[0028] Embodiment 1

[0029] Figure 1A flowchart of a distributed service access method is provided for the first embodiment of the present invention. This embodiment is applicable to the case where a user requests to access a distributed service. The method can be executed by a distributed service access device. The distributed service access device can be implemented in the form of hardware and / or software. The distributed service access device can be configured in various general-purpose computing devices, such as terminal devices in a distributed system. Figure 1 As shown, the method includes:

[0030] S110: Receive a usage request for a distributed service through a standard contract interface, and perform a first legality check on the usage request based on usage request information.

[0031] The use request information includes request format information and request identity information; optionally, the request identity information may be key information or digital signature information of the requesting party.

[0032] S120. Based on the access rules of the distributed service and the target distributed service to be accessed by the use request that has passed the first legal verification, perform a second legal verification on the use request; wherein the access rules are used to limit the access method, maximum access threshold and access rights of the distributed service.

[0033] Specifically, the usage request issued by the user for accessing the distributed service can be received through the standard contract interface, and the data integrity of the received usage request can be verified. The integrity check can be performed on the data fields in the usage request, including but not limited to verifying whether all required fields are contained in the field message. Any usage request that lacks key fields will be considered non-compliant and will be intercepted or marked for review. Optionally, in addition to verifying the data integrity, it is also possible to verify whether the data format of the usage request complies with the preset business standards or protocol specifications. The accuracy and readability of the usage request are further ensured to avoid misreading of information or processing failure due to format errors. Optionally, business standards or protocol specifications can be adaptively set according to technical personnel in this field.

[0034] Furthermore, for usage requests that pass the data integrity check, it is possible to determine whether the usage request can be responded to based on the access mode, maximum access threshold, and access rights of the target distributed service that the usage request is to access. Exemplarily, it is possible to first determine whether the sender of the usage request has the authority to reference the target distributed service. After determining that it has the access right, it is possible to determine whether the target distributed service can still be accessed by determining the access mode and access margin of the target distributed service. By continuously monitoring the operating status of the distributed service components, the stability and reliability of the service can be ensured. Optionally, access methods may include batch access and single access, etc.

[0035] During the process of receiving usage requests, you can also record the receiving logs to record key information such as the receiving time, source, type, and verification status of the usage request to achieve comprehensive audit and traceability capabilities.

[0036] S130. Based on the channel distributor, allocate a target distributed service to the use request that passes the second legal verification; wherein at least one distributed service is registered in the channel distributor.

[0037] Optionally, in an embodiment of the present invention, based on a channel distributor, a target distributed service is allocated to a usage request that passes a second legal verification, including: determining a target product channel of the usage request in the channel distributor according to the target distributed service to be accessed by the usage request that passes the second legal verification; wherein the target product channel is used to provide the target distributed service to be accessed by the usage request; determining a target product in the target product channel according to a product identifier carried in the usage request, and returning an access address of the target product as a response result.

[0038] In an embodiment of the present invention, a plurality of service products of a distributed service can be registered in the channel distributor. The registration process of the distributed product can be to configure the product identification and product access address of service products from different manufacturers for the same distributed service in the management control interface of the channel distributor after the service product is started. Optionally, a distributed service usually needs to be configured with a default service product. The channel distributor can determine the target product to be assigned to the use request by using the product identification carried in the use request. If the use request does not carry the product identification, the default service product will be selected as the target product of the use request.

[0039] It should be noted that, in the embodiment of the present invention, the standard contract interface defines at least one access process of a distributed service; the access process may include a first legal verification process, a second legal verification process and a target distributed service allocation process.

[0040] By defining the access process of distributed services by annotating contract interfaces, the internal logic of a module can be independently implemented without having to understand the specific implementation details of other modules. As long as the interface contract is followed, modules can collaborate seamlessly, ensuring the flexibility, maintainability and scalability of the system.

[0041] The technical solution of the embodiment of the present invention receives the use request of the distributed service through the standard contract interface, and processes the request response corresponding to the different use requests of the access object through the standard contract interface, thereby decoupling the system from the distributed service, realizing low-cost switching to different distributed services, reducing the system's dependence on a single distributed product, and improving the flexibility of the system in calling different distributed services.

[0042] Embodiment 2

[0043] Figure 2 This is a flow chart of a distributed service access method provided in the second embodiment of the present invention. This embodiment further refines the above embodiment and provides the specific process of the first legal verification and the second legal verification. It should be noted that for the undetailed parts of the embodiment of the present invention, please refer to the relevant descriptions of other embodiments, which will not be repeated here. Figure 2 As shown, the method includes:

[0044] S210: Determine the target distributed service requested by the use request according to the request identifier carried in the use request.

[0045] S220: Perform field verification on the usage request according to the standard request field corresponding to the target distributed service.

[0046] The request identifier can be used to characterize the distributed service to be accessed by the request, such as microservices, cache services, and database services.

[0047] For example, when the target distributed service to be requested by the request is a microservice, the target object to be accessed can be limited in the request identification field according to the standard protocol fields (request address identifier, request body identifier, and request header identifier) ​​in the standard communication protocol of the microservice, such as the product identification field and the request identification field.

[0048] Optionally, the first legal verification further includes: performing a key verification on the use request to determine whether the use request carries correct key information.

[0049] Specifically, the request header field of the use request carries request authentication information, such as digital signature information or requester key information, etc. After receiving the use request, the received use request can be authenticated according to the locally pre-stored requester key information to ensure the legitimacy of the use request identity.

[0050] S230: Determine the service lifecycle and access method access rights of the target distributed service according to the access rule of the distributed service.

[0051] S240: If the service lifecycle of the target distributed service has not expired, verify whether the use request has access rights to the target distributed service based on the identity information of the use request.

[0052] S250: In the case of having access rights, determine whether the current access volume of the target distributed service reaches the maximum access threshold; if not, it indicates that the second legal verification has passed.

[0053] In the embodiment of the present invention, the distributed services registered in the channel distributor have a certain life cycle, and the life cycle of each distributed service can be adaptively set according to those skilled in the art. Therefore, before accessing the distributed service, it is necessary to determine the service life cycle and access mode access rights of the target distributed service that the use request needs to access according to the pre-stored access rules of the distributed service.

[0054] Determine whether the service lifecycle of the target distributed service has expired. If so, stop responding to the use request and return a request failure alarm. If not, query whether the identity information of the use request exists in the access permission table of the target access object. If so, determine that the use request can access the target distributed service. If not, return a request failure alarm.

[0055] Furthermore, the access mode of the target distributed service includes batch access and single access. When the access mode of the target distributed service is single access, it is determined whether the target distributed service is being accessed. If not, it indicates that the second legal check has passed, and the use request can access the target distributed service; if so, it indicates that the second legal check has not passed, and the use request is placed in the message waiting queue of the target distributed service. When the access mode of the target distributed service is batch access, the number of real-time concurrent accesses to the target distributed service is determined, and the access margin of the target distributed service is determined based on the maximum access threshold of the target distributed service. If the access margin is empty, it indicates that the second legal check has not passed, and the use request is placed in the message waiting queue of the target distributed service; if the access margin is not empty, it indicates that the second legal check has passed, and the use request can access the target distributed service. Optionally, the maximum access threshold can be set adaptively according to those skilled in the art.

[0056] The technical solution of the embodiment of the present invention improves the efficiency, security and scalability of the system by verifying the fields of the received usage request itself and verifying the access resources in combination with the dynamic access traffic of the distributed service. It not only enhances the overall protection capability of the system, but also provides users with a more reliable and secure interactive environment.
