Description

Technical Field

[0001] The present invention relates to the field of communication technology, and more particularly to a data transmission method, device and computer-readable medium. Background Art

[0002] Data transmission is the communication process of transferring data from one place to another. Data types include structured data and unstructured data. Structured data is used to indicate data managed in the form of relational databases, which is usually small-capacity data; unstructured data is used to indicate data with irregular or incomplete data structure, no predefined data model, and data that is not convenient to be represented by a two-dimensional database logical table. It is usually large-capacity data, such as videos, PDF files, or various forms of pictures. However, in actual applications, the data transmitted is not necessarily a single type of data, and many types of data are often transmitted together.

[0003] In the prior art, there are protocols for data transmission such as Http protocol and FTP protocol. Using Http protocol for data transmission has the following advantages: first, Http protocol is an application layer protocol based on TCP protocol, so it can achieve reliable transmission; second, Http protocol is a request-response protocol, the client sends a request and the server returns a response, thus improving the timeliness of data transmission.

[0004] The working principle of the FTP protocol is that the FTP client connects to the FTP server and provides a username and password for authentication. After the authentication is passed, the client can browse files on the server and perform some interactive operations; thereby improving the security of data transmission.

[0005] In the process of implementing the technical solution in the embodiment of the present application, the inventor of the present application found that the above technology has at least the following technical problems: 1. For unstructured data, if the Http protocol is used for transmission, data transmission loss may occur. This is mainly due to the large capacity of unstructured data, which causes a large amount of online resources to be occupied during the data transmission process, resulting in data transmission jams, and then causing part of the transmitted data to be lost; in addition, data transmission jams will also cause the problem of low data transmission efficiency. 2. For structured data, if the FTP protocol is used for transmission, there may be problems of low transmission efficiency and high data load processing at the data receiving end; this is mainly because the FTP protocol does not make any records of the transmitted data, and when the receiving end receives the structured data, it needs to analyze and process the status of the structured data, which complicates the data processing process at the data receiving end, thereby reducing the timeliness of data transmission. Summary of the invention

[0022] In order to make the purpose, features and advantages of the present invention more obvious and easy to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0023] Structured data can be transmitted through the HTTP protocol because of its small data capacity, fast transmission speed and good time limit; unstructured data can be transmitted through the FTP protocol

[0024] During data transmission, multiple types of data are usually transmitted together; in order to enable efficient data transmission; the inventor of the present application proposed to embed unstructured data in structured data by means of storage addresses, and then transmit the structured data from the second application to the first application based on the Http transmission method; thereafter, the first application parses the structured data and obtains the storage address corresponding to the unstructured data from the parsed result, and finally the first application obtains the structured data from the third party corresponding to the storage address; thereby, not only the real-time transmission of structured data is realized, but also the reliability of unstructured data transmission is improved, and the problem of poor timeliness or reliability caused by the simultaneous transmission of structured data and unstructured data using the same transmission protocol in the prior art is solved, thereby improving the efficiency of structured data and unstructured data transmission.

[0025] like Figure 1 FIG. 1 is a flow chart of a data transmission method provided by an embodiment of the present invention.

[0026] A data transmission method includes a first application and a second application; the method is applied to the first application and includes at least the following steps:

[0027] S101, receiving structured data sent by a second application through an Http interface;

[0028] S102, parsing the structured data to obtain a parsed file;

[0029] S103, obtaining the storage address of the unstructured data from the parsed file;

[0030] S104, obtaining unstructured data from a third party corresponding to the storage address through an FTP interface.

[0031] Here, the first application and the second application may correspond to different servers, or may be different applications integrated in the same server. The first application is communicated with the second application and the third party respectively.

[0032] In S101, the storage address of the unstructured data is embedded in the structured data. In other words, the structured data is formed by the first structured data representing a specific meaning and the second structured data corresponding to the storage address representing the unstructured data.

[0033] In order to effectively embed unstructured data into structured data, the structured data is transmitted in XML format, so that the storage address of unstructured data can be defined in the XML file, which is beneficial to the later parsing of structured data and improves the efficiency of data processing by the first application.

[0034] The second application sends structured data in XML format to the first application through the Http interface; the first application receives the structured data sent by the second application through the Http interface.

[0035] In S102 , before parsing the structured data, the storage address of the unstructured data is invisible to the first application or the second application.

[0036] The first application parses the structured data based on preset rules or a trained model and outputs a parsed file.

[0037] In S103, semantic recognition is performed on the parsed file to obtain the storage address of the unstructured data; or the parsed file is segmented based on preset fields to output the storage address of the unstructured data.

[0038] In S104, the first application sends an unstructured data request to a third party corresponding to the storage address, and the third party sends unstructured data corresponding to the unstructured data request to the first application. The third party may be a cloud platform or a file storage server.

[0039] This embodiment can quickly acquire structured data based on the real-time nature of Http transmission, and after parsing the structured data, completely acquire unstructured data from a third party corresponding to the unstructured data storage address through FTP transmission, thereby improving the reliability of unstructured data transmission; thereby, structured data and unstructured data can be efficiently transmitted.

