Firebase规则保存失败：第6行预期'}'，请求排查问题

你的Firebase Realtime Database规则结构完全不符合语法要求：所有数据路径（users、usersWipes、user-messages等）的规则配置必须嵌套在顶级的"rules"对象内部，而不是和"rules"平级放在根JSON对象里。

原代码中，解析器执行到第5行的}时，会认为根对象已经结束，结果第6行又出现"users": {，直接触发语法错误，这就是报错"Line 6: Expected '}'"的原因。

修正后的规则代码 #

{
  "rules": {
    ".read": "auth.uid != null",
    ".write": "auth.uid != null",
    "users": {
      "$uid": {
        ".read": "auth.uid != null",
        ".write": "auth != null && auth.uid == $uid"
      }
    },
    "usersWipes" : {
      "$uid": {
        ".read": "auth.uid != null",
        ".write": "auth != null && auth.uid == $uid"
      }
    },
    "user-messages": {
      "$uid": {
        ".read": "auth.uid != null",
        ".write": "auth != null && auth.uid == $uid"
      }
    },
    "stripe_customers": {
      "$uid": {
        ".read": "auth != null && auth.uid == $uid",
        ".write": "auth != null && auth.uid == $uid"
      }
    },
    "notifications": {
      "$uid": {
        ".read": "auth != null",
        ".write": "auth != null && auth.uid == $uid"
      }
    },
    "messages": {
      "$uid": {
        ".read": "auth != null",
        ".write": "auth != null && auth.uid == $uid"
      }
    },
    "jobPost": {
      "$uid": {
        ".read": "auth != null",
        ".write": "auth != null"
      }
    },
    "reportedJobs": {
      "$uid": {
        ".read": "auth != null && auth.uid == $uid",
        ".write": "auth != null"
      }
    },
    "deletedAccounts": {
      "$uid": {
        ".write": "auth != null && auth.uid == $uid"
      }
    }
