Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of Internet, and particularly relates to an online payment method and device based on WeChat payment suitable for a conference system. BACKGROUND

[0002] As an important platform for business communication, the conference system is a key link to ensure the smooth progress of the conference, which involves the collection of conference fees, financial management and settlement and other aspects. An effective conference payment system can ensure the timely, accurate and secure processing of conference fees, which is crucial for improving conference organization efficiency and participant experience. However, the traditional payment method has been unable to meet the needs of modern conferences, and conference participants need a quick and secure payment method to handle conference fees. The existing conference payment methods such as cash settlement, bank transfer, credit card payment and the like have serious shortcomings. For example, the limitation of cash settlement is that the payment amount is limited and cannot meet the demand of large payment, and the limitation of bank transfer is that although it is safe, the transfer time is long, which is not conducive to immediate settlement, and when it involves cross-border transactions, it may generate additional handling fees and exchange rate losses, and it also involves complex financial management and accounting, and there is a problem of fund occupation, which is not flexible for small or temporary organized conferences. In short, the existing conference payment methods have great limitations in convenience, security, cost and scope of application. Therefore, new payment solutions are needed, such as payment methods based on mobile payment platforms, which are of great significance for improving conference payment efficiency and user experience.

DETAILED DESCRIPTION

[0045] The present application will be described in detail below according to the drawings and preferred embodiments, and the purposes and effects of the present application will become more apparent. The present application will be further described in detail below in combination with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and do not limit the present application.

[0046] As shown in Figure 1 , an online payment method based on WeChat payment suitable for a conference system specifically includes the following steps:

[0047] S001: A user (usually a conference participant) fills in the registration information and selects the registration fee related information. The user registration information includes name, contact information, email, participant identity, affiliated unit or school, invoice information, etc. The registration fee related information includes conference registration fee, hotel accommodation, catering, etc.

[0048] S002: The conference payment system calculates the total required fee according to the registration fee related information, saves the corresponding registration information in the database, and finally displays the total fee to the user.

[0049] S003: The user selects to start payment and sends a payment request to the conference payment system.

[0050] S004: The conference payment system checks whether there is a valid registration order for the user, and if so, performs S005 for pre-checking; if not, it jumps to perform S007.

[0051] The registration order includes: registration order ID (unique identifier), associated user ID, associated payment order ID (payment order unique identifier), registration order status (including "successful", "unpaid", "canceled" three states, where "canceled" indicates that the registration order is invalid), total order amount, expiration time.

[0052] Among them, the payment order is generated according to the registration order and is associated with it. The information of the payment order includes: payment order ID (unique identifier), associated registration order ID (registration order unique identifier), WeChat prepayment transaction link, payment completion time, payment order status (including "paid", "unpaid", "closed" three states), total order amount, payer information, payment scenario description, payment description of goods (i.e. the description of the registration and competition fee of the conference), expiration time.

[0053] S005: Pre-checking the existing registration order to avoid duplicate payment, which is implemented through the following sub-steps:

[0054] (S5.1) Determine whether the state of the existing registration order is "successful", if so, jump to perform (S5.5), otherwise perform (S5.2).

[0055] (S5.2) Since the existing registration order corresponds to a valid payment order, and on the conference payment system side, the states of the registration order and the payment order are kept consistent by using database transactions, for example, when the payment is successful, the payment order state is updated to "paid" at the same time The registration order state is also updated to "successful", so the state of the payment order at this time cannot be "paid", but only in the "unpaid" or "closed" state. However, since the result of the WeChat payment platform notifying the merchant system (here, the conference payment system) of the successful payment is asynchronous, the payment status may not be consistent between the WeChat payment platform and the conference payment system side, so the intermediate state is difficult to confirm, and therefore it is necessary to further confirm whether the state of the payment order is unpaid, if so, perform (S5.3); if not, it means that the state of the payment order is "closed", and directly jump to perform S006.

[0056] (S5.3) Remote (WeChat payment platform) to local (conference payment system) payment state synchronization. Since the WeChat payment platform will asynchronously notify the merchant system (here is the conference payment system) of the payment success result, there is a synchronization lag between the payment order state of the conference payment system and the prepayment transaction state of the WeChat payment platform, which cannot always be consistent. Therefore, when (S5.2) judges that the state of the payment order is not paid, the conference payment system needs to actively pull the payment state information of the prepayment transaction from the WeChat payment platform once (i.e. to perform a payment state synchronization), and then update it to the conference payment system.

