Question

我有一个服务器：
ubuntu 16.04
nginix
乘客

我尝试使用send_data的方式发送文件，文件名是Cyrillic，但是当我收到（由于下载文件）而收到的文件名，则使用了错误的编码。
示例：
在服务器上：Сводный_отчет_по_СПК_имени_Куйбышева_за_25.04.2019г.xlsx
下载时：ÐÐÐ´。。。。。。。。。。。。¼¼¼。 Ð_ÐµÐ½Ð¸½½Ð°_Ð·Ð°_25.04.2019Ð³.xlsx

我的功能

send_data package.to_stream.read, type: 'application/xlsx', filename: "Сводный_отчет_по_#{name}_за_#{to_date}.xlsx"

Answer 1

尝试指定编码

n <- nrow(mtcars)

for (i in 1:n){
  cat("\n mtcars currently has",nrow(mtcars),"rows;","accessing row",i)
  if (mtcars$cyl[i] == 4){
    mtcars <- mtcars[-i,]
  }
}

> mtcars currently has 32 rows; accessing row 1
 mtcars currently has 32 rows; accessing row 2
 mtcars currently has 32 rows; accessing row 3
 mtcars currently has 31 rows; accessing row 4
 mtcars currently has 31 rows; accessing row 5
 mtcars currently has 31 rows; accessing row 6
 mtcars currently has 31 rows; accessing row 7

Error in if (mtcars$cyl[i] == 4) { : 
  missing value where TRUE/FALSE needed
