将JSON字符串转换为Rails哈希表

Question

我正在使用Rails 2.3版本，尝试将一个JSON格式的字符串转换为Rails哈希表。然而，当我使用JSON.parse时，得到的JSON字符串没有分隔符：

{"source_id":40007,"object":"86088947610496.1","coursewalk_id":"86088947610477.1","description":"","image_uri":"db\/db-files\/
Image_2011-09-24_14.37.37__0000.jpg","latitude":"38.0113439821061","letter":"","letter_A":"","letter_B":"","letter_C":"","lett
er_D":"","letter_E":"","letter_F":"","longitude":"-78.7576854509104","number":"1","mcw_id":71}

< p > JSON.parse 的结果:

代码：

puts string_to_parse
fence_parsed = JSON.parse(string_to_parse)
puts fence_parsed

有什么想法吗？

谢谢， Nick

您可以检查一下 fence_parsed 变量的类吗？"puts fence_parsed.class" - Sergey Kuznetsov

Answer 1

这是因为您使用了 "puts"。如果您只键入 fence_parsed 或 p fence_parsed，您将得到您要查找的内容。puts 调用 to_s。希望这能为您澄清问题，如果不能，请告诉我，我会详细说明。
