我正在阅读 The Go Programming Language 一书，书中有一个例子说明了 goroutine 泄漏

func mirroredQuery() string {
    responses := make(chan string, 3)
    go func() { responses <- request("asia.gopl.io") }()
    go func() { responses <- request("europe.gopl.io") }()
    go func() { responses <- request("americas.gopl.io") }()
    return <-responses // return the quickest response
}
func request(hostname string) (response string) { /* ... */ }

我试图解决泄漏，并得到以下代码

func request(url string) string {
    res, err := http.Get(url)
    if err == nil {
        body, err := io.ReadAll(res.Body)
        if err == nil { …
