Examples
The present invention will be described in detail with reference to a specific embodiment, but it should be noted that the specific embodiment is only for better describing the present invention and should not be construed as limiting the present invention.
Step S101: receiving a service request of a user, and acquiring a request message of the service request, wherein the request message comprises a message header and application data.
Specifically, the service terminal and the mobile terminal communicate in a connection-oriented Socket mode based on a TCP/IP protocol. The mobile terminal is the initiator of each communication interaction, and the service terminal responds to the service request of each accessed mobile terminal. According to the user input information and the service operation, and after the user confirmation, the mobile terminal sends a service request to the service terminal. The data packet organization adopts an ISO8583 packet protocol, and the data packet structure can be represented by the following table 1, where the data packet structure is: "message length + TPDU (protocol format) + message header + application data", wherein: the "packet length" indicates the total packet length. In one embodiment of the present invention, the total length of the header is 12 bytes, and the header is compressed by BCD code to be expressed as a value with a length of 6 bytes. "TPDU (transport protocol data unit)" includes ID, destination address, source address; the "header" includes: application type, software version number, terminal state, processing requirement, reserved field and the like; the "application data" includes: ISO8583Msg, transaction data, data element definitions, etc.
TABLE 1
In the process of sending the request message, when the application program of the mobile terminal is packed and sent, the parameters such as the application type, the software version number, the terminal state and the like in the data message are filled according to the relevant self-defined information of the mobile terminal, so that the service terminal can correspondingly process the service request according to the filled value after receiving the service request.
For example: the "application category" can be "customized" as:
the financial payment application is as follows: 60. the value added service payment is as follows: 62. the number aggregation universal service is as follows: 61
The "software version number" can be customized as:
initial version: 21. the starting date: 23
The "terminal state" can be customized as:
normal transaction state: 0. and (3) testing the transaction state: 1
The "processing requirements" can be customized as: no processing requirement: 0. reprocessing 1
It should be noted that, in the response message returned by the service terminal, the service terminal fills in the "processing requirement", other parameters keep the original value and return, and the mobile terminal performs corresponding processing according to the processing requirement in the message header of the received return message.
Step S102: and analyzing the request message, confirming the service type of the service request, and acquiring a data domain list of the application data according to the service type.
Specifically, a "data field list" in the application data corresponding to the "application type" is acquired according to the parameter of the "application type" in the header of the request packet.
For example, the different applications correspond to the following data field list, and a sample table of the data field list may be as shown in table 2:
the data field with the service type of financial payment application is as follows: MCE
The data field for payment of value added service type is as follows: MCO
The data domain of the service type of the aggregation universal service is as follows: MO (metal oxide semiconductor)
TABLE 2
Step S103: analyzing the data domain list to obtain basic data in the data domain; wherein the basic data of the data field comprises: message type, transaction type, data element; in an embodiment of the present invention, the length of the message type of the data field is 4 bytes, which is used to define the message type; the length of the service data is 16 bytes, and the service data is used for defining different service classes; the data elements are of indefinite length bytes in length and contain the actual data of the data field.
Specifically, if the data field list includes an encrypted field, the data related to the service in the encrypted field that needs to be encrypted is obtained after decryption by the specified key. The encrypted data can adopt an Aes encryption algorithm or a Des encryption algorithm, and the plaintext data can be obtained after decryption by using a specified key.
Step S104: according to the service type, assembling the basic data according to a preset sequence to obtain complete service data;
step S105: and processing the complete service data according to service logic to generate service feedback information, packaging the service feedback information according to the data domain list corresponding to the service type and the preset sequence, and sending the feedback information to the mobile terminal.
For example, the following steps are carried out:
taking user consumption as an example, when the current user consumes 100 yuan, the mobile terminal uploads user consumption data to the service terminal. After the service terminal verifies the message, 100 yuan is subtracted from the balance (1000 yuan) of the user, and balance information (900 yuan) is fed back to the mobile terminal. In this process, the following message data are involved:
1. request message sent up
Message header:
the application categories are: 60 (for financial payment applications)
Software version number: 2123 (initial version 21 start date 23)
The terminal state: 0 (Normal transaction state)
The treatment requirements are as follows: 2 (transaction report)
Since the application category in the basic data of the packet is 60, the application category is defined as: the financial payment application is made by agency, and the preset sequence of the application data corresponding to the application is as follows:
MCE, namely: mandatory domain + conditional domain + encrypted domain,
wherein, the mandatory domain: message type: 0320, representing a transaction request;
condition field: 20160501000000, indicating a transaction send time condition;
encryption domain: user name, account number, password, amount and the like (encrypted by AES).
2. Business logic for processing data by service terminal
After the uploaded request message is correctly analyzed, the background service terminal performs data processing according to the following service logic:
(1) acquiring user information according to the account;
(2) verifying the legality of the user name and the password, entering the next step if the user name and the password pass the legality, and otherwise, reflecting the abnormity;
(3) verifying whether the current user balance is larger than the uploaded consumption amount, if the current user balance is verified to be passed, carrying out the next step, and if not, reacting abnormally;
(4) and subtracting the consumption amount from the balance, repeating the remaining amount, and returning the remaining amount data.
3. Packaging the message and sending the feedback information to the mobile terminal
Wherein the feedback information includes: the application data and the header of the message,
the application data includes:
(1) encrypting the user name, the account number, the password and the residual amount data by adopting AES encryption, and taking the encrypted data as an encryption domain;
(2) 20160501000011 (transaction processing completion time) as a time condition field;
(3) 0330 (transaction result return) message type as mandatory field;
(4) the application data is composed of a mandatory domain, a conditional domain and an encryption domain, and the application data comprises the following components in a preset sequence: the MCE, i.e., the mandatory domain + the conditional domain + the encrypted domain, is arranged in that order.
(II) the return message header comprises:
the application categories are: 60 (for financial payment applications)
Software version number: 2123 (initial version 21 start date 23)
The terminal state: 0 (Normal transaction state)
The treatment requirements are as follows: 3 (return transaction result).
And finally, the mobile terminal receives and analyzes the feedback information returned by the service terminal to obtain a return message of the feedback information.
If the return message is a transaction result message, analyzing the transaction result message and displaying a transaction result;
if the return message is a write command message, the write command is sent to the SQLITE database one by one, the operation result is sent to the service terminal in a data message mode, and the feedback information returned by the service terminal is continuously waited;
if the 'transaction state is abnormal' (the reason may be that no APDU response is received, the message reception of the service terminal is overtime or other reasons), the mobile terminal may send a transaction retry request message to the service terminal for the transaction supporting the retry mechanism, so as to continue the transaction.
