similar to "at least one of A, B, and C, etc.", it should generally be interpreted to include any one of A, B, or C, a combination of at least two of A, B, and C, or a combination of A, B, and C, etc., unless otherwise specified.

[0029] In embodiments of the disclosure, the collection, updating, analysis, processing, use, transmission, provision, disclosure, storage, etc. of data involved (for example, including but not limited to user personal information) comply with relevant laws and regulations, are used for legal purposes, and do not violate public order and good customs. In particular, necessary measures are taken to prevent illegal access to user personal information data and maintain information security.

[0030] In embodiments of the disclosure, the authorization or consent of the user is obtained before the user's personal information is acquired or collected.

[0031] In the related art, when data indicating that one or more layers are in a selected state is recorded in each client, the layers displayed by each client can be inconsistent, which gives the user the illusion that the system has a bug (error), and causes the user to need to perform a selection operation on the layers again each time the client is changed, thereby affecting the user's office efficiency.

[0032] In other technologies, when data indicating that one or more layers are in a selected state is recorded in the server, the operations of different clients can be mutually covered. For example, when a user operates to check a display layer on a PC (Personal Computer), the user updates the data according to the operation of the PC, and other clients are not aware of this. In the case where the other clients do not refresh the calendar list and perform a re-selection operation on the layers, the operation of the PC is covered. When the PC re-enters the view, the user finds that the display layer set previously is modified. This causes the user to have difficulty in understanding how to operate to make the display layers on different clients consistent, thereby affecting the user experience and office efficiency.

[0033] Embodiments of the present disclosure provide a layer rendering method and device, electronic equipment, storage medium and program product, and relate to the field of computer vision. The method comprises: in response to receiving a layer operation request for an existing layer in a current view based on a first communication connection, analyzing the layer operation request to determine a request layer for which the request operation is performed, wherein the current view represents a view in a current client, and the current view includes a displayed layer; calculating a target rendering layer according to the displayed layer and the request layer; sending the target rendering layer to the current client for rendering through the first communication connection; calling a collaboration service to send the target rendering layer to other clients that have subscribed to the current view for rendering through a second communication connection, so that the rendering effects of the other clients and the current client for the current view are consistent, wherein the second communication connection is used for communication between the other clients and the server.

[0034] Figure 1 An exemplary system architecture 100 to which the layer rendering method according to embodiments of the present disclosure can be applied is schematically shown. It should be noted that, Figure 1 The system architecture shown is only an example of a system architecture to which embodiments of the present disclosure can be applied, to help those skilled in the art understand the technical content of the present disclosure, but does not mean that embodiments of the present disclosure cannot be used in other devices, systems, environments or scenarios.

[0035] As Figure 1As shown, the system architecture 100 according to this embodiment can include a first terminal device 101, a second terminal device 102, a third terminal device 103, a network 104, and a server 105. The network 104 is a medium for providing communication links between the first terminal device 101, the second terminal device 102, the third terminal device 103, and the server 105. The network 104 can include various connection types, such as wired and / or wireless communication links, etc.

[0036] A user can use the first terminal device 101, the second terminal device 102, the third terminal device 103 to interact with the server 105 through the network 104 to receive or send messages, etc. Various communication client applications can be installed on the first terminal device 101, the second terminal device 102, the third terminal device 103, such as shopping applications, web browser applications, search applications, instant messaging tools, email clients, and / or social platform software, etc. (only as examples).

[0037] The first terminal device 101, the second terminal device 102, the third terminal device 103 can be various electronic devices with display screens and supporting web browsing, including but not limited to smartphones, tablet computers, laptop computers, desktop computers, etc.

[0038] The server 105 can be a server providing various services, such as a background management server providing support for websites browsed by users using the first terminal device 101, the second terminal device 102, the third terminal device 103 (only as an example). The background management server can analyze and process received user requests and other data, and feed back the processing results (such as web pages, information, or data generated or obtained according to user requests, etc.) to the terminal device.

