我们可以在Firebase数据库中将电子邮件ID作为密钥吗? [英] Can we have Email Id as key in Firebase database?
问题描述
我想创建一个登录系统，当用户登录时，基于 在登录用户的电子邮件ID上，我想检索EID.
I want to create a login system , when the user logs in, based on the logged in users email id, I want to retrieve the EID.
我想要的JSON结构是:
The JSON structure I want is:
{
"joel@dept.com":
{
"EID":"0153"
},
"Stan@dept.com":
{
"EID":"0163"
}
}
我尝试将具有上述结构的JSON文件导入Firebase项目数据库，但是出现错误提示"./..."不能成为密钥的一部分.
I tried importing the JSON file with above structure into the Firebase projects database, but got an error suggesting "./ ..." cannot be a part of key.
推荐答案
用一个字符替换另一个字符可能会导致混乱，并可能在将来引起严重问题.
Replacing one character with another may lead to confusion and may cause critical issues in future.
对于该实例，暂时可以将.替换为_DOT_.以后说您要取回原始电子邮件以进行验证； [没关系]我可以将_DOT_替换为..如果有人收到电子邮件actual._DOT_@actualdot.com
For the instance, replacing . with _DOT_ may work for now. Say in future you want to get back the original email for some verification; [no big deal] I can replace _DOT_ back with .. This fails if someone has the email actual._DOT_@actualdot.com
解决方案是使用电子邮件哈希.我现在更喜欢md5.
The solution is to use email hash. I prefer md5 at the moment.
因此结构应为:
{
"<md5 hash of 'joel@dept.com'>": {
"EID":"0153"
},
"<md5 hash of 'Stan@dept.com'>": {
"EID":"0163"
}
}
