java - JSON解析错误: Unexpected character (s) at position 226025

Question

我在 Stackoverflow 上看到了类似的问题，但没有一个能帮助我解决我的问题。因此，我寻求帮助，因为我试图找出我收到的错误背后的原因，但失败了。请不要将其标记为重复问题。

我正在解析 Json 文件并收到以下错误。

} catch (IOException | ParseException ex) {
    Logger.getLogger(FileManager.class.getName()).log(Level.SEVERE, null, ex);

我已经抓取了 500K 个网页并将它们存储在 Json 文件中。现在，我正在尝试阅读它。整个文件有2GB，所以我无法共享整个文件。

我知道 Json 解析器在文件中获取了一些意外字符 (s)，但我无法找到 json 文件中的哪一行是错误的。有什么办法可以找出json文件中的错误行吗？

编辑

处理网页内容的主要代码如下。

for (Element element : elements) {
    String tagName = element.tagName();
    if (Util.isValidTag(tagName)) {
        String textValue = Util.removeNonPrintableChars(element.ownText()).trim().replace("\"", "\'");
        if (!textValue.isEmpty()) {
            if (tagTextMap.containsKey(tagName)) {
                tagTextMap.get(tagName).add(textValue);
            } else {
                ArrayList<String> arr = new ArrayList<>();
                arr.add(textValue);
                tagTextMap.put(tagName, arr);
            }
        }
    }
}

我刚刚删除了不可打印的字符，并将双引号替换为单引号，就是这样。

更新

我在 json 文件中找到了有问题的部分。

{
    "url": "http://www.kudzu.com/",
    "title": "Atlanta roofers, hvac, plumbers, electricians and other businesses - reviews, coupons and cost estimates from your neighbors.",
    "content": {
        "h2": ["From Our Experts", "Recent Projects", "Recent Articles", "What It Costs", "Review a Business", "What It Costs", "Other Markets"],
        "body": ["\"],
        "span": ["Area", "Area", "Cost"]
    }
}

这部分 - "body": ["\"], 是问题的根源。我现在可以理解为什么它会导致问题。

Answer 1

您似乎在转义特殊字符时遇到问题。请参阅 JSON 中使用的特殊字符列表:

1. \b 退格键(ascii 代码 08)
2. \f 换页(ascii 代码 0C)
3. \n 新行
4. \r 回车
5. \t 制表符
6. \"双引号
7. \反斜杠字符

因此，在转储 json 时，您需要转义这些特殊字符。幸运的是，每个 json 库都有办法完成这项工作。由于您似乎已经使用了 JSON.simple 工具包，因此您可以使用 JSONObject.escape()转义特殊字符的方法。
