[0029] Figure 1A data transmission method provided in an embodiment of the present application includes:

[0030] Step S100, obtaining the data to be transmitted from the front end and obtaining the string transmission format.

[0031] The data to be transmitted may be data captured on the front-end page, especially some high-precision data, including but not limited to: financial data, such as stock prices, exchange rate data, transaction amounts; scientific computing data, such as physical simulation computing data, chemical analysis data, engineering computing data; medical data, such as physiological parameters, medical imaging data. The string transmission format may be a custom data transmission format. In some specific embodiments, the front end obtains the data to be transmitted from user input, forms or other data sources, the data to be transmitted may be a long data type, and the string transmission format may be a custom string format, for example, the string transmission format is "someLong":{"$int64":"999999999999"} in JSON format, indicating that the value of the "someLong" field is 9999999999999, that is, "someLong":{"$i nt64":"999999999999"} is used to represent a 64-bit integer.

[0032] Step S110 : converting the data to be transmitted into a string format to be transmitted based on the string transmission format, and generating a transmission request according to the string format to be transmitted.

[0033] Among them, the string format to be transmitted can be data in a string format for data transmission. The conversion of the data to be transmitted into the string format to be transmitted can be achieved through a custom converter, which can be used to convert one data format or type into another data format or type to meet the data exchange requirements between different systems or components. The transmission request can be a request generated by the front end when the front end and the back end interact with each other, and the data is transmitted to the back end. The transmission request can be an HTTP request or a specifically generated request file. Optionally, the data type definition of the long field can be converted into stringing according to the configuration, so that stringing can be used to circulate in the entire data transmission program, thereby avoiding the problem of precision loss. In some specific embodiments, a custom converter can be used to convert the data to be transmitted into the string format to be transmitted according to the string transmission format "someLong":{"$i nt64":"999999999999"}, for example, using a custom serializer or an existing serialization library (such as JSON.stringify), and then generate an HTTP request. The HTTP request includes a request method: such as GET, POST, PUT, DELETE, etc., the target URI of the request, the HTTP version, a request header (such as Content-Type) and the string format to be transmitted (i.e., the request body).

[0034] Step S120, sending the transmission request to the back end.

[0035] Optionally, you can use a browser (for example, through form submission), a command line tool (such as curl or wget), an HTTP library in a programming language (such as JavaScript's fetch API or XMLHttpRequest), or use an API testing tool such as Postman to send the HTTP transmission request to the backend for processing.

[0036] Step S130: a preset interceptor at the back end intercepts the transmission request and verifies the format of the string to be transmitted. If the verification passes, the format of the string to be transmitted is deserialized to obtain deserialized data.

[0037] Among them, the preset interceptor can be a front-end request interceptor, which is used to process the transmission request before the front end sends it to the back end. For example, the preset interceptor can be an axios request interceptor. Deserialized data can be data obtained by serializing and inversely processing the string format to be transmitted. Optionally, the back end uses a preset interceptor to verify whether the request body (i.e., the string format to be transmitted) in the transmission request meets the expected string transmission format requirements (i.e., the string transmission format). If it meets the requirements, the next step is processed. If it does not meet the requirements, the string format to be transmitted is intercepted to ensure the consistency of data transmission between the front and back ends, and prevent data corruption or malicious attacks. When the verification passes, a custom deserializer or an existing deserialization library (such as JSON.parse) can be used to deserialize the data transmission format (such as JSON) in the request body into a data type that the back end can recognize, such as converting a string to a long type, and obtaining deserialized data.

[0038] Step S140, responding to the deserialized data according to the preset middleware to generate response data.

[0039] Among them, the preset middleware is a pre-set function used in the request processing pipeline, which can access the request object (req), the response object (res) and the next middleware function (next) in the pipeline. The response string format is a digital transmission format consistent with the string transmission format. Optionally, the preset middleware can be added at the program entry of the JavaScript backend (especially Node.js application). The response data can be the data generated by the middleware in response to the data transmitted by the front end according to business needs. In some specific embodiments, the preset middleware can be used to process the deserialized data, and the corresponding operations such as database query, data calculation, etc. can be performed at the back end according to specific business needs, thereby generating corresponding response data.

