[0038] Before introducing this application, the English terms involved in this article are explained first:

[0039] Ajax request: A technology that can update part of a web page without reloading the entire page. It initiates asynchronous requests through JavaScript, obtains data from the server, and dynamically displays the data on the page.

[0040] WebSocket request: A network communication protocol that provides the ability to perform full-duplex communication on a single TCP connection. It allows the server to actively send messages to the client without the client constantly polling the server.

[0041] JavaScript file: Also known as JS file, it is a script file with a .js extension that contains code written in JavaScript and is used to enhance the interactivity and dynamic functionality of web pages on the client side. These files make web page design neater, avoid HTML document clutter through external references, and support modular programming for easy code maintenance and reuse.

[0042] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0043] The present application provides a data transmission method. When the client initiates a data transmission request, the custom tags in the page template are triggered, and the tag processor then identifies the attributes of these tags to determine whether the transmitted data needs to be encrypted. If the tag attributes indicate that encryption is required, the system will load a pre-configured encryption file, and use the encryption rules and keys in the file to encrypt the target data in the data transmission request to generate encrypted data. Finally, the encrypted data is securely sent to the server, ensuring the security and integrity of the data during transmission, and effectively preventing the leakage of sensitive information and potential network attacks.

[0044] The present application solution can be implemented based on a terminal with data processing capabilities, which can be a mobile phone, computer, server, etc.

[0045] Next, see Figure 1 , a flow chart of a data transmission method provided by the present application, the data transmission method of the present application can be implemented by a data transmission system deployed on a terminal, as described below, specifically including the following steps:

[0046] Step S100: When a data transmission request of a client page is monitored, a custom tag in a page template is triggered. After the custom tag is triggered, a tag attribute of the custom tag is identified by a tag processor.

[0047] Specifically, when a client user initiates a data transfer request in the client, such as clicking a link, submitting a form, or initiating a request, the custom tags in the page template will be triggered. These custom tags are pre-designed and embedded in the page template to execute specific logic when specific events occur. Once these custom tags are triggered, the tag processor will intervene. Its role is to identify the properties of these custom tags, which define the behavior and function of the tags. In this process, the tag processor will check the name and properties of the tag, and then perform corresponding operations based on these properties.

[0048] Step S110, determining whether the tag attribute indicates that the data needs to be encrypted, if so, executing step S120.

[0049] Specifically, when a data transmission request of a client page is detected, a custom tag in the page template will be triggered. This custom tag has a specific attribute, which is used to identify whether the data to be transmitted needs to be encrypted. If the attribute is set to indicate that encryption is required, the configured encryption file is loaded and the target data carried in the data transmission request is obtained using the encryption file.

[0050] In this way, the custom tag and tag processor not only respond to the client's data transmission request, but also encrypt the data as needed, enhancing the security of data transmission. This process is automated and transparent to the user, and does not require any additional operation by the user.

[0051] Step S120: Load the configured encrypted file, and use the encrypted file to obtain the target data carried in the data transmission request.

[0052] Specifically, once the system determines that the data needs to be encrypted, it will execute the operation of loading the configured encryption file. The system will load the pre-configured encryption file, which can be a JS file. When the encryption file is successfully loaded, the system will use the encryption file to obtain the target data carried in the data transmission request initiated by the client. This data can be information entered by the user, content submitted by the form, or content sent through a request. Obtaining the data transmitted by the user through a pre-configured encryption file solves the problem of difficulty in data acquisition, and also ensures the security of the data during transmission, preventing the data from being intercepted or tampered with when it is transmitted between the client and the server.

[0053] Step S130: encrypt the target data to obtain encrypted data, and send the encrypted data to the server.

[0054] Specifically, when the data transmission request of the client page is monitored and the system determines that the data needs to be encrypted, the encryption process will be started. The system will encrypt the target data such as the information entered by the user, the content submitted by the form, or the content sent by the request to obtain encrypted data. Subsequently, the encrypted data will be sent to the server through a secure network channel to ensure that the security and privacy of the data are protected during the transmission process, and prevent the data from being intercepted or tampered by unauthorized third parties during the transmission process.

