golang随机生成N位随机数下面直接上代码//随机生成6位验证码 package main import ( "fmt" "math/rand" "strconv" "time" ) func main() { //先用纳米的时间戳初始化随机种子 rand.Seed(time.Now().UnixNano()) //验证码初始化 var code string //需要生成的随机数量，根据自己的需要修改这个值 var num int = 4 //使用for循环 for i := 0; i < num; i++ { //验证码拼接，因为 i 是整形，需要先转为字符串 code += strconv.Itoa(rand.Intn(10)) } fmt.Println(code) } 结果如下图所示

    I think what you composed made a lot of sense. However, consider this, what if you added
    a little content? I mean, I don't wish to
    tell you how to run your blog, however suppose you added something that makes people desire more?
    I mean 个人介绍 - Dcr163的博客 is kinda boring.
    You ought to look at Yahoo's home page and watch how
    they create news headlines to get viewers to open the
    links. You might add a related video or a related picture or two
    to grab people excited about what you've
    got to say. Just my opinion, it would make your posts a little livelier.

    Everything published was actually very reasonable. But, think about this,
    suppose you were to create a awesome headline?

    I ain't saying your content is not good, however suppose you added a headline
    that grabbed folk's attention? I mean rabbitmq-server line 85: erl: command not found 报错 - Dcr163的博客 is a little plain. You could peek at Yahoo's
    home page and see how they create article titles to grab viewers to open the links.
    You might add a related video or a picture
    or two to grab people excited about what you've got to say.
    Just my opinion, it would bring your posts a little bit more interesting.

    I believe what you posted made a bunch of
    sense. But, think on this, suppose you added a little content?
    I am not saying your content isn't solid, but what if
    you added something that grabbed folk's attention? I mean 个人介绍 -
    Dcr163的博客 is a little vanilla. You ought to peek
    at Yahoo's front page and see how they create news titles to get people to open the links.
    You might try adding a video or a picture or two to grab
    people excited about what you've written. Just my opinion,
    it would make your posts a little bit more interesting.