[0040] Step S150: convert the response data into a response string format according to the preset middleware.

[0041] Optionally, to ensure consistency and accuracy of data transmission between the front-end and back-end, the response data should also be formatted accordingly when the back-end transmits data to the front-end, and the response data should be converted into an appropriate format (such as JSON). For example, the response data can be converted into the "someLong" format to obtain the response string format, thereby ensuring that high-precision values ​​can be correctly transmitted and processed, thereby avoiding the problem of precision loss caused by data type conversion.

[0042] Step S160, sending the transmission response string format back to the front end.

[0043] Optionally, after the backend responds, the transmission response string format can be sent back to the frontend, and the frontend can receive the response string format and perform corresponding data processing and display.

[0044] The above data transmission method can ensure the accuracy of data transmission, improve system compatibility, improve development efficiency, and achieve efficient and easy-to-use data transmission effect.

[0045] In some specific embodiments of the present application, after the preset interceptor at the back end intercepts the transmission request and performs verification, it also includes:

[0046] If the verification fails, an error response is returned to the front end.

[0047] Among them, the error response is a special response returned by the server or system to the front end when the transmission request cannot be successfully transmitted to the back end. The error response contains information about the cause of the error, the error type, and how to solve the error. Optionally, if the preset interceptor fails to verify the format of the string to be transmitted in the transmission request, that is, the format of the string to be transmitted does not meet the string transmission format requirements, it means that the data is damaged or maliciously attacked. At this time, an error response can be generated and include error information.

[0048] In some specific embodiments of the present application, the data transmission method further includes:

[0049] The front end reads the response string format and converts the response string format into display data.

[0050] In some specific embodiments, the front end receives a response (e.g., an HTTP response) and can read the data in the response body (i.e., the corresponding string format). If the response data is in JSON format, JSON.parse can be used to convert it into a JavaScript object or data structure to obtain display data.

[0051] Update the front-end display content according to the response data.

[0052] Optionally, the received display data may be processed using front-end logic and displayed to the user for review, such as updating page content, displaying prompt information, etc.

[0053] In some specific embodiments of the present application, before generating a transmission request according to the format of the data to be transmitted, the method further includes:

[0054] Encrypt the request string and generate a data encryption identifier.

[0055] Among them, the data encryption identifier can be a mark or symbol generated after encrypting the request string using an encryption algorithm, which is used to indicate that the request string data has been encrypted. The data encryption identifier can be used to verify the integrity of the data later. In some specific embodiments, after the front end converts the data into a request string, it is not transmitted directly, but the data is first encrypted to protect the confidentiality of the data and prevent unauthorized access and leakage. For example, a symmetric encryption algorithm (such as AES) or an asymmetric encryption algorithm (such as RSA) can be used to encrypt the data to generate a unique digital encryption identifier.

[0056] Perform a sign operation on the encrypted request string to generate a digital signature.

[0057] The digital signature is a specific data string obtained by encrypting the request string using a custom private key. Optionally, the private key can be used to sign the summary of the encrypted request string to generate a digital signature. The digital signature can ensure the authenticity and integrity of the request string and prevent the request string from being tampered with during data transmission.

[0058] Generate a transmission request based on the data encryption identifier, digital signature and format of the data to be transmitted.

[0059] Specifically, to generate an HTTP request, the data encryption identifier and digital signature of the request string can be used together as the body part of the HTTP request. At the same time, the appropriate Content-Type and other necessary metadata can be set in the request header, and the HTTPS protocol can be used to transmit the request string, thereby generating an HTTP transmission request and sending it to the backend for processing.

[0060] In some specific embodiments of the present invention, after converting the data to be transmitted into the string format to be transmitted based on the string transmission format, the method further includes:

[0061] Determine whether the format of the string to be transmitted meets the preset packaging conditions.