[0057] (S5.4) Confirm whether the state of the payment order is paid, if paid, execute (S5.5), if not paid, end the pre-check and jump to S006.

[0058] (S5.5) Remind the user that the payment has been completed and does not need to be repeated, and end the payment process.

[0059] S006: Close the existing payment order, cancel the existing registration order, and release the occupied hotel inventory. Specifically:

[0060] Call the open general close order interface provided by the WeChat payment platform to close the prepayment transaction associated with the existing registration order, update the corresponding payment order state to closed, and update the state of the existing registration order to canceled, and then release the hotel inventory occupied by the registration order. Here, in a distributed high-concurrency scenario, a distributed lock also needs to be added to prevent data inconsistency. At the same time, a database transaction needs to be added to keep the related database operations atomic, consistent, and isolated.

[0061] S007: Generate a new registration order and lock the user registration information. Specifically:

[0062] Generate a new registration order, add an expiration time to the registration order, for example, 30 minutes, and associate it with the user registration information, and lock the user registration information for the expiration time, during which the user is not allowed to modify the registration information. After the expiration time, the registration order state is ready to be updated to "canceled".

[0063] And there are two ways to unlock the corresponding registration information: the first is that the user actively cancels the registration order, and as soon as the registration order is canceled, the user registration information is unlocked, and after unlocking, the user can modify the registration information; The second is to start a timed CronJob (task) to check the expired registration orders in the database, and then the system automatically cancels these expired registration orders. However, the implementation logic of the two ways to cancel the registration order is consistent, and the steps are as follows:

[0064] (1) Release the hotel room type inventory occupied by the registration order.

[0065] (2) Update the status of the registration order to "Cancelled".

[0066] (3) Update the status of the payment order corresponding to the registration order to "Closed", and directly call the open and general close order interface provided by the WeChat payment platform to close the prepayment transaction order associated with the payment order.

[0067] S008: The hotel room type selected by the user is deducted from the inventory. The hotel room type arranged for each conference is limited by the inventory, so the corresponding hotel room type selected by the user is subjected to a deduction operation.

[0068] S009: Generate a payment order and call the order interface of the WeChat payment platform. Specifically:

[0069] According to the registration order, a payment order is generated, the payment order and the registration order are associated, and then the WeChat payment platform provides an open and general order interface according to the payment order.

[0070] S010: The order interface of the WeChat payment platform generates a prepayment transaction, returns the prepayment transaction link to the merchant system, and the conference payment system saves the prepayment transaction link in the payment order information. The ID (unique identifier) of the payment order corresponds to TradeNo in the prepayment transaction of the WeChat payment platform, which is used to uniquely identify an order on the WeChat payment platform side.

[0071] S011: The conference payment system generates a payment QR code according to the prepayment transaction link, and then displays the payment QR code picture to the user. The payment QR code corresponding to the payment order also has a validity time, and the user needs to complete the payment within the specified validity time. Once the payment QR code is invalid, the user needs to refresh the payment QR code to pay again, and the conference payment system will generate a new payment QR code and display it to the user.

[0072] S012: The user opens the WeChat client and uses the scan function to submit the prepayment transaction link. Specifically, the user opens the mobile WeChat client, uses the WeChat scan function, scans out the prepayment transaction link, and submits it to the WeChat payment platform.

[0073] S013: The WeChat payment platform verifies the validity of the prepayment transaction link and returns the user for payment authorization.

[0074] S014: The user confirms the payment, inputs the WeChat payment password, and submits the payment authorization to the WeChat payment platform.

[0075] S015: The WeChat payment platform verifies the payment authorization, completes the payment transaction, and asynchronously notifies the merchant system of the payment result.

[0076] S016: The conference payment system processes asynchronous callback of the WeChat payment platform, and updates the local payment state. Specifically, the conference payment system processes asynchronous callback of the WeChat payment platform, and updates the local payment state.

[0077] After the conference payment system receives the result of successful payment, the payment state is synchronized to the payment order on the conference payment system side, and the state of the user's registration order is modified to payment success. The user's registration information is permanently locked and cannot be modified, that is, the conference registration is successful.

