Technical Field

[0002] With the development of front-end microservice architecture, more and more enterprise applications are adopting the micro-frontend or micro-application pattern, breaking down a large system into multiple independently running and deployable sub-applications. Each micro-application typically runs in a different environment or under a different domain, achieving business collaboration by sharing some state or data.

[0033] Figure 1 The illustration shows an application scenario diagram of the micro-application data synchronization method according to an embodiment of the present disclosure.

[0034] like Figure 1 As shown, application scenario 100 according to this embodiment may 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 serves as a medium for providing a communication link between the first terminal device 101, the second terminal device 102, the third terminal device 103, and the server 105.

[0036] The first terminal device 101, the second terminal device 102, and the third terminal device 103 can be various electronic devices with displays and support web browsing, including but not limited to smartphones, tablets, laptops, and desktop computers.

Correspondingly, the micro-application data synchronization device provided in this embodiment can also be located in a server or server cluster that is different from server 105 and capable of communicating with the first terminal device 101, the second terminal device 102, the third terminal device 103, and / or server 105.

[0039] It should be understood that Figure 1 The number of terminal devices, networks, and servers shown is merely illustrative. Depending on implementation needs, any number of terminal devices, networks, and servers can be included.

[0040] The following will be based on Figure 1 The described scene, through Figures 2-4 The micro-application data synchronization method according to the embodiments of this disclosure will be described in detail.

[0041] Figure 2A flowchart illustrating a micro-application data synchronization method according to an embodiment of the present disclosure is shown.

[0042] like Figure 2 As shown, the micro-application data synchronization method of this embodiment includes operations S210 to S240, and the micro-application data synchronization method can be executed by a server.

[0043] In operation S210, a sandbox proxy channel is constructed, which is used to establish cross-domain communication paths between different micro-applications.

[0044] In operation S220, in response to the detection of a change in the current state of the microapplication, a differential description corresponding to this change is generated. The differential description only records the content of the change that occurred this time.

[0045] In operation S230, based on the differential description, the differential description is encrypted using a pre-configured hierarchical encryption mechanism to obtain ciphertext data. The hierarchical encryption mechanism includes encrypting the business data in the differential description using a first encryption model and encrypting the encapsulated metadata corresponding to the differential description using a second encryption model.

[0046] When operating the S240, the event bus center is used to broadcast encrypted data to the specified target micro-application through the sandbox agent channel for data synchronization.

[0047] In this embodiment, a sandbox proxy channel is constructed as a cross-domain data transmission channel. During data transmission, a layered encryption mechanism is used to perform double encryption on the data to ensure security. On this basis, an event bus + differential synchronization protocol is used to synchronize only the parts where the state changes, thereby reducing the amount of data transmission and transmission latency, and improving synchronization efficiency.

[0048] For example, consider a small front-end micro-application developed using the HyperText Markup Language 5.0 (HTML5) technology stack that can run, deploy, and update independently.

[0049] First, a sandbox proxy channel is built as a cross-domain communication path between different micro-applications.

[0050] A sandbox, also known as a sandbox, is a security mechanism in the field of computer security that provides an isolated environment for running programs. The system can establish sandbox proxy channels between multiple micro-applications.

[0051] After the sandbox proxy channel is established, when the system detects a change in the state of a micro-application (e.g., a user changes settings or the interface state), the system compares the current state data of the micro-application with reference state data (which could be the state of the previous version or the initial state). For example, a structured comparison algorithm can be used to extract the differences and generate a differential description. This differential description only records the changed parts, such as modifications to a field value or the addition of new data, greatly reducing the amount of data that needs to be transmitted for synchronization.

[0052] Next, the system encrypts the differential description according to a pre-configured layered encryption mechanism. For example, firstly, a symmetric encryption algorithm can be used to encrypt the business data in the differential description to ensure the security of the business content. Secondly, a streaming encryption algorithm can be used to encrypt the metadata (such as timestamps, message headers, and signatures) in the differential description to enhance data integrity and tamper resistance.

[0053] Finally, the system utilizes the event bus center to broadcast the encrypted data to the designated target micro-application based on its subscribed topics. Upon receiving the encrypted data, the target micro-application decrypts and updates the data through the sandbox proxy channel.

