Based on foregoing description, Fig. 2 illustratively shows what a kind of API gateway service provided in an embodiment of the present invention updated
The process of method, the process can be by above-mentioned API gateway application executions.
As shown in Fig. 2, the process specifically includes:
Step 201, information is locally configured using acquisition in API gateway.
In the embodiment of the present invention, API gateway is applied in initial start-up, available pre-configured static configuration letter
Breath, the static configuration information can be XML format static information, wherein include global configuration information in the static configuration information
And provide the mark of service；API gateway, which is applied, carries out global configuration to distributed remote invocation framenort according to global configuration information,
Such as configure Subscriber, communication protocol；The mark for providing service refers to that the API gateway being currently configured is applied to API tune
The mark serviced provided by side, API gateway apply the mark according to the offer service, subscribe to the offer from Subscriber
Service, and the offer service is instantiated in the application container of API gateway application；Complete subscription service and instantiating services
Afterwards, API gateway, which is applied, is locally configured information according to the mark mark of service (the be equivalent to provide) determination of the subscription service.This
Place, instantiating services refer to that according to class and global configuration information, creation is specific in the application container of API gateway application uses
In the object of offer service.
Information can be locally configured with timing acquisition in API gateway application, this be locally configured information i.e. API gateway apply according to from
The mark determination of subscription service in Subscriber.Information is locally configured can be stored in the form of list is locally configured,
This is locally configured list and is made of mark service provider corresponding with the mark of the subscription service address of subscription service.
Step 202, API gateway is applied from dynamic configuration server and obtains dynamic configuration information.
User can manage the visualization interface of platform when needing to be updated API gateway service by API gateway
Dynamic configuration instruction is issued, dynamic configuration instruction applies the service subscribed to from Subscriber for changing API gateway, also
It is the service provided for changing API gateway to API Calls side.Illustratively, user is when needing to increase newly some API service,
Record, which can then be issued, the dynamic configuration instruction of mark of the newly-increased API service, and dynamic configuration server is according to dynamic configuration
It instructs and the dynamic configuration information being locally stored is updated, which is increased in the dynamic configuration information.
Dynamic configuration information, format Key-Value can be stored using Redis in dynamic configuration server, wherein
Key refers to that service identifiers of the API service in API gateway application, Value refer to the configuration information of the API service, such as most
Big access duration may be different for the configuration information of API service according to different far call frames.Illustratively, dynamic
Configuration information can be such that
{"apiservice1":"{\"serviceId\":\"api_service_id_1\",\"timeout\":\"
3000\"}","apiservice2":"{\"serviceId\":\"api_service_id_2\"}",}
In addition, dynamic configuration server can also use other Key-Value type databases to store dynamic configuration information,
Such as Memcached.Key-Value type database, which can be improved API gateway and apply to obtain from dynamic configuration server, dynamically matches
The speed of confidence breath.Certainly, dynamic configuration server can also use relevant database to store dynamic configuration information, such as
MySQL, Oracle etc..
Step 203, API gateway application, which is compared, is locally configured information and dynamic configuration information, however, it is determined that increases service newly out
First identifier then subscribes to newly-increased service from Subscriber according to first identifier, and real in the application container of API gateway application
The newly-increased service of exampleization.
API gateway application, which is compared, is locally configured information and dynamic configuration information, in a kind of implementation, API gateway application
If it is determined that information is locally configured less than dynamic configuration information, then the API for having newly-increased in current dynamic configuration information can be determined
The service identifiers first identifier of service (namely newly-increased) of service, can be according to the service identifiers of the newly-increased API service, from ordering
The subscription increased newly in server to the API service is read, and instantiates the newly-increased API service in application container.
Step 204, API gateway, which is applied, is locally configured information according to dynamic configuration information update.
Such as the process that Fig. 3 is the method that another API gateway service provided in an embodiment of the present invention updates, API gateway is answered
With Spring frame and the realization of Magpie distributed remote service call frame has been used, dynamic configuration server passes through Redis
To store dynamic configuration information.API gateway application on startup, obtains the static configuration information of XML format, API gateway application
Spring container can load Bean example, complete Magpie frame global configuration, and to Subscriber subscription service.API
After gateway application start completion, it is stored in memory using subscription service as information is locally configured.API gateway, which is applied, to be run
In, the dynamic configuration information of a full dose is reacquired from Redis every 1 minute (time configurable), and is saved in memory
The information that is locally configured be compared, if it find that newly-increased API service, then subscribe to the newly-increased API service from Subscriber
And the Bean example for increasing API service newly is loaded onto Spring container.API gateway applies the dynamic according to reacquisition
Information is locally configured in configuration information update.Information is locally configured it can be appreciated that being stored in the application memory of API gateway application
In dynamic configuration information copy.
After API gateway is applied and information is locally configured according to dynamic configuration information update, service call side can receive
Service request, wherein in the service request include service to be called mark, API gateway can according in service request to
It calls the mark of service to call from service provider to service.Specifically, the service that API gateway application receives service call side is asked
It asks, API gateway applies the mark according to service to be called, is determined in information from being locally configured for providing service to be called
The address of service provider, API gateway are real using the address according to service provider and in the application container of API gateway application
Service to be called after exampleization calls the service to be called from service provider and returns to service response to service call side.
In the embodiment of the present invention, API gateway application, which can also determine, is locally configured information more than dynamic configuration information, then may be used
To determine to delete the service identifiers of some API service in current dynamic configuration information, then API gateway application determines that this is deleted
Except the second identifier of service, and the second identifier is recorded in and has been deleted in identification information.This has been deleted in identification information and has recorded
There are all marks for having deleted service, is used for when service is called by API gateway application by service call side, if API gateway is answered
With determining that the service to be called is to have deleted the service recorded in identification information, then API gateway is applied and is returned to service call side
Return error message.Having deleted identification information can be by having deleted the deletion logo collection that forms of mark, which can also be with
It is called undercarriage set of service.Identification information has been deleted by setting, some API is deleted in determining dynamic configuration information
When the service identifiers of service, the service identifiers of the API service can be added to having deleted in identification information, thus realization pair
The undercarriage of API service.
In addition, API gateway not only can delete the by being recorded in second identifier to have deleted in identification information to realize
The purpose of the corresponding service of two marks directly can also unsubscribe second mark according to the second identifier from Subscriber
Know corresponding service, and goes to instantiate the corresponding service of the second identifier in API gateway application container.
In a kind of implementation, API gateway applies the mark according to service to be called, determines from being locally configured in information
Before the address of service provider for providing service to be called, it is also necessary to which, according to the mark of service to be called, judgement has been deleted
Except whether there is the mark of the service to be called in identification information, specifically, reading the mark of deletion of dynamic configuration server
Information executes decision logic, judges that this has deleted the mark that whether there is the service to be called in identification information, if so, directly
Return error message is connect, otherwise such as mistake HTTP response determines the clothes of service to be called according to the service identifiers of service to be called
The address of business provider, and then call service to be called from service provider and return to service response to service call side.
In foregoing invention embodiment, information and dynamic configuration information is locally configured in API gateway acquisition, to information is locally configured
It is compared with dynamic configuration information, however, it is determined that go out currently to have newly-increased service, then it is newly-increased to subscribe to this from Subscriber automatically
The newly-increased service is serviced and instantiated in application container, can also be updated automatically according to the dynamic configuration information and letter be locally configured
Breath.It is not necessary that updated static configuration information is manually replaced original static configuration information, and answered without restarting API gateway
