JSON中的空格字符是否无关紧要? [英] Are whitespace characters insignificant in JSON?

问题描述

json字符串中是否忽略空格，制表符和回车符等空白字符?

Are blank characters like spaces, tabs and carriage returns ignored in json strings?

例如，{"a":"b"}是否等于{"a" : "b"}?

推荐答案

是的，在语法中会忽略双引号字符串文字之外的空格.具体来说， RFC 4627 中JSON语法中的ws生成显示:

Yes, blanks outside a double-quoted string literal are ignored in the syntax. Specifically, the ws production in the JSON grammar in RFC 4627 shows:

Insignificant whitespace is allowed before or after any of the six
structural characters.

   ws = *(
             %x20 /              ; Space
             %x09 /              ; Horizontal tab
             %x0A /              ; Line feed or New line
             %x0D                ; Carriage return
         )
