我正在尝试在线创建一个闪亮的应用plotGoogleMap
。
本地应用程序运行正常,但通过shinyapps
上传到shinyapps.io时,.html地图无法加载。
任何想法如何解决这个问题?
请参阅下面的代码。
ui.R
library('markdown')
library('shiny')
shinyUI(navbarPage("plotGooleMaps in shinyapps",
mainPanel(uiOutput('mymap'))
)
)
server.R
library('shiny')
library('plotGoogleMaps')
shinyServer(function(input, output){
output$mymap <- renderUI({
data(meuse)
coordinates(meuse) = ~x+y
proj4string(meuse) <- CRS("+init=epsg:28992")
m <- plotGoogleMaps(meuse, filename = 'myMap1.html', openMap = F)
tags$iframe(
srcdoc = paste(readLines('myMap1.html'), collapse = '\n'),
width = "900Px",
height = "500Px"
)
})
})
使用 shinyapps
部署应用
library('shinyapps')
setwd("~/working directory where ui.R and server.R are located locally")
deployApp()
这是错误日志,但我不知道从中得出什么结论:
[blocked] The page at 'about:srcdoc' was loaded over HTTPS, but ran
insecure content from 'http://maps.google.com/maps/api/js?sensor=false':
this content should also be loaded over HTTPS. about:srcdoc:1

答案 0 :(得分:0)
shinyapps论坛上有人解决了我的问题。 http
需要在地图文件中替换为https
。
Codewise,这意味着:
readLines('myMap1.html')
需要替换为
gsub("http://maps.google.com/",
"https://maps.google.com/",
readLines('myMap1.html'),
fixed=TRUE)
我还联系了作者,以便在plotGoogleMaps
包的下一次更新中解决此问题。
请注意,图例不起作用,但似乎是another issue
