我用findAll查询了分类的数据
const list = await model.findAll()
打印list如下：
[
Category {
dataValues: {
id: 1,
name: 'js',
parentId: null,
createdAt: '2020-03-15 12:35:49',
updatedAt: '2020-03-15 12:35:49',
deletedAt: null,
children: [Array]
},
_previousDataValues: {
id: 1,
name: 'js',
parentId: null,
createdAt: '2020-03-15 12:35:49',
updatedAt: '2020-03-15 12:35:49',
deletedAt: null,
children: [Array]
},
_changed: {},
_modelOptions: {
timestamps: true,
validate: {},
freezeTableName: false,
underscored: false,
paranoid: true,
rejectOnEmpty: false,
whereCollection: [Object],
schema: null,
schemaDelimiter: '',
defaultScope: {},
scopes: {},
indexes: [],
name: [Object],
omitNull: false,
sequelize: [Sequelize],
hooks: {}
},
_options: {
isNewRecord: false,
_schema: null,
_schemaDelimiter: '',
include: [Array],
includeNames: [Array],
includeMap: [Object],
includeValidated: true,
attributes: [Array],
raw: true
},
isNewRecord: false,
children: [ [Category] ]
},
Category {
dataValues: {
id: 3,
name: 'css',
parentId: null,
createdAt: '2020-06-12 01:00:39',
updatedAt: '2020-06-12 01:00:39',
deletedAt: null,
children: []
},
_previousDataValues: {
id: 3,
name: 'css',
parentId: null,
createdAt: '2020-06-12 01:00:39',
updatedAt: '2020-06-12 01:00:39',
deletedAt: null,
children: []
},
_changed: {},
_modelOptions: {
timestamps: true,
validate: {},
freezeTableName: false,
underscored: false,
paranoid: true,
rejectOnEmpty: false,
whereCollection: [Object],
schema: null,
schemaDelimiter: '',
defaultScope: {},
scopes: {},
indexes: [],
name: [Object],
omitNull: false,
sequelize: [Sequelize],
hooks: {}
},
_options: {
isNewRecord: false,
_schema: null,
_schemaDelimiter: '',
include: [Array],
includeNames: [Array],
includeMap: [Object],
includeValidated: true,
attributes: [Array],
raw: true
},
isNewRecord: false,
children: []
}
]
然后我把list给ctx.body返回
ctx.body = list
打印的response中，list是正确的json，而不是上面的对象，json如下：
[
{
"id":?1,
"name":?"js",
"parentId":?null,
"createdAt":?"2020-03-15 12:35:49",
"updatedAt":?"2020-03-15 12:35:49",
"deletedAt":?null,
"children":?[
{
"id":?2,
"name":?"ts",
"parentId":?1,
"createdAt":?"2020-06-12 01:00:29",
"updatedAt":?"2020-06-12 01:00:29",
"deletedAt":?null,
"children":?[],
"articles":?[]
}
]
},
{
"id":?3,
"name":?"css",
"parentId":?null,
"createdAt":?"2020-06-12 01:00:39",
"updatedAt":?"2020-06-12 01:00:39",
"deletedAt":?null,
"children":?[]
}
]
为什么会不一样呢？还是sequelize对这个封装对象做了什么处理？