[0039] It should be noted that the layer rendering method provided by the embodiments of the present disclosure can generally be executed by the server 105. Accordingly, the layer rendering apparatus provided by the embodiments of the present disclosure can generally be arranged in the server 105. The layer rendering method provided by the embodiments of the present disclosure can also be executed by a server or a server cluster different from the server 105 and capable of communicating with the first terminal device 101, the second terminal device 102, the third terminal device 103 and / or the server 105. Accordingly, the layer rendering apparatus provided by the embodiments of the present disclosure can also be arranged in a server or a server cluster different from the server 105 and capable of communicating with the first terminal device 101, the second terminal device 102, the third terminal device 103 and / or the server 105. Alternatively, the layer rendering method provided by the embodiments of the present disclosure can also be executed by the first terminal device 101, the second terminal device 102 or the third terminal device 103, or by other terminal devices different from the first terminal device 101, the second terminal device 102 or the third terminal device 103. Accordingly, the layer rendering apparatus provided by the embodiments of the present disclosure can also be arranged in the first terminal device 101, the second terminal device 102 or the third terminal device 103, or in other terminal devices different from the first terminal device 101, the second terminal device 102 or the third terminal device 103.

[0040] For example, the layer operation request can originally be stored in any one of the first terminal device 101, the second terminal device 102 or the third terminal device 103 (for example, the first terminal device 101, but not limited thereto), or on an external storage device and can be imported into the first terminal device 101. Then, the first terminal device 101 can execute the layer rendering method provided by the embodiments of the present disclosure locally, or send the layer operation request to other terminal devices, servers or server clusters, and execute the layer rendering method provided by the embodiments of the present disclosure by other terminal devices, servers or server clusters receiving the layer operation request.

[0041] It should be understood that Figure 1 The number of terminal devices, networks and servers in the system is only illustrative. According to the needs of implementation, there can be any number of terminal devices, networks and servers.

[0042] Figure 2 A flowchart of a layer rendering method according to an embodiment of the present disclosure is schematically shown.

[0043] As Figure 2 shown, the method includes operations S201-S203.

[0044] In operation S201, in response to receiving a layer operation request for an existing layer in a current view based on a first communication connection, the layer operation request is analyzed to determine a request layer for which the request operation is requested, wherein the current view includes a displayed layer, and the first communication connection is used for communication between the current client and the server.

[0045] According to an embodiment of the present disclosure, the current view can represent a visual page in various application software of the current client for a user to watch and / or operate. The existing layer can represent a layer configured in the current view, which is not displayed or displayed in the current view. For a layer checked by the user in the current view, it can be displayed in the current view, and such a layer can be referred to as a displayed layer. For a layer not checked by the user in the current view, it can be hidden in the current view until it is checked and displayed.

[0046] According to an embodiment of the present disclosure, the layer operation request can include at least one of the following: a check request for displaying a layer, an uncheck request for not displaying a layer, and the like, and can not be limited thereto. By analyzing the request content of the layer operation request, the request layer can include at least one of the following: a request display layer for which a check request is requested, a request not to display a layer for which an uncheck request is requested, and the like, and can not be limited thereto.

[0047] In operation S202, a target rendering layer is calculated according to the displayed layer and the request layer.

[0048] According to an embodiment of the present disclosure, the target rendering layer can represent a layer that needs to be finally displayed in the current view. In the case where the request layer is a request not to display a layer, the target rendering layer can represent a layer remaining after the request not to display a layer is deleted from the displayed layer. In the case where the request layer is a request to display a layer, the target rendering layer can represent an updated layer after the request to display a layer is added to the displayed layer. In the case where the request layer includes a request to display a layer and a request not to display a layer, the target rendering layer can be determined based on a combination of the above two manners.