[0055] The data transmission method of the present application, when monitoring the data transmission request of the client page, will trigger the custom tags in the page template, and identify the attributes of these tags through the tag processor to determine whether the data needs to be encrypted. If the tag attribute indicates that encryption is required, the system will automatically load the configured encryption file and use the file to obtain the target data carried in the data transmission request. The tag attributes of the custom tag can be configured and adjusted as needed, which can flexibly respond to different security requirements, and is also easy to expand and maintain. By integrating custom tags in the client page template, the encryption process can be automatically triggered when a data transmission request occurs, solving the problem of data acquisition difficulties. The target data is then encrypted, and the encrypted data is generated and sent to the server. This method improves the confidentiality and integrity of the data, not only preventing the data from being intercepted and tampered with during transmission, but also effectively preventing the leakage of sensitive information and potential network attacks.

[0056] Further, in some embodiments of the present application, after the system sends the encrypted data to the server, the feedback data transmitted by the server is obtained, and the feedback data can be processed by the template engine, see Figure 2 , Figure 2 A schematic diagram of the workflow of a template engine provided in an embodiment of the present application. The following is an introduction to this part:

[0057] Optionally, once the server has finished processing the encrypted data sent by the client, it will generate feedback data and send it back to the client, at which point the template engine will be used to process the feedback data. The template engine plays an important role in dynamically rendering the data to the client page.

[0058] like Figure 2 As shown in the figure, the template engine uses predefined page templates that contain custom tags and placeholders for dynamically filling data. When the feedback data arrives at the client, the template engine will identify the custom tags and placeholders in these page templates and fill these locations with the corresponding content in the feedback data. For example, if the feedback data contains user information or transaction results, the template engine will accurately place this information in the corresponding position of the page template. By utilizing the template engine to parse and apply the feedback data, it combines the data with the page template to generate the final client page.

[0059] This embodiment uses the template engine to analyze and apply the feedback data, combines the feedback data with the page template, and generates the final client page, so that the result processed by the server is displayed on the client page, while maintaining the dynamic and interactive nature of the page. The use of the template engine improves the efficiency of page generation and makes the development and maintenance of the client page simpler and more flexible. In this way, the real-time, security and accuracy of the data are ensured.

[0060] Further, in some embodiments of the present application, in order to realize the monitoring and processing of the data transmission request of the client page, a series of preliminary preparations may be performed before this, and this part is introduced below:

[0061] Optionally, in the backend development framework of the system, you first need to introduce the template engine starter dependency package, which is required to start and configure the template engine. This dependency package contains all the libraries and resources required for the template engine to run. Next, you need to modify the basic configuration file to set the parameters of the template engine. This can include specifying the storage path of the template file, whether to enable caching to improve performance, and the encoding format of the template, etc., to ensure that the template engine can correctly parse and render the page template.

[0062] In order to extend the functionality of the template engine and use custom tags, you need to create a custom tag registration class. The purpose of this class is to define the name and tag attributes of new custom tags, which will be used to perform specific functions in the template, such as data encryption or dynamic content insertion. Corresponding to each custom tag registration class is a tag processor class. The tag processor class is responsible for identifying the name and attributes of the custom tag, and adding corresponding event processing logic to the client page based on these attributes. These events can include operations such as data acquisition, encryption, and sending. The tag processor class ensures that the correct processing flow can be triggered when these events occur.

[0063] In this embodiment, the template engine is configured and extended to support data processing and event processing logic of custom tags. In this way, when data transmission requests from client pages are detected, the template engine is ready to process these requests and perform encryption and data transmission related operations through custom tags and processors. Thus, the entire process is automated and transparent to users, improving the security and user experience of the Web system.

