3.1 主动通知接口
### 1、通知地址
当有新数据或订单状态变化时，会发送 (POST)请求到合作用户平台请求处理
合作用户在镖局物流平台填写通知地址 例如：
```
https://www.myapp.com/receive
```
### 2、镖局物流通知参数
- 通知内容（Json 格式 BASE64 加密）
- base64_encode(json_encode(xxx))
- 字段
| 字段名称 | 字段类型 | 默认值 | 必填 | 备注 |
| ------ | --------| ----- | ----| -----|
| notify | string | | true |通知类型，可选参数如下<br>[orderChange]<br> orderChange 订单更新触发通知，<br>当有待处理订单提交到镖局物流平时，触发此通知。<br>通知时返回以下参数orderInfo,为镖局物流订单号集合 |
| timestamp | int | | true |当前 Unix 时间戳,10 位整型数字 |
| sign | string | | true |通知密钥|
### 3、notify 通知内容示例：
```json
{
"notify":"orderChange", "orderInfo":{
"codes":[
"内部订单号",
"内部订单号",
...
"内部订单号"
],
"count":"返回单号数"
}
}
```
- sign 通知密钥
sign = md5(notify=通知内容×tamp=当前Unix 时间戳 apiKey)
### 4、实例
timestamp = "1433139940"
apiKey = "6168f305888c3d795e67c6de17bf8a21" //在镖局物流的 apiKey
***注：base64 结果中会出现加号（+）情况。经过网络请求后，导致加号（+）被转为空格，如果验证密钥， 传入的 base64 结果中出现空格，请转回加号***
