我正在尝试在VPS上安装https://github.com/catarse/catarse脚本(在我的本地机器上工作正常),当我输入命令时出错bower install:

bower checkout      catarse_admin#master
bower resolved      https://github.com/catarse/catarse_admin.git#3151581f33
bower ENOTFOUND     Package option not found

如何合并两个数组？像这样的东西:

@movie = Movie.first()
@options = Movie.order("RANDOM()").first(3).merge(@movie)

但它不起作用.

在@options我需要一个包含四个元素的数组@movie.

当我尝试重启nginx并在控制台中写入此命令时

nginx -t

我有一个错误:

nginx: [emerg] a duplicate default server for 0.0.0.0:80 in /etc/nginx/sites-enabled/default.save:20
nginx: configuration file /etc/nginx/nginx.conf test failed

启用站点-/默认

server {
        listen 80 default_server;
        listen [::]:80 default_server ipv6only=on;

        server_name localhost;
        passenger_enabled on;
        rails_env    production;
        root         /home/hh/public;

        access_log  /var/log/nginx/host.access.log;
        # redirect server error pages to the static page /50x.html
        error_page   500 502 503 504  /50x.html;
        location = /50x.html {
            root   html;
        }
}

nginx.conf

user www-data;
worker_processes 4;
pid /run/nginx.pid;

events {
        worker_connections 768;
}

http {

        sendfile on; …

我有一点形式:

  = f.label :option_1, "title"
  = f.check_box :option_1

这是渲染:

如何从标签中删除" 选项1 "？

我正在使用路由器（httprouter）并希望从 root 提供静态文件。

css文件在

static/style.css

在模板中

<link href="./static/style.css" rel="stylesheet">

main.go

router := httprouter.New()
router.ServeFiles("/static/*filepath", http.Dir("/static/"))
router.GET("/", Index)

但是http://localhost:3001/static/style.css给了我一个 404 错误并且渲染页面中的样式也不起作用。

我有 SignUp 函数并尝试获取 Vue 框架发送的请求正文，但它是空的。

去

type SignUpForm struct {
    Username string
    Email    string
    Password string
}

func SignUp(c echo.Context) error {
    form := SignUpForm{
        Username: c.FormValue("username"),
        Email:    c.FormValue("email"),
        Password: c.FormValue("password")}

    user := models.User{
        Username: form.Username,
        Email:    form.Email,
        Password: models.HashPassword(form.Password),
    }

    log.Printf("#####################")
    values, _ := c.FormParams()
    log.Printf("%v\n", values)
    log.Printf("%v", c.Response().Header())
    log.Printf("#####################")

    err := database.Connection().Create(&user).Error
    if err != nil {
        return c.JSON(http.StatusInternalServerError, err)
    } else {
        return generateJwtToken(c, user)
    }
}

维埃

 sendForm: function() {
  var link = '/auth/sign_up'
  axios.post(link, { …

我想添加并发性来迭代嵌套循环，但遇到了麻烦。这个sync.WaitGroup 的示例用法有什么问题？

originCities := [3]string{"LED", "MOW", "PRS"}
destinationCities := [2]string{"UKT", "AAC"}

wg := &sync.WaitGroup{}
wg.Add(len(originCities) * len(destinationCities))

for _, originIata := range originCities {
    for _, destinationIata := range destinationCities {
        go func () {
            fmt.Println(originIata)
            fmt.Println(destinationIata)
            wg.Done()
        }()
    }
}
wg.Wait()

我越来越

PRS AAC PRS AAC PRS AAC PRS AAC PRS AAC PRS AAC

正如您所看到的，它跳过两个数组的第一个元素并仅迭代最后一个元素。有什么想法可以解决此行为吗？
