【问题描述】：

CSV 文件，我正在阅读

"Customer","ID","Host name","Created","Status","OS","OS Version","RAM"
"XXX","1234","abcd","2021-12-10 12:43:09","Linux Server","RedHat RHEL82gen2","2,048"

这个 csv 文件的每一列都有"..."，RAM 列的值是, 我不会阅读这个 csv，它有双引号，并且它的列的值中有一个逗号（，）。

我尝试过使用quote_char: '"'

【问题讨论】：

你能发布关于你如何阅读它的 sn-p / 示例代码吗？还有你用什么图书馆？ Ruby 的标准 CSV 库允许配置列分隔符

标签： ruby csv

【解决方案1】：

" 是默认引号字符，, 是默认字段分隔符CSV.parse 可以按原样完美读取您的数据：

require 'csv'

data = <<-EOD
"Customer","ID","Host name","Created","Status","OS","OS Version","RAM"
"XXX","1234","abcd","2021-12-10 12:43:09","Linux Server","RedHat RHEL82gen2","2,048"
EOD

CSV.parse(data)
#=> [
#     ["Customer", "ID", "Host name", "Created", "Status", "OS", "OS Version", "RAM"],
#     ["XXX", "1234", "abcd", "2021-12-10 12:43:09", "Linux Server", "RedHat RHEL82gen2", "2,048"]
#   ]

注意最后一个值是"2,048"——逗号被正确解析。

谢谢。虽然它给了我输出，但我不希望“”在那里。期望结果是 Customer xxx ID 1234 Host name abcd Created 2021-12-10 12:43:09 OS Linux Server OS Version RedHat RHEL82gen2 RAM 2,048
@Shruthi 有引号是因为它是一个 Ruby 字符串，如果你 puts 的值你不会看到引号。
