    FastJson 包： 原始对象：M 里面数据类似

    face_data 字段值： ["AwMBAAABAAAKFDWQmQUdGj...xUS7GnoKZ5vidnh4nBXUynG/dkZHiyC578BGWWcy+WAVMaL3WxJ/Xk1fqejpgz7DpgNMmGkh\nvUOjtqwe\n"]"

    String json = JSON.toJSONString(M, SerializerFeature.DisableCheckSpecialChar);

    但是转换后，[后面的那个双引号"还是被多加上了转义反斜线\；

    "face_data":"[\"AwMBAAABAAAKFDWQmQUdGj...xUS7GnoKZ5vidnh4nBXUynG/dkZHiyC578BGWWcy+WAVMaL3WxJ/Xk1fqejpgz7DpgNMmGkh\nvUOjtqwe\n\"]"

    SerializerFeature.DisableCheckSpecialChar 这个代码无效

    ==========================
    请大侠帮忙

    JSON 标准了解一下，前开后闭，加反斜杠解析的时候才正常，又不是人复制粘贴

    你写代码也不能这么写吧 String s = "akam"aa"";

    @lhx2008 这个用 JSON.toJSONString()将对象序列化为字符串，默认是将特殊字符"转义的，我是说能配置，让它忽略特殊字符"吗

    @BernardMe 这个特性不知道源代码里面有没有写文档说是什么意思，如果你确实要保留双引号，可以要求 FASTJSON 用单引号在外面。

    查了下 fastjson 文档，DisableCheckSpecialChar 已经被 Deprecated 了

    你的需求简单，建议手动处理下。

    其他方式参考 fastjson issue

    @zhaogaz 你是说这个方法 public String replaceAll(String regex, String replacement) 手动截取替换?
