导读：当前的哈希是 {"report_name"="Study/Control: ABIRATERONE ACETATE - 20151413355","left_mue_start_date"="02-26-2015","left_mue_end_date"="03-19-2015","right_mue_start_date"="02-26-2015","right_mue_end_date"="03-19-2015","

当前的哈希是
{"report_name"=>"Study/Control: ABIRATERONE ACETATE - 20151413355","left_mue_start_date"=>"02-26-2015","left_mue_end_date"=>"03-19-2015","right_mue_start_date"=>"02-26-2015","right_mue_end_date"=>"03-19-2015","report_formulary_id"=>",7581","mue"=>"true","mue_type"=>"study/control","chain_id"=>"1","left_mue_formulary_ids"=>["7581"],"action"=>"create_report","controller"=>"informatics","user_id"=>339}
现在我需要将其转换为适当的哈希值 {"report_name" => "Study/Control: ABIRATERONE ACETATE - 20151413355"}
所以我试图用JSON.parse得到它,但我得到的错误如下： JSON::ParserError: 757: unexpected token at '{
所以,如果有人知道这一点,请帮助我. 解决方法
你有一个打印为String的哈希.要将其转换为Hash,请使用
eval.
ch = "{"report_name"=>"Study/Control: ABIRATERONE ACETATE - 20151413355","user_id"=>339}"
hash = eval(ch)
# => {"report_name"=>"Study/Control: ABIRATERONE ACETATE - 20151413355","left_mue_start_date"=>"02-26-2015","left_mue_end_date"=>"03-19-2015","right_mue_start_date"=>"02-26-2015","right_mue_end_date"=>"03-19-2015","report_formulary_id"=>",7581","mue"=>"true","mue_type"=>"study/control","chain_id"=>"1","left_mue_formulary_ids"=>["7581"],"action"=>"create_report","controller"=>"informatics","user_id"=>339}
PS：JSON字符串应如下所示,这意味着您拥有的不是JSON,因此您在非JSON字符串上使用JSON.parse时获得了JSON :: ParserError： "{"report_name":"Study/Control: ABIRATERONE ACETATE - 20151413355","left_mue_start_date":"02-26-2015","left_mue_end_date":"03-19-2015","right_mue_start_date":"02-26-2015","right_mue_end_date":"03-19-2015","report_formulary_id":","mue":"true","mue_type":"study/control","chain_id":"1","left_mue_formulary_ids":["7581"],"action":"create_report","controller":"informatics","user_id":339}"
