Question

我正在尝试解析其中包含一些随机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 /Users/kevzettler/.rbenv/versions/1.9.3-p194/lib/ruby/1.9.1/csv.rb:1849:in `loop'
  from /Users/kevzettler/.rbenv/versions/1.9.3-p194/lib/ruby/1.9.1/csv.rb:1849:in `shift'

  from (irb):13
  from /Users/kevzettler/.rbenv/versions/1.9.3-p194/bin/irb:12:in `<main>'

我已经在CSV中看到你在引号内转义引号所以我尝试了类似.gsub('"','""')的内容，但是这没有帮助。

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

来自Wikipedia关于CSV：

包含换行符，双引号和/或逗号的字段应为引。（如果不是，则可能无法使用该文件正确处理）。
字段中的（双）引号字符必须是用两个（双）引号字符表示。

试试这个：

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