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

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();}