[0040] In order to avoid uncontrollable factors in the data transmission process, this embodiment adopts a retransmission mechanism combined with a result notification method to improve the reliability of unstructured data transmission. In a preferred implementation of this embodiment, the method also includes: monitoring the acquisition status of the unstructured data; if the monitoring result indicates that the acquisition status is acquired, storing the acquired unstructured data in a local database; if the monitoring result indicates that the acquisition status is not acquired, re-executing the acquisition operation according to a preset time; and counting the number of acquisition operations until the number reaches a preset threshold and the acquisition operation is not performed, generating acquisition failure information, and sending the acquisition failure information to the administrator.

[0041] Here, no matter whether the first application obtains the unstructured data through administrator intervention or based on the retransmission mechanism, the first application marks the acquisition status as acquired. When the first application detects the acquired status, the acquired unstructured data is stored in the local database.

[0042] In order to avoid the inability to save data due to database failure, this embodiment adopts a retransmission mechanism combined with a result notification method, which can ensure the effective storage of the parsed file, thereby improving the reliability of data transmission. In a preferred implementation of this embodiment, the method also includes: performing a local storage operation on the parsed file; if the result of the local storage operation indicates that the parsed file is stored in the local database, storing the structured data in a backup directory; if the result of the local storage operation indicates that the parsed file is not stored in the local database, re-performing a local storage operation on the parsed file; and counting the number of local storage operations; until the number reaches a preset threshold and the local storage operation is not performed, the storage failure information is sent to the administrator.

[0043] Here, no matter through administrator intervention or based on the retransmission mechanism, the first application performs a local storage operation on the parsed file; when the first application detects that the parsed file is stored in the local database, the structured data in XML format is stored in the backup directory.

[0044] In order to avoid uncontrollable factors that occur during data transmission, this embodiment adopts a retransmission mechanism combined with a result notification method to improve the reliability of unstructured data transmission. In a preferred implementation of this embodiment, the method also includes: performing a feedback operation on the second application; the feedback operation includes feedback on successful reception of unstructured data and / or feedback on successful reception of structured data; if the feedback operation result indicates that there is no feedback, re-performing the feedback operation at a preset time; and counting the number of feedback operations; if the feedback operation is not performed when the number reaches a preset threshold, the feedback failure information is sent to the administrator.

[0045] Here, no matter through administrator intervention or based on a retransmission mechanism, the first application receives the feedback result of the second application.

[0046] In order to improve the security of unstructured data transmission, in a preferred implementation manner of the present embodiment, before obtaining the unstructured data from the third party corresponding to the storage address through the FTP interface, it also includes: sending user identity information to the third party corresponding to the storage address so that the third party can verify the user identity information of the first application; if the verification is successful, sending an unstructured data request to the third party through the FTP interface.

[0047] For example: the first application sends user identity information to a third party corresponding to the storage address; the third party verifies the user identity information of the first application and sends the verification result to the first application; the first application sends an unstructured data request to the third party; the third party sends the unstructured data corresponding to the unstructured data request to the first application.

[0053] S204, the first application receives unstructured data corresponding to the unstructured data request from a third party through an FTP interface;

[0056] The case information as structured data includes basic case information and the storage address of legal documents; the second application sends the case information in XML format to the first application; the first application parses the case information to obtain the basic case information and the storage address of the legal document; in order to obtain the legal document, the first application needs to obtain the PDF file corresponding to the legal document from the third party specified by the storage address; thereby, the transmission of structured data and unstructured data between the two applications is realized; so that the first application can obtain the basic case information and legal documents corresponding to the case information.

[0057] A data transmission method includes a first application and a second application; and includes at least the following steps:

[0058] S1, the second application sends structured data in XML format to the first application through the Http interface.

[0061] S4, the first application performs a local storage operation on the parsed file; if the result of the local storage operation indicates that the parsed file is stored in the first area of ​​the local database, the structured data is stored in the local backup directory; if the result of the local storage operation indicates that the parsed file is not stored in the first area of ​​the local database, the local storage operation is re-executed on the parsed file; and the number of local storage operations is counted; if the local storage operation is not performed until the number reaches a preset threshold, the storage failure information is sent to the administrator so that the administrator can re-execute the local storage operation after repairing the fault.

[0062] S5, the first application obtains the storage address of the unstructured data from the parsed file; and sends the user identity information to the third party corresponding to the storage address so that the third party can verify the user identity information of the first application; if the verification is successful, the first application sends an unstructured data request to the third party corresponding to the storage address through the FTP interface.

[0063] S6, the first application obtains the unstructured data corresponding to the unstructured data request from the third party through the FTP interface; and monitors the acquisition status; if the monitoring result indicates that the acquisition status is acquired, the acquired unstructured data is stored in the second area of ​​the local database; if the monitoring result indicates that the acquisition status is not acquired, the acquisition operation is re-executed according to the preset time; and the number of acquisition operations is counted, until the number reaches a preset threshold and the acquisition operation is not performed, then an acquisition failure message is generated, and the acquisition failure message is sent to the administrator so that the administrator can re-execute the acquisition operation after repairing the fault.

[0064] S7, the first application feeds back a feedback result of successfully acquiring the unstructured data to the second application through the Http interface.

[0065] This embodiment combines the real-time nature of Http transmission and the reliability of FTP transmission to ensure the efficiency and security of data transmission to the greatest extent; and in view of the uncontrollable factors that may occur during the data transmission process and the storage process after file parsing, a retransmission mechanism is adopted to ensure the success rate of data transmission, thereby further improving the reliability of data transmission.
