我正在尝试解析一些包含随机 JSON 的 CSV。JSON 有双引号：

csv = CSV.parse('example,json=[{"json": "obj"}],endexample')
CSV::MalformedCSVError: Illegal quoting in line 1.
  from /Users/kevzettler/.rbenv/versions/1.9.3-p194/lib/ruby/1.9.1/csv.rb:1925:in `block (2 levels) in shift'
  from /Users/kevzettler/.rbenv/versions/1.9.3-p194/lib/ruby/1.9.1/csv.rb:1887:in `each'
  from /Users/kevzettler/.rbenv/versions/1.9.3-p194/lib/ruby/1.9.1/csv.rb:1887:in `block in shift'

  from (irb):13

我已经读到在 CSV 中你在引号中转义了一个引号，所以我尝试了类似的东西.gsub('"','""')，但这并没有帮助。

csv = CSV.parse('example,json=[{""json"": ""obj""}],endexample')

来自关于 CSV 的维基百科：

  • 应引用包含换行符、双引号和/或逗号的字段。（如果不是，则文件可能无法正确处理）。
  • 字段中的（双）引号字符必须由两个（双）引号字符表示。

尝试这个：

csv = CSV.parse('example,"json=[{""json"": ""obj""}]",endexample')
