The exemplary embodiments and descriptions of the present invention are provided to explain the present invention, but not to limit the present invention. It should be noted that the embodiments and features of the embodiments in the present application may be arbitrarily combined with each other without conflict.
Fig. 1 is a schematic structural diagram of a current limiting system of a distributed server according to an embodiment of the present invention, and as shown in fig. 1, the current limiting system of the distributed server according to the embodiment of the present invention includes a service invocation end 1, a distributed current limiter 2, and a distributed server 3, where the service invocation end 1 is connected to the distributed current limiter 2 in a communication manner, and the distributed current limiter 2 is connected to the distributed server 3 in a communication manner. The service calling end 1 is an entrance for service calling and can initiate business transaction, and the service calling end 1 is, for example, terminal equipment arranged in channels such as counter, bank-enterprise interconnection, internet bank and the like; the service calling end 1 can assemble each service transaction into a message according to transaction elements to form a transaction request and send the transaction request to the distributed current limiter 2. The distributed current limiter 2 receives the transaction request, carries out current limiting processing on the transaction request, and forwards the transaction request which does not need current limiting to the distributed server 3. The distributed server 3 processes the received transaction request and returns a processing result. The distributed current limiter 2 is used for executing the current limiting method of the distributed server provided by the embodiment of the invention. It should be noted that the current limiting method for the distributed server provided in the embodiment of the present invention implements current limiting for the distributed server by controlling the number of transaction requests.
Fig. 2 is a schematic flow diagram of a current limiting method for a distributed server according to an embodiment of the present invention, and as shown in fig. 2, the current limiting method for a distributed server according to the embodiment of the present invention includes:
s201, receiving at least one transaction request;
specifically, the service invocation end sends at least one transaction request to the distributed current limiter, and the distributed current limiter receives the transaction request. The transaction request includes transaction elements, the transaction elements include but are not limited to a transaction type, a transaction account number, a transaction currency, a transaction amount, a transaction date, and the like, and the transaction elements are set according to an actual situation, which is not limited in the embodiment of the present invention.
S202, if the at least one transaction request is judged to have the transaction request meeting the current limiting judgment rule, acquiring the number of the transaction requests in unit time; wherein the current limit judgment rule is preset;
specifically, after receiving the at least one transaction request, the distributed current limiter determines whether each transaction request in the at least one transaction request satisfies a current limiting determination rule, and if there is a transaction request satisfying the current limiting determination rule, obtains the number of transaction requests in a unit time. Wherein the current limit judgment rule is preset. The current-limiting judgment rule is set according to actual needs, and the embodiment of the invention is not limited; the unit time is, for example, 1 second, and is set according to actual needs, which is not limited in the embodiment of the present invention. It will be appreciated that for transaction requests that do not meet the current limit determination rule, the distributed current limiter will be forwarded to a distributed server for processing. The distributed current limiter may be set on a gateway, a proxy server, or a distributed server, and is set according to actual needs, which is not limited in the embodiments of the present invention.
For example, the current limiting judgment rule includes a judgment condition: the transaction currency is Renminbi or USD. The transaction request satisfies the current limit determination rule if the transaction currency used in the transaction request is Renminbi or USD. The current limiting judgment rule comprises the following judgment conditions: the transaction amount is greater than 100 and less than 1000. If the transaction amount of the transaction request is greater than 100 and less than 1000, the transaction request satisfies the current limit determination rule. The current limiting judgment rule comprises the following judgment conditions: the transaction date is 11 months and 11 days. And if the transaction date of the transaction request is 11 months and 11 days, the transaction request meets the current limiting judgment rule. The current limiting judgment rule comprises the following judgment conditions: the transaction currency is U.S. dollars and the transaction amount is greater than 1000. If the transaction currency in the transaction request is U.S. dollars and the transaction amount is greater than 1000, then the transaction request satisfies the current limit determination rule. It is to be understood that the current limit determination rule may include a plurality of determination conditions.
S203, if the transaction request quantity in the unit time is judged and known to be larger than the current limiting threshold value, rejecting the transaction requests which exceed the current limiting threshold value and meet the current limiting judgment rule.
Specifically, after the transaction request number in the unit time is obtained by the distributed current limiter, the transaction request number in the unit time is compared with a current limiting threshold, and if the transaction request number in the unit time is greater than the current limiting threshold, the transaction request which exceeds the current limiting threshold and satisfies the current limiting judgment rule is rejected, that is, the transaction request which exceeds the current limiting threshold and satisfies the current limiting judgment rule is not forwarded to the distributed server for processing. The current limit threshold is preset, and the current limit threshold is set according to actual experience, which is not limited in the embodiments of the present invention.
For example, if the number of transaction requests of the transaction requests meeting the current limiting judgment rule is 10, and the number of transaction requests in the unit time exceeding the current limiting threshold value is 5, the distributed current limiter rejects 5 transaction requests of the transaction requests meeting the current limiting judgment rule, and the remaining 5 transaction requests are sent to the distributed server for processing. The distributed current limiter may randomly select 5 transaction requests meeting the current limiting judgment rule to reject, or select 5 transaction requests with later sending time to reject according to the sending time of each transaction request, and the setting is performed according to actual needs, which is not limited in the embodiment of the present invention.

S2022, if it is determined that the at least one transaction element satisfies the current limiting determination rule, determining that the transaction request satisfies the current limiting determination rule.
Specifically, after at least one transaction element is extracted from the transaction request, the distributed current limiter determines whether a transaction element meeting the current limiting determination rule exists in the at least one transaction element, and if a transaction element meeting the current limiting determination rule exists, the transaction requirement corresponding to the transaction element meets the current limiting determination rule.
