r - Shiny 的服务器 session 超时不起作用

Question

我在 Linux 服务器上部署了一个 Shiny 的应用程序。如果一分钟没有事件，我希望应用程序超时。根据我阅读的内容，我将 app_idle_timeout 行添加到了 Shiny-server.conf 文件中，但我注意到它不起作用。有人可以建议我如何确保 session 在一分钟后超时吗？注意:我没有 Shiny 的服务器 PRO。

下面是我的 Shiny-server.conf 的样子。

Instruct Shiny Server to run applications as the user "shiny"
run_as shiny;

# Define a server that listens on port 3838
server {
  listen 3838;

  # Define a location at the base URL
  location / {

    # Host the directory of Shiny Apps stored in this directory
    site_dir /srv/shiny-server;

    # Log all Shiny output to files in this directory
    log_dir /var/log/shiny-server;
    app_idle_timeout 60;

    # When a user visits the base URL rather than a particular application,
    # an index of the applications available in this directory will be shown.
    directory_index on;

  }
}

您可以配置您的 idle内时间shiny像这样使用一些 JS 的应用程序，这里应用程序将在 5 秒后超时。

library(shiny)
library(leaflet)

inactivity <- "function idleTimer() {
  var t = setTimeout(logout, 5000);
  window.onmousemove = resetTimer; // catches mouse movements
  window.onmousedown = resetTimer; // catches mouse movements
  window.onclick = resetTimer;     // catches mouse clicks
  window.onscroll = resetTimer;    // catches scrolling
  window.onkeypress = resetTimer;  //catches keyboard actions

  function logout() {
    window.close();  //close the window
  }

  function resetTimer() {
    clearTimeout(t);
    t = setTimeout(logout, 5000);  // time is in milliseconds (1000 is 1 second)
  }
}
idleTimer();"


ui <- fluidPage(
  tags$script(inactivity),    
  leafletOutput("mymap")

)

server <- shinyServer(function(input,output,session){

  points <- eventReactive(input$recalc, {
    cbind(rnorm(40) * 2 + 13, rnorm(40) + 48)
  }, ignoreNULL = FALSE)

  output$mymap <- renderLeaflet({
    leaflet() %>%
      addProviderTiles(providers$Stamen.TonerLite,options = providerTileOptions(noWrap = TRUE)) %>% 
      addMarkers(data = points())
  })

})
runApp(list(ui = ui, server = server))
