JSON :: ParserError:757:'{ [英] JSON::ParserError: 757: unexpected token at '{

问题描述

当前哈希为

{\"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散列，例如

now I need to convert it in proper hash like

{"report_name" => "Study/Control: ABIRATERONE ACETATE - 20151413355"}

所以我试图用JSON.parse来获取它，但是却出现了类似的错误:

so I am trying to get it with JSON.parse but I am getting error like:

JSON::ParserError: 757: unexpected token at '{

所以，如果有人知道这一点，请帮助我. 我正在使用Rails 3.2

So if someone know about that so please help me. and I am using Rails 3.2

推荐答案

您拥有的是打印为String的哈希.要将其转换为哈希，请使用评估.

What you have is a hash printed as String. To convert it into a Hash use 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}"
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，因此在非JSON字符串上使用JSON.parse时会得到JSON::ParserError:

PS: A JSON string should look as follows, meaning what you have is not JSON and hence you got JSON::ParserError for using JSON.parse on a non-JSON string :

"{\"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}"
