One embodiment of the present specification provides a resource processing method based on distributed transactions, a resource processing apparatus based on distributed transactions, a resource processing system based on distributed transactions, a computing device, and a computer-readable storage medium. The following detailed description and the explanation of the steps of the method are individually made with reference to the drawings of the embodiments provided in the present specification.

An embodiment of a resource processing method based on distributed transactions provided in this specification is as follows:

referring to fig. 1, it shows a flow chart of a distributed transaction-based resource processing method provided in this embodiment.

Step S102, a resource pledge request submitted by a user is obtained.

In practical application, in the transaction process of a user and a seller, the situation that the user performs transaction with the seller through a credit line is often existed, but the credit line of the user is insufficient, in order to promote the achievement of the transaction of the user and the seller and meet the transaction requirements of the user, the user can improve the credit line in a mode of 'pledge' of resources, and particularly in the process of quota improvement, the resources of the user need to be firstly frozen, and then the credit line of the user needs to be improved; correspondingly, in the process of releasing the pledge, the credit line of the user needs to be reduced firstly, then the frozen resource is released, and once the resource freezing and the credit line increasing processing are asynchronous or the credit line decreasing processing and the resource releasing processing are asynchronous, the situation that the resource of the user is frozen but not successfully increased or the situation that the resource of the user is decreased but not released may occur.

In the resource processing method based on the distributed transaction provided by this embodiment, in order to avoid increasing or decreasing the credit line of the user and asynchronous with the resource freezing or resource releasing, the distributed transaction is introduced, the increasing or decreasing of the credit line of the user and the resource freezing or resource releasing are used as atomic actions of the distributed transaction, and the execution synchronicity of the user and the resource is ensured by two-stage submission of the distributed transaction, so that the synchronicity of the user's resource and the credit in the process of the quality assurance is ensured.

The user in this embodiment refers to a personal user or an enterprise user who proposes to perform a pledge on resources to obtain an increase in the credit line. For example, the trading platform proposes a trading user who carries out a pledge on account funds to obtain an increased credit trading limit.

The resources refer to data resources, funds, stocks, insurance policies, bonds and the like in the user account. The credit line is a resource usage line which is credited to the user within a specified time limit according to factors such as credit information, income level and various asset values of the user, and the user has the right to dominate the resource within the usage line within the specified time limit. Although the user has the right to draw or use the resources in the credit line, the user needs to return the resources used in the credit line within a predetermined period after using the resources in the credit line. For example, according to the historical credit information, income level and various asset values of the user A, 4000 yuan of credit line is granted to the user A, and the user A can draw or use the 4000 yuan of the credit line, but the amount drawn or used in the credit line in the previous month needs to be refunded in a settlement period according to the monthly credit settlement period of the credit line.

The resource pledge request is a pledge processing request for pledge processing of the resource selected by the user, and the resource pledge request comprises the resource type of the resource to be pledged selected by the user and the resource application amount. For example, the resource type included in the resource pledge request submitted by the user is a fund type, and the resource application amount is 1000 yuan, that is, the user wants to pledge the 1000 yuan of fund in the fund account to increase the credit line.

In specific implementation, in order to improve the awareness degree of the user on the resource pledge and the credit line, in an optional implementation manner provided in this embodiment, before the resource pledge request submitted by the user is obtained, a resource custom selection and evaluation implementation is provided for the user, which is specifically implemented as follows:

receiving a resource pledge request submitted by the user;

and calculating a credit line corresponding to the resource pledge amount of the resource type according to the resource pledge amount and the credit conversion ratio corresponding to the resource type, and returning the credit line to the user. The credit transfer ratio is a ratio of the increase amount of the credit line determined according to the resource value of the pledged resource, for example, the credit transfer ratio of the fund type resource is 1:1, and the credit transfer ratio of the policy type resource is determined according to the premium or the premium.

