我尝试在 R 中使用 API、应用程序/json，但是当我使用此代码时：


data <- fromJSON(content(XXX, type = "text"))

我看到下一个错误

Error: lexical error: invalid char in json text.
                      Producto;IdCompra;VentaN;
                     (right here) ------^

可能是什么问题？我知道我必须提取的数据是一个用“;”分隔的 csv 文件。

谢谢！

我在下面留下了我的数据的一瞥

您尝试读取的数据不是 json 格式，因此无法使用fromJSON. 它似乎是分号分隔的格式，所以也许试试

read.table(text = content(XXX, type = "text"), sep = ";", headers = TRUE)
