Firestore支持的自定义ID字符 [英] Firestore supported characters for custom id's
问题描述
我想在Firestore中为我的文档创建自定义ID，我知道支持所有 base 62 ( az，AZ，0-9 )字符自定义ID，我需要了解Firestore支持在自定义ID中使用的特殊字符(-_ *& $#@！`〜％等)，是有不受支持的特殊字符吗?
I would like to create a custom id for my documents in firestore, I know all the base 62 (a-z, A-Z, 0-9) characters are supported for custom id's, I need to know about the special characters (- _ * & $ # @ ! ` ~ % etc) supported by firestore to use in custom id's, is there any unsupported special character?
也想了解空白情况，我可以创建一个像 abc 123 这样的自定义ID吗?
Also want to know about the white space case, can I create a custom id like abc 123 ?
推荐答案
这是一个很晚的答案，但由于我自己只是在寻找此信息:
This is a late answer, but as I was just looking for this information myself:
文档ID(和集合ID为)的约束为:
The constraints on the document ids (and collection ids are) are:
- 必须是有效的UTF-8字符
- 不得超过1,500个字节
- 不能包含正斜杠(/)
- 不能仅由一个句点(.)或两个句点(..)组成
- 无法匹配正则表达式
__.*__
- Must be valid UTF-8 characters
- Must be no longer than 1,500 bytes
- Cannot contain a forward slash (/)
- Cannot solely consist of a single period (.) or double periods (..)
- Cannot match the regular expression
__.*__
文档ID可能包含空格字符.
Document Ids may contain space characters.
文档ID，集合ID和字段名称的命名约束在此处完整记录:
The naming constraints on document Ids, collection Ids, and field names are fully documented here:
