重点是这句

{“type”:“token_mgr_error”,“reason”:“token_mgr_error: Lexical error at line 1, column 5. Encountered: after : “””}

我们在查询的时候包含特殊字符：“”

所以为了避免搜索出错，我们需要对查询的字符串先进行转义文章来源地址https://www.toymoban.com/news/detail-591269.html

public static String escape(String s) {
        StringBuilder sb = new StringBuilder();
        for (int i = 0; i < s.length(); i++) {
            char c = s.charAt(i);
            if (c == '\\' || c == '+' || c == '-' || c == '!' || c == '(' || c == ')' || c == ':'
                    || c == '^' || c == '[' || c == ']' || c == '\"' || c == '{' || c == '}' || c == '~'
                    || c == '*' || c == '?' || c == '|' || c == '&' || c == '/') {
                sb.append('\\');
            }
            sb.append(c);
        }
        return sb.toString();
    }