[0054] According to embodiments of this disclosure, since the sandbox proxy channel can provide a secure isolation environment, and the transmitted data is further encrypted in layers, this isolation + encryption measure can effectively prevent cross-domain data leakage and greatly improve the security of cross-domain communication of the system. In addition, the event bus + differential synchronization protocol only synchronizes the changed data, which reduces the amount of data transmission and transmission latency compared to the traditional full data synchronization, and greatly improves the synchronization efficiency.

[0055] In this embodiment of the disclosure, the sandbox proxy channel is configured as a multi-layer architecture, which may include, for example:

[0056] The application layer is configured with a unified application programming interface (API), which includes a first interface for sending synchronization data to different micro-applications and a second interface for receiving synchronization data from different micro-applications. The proxy layer is configured to encrypt and encapsulate synchronization data according to a preset sandbox proxy script. The transport layer is configured to transmit synchronization data between different micro-applications according to a preset cross-domain communication mechanism.

[0057] In this embodiment, a three-layer separation architecture is introduced to decouple micro-applications from the underlying communication mechanism, enabling the application layer to securely transmit data through a unified interface. See details... Figure 3 As shown.

[0058] Figure 3 A schematic diagram of a multi-layer architecture of a sandbox proxy channel according to an embodiment of the present disclosure is shown.

[0059] like Figure 3 As shown in this embodiment, the sandbox proxy channel adopts a three-layer architecture, namely the application layer, the proxy layer, and the transport layer. The functions of each layer are as follows:

[0060] The application layer provides a unified Application Programming Interface (API) for micro-applications. This API includes two main functions:

[0061] Send function: Used to send synchronization data. The parameters passed in include the target micro-application identifier, the synchronization data, and the operation type. When this API is called, the system passes the data to the proxy layer for encryption and encapsulation.

[0062] Receive function: Used to receive synchronized data from other micro-applications. The system will automatically decrypt the data and pass it to the application layer for processing.

[0063] The proxy layer is responsible for encrypting, signing, and encapsulating data according to the sandbox proxy script. In addition to performing data encryption, the proxy layer also performs whitelist verification on each synchronized data message to ensure the message source is trustworthy. If the message source is not on the whitelist, the message will be discarded.

[0064] The transport layer provides different cross-domain communication mechanisms and supports multiple communication protocols. Depending on the deployment environment of the micro-application, the system can select a suitable transport channel.

[0065] According to embodiments of this disclosure, this three-tier architecture design decouples the application layer from the underlying communication mechanism, allowing the system to flexibly select different communication methods while ensuring data security and transmission efficiency.

[0066] In this embodiment of the disclosure, the transport layer is configured with a plurality of sub-channels, which may include, for example:

[0067] Cross-application messaging channels are used for cross-domain message transmission between different micro-applications; context broadcast channels are used for same-domain message transmission between multiple different pages within the same micro-application; and bridging channels are used for cross-domain message transmission between the main application and its sub-applications.

[0068] In this embodiment of the disclosure, a multi-channel hybrid communication mechanism is integrated to meet the multi-layer communication needs under cross-domain, same-domain, and master-slave relationships through the collaboration of different channels.

[0069] For example, you can choose to use cross-application messaging channels to enable cross-domain message transmission between different micro-applications.

[0070] Each micro-application specifies a target domain during registration and sends encrypted messages to micro-applications on that domain via a cross-application messaging channel. Message sending and receiving are encrypted and verified through a sandboxed proxy channel to ensure data security.

[0071] Alternatively, a context broadcast channel can be used to transmit synchronized data between multiple pages from the same origin. Each page acts as an independent context, and this channel can be used to broadcast and synchronize messages. This channel is suitable for rapid collaboration and data synchronization between micro-applications from the same origin, offering low latency and high efficiency.

[0072] A bridging channel can also be used to enable cross-domain message transmission between the main application and sub-applications. The main application loads the sub-application through an embedded bridging function and transmits encrypted data to the sub-application via a cross-application messaging channel. Upon receiving the data, the sub-application decrypts it and updates its state. This approach is suitable for embedded micro-application collaboration scenarios.

[0073] The system can automatically select the most suitable sub-channel based on the actual communication scenario to optimize data transmission performance.

[0074] According to embodiments of this disclosure, by flexibly selecting sub-channels, efficient transmission and isolation of cross-domain and same-domain messages can be achieved, significantly improving the system's compatibility, transmission performance, and security.

