如何在 shiny 应用程序之前访问 html 页面

Question

The code below, when executed, first enters an html page, where it asks for a username and password.下面的代码在执行时首先进入 html 页面，在该页面中要求输入用户名和密码。 Therefore, how can I register a username and password so that I can enter the shiny APP?那么如何注册用户名和密码才能进入shiny APP呢？ Maybe use some php code along?也许使用一些 php 代码？ I know there are shiny packages that work with login and password, however, I would like to use an html page that I created myself to access the shiny app.我知道有 shiny 包可以使用登录名和密码，但是，我想使用我自己创建的 html 页面来访问 shiny 应用程序。

Shiny code Shiny代码

library(shiny)
ui <- fluidPage(
    

    sidebarLayout(
        sidebarPanel(
            
            sliderInput("bins",
                        "Number of bins:",
                        min = 1,
                        max = 50,
                        value = 30)
        ),

        mainPanel(
           plotOutput("distPlot")
        )
    )
)

server <- function(input, output) {

    output$distPlot <- renderPlot({
        x    <- faithful[, 2]
        bins <- seq(min(x), max(x), length.out = input$bins + 1)

        hist(x, breaks = bins, col = 'darkgray', border = 'white')
    })

}

shinyApp(ui = htmlTemplate("www/index.html"), server = server)

Answer 1

I recommend the shinymanager package ( https://datastorm-open.github.io/shinymanager/ ) as it does provide a good, reliable and (I guess) safe way to have a login-page for your app.我推荐shinymanager package（ https://datastorm-open.github.io/shinymanager/ ）因为它确实为您的应用程序提供了一个可靠的登录页面（我的猜测）。

You can even store the credentials in a small, local SQLite-database that again is password protected.您甚至可以将凭据存储在一个小型的本地 SQLite 数据库中，该数据库再次受密码保护。

It also comes with a simple administration panel as well as access-statistics.它还带有一个简单的管理面板以及访问统计信息。