For example, after receiving a resource pledge request submitted by a trading user a of a trading platform, according to a user ID of the trading user a included in the resource pledge request, reading a resource amount of each resource type resource in a resource account of the trading user a from a resource database of the trading platform and displaying the resource amount to the trading user a, and after displaying the resource amount of each resource type resource in the resource account of the trading user a, obtaining a resource type selected by the trading user a based on the displayed resource amount of each resource type resource and a submitted resource pledge amount, specifically, the resource type selected by the trading user a is a fund type, the submitted resource pledge amount is 5000 yuan, and a credit conversion ratio corresponding to the resource of the fund type is 1:1, that is: each pledge has 1 yuan of capital, and the promotion amount of the credit line is also 1 yuan; then sends and displays 5000 yuan of credit line calculated according to 5000 yuan of resource pledge amount and the credit conversion ratio of 1:1 to the trading user A.

And step S104, creating a distributed transaction based on the resource pledge request.

In this embodiment, the distributed transaction includes a resource freezing operation performed on the resource account of the user, and an increase operation performed on the credit line granted to the user.

Performing a quality-giving operation of resource freezing on the resource account of the user, namely performing authority limitation on resources in the resource account of the user, wherein the resources cannot be transferred or used by the user after being frozen; the frozen resources can restore the authority through unfreezing operation, and the user can normally transfer or use the resources after the authority is restored.

The operation of carrying out the quota increase on the credit line of the user refers to carrying out quota increase processing on the credit line of the user, and the user has the use and administration authority on the credit line increased after the quota increase processing.

It should be noted that the distributed transaction in this embodiment refers to a distributed transaction implemented based on a two-phase commit protocol, and the distributed transaction includes two atomic operations, namely a dequeue operation of performing resource freezing on a resource account of the user and an add operation of adding an amount to a credit line of the user. The execution of the distributed transaction comprises two phases, wherein the first phase is a pre-execution phase, and the execution of the second phase is carried out on the basis of the execution result of the first phase.

And step S106, executing the pre-freezing operation of the out-of-quality operation by calling a resource service, and executing the pre-quota operation of the quota operation by calling a credit service, and executing the first-stage execution on the distributed transaction.

The resource service in this embodiment is a service for providing a pledge for resources in a resource account of a user, where the user may apply for pledge for the resources in the resource account through the resource service, and in practical applications, the resource service may be set to be extensible according to a change of a resource type in the resource account of the user, so that the resource service may perform pledge management for the resources in the resource account according to the change of the resources in the resource account of the user.

The pre-freezing operation refers to pre-freezing the resource under the resource type in the resource account according to the resource application amount. The usage right of the frozen resource in the resource account after the pre-freezing process is limited. For example, if the resource type included in the resource pledge request submitted by the user is the fund type and the resource application amount is 1000 yuan, then the 1000 yuan resource in the resource account of the user is pre-frozen, that is, the use permission of the 1000 yuan resource account by the user is limited, and after the permission is limited, the user cannot transfer or use the 1000 yuan resource.

In order to improve the processing efficiency of the pre-freezing operation and avoid the situation that the available amount of the resource account of the user is insufficient in the execution process of the pre-freezing operation, in an optional implementation manner provided by this embodiment, the resource account of the user is detected before the execution of the pre-freezing operation, which is specifically implemented as follows:

if so, pre-freezing the resources under the resource types in the resource account according to the resource application amount; the usage right of the frozen resource in the resource account after the pre-freezing process is limited; generating an execution success message that the execution of the pre-freezing operation is successful;

For example, the resource type included in the resource pledge request submitted by the user is a fund type, the resource application amount is 1000 yuan, whether the fund amount of the available fund in the resource account of the user is greater than or equal to 1000 yuan is judged, if so, pre-freezing processing is performed on the 1000 yuan fund in the resource account of the user, namely, the use permission of the 1000 yuan in the resource account of the user is limited (after the permission is limited, the user cannot transfer or use the 1000 yuan); if the 1000-element pre-freezing processing in the resource account of the user is successful, generating an execution success message that the pre-freezing processing is successfully executed; and if the 1000-element pre-freezing processing in the resource account of the user fails, generating an execution failure message that the execution of the pre-freezing processing is successful.

