我想在访问令牌中添加一个自定义属性(expireAt
),以便MongoDB使用该属性来自动删除过期的访问令牌。
使用AccessToken
模型创建访问令牌时添加自定义属性的效果很好:
const ttl = 600;
const expireAt = new Date();
expireAt.setSeconds(expireAt.getSeconds() + ttl);
const token = await AccessToken.create({ ttl, expireAt });
但是,当我想为用户创建访问令牌时,我无法在创建令牌时添加自定义属性exprieAt
,因此我先创建,然后更新它:
const ttl = 600;
const expireAt = new Date();
expireAt.setSeconds(expireAt.getSeconds() + ttl);
// Create the access token for the user
const token = await user.createAccessToken(options);
// Update token to set the custom date and time to expire
token.expireAt = expireAt;
token.save();
// Return the token together with the user data
return Object.assign({}, token.toJSON(), { user });
有没有一种方法可以为具有自定义属性的用户创建令牌(使用实例方法或模型方法就可以),而无需执行两个步骤-创建和更新?
答案 0 :(得分:0)
因此,看来AccessToken
模型通过userId
属性(参考:https://github.com/strongloop/loopback/blob/master/common/models/access-token.json#L27)与用户建立了联系。
{
"name": "AccessToken",
"properties": {
"id": {
"type": "string",
"id": true
},
"ttl": {
"type": "number",
"ttl": true,
"default": 1209600,
"description": "time to live in seconds (2 weeks by default)"
},
"scopes": {
"type": ["string"],
"description": "Array of scopes granted to this access token."
},
"created": {
"type": "Date",
"defaultFn": "now"
}
},
"relations": {
"user": {
"type": "belongsTo",
"model": "User",
"foreignKey": "userId"
}
},
"acls": [
{
"principalType": "ROLE",
"principalId": "$everyone",
"permission": "DENY"
}
]
}
要将令牌链接到用户,我们只需要传递值userId
:
AccessToken.create({ ttl, expireAt, userId });
