JSON语法错误:'意外数字'或'JSON.parse:expected','或'}'在对象'中的属性值之后

Question

我使用$ .ajax()从POST请求收到此响应:

    {"type": 30,"tag": "*NETEVENT*","sensors": "0B","ti": 1047161876,"to": 0}
],
"response":"ok"}

对于IE工作正常,在Chrome中出现"Syntax error: unexpected number"并在Firefox中显示消息"SyntaxError: JSON.parse: expected ',' or '}' after property value in object"

在各种在线JSON解析器和验证器中,响应的格式似乎没问题,但在firefox和chrome中不起作用.

知道为什么会这样吗？

一个数字不能以一个没有意义的开头0.

这是无效的: "ti": 0000011410

来自JSON.org:

你应该在源代码修复它,但如果你不能,假设你的JSON总是类似于这个(字符串中没有数字),那么你可能用正则表达式修复它:

var obj = JSON.parse(str.replace(/ 0+(?![\. }])/g, ' '));

你甚至不能在这里使用邪恶eval因为"0000011410"将被解析为八进制:

console.log(eval('({"ti": 0000011410})'));

输出

{ti: 4872}

这可能解释了为什么禁止0以JSON中的非重要性开头的数字更安全.