The credit granting service in this embodiment refers to a service for managing the credit granting amount of the user, for example, a credit granting service for performing an increase, a decrease and an admission decision on the credit granting amount of the user. And the pre-quota-increasing operation refers to pre-quota-increasing processing on the credit line of the user according to the application line carried in the resource pledge request. And the use authority of the new credit line after the pre-quota processing is limited. For example, if the credit line of the user before the increase processing is 4000 yuan and the application line carried in the resource pledge request submitted by the user is 1000 yuan, the credit line of the user is increased from 4000 yuan to 5000 yuan, but the 1000-yuan new increase between 4000 yuan and 5000 yuan in the credit line of the user is limited in use authority, and the user cannot use the 1000-yuan new increase to perform transaction.

if so, carrying out pre-quota processing on the credit line of the user according to the application line carried in the resource pledge request; the use authority of the new credit line after the pre-quota processing is limited; generating an execution success message that the execution of the pre-quota operation is successful;

And step S108, performing second-stage execution on the distributed transaction according to the execution messages returned by the resource service and the credit service after the first-stage execution.

After the resource service and the credit service are called to perform the first-stage execution on the distributed transaction according to the step S106, an execution strategy for performing the second-stage execution on the distributed transaction is determined according to the execution messages returned by the resource service and the credit service, and the second-stage execution is performed on the distributed transaction according to the determined execution strategy.

In an optional implementation manner provided in this embodiment, two atomic operations, namely a dequeue operation and a quota operation, included in the distributed transaction are executed as a whole, and according to an execution message of the dequeue operation returned by the resource service and an execution message of the quota operation returned by the credit granting service, second-stage execution of the distributed transaction is divided into two ways:

the first mode is as follows: if at least one of the execution message of the quality-out operation returned by the resource service and the execution message of the quota-increasing operation returned by the credit service is an execution failure message, it indicates that at least one of calling the resource service to perform the quality-out operation and calling the credit service to perform the quota-increasing operation fails to perform execution, calling the resource service to perform rollback on the pre-freezing operation performed in the first stage, and/or calling the credit service to perform rollback on the pre-quota-increasing operation performed in the first stage.

Wherein rolling back the pre-freeze operation performed in the first stage comprises: releasing the use permission of the resources which are subjected to the pre-freezing processing in the resource account;

rolling back the pre-quota operation performed in the first stage, comprising: and recovering the credit line of the user to a state before pre-quota processing.

For example, after the resource service is called to execute the pre-freezing operation, the 1000-yuan funds in the resource account of the user are successfully frozen, the execution message returned by the resource service after the pre-freezing operation is executed is an execution success message, and after the credit granting service is called to execute the quota improving operation, specifically in the process of improving the credit granting amount of the user from 4000 yuan to 5000 yuan, the execution message returned by the credit granting service after the pre-quota improving operation is an execution failure message, under the condition, the pre-freezing operation successfully executed by the resource service is rolled back, specifically, the use permission of the limited 1000-yuan funds in the resource account of the user is released;

or, after the resource service is called to execute the pre-freezing operation, the method comprises the following steps: in the process of freezing 1000 yuan of funds in a resource account of a user, an execution message returned by the resource service after prefreezing operation is an execution failure message, and after calling a credit granting service to execute a pre-rating operation, successfully rating the credit line of the user from 4000 yuan to 5000 yuan, and an execution message returned by the credit granting service after the pre-rating operation is an execution success message.

The second mode is as follows: if the execution message of the qualification operation returned by the resource service and the execution message of the quota operation returned by the credit service are both the execution success messages, the qualification operation carried out by calling the resource service and the quota operation carried out by calling the credit service are both successfully executed, the resource service is called to submit the pre-freezing operation, and the credit service is called to submit the quota operation.

Wherein submitting the pre-freeze operation comprises: confirming the limitation of the use permission of the resources subjected to the pre-freezing processing in the resource account, and updating the confirmation result into a resource database;

submitting the pre-quota operation, comprising: and releasing the limitation of the use authority of the newly added credit line of the credit line, and updating the release processing result to the credit database.

