    $json_text = encode_json $perl_scalar
Converts the given Perl data structure to a UTF-8 encoded, binary string.

  decode_json  
  
    $perl_scalar = decode_json $json_text  
The opposite of encode_json: expects an UTF-8 (binary) string and tries to parse that as an UTF-8 encoded JSON text, returning the resulting referenc.


和encode_json相反,期望一个UTF-8 2进制字符串和尝试解析一个UTF-8编码的JSON 文本,返回一个结果的参考
