我需要删除request.auth.phone_number返回的字符串处的加号信号。为此,我尝试使用替换功能,但是收到以下错误:“找不到功能错误:名称:[replace]。”;
match /test/{id} {
allow read, update, delete, create: if request.auth != null && (resource.data.items[request.auth.token.phone_number.replace('+', '')] == true || resource == null);
}
当我在实时数据库上运行时,这很好。例如:
"tests": {
"$uid": {
".write": "auth.uid.replace('+', '') === '5521999991234'"
}
}
在Cloud Firestore数据库中,有没有办法使用字符串函数,例如“ contains(),replace(),toLowerCase()”等?
谢谢

Firestore安全规则使用的语言与实时数据库完全不同。
您可以在API documentation中看到字符串对象上所有可用方法的列表。您要求做的唯一实际可用的是lower和matches。

您可以编写这样的函数:
function replace(string, replace, by) {
return string.split(replace).join(by)
}
并使用它。.
replace('+3312312345', '+', '')
在您的示例中:
match /test/{id} {
allow read, write: if request.auth != null &&
(resource.data.items[replace(request.auth.token.phone_number, '+', '')]
== true || resource == null);
}
// below your rules
function replace(string, replace, by) {
return string.split(replace).join(by)
}

更新:几个月前添加了.flowconfig
方法。您现在可以做类似的事情