[0062] Among them, the preset packaging conditions can be specific requirements for processing data into files that are preset. In some specific embodiments, when the data to be transmitted is a large data set, binary data, unstructured data, or data that needs to be stored and archived for a long time, these data cannot be sent directly through the body part of the HTTP request (for example, due to the size limit of the HTTP request or the network bandwidth limit), or generating an HTTP request will cause data corruption or format problems, or it is more appropriate to save these data to be transmitted as files and transmit them through a file transfer protocol (such as FTP, SFTP, HTTP multi-part form data upload, etc.), so it can be determined first whether the data in the string format to be transmitted meets the preset packaging conditions. If it does, the step of packaging the data into a file is entered; if it does not, an HTTP request can be directly generated and sent to the back end.

[0063] If the format of the string to be transmitted meets the preset packaging condition, the format of the string to be transmitted is processed into a request file to be transmitted.

[0064] The request file to be transmitted is a file format obtained by packaging the string format to be transmitted through a dedicated packaging tool. Optionally, if the string format to be transmitted meets the preset packaging conditions, the string format to be transmitted can be packaged into a file for data transmission to ensure the integrity and accuracy of the data. Specifically, the B l ob object and the FileSaver.js library can be used to package the string format to be transmitted into a request file to obtain the request file to be transmitted.

[0065] Send the request file to be transferred to the backend.

[0066] Optionally, the packaged request file to be transferred can be sent to the backend for data transmission. By packaging the data into a file format for transmission, data accuracy loss can be prevented while ensuring data integrity, format correctness and reliability, thereby improving development efficiency.

[0067] In some specific embodiments of the present application, Figure 2 As shown, the data transmission method also includes:

[0068] Step S200, obtaining abnormal information during data transmission.

[0069] Among them, the exception information can be the error information encountered during the data transmission process between the front-end and back-end, and the exception information includes but is not limited to the exception type, exception message, time and location (such as file name, line number) of the exception. In some specific embodiments, the exception handling logic can be added to the front-end and the back-end respectively, such as using a try-catch statement block to capture possible exceptions. When an exception occurs during the data transmission process, the catch statement block can capture the exception and perform corresponding processing (such as retry, rollback, etc.).

[0070] Step S210, classify and process the abnormal information. If the abnormal information is irrecoverable information, proceed to step S220.

[0071] Step S220, returning error information to the front end.

[0072] The unrecoverable information may be abnormal information of unrecoverable data transmission, such as data format error, backend service abnormality, etc. In some specific embodiments, after the abnormal information is captured, it can be classified and processed according to the type and nature of the abnormal information. For unrecoverable abnormalities (such as data format error, backend service abnormality, request abnormality, system resource abnormality, etc.), the corresponding error information should be returned to the front end, and the user should be prompted to perform corresponding processing to improve the reliability and stability of data transmission.

[0073] In some specific embodiments of the present application, Figure 2 As shown, after the abnormal information is classified and processed, it also includes:

[0074] If the abnormal information is recoverable information, go to step S230.

[0075] Step S230, retry the recoverable information until the retry stop condition is triggered, then stop the retry operation and enter step S220, that is, enter the step of returning error information to the front end.

[0076] Among them, recoverable information can be abnormal information such as network timeout, connection interruption, etc. that can restore data transmission. The retry operation is an operation in which the system attempts to retransmit data. The retry stop condition can be a specific requirement for stopping the retry operation set in advance, such as an upper limit on the number of retries, a retry interval limit, an unrecoverable error, etc. In some specific embodiments, if the abnormal information is a network timeout, the system can automatically perform error handling at this time, for example, data transmission can be retried, and a loop structure (such as a while loop) can be used to implement the retry operation. In order to avoid resource waste and performance problems caused by infinite retries, a reasonable upper limit on the number of retries can be set as a retry stop condition. If the number of retries has reached the upper limit, the retry operation needs to be stopped to ensure that the retry operation does not loop indefinitely, thereby avoiding resource waste and performance degradation.

[0077] Optionally, if the retry operation has triggered the retry stop condition, it can be confirmed that the exception information cannot be resolved through automatic processing by the system, and the exception information can be returned to the front end as an error message, and the user is prompted to perform corresponding processing.
