JSON 解析不可能，但 JSON Lint 说可以

Question

我正在使用 jquery 接收几行 javascript 并获取此 err

Unexpected token ILLEGA

这是我正在尝试解析的完整 json。 JSON Lint 不会抱怨...

Answer 1

您的 JSON 很好，所以显然您要求 jQuery 解析的内容与您引用的内容不一样，因为 jQuery 是 很高兴解析它。在该示例中，我通过 ajax 加载 JSON 文本。

如果您从 JavaScript string 读取 JSON 文本，而不是从某个地方加载它，例如：

var str = '{ ' +
          '"executionResult": "",' +
          '"outputText": "",' +
          '"stacktraceText": "..."' +
          '}';

...然后引用您要解析的实际字符串文字，我们可以告诉您有什么问题吗？但那个 JSON 没问题。

Answer 2

分配给 stacktraceText 的引号内的字符串值是问题所在。 JK的评论一针见血。

您显然正在尝试处理在某处收到的错误消息（异常），该消息不打算以您正在执行的方式进行解析。

如果您可以控制错误消息，则它在 JSON 通常预期的值对上下文中有意义。
