In order to make the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the embodiments of the present invention are further described in detail below with reference to the accompanying drawings. The exemplary embodiments and descriptions of the present invention are provided to explain the present invention, but not to limit the present invention.
First, terms in the embodiments of the present invention are described:

CDS: and the system is matched with the system in the row of the bill exchange, and is responsible for receiving and sending messages of the electronic commercial draft and the business processing of the electronic commercial draft in the row.
As mentioned above, the electronic signature of the client is an encrypted character string with a length of 2000 bits, and the inline CDS system directly receives input data with a length of no more than 1940 through the OTCP platform, so that the communication length between systems cannot meet the requirement of uploading the electronic signature at present. Other schemes for handling very long data are possible, such as using segmented input or directly modifying the length of the input area. The segmented input is to send data for many times and process the data after all the data are received, and the method relates to the integration of messages and the process of interaction for many times, and has complex operation and low efficiency; the problem can be solved by directly increasing the length of the input area, but the OTCP integration platform environment is used, so that platform transformation needs to be involved, the transformation work is huge, and the cost is high. Therefore, no matter segmented input or direct expansion of an input area, the original platform is greatly influenced, large-scale transformation is required, and uncontrollable risks are involved. Therefore, a method is needed to enable the background application to receive data exceeding the OTCP main control input area under the condition of keeping the original flow unchanged, so as to meet the requirement of subsequent application processing.
In order to perform intersystem data transmission and meet the requirement of uploading an electronic signature, an embodiment of the present invention provides an intersystem data transmission method, which, as shown in fig. 1, may include:
and 105, performing intersystem data transmission according to the database main key written in the corresponding position of the input area.
As shown in fig. 1, in the embodiment of the present invention, interface definition information between systems is obtained; intercepting an electronic signature from an input area according to the interface definition information between the systems; storing the electronic signature into a database, and generating a database main key; writing the main key of the database into the corresponding position of the input area according to the interface definition information between the systems; and carrying out data transmission among systems according to the database main key written in the corresponding position of the input area. The embodiment of the invention intercepts the electronic signature from the input area according to the interface definition information between systems, generates a database main key after storing the electronic signature in the database, and then writes the database main key into the corresponding position of the input area; and the data transmission between systems is carried out according to the database main key written into the corresponding position of the input area, so that the called application program can read the stored electronic signature through the database main key, the integrity of data transmission is ensured, and the requirement of transmitting the electronic signature on the system is met.
In the embodiment, inter-system interface definition information is obtained; intercepting an electronic signature from an input area according to the interface definition information between the systems; storing the electronic signature into a database, and generating a database main key; writing the main key of the database into the corresponding position of the input area according to the interface definition information between the systems; and carrying out data transmission among systems according to the database main key written in the corresponding position of the input area.
In this embodiment, the inter-system interface definition information includes: attribute information and primary key rewriting position information of the electronic signature;
intercepting an electronic signature from an input area according to the intersystem interface definition information, comprising: intercepting the electronic signature from an input area according to the attribute information of the electronic signature;
writing the main key of the database into the corresponding position of the input area according to the interface definition information between the systems, which comprises the following steps: and writing the main key of the database into the corresponding position of the input area according to the position information of the main key rewriting position of the electronic signature.
In this embodiment, the attribute information of the electronic signature includes: start position and length information of the electronic signature.
In this embodiment, after storing the electronic signature in the database, generating a database primary key includes:
and after the electronic signature is stored in a local ORACLE database table, converting the electronic signature into a database primary key.
A specific embodiment is given below to illustrate a specific application of the inter-system data transmission in the embodiment of the present invention. In this embodiment, as shown in fig. 2, the inter-system data transmission is performed according to the following steps:
(1) the internet bank generates an electronic signature and other input area information, organizes data according to the definition of the interface and calls a CDS background;
(2) the input data of the online bank is processed by a preprocessing program, and the electronic signature is intercepted and stored in a database table;
(3) writing a main key of a database table into a specified position of a data input area by a preprocessing program;
(4) the platform main control program processes input data and calls a corresponding application program;
(5) the application program reads the electronic signature from the database according to the main key, writes the CDS message and sends the CDS message to the system in the bill exchange line;
fig. 3 is a schematic diagram of an online banking CA signature. Defining the initial position and length of an electronic signature of an interface between systems in interface definition and the position of a primary key of a reverse write-back input area; preprocessing, intercepting the electronic signature from the input area according to the definition of the interface, storing the electronic signature into a database, and generating a main key; writing the generated main key to the corresponding position of the input area according to the interface definition; and the application program called by the OTCP master control uses the primary key to read the electronic signature in the database according to the definition of the interface and carries out subsequent processing.
The embodiment of the invention has three parts, namely a preprocessing part, a data storage part and a platform main control and application part. The three parts respectively complete the work of intercepting, storing and reading data. (1) The preprocessing module intercepts the electronic signature and rewrites the main key generated after the database is stored into the position corresponding to the input area; (2) the data storage module stores data into a designated table and generates a primary key; (3) and the platform main control and application module finds the main key according to the definition of the interface and the appointed position of the interface if the transaction of the electronic signature is related, and then reads the electronic signature according to the main key for subsequent processing.
Aiming at the problem that the length which can be processed by the OTCP platform main control program is limited, the embodiment of the invention adds a preprocessing before the original OTCP platform main control processing program according to the principle of minimum influence, better expansibility and minimum cost on the whole product system, and has the main function of intercepting an electronic signature appointed by an interface, then storing the electronic signature into a database, and reversely writing a main key of the data into a data input area, wherein the length of the main key is far smaller than that of the electronic signature, so that the length of the input area can be ensured to be within the processing range of the OTCP platform main control program, and after the platform main control, an invoked application program can use the main key to read the electronic signature from the database for subsequent processing. Based on AIX operating system, small computer CICS environment, ORACLE database and COBOL programming language, the electronic signature is stored by using database technology, thereby reducing the data length of the input area, meeting the processing requirement of OTCP platform main control program and solving the limitation of the data length between systems. For the CDS system, the online bank is only one of a plurality of channels, so if the initiating channel can be distinguished before calling, the preprocessing mode can be only used for the online bank channel, and the processing efficiency is improved.
The embodiment of the invention solves the problem by considering the principle of minimum influence and minimum cost, uses additional database storage for data with the length exceeding the length, and transmits the acquired and stored primary key to the final application program. This achieves a reduction in the length of the input data area, and the application program can also obtain the target data while using the data. The length and the position of the electronic signature are specified in the interface and are placed at the end of the interface data area, so that the preprocessing program can be positioned more conveniently, and the expansibility of the method is better. If the length of the input area of the OTCP platform is directly adjusted, the method relates to a large amount of transformation inside the whole OTCP platform and the test applied on the existing platform, has high cost and wide transaction range. By means of the database storage mode, the data exceeding the fixed length is stored, and the stored main key is rewritten to the data area, so that the purpose of reducing the length of the input area is achieved. Preprocessing, intercepting ultralong data, writing the ultralong data into a database table, and then writing the corresponding primary key back to the data area; when the specific application logic needs to use the ultra-long data, the target data is acquired in the database table through the primary key through the defined interface. The invention is based on the solution of the problem of the data transmission length between systems, when the system requirements cannot be met or huge risks are brought by changing the length, the data are converted, the database table is used for storing overlong data, and when the data need to be used in the application, the data are acquired in the database through the written-back main key, so that the consistency of the whole process and the integrity of the data are realized. The invention has the advantages of low cost and small influence on the original system.
