问题
I'm currently evaluating loopback.io for developing the API portion of a new project, and I'm having problems with setting the correct ACL entries.
What I wish to accomplish is given an auth token, the GET endpoints should only return objects owned by the user. For example, a request to /Shows?access_token=xxxxxx should return only objects owned by the user.
Below is my shows.json file, and my User model is named Podcaster. Any help would be appreciated.
{
"name": "Show",
"base": "PersistedModel",
"idInjection": true,
"options": {
"validateUpsert": true
},
"properties": {
"title": {
"type": "string",
"required": true
},
"description": {
"type": "string"
}
},
"validations": [],
"relations": {
"episodes": {
"type": "hasMany",
"model": "Episode",
"foreignKey": ""
},
"podcaster": {
"type": "belongsTo",
"model": "Podcaster",
"foreignKey": ""
}
},
"acls": [
{
"accessType": "WRITE",
"principalType": "ROLE",
"principalId": "$authenticated",
"permission": "ALLOW",
"property": "create"
},
{
"accessType": "*",
"principalType": "ROLE",
"principalId": "$owner",
"permission": "ALLOW"
},
{
"accessType": "*",
"principalType": "ROLE",
"principalId": "$everyone",
"permission": "DENY"
}
],
"methods": {}
}
回答1:
It's not related to ACL's.
You want to change the business logic of the method. So the best practice is that you create a new method for getting shows owning by current user.
If you want to work your current owner ACl, you need to create a relation between user and show, and set ownerId in the show model.
{
"name": "Show",
"base": "PersistedModel",
"idInjection": true,
"options": {
"validateUpsert": true
},
"properties": {
"title": {
"type": "string",
"required": true
},
"description": {
"type": "string"
},
"description": {
"type": "string"
}
"ownerId": {
"type": "object"
}
},
"validations": [],
"relations": {
"owner": {
"type": "belongsTo",
"model": "user",
"foreignKey": "ownerId"
},
....
