EXPO Apple登录响应本机返回空值

如何解决EXPO Apple登录响应本机返回空值

我已使用我的react本机应用程序中实现的apple登录。有时候它有时会起作用。

当它不工作时，将返回所有空用户值，如下所示：

{
  "authorizationCode": "123456789omitted","email": null,"fullName": Object {
    "familyName": null,"givenname": null,"middleName": null,"namePrefix": null,"nameSuffix": null,"nickname": null,},"identityToken": "987654321omitted","realUserStatus": 1,"state": null,"user": "192837465omitted",}

为什么会这样？

<AppleAuthentication.AppleAuthenticationButton
  buttonType={AppleAuthentication.AppleAuthenticationButtonType.SIGN_IN}
  buttonStyle={AppleAuthentication.AppleAuthenticationButtonStyle.BLACK}
  cornerRadius={5}
  style={{
    width: Constant.width * 0.92,height: 44,}}
  onPress={async () => {
    try {
      setAppleLoggingIn(true);
      const credential = await AppleAuthentication.signInAsync({
        requestedScopes: [
          AppleAuthentication.AppleAuthenticationScope.FULL_NAME,AppleAuthentication.AppleAuthenticationScope.EMAIL,],});
      // signed in
      onSignIn(credential);//signs in user via firebase
      setAppleLoggingIn(false);
    } catch (e) {
      if (e.code === "ERR_CANCELED") {
        // handle that the user canceled the sign-in flow
        setAppleLoggingIn(false);
        return {cancelled: true};
      } else {
        // handle other errors
        setAppleLoggingIn(false);
        return {error: true};
      }
    }
  }}
/>

我认为这与这个问题有关，但我从未阻止过该应用程序访问我的Apple ID ...在请求权限时，我总是“接受”。 Getting email id value null as response during apple-authentication

解决方法

Apple登录仅发送有关第一个登录（注册）的用户信息。之后，由您决定存储这些信息并在用户再次登录时重新使用它们。
