### 远程拉取字典
|
||||
|
||||
> since 1.1.6
|
||||
|
||||
通过配置 `source` 接口来实现，接口返回字典对象即可，数据格式参考 map 配置。
|
||||
|
||||
```schema: scope="body"
|
||||
{
|
||||
"type": "form",
|
||||
"data": {
|
||||
"type": "2"
|
||||
},
|
||||
"controls": [
|
||||
{
|
||||
"type": "mapping",
|
||||
"name": "type",
|
||||
"label": "映射",
|
||||
"source": "https://3xsw4ap8wah59.cfc-execute.bj.baidubce.com/api/amis-mock/mapping"
|
||||
}
|
||||
]
|
||||
}
|
||||
```
|
||||
|
||||
> 默认 source 是有 30s 缓存的，通常字典数据不长变更。如果想修改，请参考 [API](../../../docs/types/api) 文档配置缓存。
|
||||
|
||||
### 关联上下文变量
|
||||
|
||||
> since 1.1.6
|
||||
|
||||
同样通过配置 `source` 来实现，只是格式是取变量。
|
||||
|
||||
```schema: scope="body"
|
||||
{
|
||||
"type": "form",
|
||||
"initApi": {
|
||||
"url": "https://3xsw4ap8wah59.cfc-execute.bj.baidubce.com/api/amis-mock/mapping",
|
||||
"method": "get",
|
||||
"responseData": {
|
||||
"zidian": "$$$$",
|
||||
"type": "2"
|
||||
}
|
||||
},
|
||||
"controls": [
|
||||
{
|
||||
"type": "mapping",
|
||||
"name": "type",
|
||||
"label": "映射",
|
||||
"source": "$${zidian}"
|
||||
}
|
||||
]
|
||||
}
|
||||
```
|
||||
|
||||
