java - net.sf.json.JSONException异常

Question

我转换了一个普通的 JavaScript array(在一个 JSP 页面中)，对该数组执行了一个 JSON.stringify() 并将其传递给另一个 JSP 作为一个参数。在另一个 JSP 中，我使用 request.getParameter() 读取它。

现在，在将字符串转换为 JSONArray 时，我遇到了这样的异常-

net.sf.json.JSONException: Missing value. at character 2 of [[\"111\", \"1.1.1.1\", \"111\", \"111\", \"111\"]]

这就是我的来自 request.getParameter() 的字符串的样子-

[[\"111\", \"1.1.1.1\", \"111\", \"111\", \"111\"]]

什么是 net.sf.json.JSONException:缺少值。在 [[\"111\",\"1.1.1.1\",\"111\",\"111\",\"111\"]] 的字符 2 是什么意思？我该如何处理？

Answer 1

我想通了。它抛出该异常的原因是因为它在 [[ 之后期望 " 而不是 \"。我所做的只是 [[\"111\",\"1.1.1.1\",\"111\",\"111\",\"111\"]].replaceAll("\\\"", "\"").
