Example one
Fig. 1 is a flowchart of a transaction issuing method according to an embodiment of the present invention, where the present embodiment is applicable to a case of issuing a transaction to a server, and the method may be executed by a transaction issuing device according to an embodiment of the present invention, where the transaction issuing device may be implemented in a software and/or hardware manner, and the transaction issuing device may be integrated in the server. As shown in fig. 1, the method specifically includes the following steps:
s110, acquiring a transaction file, wherein the transaction file comprises: transaction document information and transaction dependent document inventory.
The transaction file is a file formed by transaction related information, and comprises: the transaction file information and the transaction dependence file list can also comprise transaction data; the transaction file information may include information such as the name of the transaction file, the index serial number, and the storage path. When opening a transaction, it is often necessary to rely on one or more profiles, i.e. transaction dependent files. The transaction dependent file manifest is a list of transaction dependent files required for recording transaction files.
For example, the transaction file may be obtained by the server receiving, through the user interface, the transaction file information and the transaction dependent file list uploaded by the user. The transaction file may be a json formatted file.
S120, determining a first target hash value of the transaction file based on the message digest algorithm.
The message digest algorithm is also called as a hash algorithm or a hash algorithm, and is characterized in that a secret key is not needed in the encryption process, encrypted data cannot be decrypted, and the same ciphertext can be obtained only by inputting the identical plaintext data and passing through the identical message digest algorithm, so that the information transmission is complete and consistent. Commonly used message digest algorithms may include: MD5(Message Digest Algorithm 5).
Illustratively, the first target hash value of the transaction file determined by the message digest algorithm is a unique 128-bit binary hash value, and may also be converted into a 32-bit string in hexadecimal.
And S130, if the transaction file is not contained in the server-side database, storing the transaction file information and the second target hash value of the transaction file in the server-side database.
The system comprises a server and a client, wherein the server is provided with a database for storing transaction files, the process of storing the transaction files in the server database is called a transaction release process, and the transaction files are released in the server database and can be obtained by the client for establishing communication with the server.
Specifically, whether the transaction file is contained in the server-side database is judged, and if the transaction file is not contained in the server-side database, the transaction file information and the first target hash value of the transaction file are stored in the server-side database, so that the transaction issuing process is realized.
In the embodiment of the invention, by acquiring the transaction file, the transaction file comprises the following components: transaction document information and a transaction dependent document list; determining a first target hash value of a transaction file based on a message digest algorithm; if the transaction file is not contained in the server-side database, the transaction file information and the first target hash value of the transaction file are stored in the server-side database, so that the redundancy rate of transaction release can be reduced, the consumption of network bandwidth, storage space and transaction time is reduced, the transaction release efficiency is improved, and the user experience is improved.

and if not, updating the transaction file of the server based on the transaction file and the first target hash value.
The server transaction file refers to a transaction file already contained in a server database, and the hash value of the server transaction file is a hash value obtained by calculating the transaction file stored in the server based on the same information digest algorithm as the first target hash value.
And judging whether the first target hash value is the same as the hash value of the server transaction file or not by comparing the first target hash value of the transaction file with the hash value of the server transaction file contained in the server database. If the transaction data is different from the name or the index serial number, the transaction data in the transaction file is changed, so that the hash value of the transaction file is changed. Therefore, the server transaction file needs to be updated based on the transaction file and the first target hash value. The updating process may be considered as replacing the server transaction file with the transaction file, replacing the hash value of the server transaction file based on the first target hash value. If the transaction data are the same, the transaction file with the completely same transaction data is stored in the server-side database, repeated issuing is not needed, incremental issuing transaction is achieved, and compared with full-amount issuing transaction, redundancy of transaction issuing can be reduced, consumption of network bandwidth, storage space and transaction time is reduced, transaction issuing efficiency is improved, and user experience is improved.
Optionally, determining that the transaction file is not contained in the server-side database includes:
analyzing the identification information in the transaction file information, wherein the identification information comprises: a file name or file identification number;
and if the transaction file is not inquired in the server-side database based on the identification information, determining that the transaction file is not contained in the server-side database.
Wherein, the trade file information contains identification information, and the identification information includes: file name or file identification number.
Specifically, the information of the transaction file is analyzed to extract the identification information, each transaction file stored in the server database is queried according to the identification information, and whether the transaction file is contained in the server database is determined according to the query result of the identification information. And if the transaction file is not inquired in the server-side database based on the identification information, determining that the transaction file is not contained in the server-side database. Otherwise, if the transaction file is inquired in the server-side database based on the identification information, the transaction file is determined to be contained in the server-side database.

Wherein, the transaction dependent file to be downloaded can be stored in the server in advance.
And S230, updating the client transaction file in the client database according to the transaction dependence file.
Specifically, the client transaction file in the client database is updated incrementally according to the downloaded transaction dependency file. The transaction dependent file is updated incrementally, so that redundancy of transaction update can be reduced.
According to the technical scheme of the embodiment, the transaction file is acquired and comprises the following steps: transaction document information and a transaction dependent document list; if the transaction dependent file in the transaction dependent file list is not contained in the client transaction file, downloading the transaction dependent file, wherein the client transaction file is a transaction file corresponding to the transaction file information contained in the client database; the client transaction files in the client database are updated according to the transaction dependency files, so that the redundancy of transaction updating can be reduced, the consumption of network bandwidth, storage space and transaction time is reduced, the transaction updating efficiency is improved, and the user experience is improved.

Commonly used message digest algorithms may include: MD5(Message Digest Algorithm 5).
Illustratively, the second target hash value of the transaction file determined by the message digest algorithm is a unique 128-bit binary hash value, and may also be converted into a 32-bit string in hexadecimal.
Specifically, the second target hash value is compared with the hash value of the transaction dependent file in the client database, and if the second target hash value is different from the hash value of the transaction dependent file in the client database, it indicates that the transaction dependent file is not included in the client database. Otherwise, the transaction dependent file is indicated to be contained in the client database.
