Question

当我尝试访问Docker容器外部时，我收到下面提到的错误的空数据。我对Docker容器中的curl和wget命令没有任何问题。容器基于Angular JS图像。

“localhost没有发送数据.ERR_EMPTY_RESPONSE”和“curl：（52）来自服务器的空回复”

请帮忙。

抱歉！忘了发布实际代码。这是我的Dockerfile和package.json文件。

的package.json

这样做的理想方法我建议在创建时将主机IP地址绑定到容器。您不应该从docker文件启动应用程序的运行。创建容器，与主机绑定并编写脚本以启动应用程序

你可以这样做，

ui <- function(id) {
  fluidPage(
    title = "Job Tracker",

    fluidRow(
      column(width=6,
             selectInput("pickvalue", label = "Pick a Value", choices = unique(iris$Species))
      )
    ),

    br(),
    fluidRow(
      column(12,
             DT::dataTableOutput("job_data")

      )

    ),
    br(),
    fluidRow(
      column(12,DT::dataTableOutput("x4"))
    )
  )

}

server <- function(input, output, session)
{
      output$job_data  <- DT::renderDataTable({
      datatable(iris[iris$Species==input$pickvalue,],selection = "single")
      })

    output$x4 <- DT::renderDataTable({
      s <- input$job_data_rows_selected
      datatable(iris[s,])
    })

}

“ 8553 ”可以是您的应用程序默认内部端口，其中包含“ 4545 ”外部端口

“localhost没有发送数据.ERR_EMPTY_RESPONSE”和“curl：（52）来自服务器的空回复”
