JSON语法错误：“object中属性值后的”意外数字“或”JSON.parse:预期“、”或“}”

Question

我使用$.ajax()接收来自POST请求的响应：

{"command": 6,"log_size":50,"log":[
    {"type": 30,"tag": "*NETEVENT*","sensors": "0D","ti": 1047161877,"to": 0},
    {"type": 30,"tag": " __START__","sensors": "00","ti": 0000011410,"to": 0},
    {"type": 30,"tag": "*NETEVENT*","sensors": "0A","ti": 0000011411,"to": 0},

    {"type": 30,"tag": " __START__","sensors": "00","ti": 1047215799,"to": 0},
    {"type": 30,"tag": "*NETEVENT*","sensors": "0A","ti": 1047215799,"to": 0},
    {"type": 30,"tag": " __START__","sensors": "00","ti": 1047218051,"to": 0},
    {"type": 30,"tag": "*NETEVENT*","sensors": "0D","ti": 0000002598,"to": 0},

    {"type": 30,"tag": "*NETEVENT*","sensors": "0D","ti": 1047071225,"to": 0},
    {"type": 30,"tag": "*NETEVENT*","sensors": "0A","ti": 0000000010,"to": 0},

    {"type": 30,"tag": "*NETEVENT*","sensors": "0A","ti": 0000000180,"to": 0},
    {"type": 30,"tag": "*NETEVENT*","sensors": "0B","ti": 0000000206,"to": 0},
    {"type": 30,"tag": "*NETEVENT*","sensors": "09","ti": 0000000212,"to": 0},
    {"type": 30,"tag": "*NETEVENT*","sensors": "08","ti": 0000000383,"to": 0},
    {"type": 30,"tag": " __START__","sensors": "00","ti": 0000001562,"to": 0},
    {"type": 30,"tag": "*NETEVENT*","sensors": "0A","ti": 0000001563,"to": 0},
    {"type": 30,"tag": "*NETEVENT*","sensors": "0B","ti": 0000001564,"to": 0},
    {"type": 30,"tag": "*NETEVENT*","sensors": "0D","ti": 1047161632,"to": 0},
    {"type": 30,"tag": " __START__","sensors": "00","ti": 1047161875,"to": 0},
    {"type": 30,"tag": "*NETEVENT*","sensors": "0B","ti": 1047161876,"to": 0}
],
"response":"ok"}

对于IE运行良好，在Chrome中显示为"Syntax error: unexpected number"，在火狐中消息为"SyntaxError: JSON.parse: expected ',' or '}' after property value in object"

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

知道为什么会这样吗？

Answer 1

一个数字不能以没有意义的0开头。

此操作无效："ti": 0000011410

来自JSON.org：

​

​

您应该在源端修复它，但是如果不能，假设您的总是类似于这个(没有字符串中的数字)，那么您可能会用正则表达式来修复它：

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

您甚至不能在这里使用邪恶的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在JSON中禁止以无意义的0开头的数字更安全。

Answer 2

在json中的数字前面删除0。
