Go 语言压测并发请求脚本

1.背景

在性能测试场景中,需要进行评估服务的QPS和服务并发数.完全模拟程序并发数非go 语言channel和gorouting 莫属如下脚本内容

package mainimport (\"fmt\"\"net/http\"\"time\")func requestServer(ch chan <- string){resp, err := http.Get(\"http://192.168.1.12:88\")if err != nil {ch <- fmt.Sprint(err)return}ch <- fmt.Sprint(resp.Status)defer resp.Body.Close()}func main() {ch := make(chan string)count := 5000//开始计时begin := time.Now()fmt.Println(\"开始时间:\", begin)for i := 0; i<= count; i++ {go requestServer(ch)}for y := 0; y<=count; y++ {fmt.Println(<-ch)}end := time.Now()fmt.Println(\"结束时间:\", end, time.Since(begin))}