[0049] It should be noted that in the process of determining the target rendering layer, other limiting conditions related to limiting layer display can also be considered. For example, in the process of determining the above-mentioned target rendering layer, if there are some invalid layers, the invalid layers can be filtered out.

[0050] In operation S203, the target rendering layer is sent to the current client for rendering through the first communication connection.

[0051] In operation S204, the collaborative service is invoked to send the target rendering layer to other clients that have subscribed to the current view for rendering through a second communication connection, so that the rendering effects of the other clients and the current client for the current view are consistent, wherein the second communication connection is used for communication between the other clients and the server.

[0052] Taking the calendar layer as an example, Figure 3 A schematic diagram of a calendar multi-layer multi-end core design according to an embodiment of the present disclosure is schematically shown.

[0053] As Figure 3 shown, the calendar client 310 can be taken as the above-mentioned current client, the calendar view 311 therein can be taken as the above-mentioned current view, and the calendar list 312 can be taken as the layer list of the above-mentioned existing layers. The user operates the calendar client 310 to open the calendar view 311, and the calendar list 312 configured in the calendar view 311 can be displayed. At the same time, the calendar client 310 can establish a WebSocket long connection with the calendar server 320, i.e., the above-mentioned first communication connection.

[0054] After the user selects and checks / unchecks the calendar layer in the calendar list 312, the calendar multi-layer processing 321 of the calendar server 320 can be invoked to perform the above-mentioned operation S202 to calculate the target rendering layer.

[0055] In a specific embodiment, the calculation principle of the calendar multi-layer processing 321 can include but is not limited to the following specific calculation method: the calendar layer display Id table can provide the selected calendar Id list Y as the displayed layers. Based on the layer operation request of the calendar client 310, at least one of the newly checked layer, the unchecked layer, and the invalid layer can be calculated.

[0056] For the newly checked layer, in the case where the maximum number of displayable layers in the current view is limited, the number of checkable layers X can be calculated as the number of remaining displayable layers first, and then the corresponding newly checked layer information list A can be queried based on the newly checked layer. In the case where the maximum number of displayable layers in the current view is not limited, the corresponding newly checked layer information list A can be directly queried based on the newly checked layer, which is not limited here.

[0057] For the unchecked layer, the calculation method can be: the intersection B of the request cancellation layer list and the valid Y. B is the final determined unchecked layer information list.

[0058] For the invalid layer, the calculation manner can be: checking C1 of the request invalid layer, checking C2 of the Y invalid layer, and C=C1+C2. Wherein, C1 can represent the request invalid layer, C2 can represent the already displayed invalid layer, and the combination C can represent the determined invalid layer information list.

[0059] Finally, combining Result=A+B+C, the Result result is returned to the calendar client 310 for calendar layer update rendering 313 to complete the above operation S203. Wherein, Result can represent the finally determined target rendering layer.

[0060] At the same time, the collaborative service can also be called for collaborative processing 322 to execute the above operation S204, including: sending Result to the calendar cloud MQ (Message Queue). The calendar server 320 can pre-subscribe to the MQ, so as to be able to receive the Result information sent by the subscribed MQ, and push the Result to the online client through the WebSocket (a kind of network protocol) long connection. Wherein, the online client can represent the above other client, and the online client can realize calendar layer update rendering after receiving the calendar layer update Result information, which is the same as the processing flow in the calendar client 310.

[0061] Corresponding to the above collaborative service, Figure 4 The flowchart of the calendar layer multi-end collaborative design according to the embodiment of the present disclosure is schematically shown.

[0062] As Figure 4 shown, the method includes first performing operation S401 between the user and the calendar client 410. Then, operations S411-S418 are performed between the calendar client 410 and the calendar server 420. After that, operations S431-S434 are performed between the calendar server 420 and the calendar cloud MQ service 430. Finally, operations S421-S422 are performed between the calendar server 420 and the calendar client 410.

[0063] In operation S401, the calendar view is accessed.

[0064] In operation S411, the long connection is subscribed.

[0065] In operation S412, the WebSocket connection is returned.

[0066] Wherein, operations S411-S412 can be used to establish the communication connection between the calendar client 410 and the calendar server 420. In the case that the calendar client 410 includes the above current client and other client, the communication connection can include the above first communication connection and second communication connection.

[0067] In operation S413, a calendar list is queried.

[0068] In operation S414, calendar list information and a corresponding selected calendar layer display Id table are returned.

[0069] In operation S415, multiple calendar layers are checked and multiple calendar layers are unchecked.

[0070] In operation S416, a calendar multi-layer display processing interface is called.

[0071] The calendar multi-layer display processing interface can be used to send a layer operation request of the calendar client 410 to the calendar server 420.

[0072] In operation S417, the calendar server 420 generates a result result=added calendar layer display list, canceled calendar layer Id list, and invalid calendar layer Id list through calculation.

[0073] In operation S418, the result result is returned.

[0074] The operations S413-S418 can be used to support the implementation of the above operations S201-S203.

[0075] In operation S431, a calendar collaboration service is called.

[0076] In operation S432, the result is sent to the calendar cloud MQ.

[0077] In operation S433, the collaboration cloud MQ is subscribed.

[0078] In operation S434, the calendar WebSocket long connection service is called, and the result is pushed to other online clients.

[0079] The calendar server 420 receives the result information based on operation S433, and performs operation S434.

[0080] In operation S421, other clients are notified to accept the result of the calendar multi-layer display processing.

[0081] In operation S422, the calendar client 410 performs calendar layer update rendering according to the returned data.

[0082] The operations S421-S422 and the operations S431-S434 can be used to support the implementation of the above operation S204.

[0083] Through the above embodiments of the disclosure, since the layer operation request of the current view on the current client is uniformly processed on the server, and the collaborative update of the current view subscribed on other clients is realized by calling the collaboration service, the problem of inconsistent display of the same view layer in different clients can be at least partially solved, the client can be ensured to update the layer change in time, and the user experience can be improved.

[0084] Based on the above method, in the case that there are multiple current clients, by uniformly processing the layer operation request on different clients on the server, the combined processing of the operation request on different ends can be realized, and a unified result can be output for collaborative update on different clients, the overlay update between different client operations is reduced, and the user experience is improved.

[0085] The inventors have also found that when a certain calendar is invalid, there is a problem of inconsistent display in different clients. For example, different terminals have opened the calendar view in turn, and can see a certain calendar X. At this time, the calendar X is invalid, and when one of the terminals reenters the calendar view, the calendar X cannot be seen in the calendar list, but the other terminal can still see the calendar X without reentering the calendar view. This will confuse the user and affect the user experience. In addition, the system does not limit the maximum upper limit of the displayable calendar, and when a user has selected a large number of calendars, the calendar layer information query corresponding to the calendar will be very slow, affecting the experience.

[0086] To further describe the working principle of the above layer rendering method in combination with the calendar multi-layer multi-end collaboration mechanism, first of all, based on the above method Figure 5 The use case structure of the calendar multi-layer multi-end collaboration mechanism according to the disclosed embodiments is schematically shown.

[0087] As shown in the above method Figure 5 The use case structure of the calendar multi-layer multi-end collaboration 500 describes the application scenario 510 of the above layer rendering method, the applicable client 520, the executable operation 530, the display calculation 540, the display cancellation calculation 550, the invalid layer calculation 560, and the collaboration control 570. The application scenario 510 can include a meeting calendar 511, a to-do task calendar 512, other schedule calendars 513, and the like, and can not be limited thereto. The client 520 can include a PC end 521, a mobile phone end 522, a tablet end 523, and the like. The operation 530 can include checking a layer 531 and unchecking a layer 532. The display calculation 540 can include a maximum displayable number 541 and a new display 542. The display cancellation calculation 550 can include an effective cancellation 551. The invalid layer calculation 560 can include an invalid selected layer in the database 561 and a request to display or cancel the display of the layer 562. The collaboration control 570 can include control for multiple ends 571 and / or the same user 572, and the like.

