尽管已授予所有权限，react-native fbsdk 仍返回未定义的电子邮件

Question

我正在尝试通过 facebook sdk 获取信息，但到目前为止我只获取用户的 ID 和名称。我确实已经授予许可，但电子邮件仍然像名称和 ID 一样弹出。我几乎什么都试过了。

如有任何帮助，我们将不胜感激。

提前致谢

           render() {
         return (
             <View>
             <TouchableOpacity onPress={() => this._fbAuth()}>
               <Text>  Press me</Text>

            </View>
        );
             }

                   }

result.email 不应未定义。

您可以直接使用 fbsdk 提供的 accessToken。只需获取 accessToken，一旦您收到 accessToken，您就可以使用 accessToken.[= 向 facebook 图 api 发出请求以接收与该用户相关的数据16=]

这是完整的文档，它还包括 accessToken。它会帮助你。我也是这样。