[0075] In this embodiment of the disclosure, operation S220, in response to detecting a change in the current state of the micro-application, generates a differential description corresponding to this change, which may include, for example:

[0076] In response to the detection of a change in the current state of the micro-application, the current state data of the micro-application is compared in a structured manner with the reference state data before the change; based on the comparison results, a differential description conforming to the requirements of the differential synchronization protocol is generated in a preset format.

[0077] In this embodiment of the disclosure, a structured comparison algorithm is introduced to automatically generate differential descriptions, ensuring that the transmission of synchronous data is minimized.

[0078] For example, when a change in the state of a micro-application is detected, the system first performs a structured comparison between the current state data of the micro-application and the reference state data. For instance, the system first loads the current state data of the micro-application (such as UI state, configuration files, etc.) and compares it with the previously saved reference state. During the comparison process, the system uses a structured difference algorithm (such as JSON Diff) to compare the differences between the two.

[0079] Then, based on the comparison results, the system extracts only the changed data and generates a differential description according to a preset format (such as JSONPatch format). This differential description includes the changed fields, the operation type (add, modify, delete), and the changed value. The generated differential description conforms to the requirements of the differential synchronization protocol, ensuring minimal and efficient data synchronization.

[0080] The synchronization protocol standardizes the format and transmission method of each change operation, ensuring that data can be correctly synchronized between different micro-applications.

[0081] According to embodiments of this disclosure, compared to traditional full data synchronization, this method only synchronizes the changed parts, effectively reducing transmission overhead, improving efficiency, and supporting real-time synchronization scenarios for large-scale micro-applications.

[0082] In this embodiment of the disclosure, operation S230 encrypts the differential description using a pre-configured hierarchical encryption mechanism to obtain ciphertext data, which may include, for example:

[0083] The business data in the differential description is encrypted using a symmetric encryption algorithm, where the symmetric encryption algorithm represents the first encryption model; the encapsulated metadata corresponding to the differential description is encrypted using a streaming encryption algorithm, where the streaming encryption algorithm represents the second encryption model.

[0084] In this embodiment, an innovative layered encryption mechanism is proposed to encrypt business data and metadata separately, thereby improving the security and integrity of data transmission.

[0085] For example, after the differential description is generated, the system performs layered encryption to ensure high data security during transmission.

[0086] First, the primary encryption model, namely a symmetric encryption algorithm (such as the Block Cipher Standard or the Advanced Encryption Standard), is used to symmetrically encrypt the business data in the differential description. Symmetric encryption algorithms ensure the efficiency of the encryption and decryption process and are suitable for encrypting large amounts of business data.

[0087] Then, a second encryption model, namely streaming encryption, is used to stream-encrypt the encapsulated metadata (such as timestamps, message headers, signatures, etc.) in the differential description. Streaming encryption offers higher security and ensures the integrity and tamper-proof capability of the encryption process.

[0088] Finally, the system generates a complete encrypted data packet, which includes encrypted business data and metadata. The encrypted data packet is then sent to the target micro-application via a sandboxed proxy channel.

[0089] According to embodiments of this disclosure, the layered encryption mechanism provides dual protection for both data content and encapsulated information, preventing both the leakage of business data and the tampering of message packets, thereby improving the overall communication security level.

[0090] In this embodiment of the disclosure, operation S240 utilizes the event bus center to broadcast encrypted data to a designated target micro-application via a sandbox proxy channel for data synchronization. This may include, for example:

[0091] Using the event bus center, it detects whether the encrypted data matches the subscribed topics of each micro-application; in response to the encrypted data matching the subscribed topics, it broadcasts the encrypted data to the matching target micro-application through the sandbox proxy channel for data synchronization.

[0092] In this embodiment of the disclosure, an encrypted data broadcasting mechanism based on topic matching is introduced at the event bus center.

[0093] The event bus center maintains a table of subscribed topics for all microapplications. For example, when a sandbox proxy channel receives encrypted data, the event bus center matches the topic field of the encrypted data to see if any microapplication has subscribed to that topic. Each microapplication declares the types of topics it subscribes to when it registers.

[0094] If the topic of the encrypted data matches the subscription topic of a microapplication, the event bus center will broadcast the encrypted data to the target microapplication through the sandbox proxy channel. Upon receiving the data, the target microapplication will automatically decrypt it and perform the corresponding status update.

