ios - Firebase 和 iOS : FIRAuthInternalErrorDomain "MISSING_IDENTIFIER" when trying to login with custom token

Question

我最近迁移到了新版本的 Firebase。我在我的 iOS 应用程序中使用新的 SDK。

我使用的是 Firebase 3.2.0，并且在使用自定义 token 登录时遇到以下错误:

Optional(Error Domain=FIRAuthErrorDomain Code=17999 "An internal error has occurred, print and inspect the error details for more information." UserInfo={NSUnderlyingError=0x7fd290f3dc50 {Error Domain=FIRAuthInternalErrorDomain Code=3 "(null)" UserInfo={FIRAuthErrorUserInfoDeserializedResponseKey=<CFBasicHash 0x7fd2931787a0 [0x10e5db7b0]>{type = immutable dict, count = 3,

entries =>

0 : <CFString 0x7fd2931669b0 [0x10e5db7b0]>{contents = "message"} = <CFString 0x7fd29318e280 [0x10e5db7b0]>{contents = "MISSING_IDENTIFIER"}

1 : errors = <CFArray 0x7fd2931554b0 [0x10e5db7b0]>{type = immutable, count = 1, values = (

0 : <CFBasicHash 0x7fd293141000 [0x10e5db7b0]>{type = immutable dict, count = 3,

entries =>

0 : reason = invalid

1 : message = <CFString 0x7fd2931a0070 [0x10e5db7b0]>{contents = "MISSING_IDENTIFIER"}

2 : domain = global

}



)}

2 : code = <CFNumber 0xb000000000001903 [0x10e5db7b0]>{value = +400, type = kCFNumberSInt64Type}

}

}}, error_name=ERROR_INTERNAL_ERROR, NSLocalizedDescription=An internal error has occurred, print and inspect the error details for more information.})

我不知道“MISSING_IDENTIFIER”是什么意思。

有人有同样的问题吗？

Answer 1

我解决了这个问题。 当服务器生成自定义 token 时，“uid”的值是必需的。 “IDENTIFIER”表示值“uid”。

Generate Custom Token

$payload = array(
      "iss" => $service_account_email,
      "sub" => $service_account_email,
      "aud" => "https://identitytoolkit.googleapis.com/google.identity.identitytoolkit.v1.IdentityToolkit",
      "iat" => $now_seconds,
      "exp" => $now_seconds+(60*60),  // Maximum expiration time is one hour
      "uid" => $uid,
      "claims" => array(
          "premium_account" => $is_premium_account
      );
