Example two
Fig. 3 is a flowchart of a method for invoking a microservice according to a second embodiment of the present invention, where the method is executed by a service dispatcher, and as shown in fig. 3, the method includes the following steps:
step 310, receiving an initial service scheduling request sent by a client.
The initial service scheduling request comprises an interface message, request information and service provider information. The interface message carries service data to be processed. In this embodiment, the micro-service scheduling is implemented by using RPC or message driven API.
Step 320, preprocessing the interface message, and encoding the preprocessed interface message and the request information and the service providing end information according to a set protocol format to obtain a target service scheduling request.
The process of preprocessing the interface message may be: carrying out field and/or type conversion on the interface message; and carrying out serialization processing on the converted interface message.
Specifically, mapping conversion of field and/or type conversion is performed on the interface message through an interface mapping layer. The implementation mode can be that a customized field type is added in the existing interface specification (such as json schema format), a new interface specification is formed, and then the conversion of the field and/or the type is carried out according to the new interface specification. Serialization processing can be realized by adopting serialization protocols such as kryo, session, thrift and the like, and the interface message is converted into a byte array.
The set protocol format may be an RPC protocol. Specifically, the serialized interface message is assembled and encoded according to an RPC protocol message format, and request information, service providing end information, and the like are added before a message load (payload), so as to obtain a target service scheduling request.
Step 330, call the local grid agent module of the service dispatcher to obtain the address list of the service provider according to the information of the service provider.
The local grid agent module integrates service management functions such as service discovery, registration, load balancing and the like. And the local network agent module acquires the address list of the service provider according to the information of the service provider.
Optionally, after the local grid proxy module is called, the method further includes the following steps: judging whether to carry out current limiting or fusing processing on the target service scheduling request; if so, rejecting the target scheduling request.
In this embodiment, the local grid agent module automatically controls the current limiting according to the time consumption of the request and the complexity of the service. The access is carried out through the unified gateway address (namely the address of the service provider), the gateway distributes the request to the specific service, and the processing result is returned in a unified mode.
Step 340, sending the target service scheduling request to the service provider according to the service provider address list.
And 350, receiving response data returned by the server, analyzing the response data and obtaining a processing result.
The method for analyzing the response data may be: and decoding, deserializing, field and/or type converting the response data.
Optionally, the method further comprises the following steps: performing link tracking on a service scheduling end to obtain tracking data; and uploading the tracking data to the provisioning server.
When complex business logic is realized, a plurality of micro services are generally involved, the execution failure of the business logic can be caused when any micro service fails, when the execution of the business logic fails, limited error information can be obtained from a link for calling transaction generally, and specific problems cannot be found. Meanwhile, after service call information is collected, the system can analyze the performance of the service call link, if a service provider with performance problems on the call link is found, emergency treatment notification messages such as service current limiting and fusing are generated according to a preset degradation rule, and the service current limiting or fusing notification is sent through a message middleware Message Queue (MQ). After receiving the relevant emergency notification, the service grid agent performs control logic processing such as current limiting and fusing in the RPC call link, and RPC index data acquired by link tracking can be analyzed in real time and fed back to the RPC component, so that the overall stability and usability of the system are ensured.
According to the technical scheme of the embodiment, an initial service scheduling request sent by a client is received; the initial service scheduling request comprises an interface message, request information and service provider information; preprocessing the interface message, and coding the preprocessed interface message and request information and service providing end information according to a set protocol format to obtain a target service scheduling request; calling a local grid agent module of a service scheduling terminal to acquire a service providing terminal address list according to service providing terminal information; sending a target service scheduling request to a service provider according to the address list of the service provider; and receiving response data returned by the server, and analyzing the response data to obtain a processing result. The scheduling of the micro-service is realized through the local grid agent module, the scheduling efficiency can be improved, and the separation of the business service and the service management is realized through the grid agent module, so that the cost of service development and maintenance can be reduced.
