具有字符“."的Firebase数据库REST API URL出现问题.即周期 [英] Issue with Firebase database REST API URL having character "." i.e. period

问题描述

如果json树路径中的任何节点包含字符"，则Firebase无法存储数据.即周期

Firebase is not able to store data if any of the node in the json tree path contain character "." i.e period

示例

https://.firebaseio.com/path/to/node/.json 将数据存储在上面指定的json树节点中.

https://.firebaseio.com/path/to/node/.json Will store the data in above specified json tree node.

但是，请在下面的查询中考虑我有."的地方.我的网址中的字符

However, consider below query where I have a "." character in my url

https://.firebaseio.com/path/to/node.speical/.json

它将返回

{
"error": "Invalid path: Invalid token in path"
}

这是因为Firebase服务器没有适当处理这种情况吗? 请提出建议.

Is this something because firebase server have not handled this case appropriately?? Please suggest.

推荐答案

是的，Firebase的键中存在一组不支持的特殊字符.从Firebase文档-

Yes, there are a set of special characters that Firebase does not support in it's keys. From Firebase doc -

子节点的密钥不能超过768个字节，也不能大于32个字节 水平.它可以包含除以外的任何unicode字符. $#[]/ 和ASCII控制字符0-31和127.

A child node's key cannot be longer than 768 bytes, nor deeper than 32 levels. It can include any unicode characters except for . $ # [ ] / and ASCII control characters 0-31 and 127.

如果密钥中存在这些字符，则需要对这些字符进行转义或编码.一个简单的字符替换编码也将起作用.

You need to escape or encode those characters if they are present in your key. A simple character substitution encoding will work too.
