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)

参数说明

tableName 和 tableID 二选一，不能同时存在

参数类型必填说明
tableIDNumber是数据表的 ID
tableNameString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
recordIDString是记录 ID

示例

请求示例

  1. let tableName = 'product'
  2. let recordID = '59897882ff650c0477f00485'
  4. let Product = new wx.BaaS.TableObject(tableName)
  6. Product.get(recordID).then(res => {
  7.   // success
  8. }, err => {
  9.   // err
  10. })
  1. let tableName = 'product'
  2. let recordID = '59897882ff650c0477f00485'
  4. let Product = new qq.BaaS.TableObject(tableName)
  6. Product.get(recordID).then(res => {
  7.   // success
  8. }, err => {
  9.   // err
  10. })
  1. let tableName = 'product'
  2. let recordID = '59897882ff650c0477f00485'

返回示例

res 结构如下:

  1. {
  2.   "statusCode": 200,
  3.   "data": {
  4.     "_id": "59a3c2b5afb7766a5ec6e84e",
  5.     "amount": 0,
  6.     "created_at": 1503904437,
  7.     "created_by": 36395395,
  8.     "desc": ["good"],
  9.     "id": "59a3c2b5afb7766a5ec6e84e",
  10.     "name": "apple",
  11.     "price": 1.0,
  12.     "read_perm": ["user:*"],
  13.     "updated_at": 1503904437,
  14.     "write_perm": ["user:*"]
  15.   }
  16. }

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