For example, after calling the resource service to execute the pre-freezing operation, the 1000 yuan funds in the resource account of the user are successfully frozen, the execution message returned after the resource service performs the pre-freezing operation is an execution success message, and after calling the credit granting service to execute the pre-quota operation, the credit granting quota of the user is successfully increased from 4000 yuan to 5000 yuan (the use authority of the 1000 yuan new quota between 4000 yuan and 5000 yuan in the credit granting quota is limited), the execution message returned by the credit granting service performing the pre-quota operation is also an execution success message, the freezing of the 1000 yuan funds in the resource account of the user is confirmed, the freezing result is updated to the resource database, the limit of the use authority of the 1000 yuan new quota in the credit granting quota of the user is removed, and the credit granting quota of the user is updated to 5000 yuan in the credit granting database.

As described above, for the resource pledge request submitted by the user, according to the execution result of the second-stage execution of the distributed transaction, if the second-stage execution of the distributed transaction is the rollback of the pre-freezing operation and/or the pre-quota operation executed in the first stage, a resource pledge failure message indicating that the execution of the resource pledge request fails is sent to the user; and if the execution of the second stage of the distributed transaction is confirmed and submitted to the pre-freezing operation and the pre-quota operation executed in the first stage, sending a successful resource pledge message of successful execution of the resource pledge request to the user.

The resource processing method based on the distributed transaction is further explained below by taking the application of the resource processing method based on the distributed transaction in the pledge scene as an example, and the resource processing method based on the distributed transaction applied to the pledge scene is specifically realized as follows:

1) acquiring a resource pledge request submitted by a user;

2) creating a distributed transaction based on the resource pledge request; the distributed transaction comprises the operation of resource freezing for the resource account of the user and the operation of quota increasing for the credit line of the user;

3) executing a pre-freezing operation of the out-of-service operation by calling a resource service, and executing a pre-quota operation of the quota operation by calling a credit service, and executing a first-stage execution on the distributed transaction;

the credit line of the pre-quota increasing operation is obtained by calculation according to the resource pledge amount of the pre-freezing operation and the credit conversion ratio corresponding to the resource type;

4) if the execution message returned by the resource service and/or the credit service is an execution failure message, releasing the use permission of the resources subjected to pre-freezing processing in the resource account, and restoring the credit line of the user to the state before the pre-quota processing;

and if the execution messages returned by the resource service and the credit service are successful execution messages, confirming the pledge authority of the resources which are pre-frozen in the resource account, and confirming the use authority of the user to the newly added credit line of the credit line.

The distributed transaction also comprises a pledge monitoring operation, and the resource service is called to roll back the prefreezing operation and the credit service is called to roll back the pre-quota promoting operation under the condition that the change of the resource attribute of the prefrozen resource is monitored in the execution process of the pledge monitoring operation, namely: releasing the use permission of the resources subjected to the pre-freezing processing in the resource account, and recovering the credit line of the user to a state before the pre-quota processing;

or, when the resource attribute of the resource of which the pledge authority is confirmed is monitored to be changed (for example, the pledge policy is in danger, and the digital certificate or certificate of the pledge of the user is updated) in the pledge monitoring operation execution process, generating and executing a reverse transaction of the distributed transaction (namely, pledge canceling transaction), wherein the pledge canceling transaction comprises pledge canceling operation and de-rating operation; the operation of discharging the quality and the operation of releasing the pledge are reverse operations, and the operation of increasing the amount and the operation of decreasing the amount are reverse operations.

In addition, the distributed transaction also comprises a pledge monitoring operation, and whether pledge authority of the prefrozen resource is confirmed is judged under the condition that the resource attribute of the prefrozen resource is monitored to be changed in the execution process of the pledge monitoring operation; if yes, removing the affairs and executing the pledge corresponding to the distributed affairs; if not, calling the resource service to roll back the pre-freezing operation, and calling the credit service to roll back the pre-quota operation.

To sum up, the resource processing method based on distributed transactions provided in this specification creates a distributed transaction including two operations, namely, a qualification operation and a quota operation, after acquiring a resource pledge request submitted by a user, performs a first-stage execution on the distributed transaction by invoking a resource service and a credit granting service, performs a second-stage execution on the distributed transaction according to a first-stage execution message returned by the resource service and the credit granting service, and enables the qualification operation and the quota operation to be executed synchronously by performing the two stages of the distributed transaction, thereby ensuring that resources of the user and credit granting operation are kept synchronous in a pledge processing process.
