有一个 hacky 解决方案，利用这样一个事实，即您可以在完成其工作http.ResponseWriter后继续写入。http.FileServer一般不推荐，但在这种情况下它可能是可以接受的。package mainimport (&nbsp; &nbsp; &nbsp; &nbsp; "io"&nbsp; &nbsp; &nbsp; &nbsp; "log"&nbsp; &nbsp; &nbsp; &nbsp; "net/http")const (&nbsp; &nbsp; &nbsp; &nbsp; link = `<link rel="stylesheet" href="/path/to/style.css">`)func main() {&nbsp; &nbsp; &nbsp; &nbsp; fs := http.FileServer(http.Dir("/tmp"))&nbsp; &nbsp; &nbsp; &nbsp; var handler http.HandlerFunc&nbsp; &nbsp; &nbsp; &nbsp; handler = func(w http.ResponseWriter, r *http.Request) {&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; var (&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; url&nbsp; &nbsp;= r.URL.Path&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; isDir = url[len(url)-1] == '/'&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; )&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; fs.ServeHTTP(w, r)&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; if isDir {&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; io.WriteString(w, link)&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; }&nbsp; &nbsp; &nbsp; &nbsp; }&nbsp; &nbsp; &nbsp; &nbsp; log.Fatal(http.ListenAndServe(":8080", handler))}