[0078] S017: The user is shown that the registration and payment are successful, and the conference registration is successful.

[0079] In order to realize the online payment method based on the WeChat payment suitable for the conference system, the embodiment of the application also provides an online payment device based on the WeChat payment suitable for the conference system, as shown in the accompanying drawings, the device comprises: a registration and online payment page rendering module 100, a conference online payment module 200, a WeChat client 300, a WeChat payment platform 400, and a database 500. The registration and online payment page rendering module 100, the conference online payment module 200, and the database 500 belong to the conference payment system. Figure 2

[0080] The registration and online payment page rendering module 100 is used for front-end page rendering of user registration and conference, and provides an interactive operation interface for user registration and online payment, and does not include business data flow storage and processing logic.

[0081] The conference online payment module 200 is used for providing online payment of conference fees related business, and comprises: a conference registration information management module 201, a conference online payment submodule 202, a WeChat payment platform asynchronous callback processing submodule 203, and a timing CronJob submodule 204.

[0082] The conference registration information management module 201 is used for managing user registration information, and the user fills in and submits the registration information and selects registration fee related information. The registration information and the registration fee related information can be modified in an unlocked state.

[0083] The conference online payment module 202 is used for processing online payment application of the user, generating a registration order and a payment order, locking the user registration information, then interacting with the WeChat payment platform, the WeChat payment platform generating a prepayment transaction link, returning to the conference payment system, and finally generating a payment two-dimensional code according to the prepayment transaction link and returning to the user for scanning code payment.

[0084] ​The WeChat payment platform asynchronous callback processing module 203 is configured to process the asynchronous notification of whether the payment is completed fed back by the WeChat payment platform. After the user completes the payment by scanning the code, the WeChat payment platform will asynchronously push the payment completion result to the conference payment system, and the WeChat payment platform pushes the result according to the callback address of the conference payment system configured when the pre-payment transaction link is generated.

[0085] The timing CronJob submodule 204 is configured to process the invalid registration order in a timing manner. When the user requests online payment, the registration order is generated, the registration order has an invalid time, and the user's participation registration information is locked (the user is not allowed to modify the registration information), so the registration order exceeding the valid time needs to be processed in a timing manner. The processing logic is that a CronJob is started in the background to scan the expired registration order in a timing manner, the invalid registration order is processed one by one, the registration order state is updated to "canceled", the payment order associated with the registration order is processed, the hotel room type inventory occupied by the registration order is released, and finally the user's registration information is updated from the locked state to the unlocked state.

[0086] The WeChat client 300 is configured to be used for the user to scan the code to pay the conference fee.

[0087] The WeChat payment platform 400 is configured to realize the core logic of the WeChat payment, to interact with the conference payment system, to complete the generation of the pre-payment transaction link, the pre-payment transaction closing, the WeChat payment result asynchronous notification of the merchant system, the verification of the WeChat user authorization to complete the payment, and the like.

[0088] The database 500 is configured to store the data generated by the conference participation registration and online payment, for example, to store the user registration information, the registration order information, the payment order information, and the like.

[0089] Further, the data communication between the registration participation and online payment page rendering module 100 and the conference online payment module 200, between the conference online payment module 200 and the WeChat payment platform 400, and between the WeChat client 300 and the WeChat payment platform 400 is in the form of HTTPS. Because HTTPS uses the SSL / TLS protocol to encrypt data, the security of the data in the network transmission process is ensured, which means that the communication between the user and the server is encrypted, and a third party cannot easily intercept and read the data, and the use of HTTPS can prevent user data (such as login credentials, personal information, and transaction data) from being stolen by a man-in-the-middle attacker. This is particularly important for e-commerce websites, online banking services, and any website that requires users to input sensitive information. Therefore, the conference payment system of the present application provides a secure online payment environment by using HTTPS.

[0090] The application integrates the WeChat payment into the conference system, can greatly facilitate Chinese users, and also widens market coverage of the conference system, improves user experience and conference organization efficiency.

[0091] Those skilled in the art can understand that the above description is only preferred examples of the application and is not used to limit the application, although the application is described in detail with reference to the foregoing examples, those skilled in the art can still modify the technical solutions recorded in the foregoing examples or make equivalent replacement for part of the technical features. Any modification, equivalent replacement, etc. made within the spirit and principle of the application shall be included in the protection scope of the application.
