我对此Cloud Firestore安全规则有疑问:
service cloud.firestore {
match /databases/{database}/documents {
match /stages/{stageId} {
match /collections/{collectionId} {
match /pois/{poiId} {
allow read;
allow write: if request.auth != null ||
request.method == "update" &&
request.resource.data.keys() == ["pm"];
}
}
}
}
}
在代码中,我尝试使用值字典将现有文档的字段pm
更新为未经身份验证的用户。 Firestore日志显示此请求:

此请求因“缺少权限或权限不足”而失败。
当我使用此模拟数据模拟从update
到stages/dev/collections/ETzbIXBn0Z5FOsCHtHlv/pois/zJELKLTWupuMkYQNb9gl
时
{"__name__":"/databases/(default)/documents/stages/dev/collections/ETzbIXBn0Z5FOsCHtHlv/pois/zJELKLTWupuMkYQNb9gl","data":{"pm":{"adminArea":"Germany","testArea":"Munich"}}}
模拟器允许更新。
在我的代码(Swift项目/ iOS)中,我在现有文档参考上使用updateData
方法。
作为参数,我传递了这个数组:
["pm": ["adminArea": "Faro", "name": "Rua Primeiro de Dezembro", "postalCode": "8200-142", "locality": "Albufeira", "subLocality": "Albufeira", "isoCountryCode": "PT", "timezone": "Europe/Lisbon", "thoroughfare": "Rua Primeiro de Dezembro", "country": "Portugal"]]
知道我在做什么错吗?谢谢!
答案 0 :(得分:2)
事实证明
request.resource.data.keys() == ["pm"];
在部署时没有按预期方式工作(即使它在模拟器中也是如此)。
用
替换request.writeFields.size() == 1 && "pm" in request.writeFields;
是我的把戏。
模拟规则是迈向实用产品的重要一步(Hello Google:调试规则???),但前提是它们在模拟器中的作用与在实时部署中的作用相同...
答案 1 :(得分:0)
您可以重写此
request.resource.data.keys() == ["pm"];
使用
request.writeFields == ["pm"];
