Step 2: Install: Go version go1.11 linux/amd64

Step 3: Install: Go libraries

• $ go get -u google.golang.org/grpc

• $ go get -u github.com/golang/protobuf/protoc-gen-go

• $ go get xorm.io/xorm

• $ go get github.com/pilu/fresh

• $ go get github.com/labstack/echo

• $ go get github.com/go-sql-driver/mysql

• $ go get github.com/dabory/abango

• $ go get github.com/dabory/kafka-docker

• $ go get github.com/dabory/svc-abango

• $ go get github.com/dabory/end-abango

• $ go get github.com/go-xorm/xorm

* Here is install shell file for Go librariesis: goget_all.sh

Step 4: Run kafka service (Not necessary if using gRpc and REST API only)

To run Apache Kafka, use this command in one terminal mode

• $ cd $GOPATH/src/

• $ git clone https://github.com/dabory/kafka-docker

• $ cd $GOPATH/src/kafka-docker

• $ docker-compose up

Step 5: Run abango service

To run service, use this command in another terminal mode

• $ cd $GOPATH/src/github.com/dabory/svc-abango

• $ vi conf/config_select.json ....... ; specify config.json file which has xxx prefix in file name

• $ vi conf/xxx_config.json ....... ; change parameter values linked conf file if necessary

• $ fresh ....... ; run service

Step 6: To test end-point request and service running

To run request, use this command in the other terminal mode

• $ cd $GOPATH/src/github.com/dabory/end-abango

• $ vi conf/config_select.json ....... ; specify config.json file which has xxx prefix in file name

• $ vi conf/xxx_config.json ....... ; change parameter and select service api if necessary

• $ go run main.go login ....... ; run a request and it returns same value in file ./json-send/login.json

You will get :

[ReturnStatus: 200 ReturnJsonFile: json-receive/login.json]

[{

"UserId": "admin",
"Password": "admin-password"

}]

Kafka API Procedure

It is crucial in Kafka messaging service to syncronize producing messages and acquire return messages from backend as RESTful API and gRpc API do.
