如何使用「隐藏 JSON 字符串内容」？How do I use the Hide JSON Strings tool?

键名会藏吗？Are keys hidden?
不会，只替换字符串类型的值；数字、布尔和 null 原样保留（大整数也不会变）。No — only string values are replaced; numbers, booleans and null stay exactly as written (big integers too).
大数字和重复键会怎样？What about big numbers and duplicate keys?
数字按原文保留，不经过 JavaScript 浮点：12345678901234567890、1e400、1.50 原样输出，不会变成 12345678901234567000、Infinity 或 1.5。重复的键按 JSON 规则保留最后一个值，并在结果下方提示是哪个键。语法错误会写出第几行第几列。Numbers are kept exactly as written, with no JavaScript floating-point step: 12345678901234567890, 1e400 and 1.50 come out unchanged instead of 12345678901234567000, Infinity or 1.5. Duplicate keys keep the last value, as JSON parsers do, and a notice below the result names the key. Syntax errors give the line and column.
