Further, the flow control management system 12 obtains a server initial value, determines a server identifier for providing a service for the target transaction request according to the server initial value, and transmits the transaction request to a server corresponding to the server identifier in the server cluster 10. In the case where the number of transaction requests is equal to or greater than the total number, excess flow control information is transmitted to the client 11.

In addition, the flow control architecture provided by the embodiment of the application can be applied to a low-flow control scene that the number of flow control parameters is smaller than the number of servers, and can realize accurate control of flow control.
In view of the foregoing flow control architecture, a flow control method according to an embodiment of the present application is described in detail below with reference to fig. 2.
Fig. 2 is a flow chart illustrating a flow control method according to an embodiment of the present application, where the flow control method may be applied to the flow control management module in the flow control architecture.
As shown in fig. 2, the flow control method specifically includes the following steps:
s110, receiving a target transaction request, wherein the target transaction request can include an identification of a requesting device.
The target transaction request may be a transaction request sent by any requesting device, and may include an identification of the requesting device, where the identification of the requesting device may be a character capable of uniquely identifying the requesting device, and may include a number, letter, symbol, and the like.
In one embodiment, a flow control field value in the target transaction request is obtained to obtain an identification of the requesting device.
S120, obtaining, from the database, the number of request device transaction requests and the total number of request device permission transaction requests, where the number of request device transaction requests and the total number of request device permission transaction requests may be preloaded from the flow control configuration module to the database.
The number of requesting device transaction requests and the total number of requesting device allowed transaction requests may be a number that is pre-configured by a database based on a flow control configuration module, wherein the database may be an in-memory database.
As an example, at service start-up, configuration information of the requesting device 1 is first pre-configured in the in-memory database from the flow control configuration module, including the total number of allowed transaction requests, i.e. the maximum number of requests, and the number of current transaction requests of the requesting device 1, i.e. the current number of requests, for subsequent fast query use. When the flow control is 3 for the requesting device 1, the data initialized according to the demand of the requesting device 1 may be: requesting device 1: { number of current requests: 0, maximum number of requests: 3}. Next, the number of transaction requests 0 of the requesting device 1 is obtained from the in-memory database, and the total number of transaction requests 3 allowed by the requesting device 1.
And S130, recording and updating the current transaction request number of the request equipment to be one more than the number of the transaction requests under the condition that the number of the transaction requests is smaller than the total number, and acquiring the initial value of the server from the database.
As an example, after the number of current transaction requests of the requesting device 1 is configured in the database to be 0, and the total number of allowed transaction requests of the requesting device 1 is 3, when the transaction request a is received, the current configuration information in the database is queried, whether the transaction request a is within the flow control range is judged, that is, the total number of allowed transaction requests is 3-the number of current transaction requests is 0= 3>0, the number of transaction requests is smaller than the total number, and the transaction request a is judged to pass. The pre-configured server initial value in the database is then obtained, which may be-1, for example, for subsequent determination of the server that serves the transaction request a. In addition, the number of the current transaction requests is added by 1 and the database is written back as the updated number of the current transaction requests of the requesting device 1.
And S140, determining a server identifier for providing service for the target transaction request according to the initial value of the server, and sending the target transaction request to a server corresponding to the server identifier.
The server initial value may be a server subscript value for selecting to invoke the server, for example, when the server initial value is-1, the server subscript is stored in the database: -1.
As an example, at the time of service start, an array of server information is preconfigured in the stored database, for example, the cluster includes 12 servers, and the initialized data according to the requirement may be: server information array= [ { server 1}, { server 2}, { … } ], server subscript: -1. And then, when the transaction request A is received and judged to be in the flow control range, a server index value-1 is obtained from the cluster database, a server identifier for providing service for the transaction request A is determined according to the server index value-1, and the transaction request A is sent to a server corresponding to the server identifier.
And S150, when the number of the transaction requests is greater than or equal to the total number, sending the excess flow control information to the requesting equipment.