[0064] Further, in some embodiments of the present application, the data may be encrypted using an encryption method specific to the present application, see Figure 3 , Figure 3 The following is a flow chart of an encryption method provided in an embodiment of the present application. The encryption method is introduced as follows:

[0065] First, the target data is divided into multiple groups of 128 bits in size. Each 128-bit data group is further divided into four 32-bit data blocks. This subdivision helps to perform more detailed operations on the data during the encryption process. At the same time, an initial key is generated using a preset algorithm. This key is the key in the encryption process. It will be used in combination with the data block and play a role in the entire encryption process. Each 32-bit data block is combined with the initial key. The data combined with the data block and the initial key is encrypted for 32 rounds. Each round can include operations such as XOR, S-box transformation, mixing and shifting. The combination of these operations increases the complexity and security of encryption. Then, after completing 32 rounds of encryption operations, the data is reversed. This step is to reorganize the data after multiple encryptions to generate the final ciphertext. To further improve security, the initial key itself also needs to be encrypted. The initial key can be encrypted using a preset algorithm to generate a random number to obtain the final key. This key will be used in the decryption process to restore the original data. Finally, the ciphertext and the key are used together as encrypted data. In this way, only the recipient with the correct key can decrypt the ciphertext and obtain the original target data.

[0066] After receiving the encrypted data, the server needs to decrypt it first. The same key is used for encryption and decryption. When decrypting, it only needs to reverse the order of the keys used for polling encryption. After obtaining the data, the server processes the data and then returns the processing results as feedback data.

[0067] This encryption method of the present embodiment provides more detailed encryption operations for the data and enhances security by dividing the target data into 128-bit groups and further subdividing them into four 32-bit data blocks. The initial key generated by the preset algorithm is combined with each data block to ensure the dynamic and unpredictable nature of the encryption. By performing 32 rounds of encryption operations, including XOR, S-box transformation, mixing and shifting, the complexity of the encryption is further increased, making it extremely difficult to crack. After completing these operations, the data will undergo a reverse transformation, which not only reorganizes the encrypted data, but also generates the final ciphertext, further ensuring the security of the data. In addition, the initial key itself also needs to be encrypted to ensure the security of the key and prevent the risk of key leakage. Ultimately, the encrypted data includes ciphertext and key, and only the recipient with the correct key can decrypt the ciphertext and restore the original data. This method not only improves the security of data transmission, but also ensures the integrity and compliance of the data, and is particularly suitable for financial transactions and sensitive information transmission with extremely high security requirements. Its flexibility and scalability also enable the encryption method to adapt to changing security threats and technological advances.

[0068] Further, in some embodiments of the present application, the determination of whether data needs to be encrypted can be made using the tag attribute value in the custom tag. The system will check the tag attribute value in the custom tag to determine whether the associated data needs to be encrypted. If the tag attribute value contains a specific identifier, it can be a Boolean value or a specific keyword. The system will determine the logic represented by the tag attribute value. For example, if the tag attribute value is true, it means that the associated data needs to be encrypted, and the system will trigger the encryption process; if the tag attribute value is false, it means that the associated data does not need to be encrypted, and the data will be transmitted according to the normal process.

[0069] In this embodiment, the decision of whether to encrypt is made by the tag attribute value, which provides a high degree of flexibility, so that the same tag can have different behaviors in different situations, allowing developers to easily set encryption rules for different data or different scenarios according to specific needs. By checking the attribute value of the custom tag to determine whether the data needs to be encrypted, the system is allowed to automatically trigger the encryption process based on the Boolean value or keyword in the tag, thereby improving efficiency and security. This setting is transparent to users, reduces human errors, simplifies maintenance, and can quickly adapt to different encryption needs while ensuring that data transmission meets compliance requirements.

[0070] Further, in some embodiments of the present application, data transmission requests cover a variety of data interaction methods that may occur in a Web system. Specifically, these requests include: general requests, Ajax requests, and WebSocket requests. These data transmission requests form the basis for data interaction between the client and the server in the Web system. In this embodiment, no matter which type of request is made, the system can ensure the security of data during transmission through custom template engine tags and improved encryption algorithms. This means that whether the user clicks on a link, submits a form, performs asynchronous data interaction, or maintains a real-time connection through WebSocket, the data involved in all these operations can be effectively encrypted and protected.