[0095] According to embodiments of this disclosure, the mechanism enables precise broadcasting, sending messages only to micro-applications with subscription relationships, avoiding redundant transmission, and improving message distribution efficiency and system security.

[0096] In this embodiment of the disclosure, the micro-application data synchronization method may further include, for example:

[0097] The foldable screen sensor detects changes in the screen angle of each micro-application; based on the changes in screen angle, the corresponding collaboration mode is switched to support multi-screen interaction scenarios.

[0098] In this embodiment, device sensor information (folding angle) is dynamically bound to a micro-application collaboration mode to achieve adaptive interaction, as detailed below. Figure 4 As shown.

[0099] Figure 4 The illustration depicts a scenario of multi-screen interaction according to an embodiment of the present disclosure.

[0100] like Figure 4As shown in this embodiment of the disclosure, in the foldable screen device, the system detects changes in screen angle in real time through a foldable screen sensor. For example, the foldable screen device has a built-in sensor that monitors the hinge angle of the screen in real time.

[0101] When a change in screen state is detected (such as from unfolded to folded or half-folded), the sensor will transmit angle data.

[0102] Based on the changing angle of the foldable screen, the system can dynamically switch the collaboration mode of micro-applications, for example:

[0103] Expanded mode: When the screen angle approaches 180°, the system switches to multi-window collaboration mode, where multiple micro-applications are displayed side by side, supporting efficient multitasking.

[0104] Half-fold mode: When the screen angle is close to 90°, the system switches to a split-screen mode, with the upper screen displaying the main content and the lower screen displaying auxiliary functions or the operation interface.

[0105] Folding mode: When the screen angle is close to 0°, the system switches to single application focus mode, displaying only the main micro-application interface to reduce background interference.

[0106] According to embodiments of this disclosure, the system can automatically adjust its display and interaction logic based on the device form, maintaining optimal display and interaction effects in different states such as folded, unfolded, and split-screen, thereby enhancing the system's intelligence and adaptability.

[0107] In this embodiment of the disclosure, the corresponding collaboration mode is switched according to the change of screen angle to support multi-screen interaction scenarios, which may include, for example:

[0108] In response to detecting that the screen angle is less than a preset threshold, switch to tile mode; in response to detecting that the screen angle is greater than a preset threshold, switch to split-screen mode.

[0109] In this embodiment of the disclosure, a collaborative interface adaptive mechanism for multiple micro-applications is realized by dynamically switching between tiling / split-screen modes based on the screen angle.

[0110] For example, taking an HTML5 micro-application as an example, as a preferred embodiment, this disclosure combines the characteristics of the micro-application and designs two collaboration modes: tiling mode and split-screen mode.

[0111] Tiling mode:

[0112] When the screen angle is less than a preset threshold (such as 60°), the system determines that the screen is close to a folded state, and the mini-apps automatically switch to tile mode. At this time, all mini-apps are arranged compactly above the main app, supporting simple single-task interaction.

[0113] Split-screen mode:

[0114] When the screen angle exceeds a preset threshold (e.g., 100°), the system automatically switches to split-screen mode. At this time, the screen is divided into two parts: the upper screen displays the main application, and the lower screen displays auxiliary functions or other micro-applications, which is suitable for collaborative processing of multiple tasks.

[0115] According to embodiments of this disclosure, the layout and interaction logic can be automatically optimized on foldable screen devices to avoid interface stretching or occlusion issues, thereby improving the multi-screen collaboration experience and the flexibility of system human-computer interaction.

[0116] Based on the above-described micro-application data synchronization method, this disclosure also provides a micro-application data synchronization device. The following will be combined with... Figure 5 The device is described in detail.

[0117] Figure 5 A schematic block diagram of a micro-application data synchronization device according to an embodiment of the present disclosure is shown.

[0118] like Figure 5 As shown, the micro-application data synchronization device 500 of this embodiment includes: a construction module 510, a generation module 520, an encryption module 530, and a broadcast module 540.

[0119] The construction module 510 is used to construct a sandbox proxy channel, which is used to establish cross-domain communication paths between different micro-applications. In one embodiment, the construction module 510 can be used to perform the operation S210 described above, which will not be repeated here.

[0120] The generation module 520 is used to generate a differential description corresponding to the current change in the state of the microapplication in response to the detection of such a change.
