获取单条数据

操作步骤

1.通过 tableName 或 tableID 实例化一个 TableObject 对象，操作该对象即相当于操作对应的数据表，这里推荐用 tableName

let MyTableObject = new wx.BaaS.TableObject(tableName)

let MyTableObject = new qq.BaaS.TableObject(tableName)

let MyTableObject = new BaaS.TableObject(tableName)

let MyTableObject = new my.BaaS.TableObject(tableName)

let MyTableObject = new swan.BaaS.TableObject(tableName)

let MyTableObject = new tt.BaaS.TableObject(tableName)

let MyTableObject = new jd.BaaS.TableObject(tableName)

let MyTableObject = new ks.BaaS.TableObject(tableName)

参数说明

tableName 和 tableID 二选一，不能同时存在

参数 类型 必填 说明
tableID Number 是 数据表的 ID
tableName String 是 数据表名（SDK >= 1.2.0）

2.指定 recordID 执行获取相应数据项操作

MyTableObject.get(recordID)

参数说明

参数 类型 必填 说明
recordID String 是 记录 ID

示例

请求示例

let tableName = 'product'
let recordID = '59897882ff650c0477f00485'

let Product = new wx.BaaS.TableObject(tableName)

Product.get(recordID).then(res => {
  // success
}, err => {
  // err
})
let tableName = 'product'
let recordID = '59897882ff650c0477f00485'

let Product = new qq.BaaS.TableObject(tableName)

Product.get(recordID).then(res => {
  // success
}, err => {
  // err
})
let tableName = 'product'
let recordID = '59897882ff650c0477f00485'

let Product = new BaaS.TableObject(tableName)

Product.get(recordID).then(res => {
  // success
}, err => {
  // err
})
let tableName = 'product'
let recordID = '59897882ff650c0477f00485'

let Product = new my.BaaS.TableObject(tableName)

Product.get(recordID).then(res => {
  // success
}, err => {
  // err
})
let tableName = 'product'
let recordID = '59897882ff650c0477f00485'

let Product = new swan.BaaS.TableObject(tableName)

Product.get(recordID).then(res => {
  // success
}, err => {
  // err
})
let tableName = 'product'
let recordID = '59897882ff650c0477f00485'

let Product = new tt.BaaS.TableObject(tableName)

Product.get(recordID).then(res => {
  // success
}, err => {
  // err
})
let tableName = 'product'
let recordID = '59897882ff650c0477f00485'

let Product = new jd.BaaS.TableObject(tableName)

Product.get(recordID).then(res => {
  // success
}, err => {
  // err
})
let tableName = 'product'
let recordID = '59897882ff650c0477f00485'

let Product = new ks.BaaS.TableObject(tableName)

Product.get(recordID).then(res => {
  // success
}, err => {
  // err
})

返回示例

res 结构如下:

{
  "statusCode": 200,
  "data": {
    "_id": "59a3c2b5afb7766a5ec6e84e",
    "amount": 0,
    "created_at": 1503904437,
    "created_by": 36395395,
    "desc": ["good"],
    "id": "59a3c2b5afb7766a5ec6e84e",
    "name": "apple",
    "price": 1.0,
    "read_perm": ["user:*"],
    "updated_at": 1503904437,
    "write_perm": ["user:*"]
  }
}

err 对象结构请参考错误码和 HError 对象

常见错误：

错误码 err.code 可能的原因
404 数据行不存在