The excess flow control information may be feedback information for prompting the requesting device that the transaction request exceeds flow control.
As an example, when the flow control is 3 for the requesting device 1, upon receiving the transaction request B of the requesting device 1, the current configuration information in the database is queried, and it is determined whether the transaction request B is within the flow control range, that is, the total number of allowed transaction requests 3 of the requesting device 1—the number of current transaction requests 3=0, and the number of transaction requests is equal to the total number, then the transaction request B does not pass, and no information exceeding the flow control is transmitted to the requesting device 1 within the flow control range.
In the embodiment of the application, the target transaction request comprising the identification of the request device is received, the number of the transaction requests of the request device is obtained from the database, and the total number of the transaction requests allowed by the request device is preloaded from the flow control configuration module to the database, so that the efficiency of inquiring the number of the transaction requests in the follow-up process is improved. And then, under the condition that the number of the transaction requests is smaller than the total number, recording and updating the current transaction request number of the request equipment to be one, obtaining a server initial value from a database, determining a server identifier for providing service for the target transaction request according to the server initial value, and sending the target transaction request to a server corresponding to the server identifier. And sending the excess flow control information to the requesting device when the number of transaction requests is greater than or equal to the total number. According to the embodiment of the application, the flow control information of the request equipment is configured into the database through unified logic control, cluster sharing is achieved, flow control can be conducted on different request equipment in the clusters, when each transaction request arrives, flow control data in the database are updated, and accurate control of the flow control data is achieved.
According to the method and the device for controlling the server, the server initial value is obtained from the cluster database, the server identifier for providing service for the target transaction request is determined according to the server initial value, and the server in the cluster database can be accurately selected for calling, so that accurate control of the servers in the cluster is achieved.
In some embodiments, the database may comprise a clustered database; s140: the determining, according to the initial value of the server, a server identifier for providing service for the target transaction request may specifically include:
and determining the sum of the initial value of the server and the preset value, and taking the remainder of dividing the sum of the initial value of the server and the total number of the servers in the database as the server identification.
The cluster database may be used to store a server cluster, where a server identifier and a server initial value may be stored in the cluster database, and the preset value may be a value arbitrarily set by a user according to needs, for example, may be 0 or 1, which is not limited herein.
As an example, a cluster includes 12 servers, and at service start-up, initialized data in the cluster database may be: server information array= [ { server 1}, { server 2}, { … } ], server subscript: -1. When a transaction request A is received and the transaction request A is judged to be in a flow control range, a server index value of-1 is obtained from a cluster database, one server in a server information array is selected to provide service according to the server index value, the server index= (server index+1)% total number of servers is utilized, the remainder is calculated to be 0, namely the calculated server index is 0, and a server with the index value of 0 is called to provide service for the transaction request A.
In the embodiment of the application, the remainder of the sum of the initial value of the server and the preset value is calculated and divided with the total number of the servers in the database, and the remainder is used as the server identification, so that the selection of the servers in the cluster can be more accurate, and the calling accuracy of the servers in the cluster is further improved.
In some embodiments, the flow control method may further include:
and storing the remainder as an updated initial value of the server to the cluster database.
As an example, after receiving the transaction request a and calculating to obtain the remainder as 0 using the server index= (server index+1)% of the total number of servers, the calculated index is returned to the server information array of the cluster database, and the server index in the cluster database is updated to 0, that is, the server information array= [ { server 1}, { server 2}, { … } ], the server index: 0.
in the embodiment of the application, the remainder is stored as the updated initial value of the server to the cluster database, so that the server is conveniently called by the received transaction request.
In some embodiments, the database may include flow control configuration information; at S140: after sending the target transaction request to the server corresponding to the server identifier, the flow control method may further include:
inquiring the number of current transaction requests in the flow control configuration information of the request equipment;
subtracting one from the number of the current transaction requests of the requesting device to obtain the number of updated current transaction requests;
