问题描述
我正在尝试使用利用sf软件包的plumber软件包创建一个API。以下函数获取加利福尼亚某个位置的x / y坐标，并使用sf :: st_intersects函数检查坐标所属的电商区域。当我在R会话中以交互方式运行它时，但是当我使用水管工进行部署时，该函数有效
edu_mapping <- function(x,y) {
st_read_edu <- sf::st_read('https://services3.arcgis.com/bWPjFyq029ChCGur/arcgis/rest/services/California_Electric_Utility_Service_Areas/FeatureServer/0/query?where=1%3D1&objectIds=&time=&geometry=&geometryType=esriGeometryEnvelope&inSR=&spatialRel=esriSpatialRelIntersects&resultType=none&distance=0.0&units=esriSRUnit_Meter&returnGeodetic=false&outFields=*&returnGeometry=true&returnCentroid=false&featureEncoding=esriDefault&multipatchOption=xyFootprint&maxAllowableOffset=&geometryPrecision=&outSR=&datumTransformation=&applyVCSProjection=false&returnIdsOnly=false&returnUniqueIdsOnly=false&returnCountOnly=false&returnExtentOnly=false&returnQueryGeometry=false&returndistinctValues=false&cacheHint=false&orderByFields=&groupByFieldsForStatistics=&outStatistics=&having=&resultOffset=&resultRecordCount=&returnZ=false&returnM=false&returnExceededLimitFeatures=true&quantizationParameters=&sqlFormat=none&f=pgeojson&token=')
points <- data.frame(x = x,y = y)
points_sf <- sf::st_as_sf(points,coords = c('x','y'),crs = 4326)
intersection <- sf::st_intersects(st_read_edu,points_sf,sparse = FALSE) %>%
as.data.frame() %>%
dplyr::mutate(edu = st_read_edu$Utility) %>%
dplyr::rename(within_edu_territory = V1) %>%
filter(within_edu_territory == TRUE)
return(intersection)
}
edu_mapping(x = -118.240290,y = 34.072580)
within_edu_territory edu
1 TRUE Los Angeles Department of Water & Power
但是，当我在api中运行相同的代码时，我没有得到任何返回值，因为inside_edu_territory的所有值都返回false：

似乎正在发生的事情是，points_sf对象应返回（-118.2403 34.07258）的几何，而在管道工API中返回的值为（1,1）。
我在启动后在本地调用它，就像这样：
root <- plumber::pr("plumber_test_r_file.R")
root %>%
plumber::pr_run()
这是我在浏览器中的呼叫：
http://127.0.0.1:5595/intersection?x=-118.240290&y=34.072580
它正在比较每个x / y的多边形的几何形状似乎在检查相交之前已正确设置格式，对于points_sf来说似乎有点奇怪，因为x / y的几何形状被弄乱了。 / p>
为什么会这样？
我的管道工文件和会话信息如下：
#' Check which EDU territory encompasses an address
#' @param x longitude of the location
#' @param y latitude of the location
#' @get /intersection
#' @serializer json
function(x,y) {
