jsonlite 包无法使用 ANSI 编码导入文件

Question

我试图在 R 中导入一个 json 文件（下载的文件编码是 ANSI。），但出现以下错误：

> library(jsonlite)
> js <- url %>% 
+   read_html() %>%
+   html_text() 
> js <- jsonlite::fromJSON(js)
Error: lexical error: invalid bytes in UTF8 string.
          _name": "Av. Nossa Sra. de Fátima , 25",             "stop_i
                     (right here) ------^

可重现的例子：

url <- "https://jeap.rio.rj.gov.br/MOB/get_stops_details.rule?sys=MOB&INDICE=1"

library(rvest)
library(jsonlite)

js <- url %>% 
  read_html() %>%
  html_text() 

js <- jsonlite::fromJSON(js)

Answer 1

在 read_html

中设置正确的编码

library(rvest)
library(jsonlite)

js <- url %>% 
  read_html(encoding = 'latin1') %>%
  html_text() 

js <- jsonlite::fromJSON(js)
