我已抓取500K网页并将其存储在Json文件中。现在，我正在尝试阅读它。整个文件是2GB，所以我无法共享整个文件。
我理解Json解析器在文件中获得了一些意外的字符(s)，但我无法找到json文件中的哪一行是错误的。有什么方法可以找出json文件中的错误行吗？
修改
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);
}
}
}
}
我刚删除了不可打印的字符，并用单引号替换双引号，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"]
}
}
此部分 - "body": ["\"],是问题的根源。我现在能理解为什么会导致这个问题。
答案 0 :(得分：1)
您似乎无法转义特殊字符。请参阅JSON中使用的特殊字符列表：
所以，在转储json时你需要转义这个特殊字符。幸运的是，每个json图书馆都有办法完成这项工作。由于您似乎使用了JSON.simple工具包，因此可以使用JSONObject.escape()方法来转义特殊字符。
