Ruby to_json问题，错误为“非法/格式错误的utf-8"； [英] Ruby to_json issue with error "illegal/malformed utf-8"

问题描述

尝试将哈希转换为json字符串时出现错误JSON::GeneratorError: source sequence is illegal/malformed utf-8.我想知道这是否与编码有关，如何使to_json照原样处理\ xAE?

I got an error JSON::GeneratorError: source sequence is illegal/malformed utf-8 when trying to convert a hash into json string. I am wondering if this has anything to do with encoding, and how can I make to_json just treat \xAE as it is?

$ irb
2.0.0-p247 :001 > require 'json'
=> true
2.0.0-p247 :002 > a = {"description"=> "iPhone\xAE"}
=> {"description"=>"iPhone\xAE"}
2.0.0-p247 :003 > a.to_json
JSON::GeneratorError: source sequence is illegal/malformed utf-8
  from (irb):3:in `to_json'
  from (irb):3
  from /Users/cchen21/.rvm/rubies/ruby-2.0.0-p247/bin/irb:16:in `<main>'

推荐答案

\xAE在UTF-8中不是有效字符，您必须使用\u00AE代替:

\xAE is not a valid character in UTF-8, you have to use \u00AE instead:

"iPhone\u00AE"
#=> "iPhone®"

或相应地进行转换:

"iPhone\xAE".force_encoding("ISO-8859-1").encode("UTF-8")
#=> "iPhone®"
