With the rapid development of Internet applications, users' demand for services is becoming higher and higher, especially the requirements for service response speed. Therefore, how to improve service performance has become a challenge that developers need to face. An important question. In this context, using go-zero to implement high-performance web services has become a hot topic.
Go-zero is a tool for quickly building high-performance and scalable APIs in Go. It can easily build high-performance web services, supports RPC calls and access to RESTful APIs, and implements HTTP and GRPC frameworks, etc. kind of agreement.
Let’s introduce the process of using go-zero to implement high-performance web services.
1. Install go-zero
Installing go-zero is very simple. You only need to execute the following command:
go get -u github.com/tal-tech/go-zero
2. Create a project
We can use the goctl tool to quickly generate the go-zero project framework. The command is as follows:
goctl api new -o greet -d greet
Among them, "-o" indicates the specified project name, and "-d" indicates the specified module name.
3. Create a service
After creating the project framework, we need to create a service.
package services import ( "context" "greet/internal/model" "greet/internal/types" ) type InventoryService struct{} func NewInventoryService() *InventoryService { return &InventoryService{} } // 获取库存 func (s *InventoryService) GetInventory(ctx context.Context, req *types.InventoryRequest) (*types.InventoryResponse, error) { inventory := model.GetInventory(req.ProductId) if inventory == nil { return nil, ErrInventoryNotFound } return &types.InventoryResponse{ Inventory: inventory.Count, }, nil }
syntax = "proto3"; package greet; message InventoryRequest { int64 product_id = 1; } message InventoryResponse { int32 inventory = 1; } service Greet { rpc GetInventory(InventoryRequest) returns (InventoryResponse); }
goctl api rpc -api greet.proto -src . -dir .
package main import ( "flag" "github.com/tal-tech/go-zero/core/conf" "github.com/tal-tech/go-zero/core/service" "greet/internal/config" "greet/internal/server" "greet/internal/svc" ) var configFile = flag.String("f", "etc/greet-api.yaml", "the config file") func main() { flag.Parse() var c config.Config conf.MustLoad(*configFile, &c) ctx := svc.NewServiceContext(c) server := server.NewGreetServer(ctx) s := service.New(server, service.WithName(c.Name)) s.Start() }
4. Start the service
Execute the following command in the project root directory to start the service:
go run main.go -f etc/greet-api.yaml
5. Test the service
Use grpcurl to test the service. Use the following command to test the GetInventory method:
grpcurl -plaintext -proto rpc/greet.proto -d '{"product_id": 1}' localhost:8080 greet.Greet.GetInventory 输出结果如下: { "inventory": 10 }
At this point, we have successfully implemented a high-performance Web service using go-zero.
Summary: Using go-zero to implement high-performance Web services is relatively simple, and supports multiple protocols, which can help developers quickly build high-performance Web services. If you want to improve the response speed of your service, you might as well try using go-zero to build your web service!
