Go kit is a Golang microservice framework that improves API performance through optimized, scalable, maintainable and test-friendly functions. It provides a range of tools and patterns that enable users to quickly build performant and maintainable APIs. In actual production, it is widely used in API construction of large platforms such as Netflix, Spotify and Uber, handling massive requests.
Go kit framework: a powerful tool to improve the performance of Golang API
Introduction
Go kit is a lightweight Golang microservices framework designed to improve API performance and scalability. It provides a series of tools and patterns to help developers quickly build high-performance and maintainable APIs.
Code Example
The following is a code example using Go kit to create a simple API:
package main import ( "context" "net/http" "strconv" httptransport "github.com/go-kit/kit/transport/http" ) // 定义服务接口 type Service interface { Multiply(ctx context.Context, a, b int) (int, error) } // 定义服务实现 type service struct{} func (s service) Multiply(ctx context.Context, a, b int) (int, error) { return a * b, nil } func main() { // 创建服务实例 svc := service{} // 使用Go kit的httptransport创建一个HTTP端点 endpoint := httptransport.NewServer( makeMultiplyEndpoint(svc), decodeMultiplyRequest, encodeResponse, ) // 注册HTTP处理程序 http.Handle("/multiply", endpoint) // 启动HTTP服务器 http.ListenAndServe(":8080", nil) } // 定义端点函数 func makeMultiplyEndpoint(svc Service) httptransport.Endpoint { return func(ctx context.Context, r *http.Request) (interface{}, error) { a, err := strconv.Atoi(r.URL.Query().Get("a")) if err != nil { return nil, err } b, err := strconv.Atoi(r.URL.Query().Get("b")) if err != nil { return nil, err } return svc.Multiply(ctx, a, b) } } // 定义请求解码函数 func decodeMultiplyRequest(ctx context.Context, r *http.Request) (interface{}, error) { a, err := strconv.Atoi(r.URL.Query().Get("a")) if err != nil { return nil, err } b, err := strconv.Atoi(r.URL.Query().Get("b")) if err != nil { return nil, err } return multiplyRequest{A: a, B: b}, nil } // 定义响应编码函数 func encodeResponse(ctx context.Context, w http.ResponseWriter, response interface{}) error { w.Header().Set("Content-Type", "application/json") return json.NewEncoder(w).Encode(response) } // 定义multiplyRequest结构体用于请求 type multiplyRequest struct { A int B int }
Practical Case
In actual production environments, Go kit can be used to build highly scalable APIs and handle large numbers of requests. Here are some practical examples:
