Get Request

package main

	"io"
	"net/http"
)

func main() {

	client := &http.Client{}

	// build get request
	getURL := "http://10.211.55.10:12345/"
	getReq, err := http.NewRequest("GET", getURL, nil)
	if err != nil {
		fmt.Println("Error creating GET request:", err)
		return
	}

	// set HTTP 1.1 Keep-Alive header
	getReq.Header.Set("Connection", "keep-alive")

    // 發送10個get request
	for i := 0; i < 10; i++ {
		wg.Add(1)

		go func() {
			defer wg.Done()

			// execute get request
			getResp, err := client.Do(getReq)
			if err != nil {
				fmt.Println("Error sending GET request:", err)
				return
			}
			defer getResp.Body.Close()

			body, err := io.ReadAll(getResp.Body)
			if err != nil {

				return

			fmt.Println("response body:", string(body))
		}()

		wg.Wait()
	}