[0088] Based on the above use case structure, Figure 6 A flow chart of a calendar multi-layer multi-end core computing design according to the disclosed embodiments is schematically shown.

[0089] As Figure 6 shown, the method includes first performing data preparation based on operation S601~operation S609 to obtain the exhibited layers and the request layers described in operation S201.

[0090] In operation S601, the user operates the calendar layers through the calendar client.

[0091] In operation S602, the multiple calendar layers are checked and the multiple calendar layers are unchecked.

[0092] In operation S603, the calendar multi-layer exhibition processing interface is called.

[0093] Wherein, after the calendar server receives the call request, operation S604 is performed first.

[0094] In operation S604, the retryable distributed lock is obtained.

[0095] Wherein, after the calendar server successfully acquires the lock, operation S605~operation S608 can be performed based on the calendar multi-layer service.

[0096] In operation S605, the calendar layer Id list exhibited by the user is queried.

[0097] In operation S606, the exhibited calendar layer Id list is queried from the calendar layer exhibition Id table.

Subtracting the invalid displayed layers from the set of displayed layers yields the set of valid displayed layers; The intersection of the request not to display the layer and the already displayed valid layers is the result of the request to cancel displaying the valid layers. The remaining valid layers that have been displayed are obtained by subtracting the requested layers that were canceled from the set of displayed valid layers. The target rendering layer is determined based on the requested valid display layers and the remaining valid display layers.

5. The method according to claim 4, wherein, The step of determining the target rendering layer based on the requested valid display layer and the remaining valid display layers includes: The remaining number of displayable layers is obtained by subtracting the number of remaining valid layers that have already been displayed from the maximum number of displayable layers configured for the current view; Get the list of newly added display layers, where the initial value of the number of newly added displays in the list is 0; In response to determining that the number of newly added displays has not reached the number of remaining displayable layers, the target requested valid display layer is read from the requested valid display layers; In response to determining that the target request valid display layer does not exist in the remaining valid display layers, the target request valid display layer is added to the list of newly added display layers, and the number of newly added displays is incremented by 1; In response to determining that the number of newly added displays has reached the number of remaining displayable layers, the newly added display layers in the list of newly added display layers and the remaining valid display layers are assembled to obtain the target rendering layer.

6. The method according to any one of claims 1-5, wherein, The target rendering layer includes at least one of the following: a newly added display layer, a request to cancel the display of valid layers, and a total of invalid layers; the method further includes: The newly added display layer will be displayed in the current view; The request will hide the valid layers in the current view; Remove the total failure layer from the current view.

7. A layer rendering apparatus, comprising: The request analysis module is used to respond to a layer operation request received via a first communication connection for an existing layer in the current view, analyze the layer operation request, and determine the requested layer for the operation. The current view represents the view in the current client, and the current view includes the displayed layers. The first communication connection is used for communication between the server and the current client. The target rendering layer calculation module is used to calculate the target rendering layer based on the displayed layer and the requested layer; The rendering module is used to send the target rendering layer to the current client for rendering via the first communication connection; The collaboration module is used to invoke the collaboration service and send the target rendering layer to other clients that have subscribed to the current view for rendering through a second communication connection, so that the rendering effect of the current view on the other clients and the current client is consistent. The second communication connection is used for communication between the other clients and the server.

8. An electronic device, comprising: One or more processors; Memory, used to store one or more programs. When the one or more programs are executed by the one or more processors, the one or more processors implement the method of any one of claims 1-6.

9. A computer-readable storage medium having executable instructions stored thereon, which, when executed by a processor, cause the processor to perform the method of any one of claims 1-6.

10. A computer program product comprising a computer program that, when executed by a processor, implements the method according to any one of claims 1-6.
