Registration discovery of services is two processes.
The service registration is to register service information including service name, service instance ID, IP address of server where the service operates, etc. to service directory for other service to query. Service discovery is to query on which IP the service runs by the name of the service and address the service through IP and port. The service may then complete the requested access to the service based on the IP: port information and issue a request for a response. Because the service is started in the container, the registration of the starting position can be completed when the container is started, and thus, the service registration is not required to be realized in the code of the service.
Discovery of services is difficult if not impossible to accomplish through code. The main reason is that the service request initiator is not known to which service the initiated API request should be directed, i.e. the service name part content when the service query is missing.
In order to solve the problems, the invention provides a service registration discovery method, which is used for reading an API interface with an open service through interface interpretation, acquiring name parameter information of an accessed API through a request hook, inquiring a service directory about which service the interface is provided by, and completing service discovery addressing.
As shown in FIG. 1, the service registration discovery method provided by the embodiment of the invention comprises S110-S130.
S110, registering service name information, node IP, service port number of the service, and name and interface parameters of an external API interface of the service into a service catalog in the process of loading and starting the service by the cloud platform.
S110 is a service registration process, and specifically includes S111-S113.
S111, when the cloud platform operates and loads the service, the service installation and loading tool of the cloud platform reads service name information contained in the configuration information of the service, and registers the information hosting into a service directory. Wherein, when packaging the service, the service name information and the like are injected into the configuration information of the service.
And S112, after the service is started on the cloud platform, the cloud platform acquires the node IP and the service port number of the service operation, and registers the IP and the port information of the service into the service catalog, wherein the service related attribute information is acquired.
S113, reading an installation package binary file (usually a so file) of the service, and searching the name and interface parameters of an external API interface of the service. Specifically, the external API interface name (generally ASIIC form) stored in the GOT/PLT segment in the so file is searched, and the corresponding interface parameter (binary form) is found through the offset of the external API interface in the GOT/PLT. And registering the interface name and the interface parameter into the service catalog, so as to finish the service registration process.
S120-S130 are service discovery processes.
S120, after the service starts up, an access request is initiated to the outside (upstream service), and the request is mainly sent in the form of RPC or Restful. The network sniffing module based on the cloud platform intercepts an access request externally initiated by a service, wherein the access request comprises a random IP Address (ASIIC), a random service port number (ASIIC), and a name (ASIIC) and interface parameters (binary) of a target API.
S130, confirming the target service of the access request in the service catalog based on the name of the target API and the interface parameter.
S130 includes S131-S133.
S131, analyzing the intercepted access request, decomposing an API name, inquiring the name of the target API in the service directory, and confirming whether the service providing the target API exists in the service directory.
S132, when the service providing the target API exists, confirming whether the interface parameters of the target API are matched with the interface parameters in the service catalog.
And S133, when the interface parameters of the target API are matched with the interface parameters in the service catalog, determining that the service providing the target API is the target service.
After confirming the target service, the method further includes S140.
S140, the random IP address and the random service port number in the access request are modified and replaced by the node IP and the service port number registered in the service directory by the target service; and forwarding the modified access request to the target service.
The service registration discovery method provided by the embodiment of the invention does not need to modify the service code, and reads the API interface of the service open to the outside through interface interpretation; and acquiring name parameter information of the accessed API through the request hook, and inquiring the service directory about which service the interface is provided by, so as to complete service discovery addressing.
As shown in fig. 2, the service registration discovery apparatus provided in the embodiment of the present invention includes a service registration module 210, a request interception module 220, and a target discovery module 230.
The service registration module 210 is configured to register service name information, node IP, service port number of a service, and name and interface parameters of an external API interface of the service into a service directory in a process of loading and starting the service by the cloud platform.
The request interception module 220 is configured to intercept, by using the cloud platform-based network sniffing module, an access request initiated by the service to the outside after the service is started and run, where the access request includes a random IP address, a random service port number, and a name and interface parameter of a target API.
The object discovery module 230 is configured to confirm the object service of the access request in the service directory based on the name of the object API and the interface parameters.
Further, the device is further used for replacing the random IP address and random service port number modification in the access request with the node IP and service port number registered in the service directory by the target service; and forwarding the modified access request to the target service.
It is understood that the service registration module 210, the request interception module 220, and the object discovery module 230 may be combined in one module to be implemented, or any one of the modules may be split into a plurality of modules. Or at least some of the functionality of one or more of the modules may be combined with, and implemented in, at least some of the functionality of other modules.
