 你想知道用户输入的一个Email地址是否正确，通过如下这个方式可以验证：
 ```Go
 
-if m, _ := regexp.MatchString(`^([\w\.\_]{2,10})@(\w{1,}).([a-z]{2,4})$`, r.Form.Get("email")); !m {
+if m, _ := regexp.MatchString(`^([\w\.\_]{2,10})@(\w{1,})\.([a-z]{2,4})$`, r.Form.Get("email")); !m {
 	fmt.Println("no")
 }else{
 	fmt.Println("yes")
