> 如果 api 地址中有变量,比如 `/api/mock2/sample/${id}`amis 就不会自动加上分页参数,需要自己加上,改成 `/api/mock2/sample/${id}?page=${page}&perPage=${perPage}`
## 分页参数
默认的分页参数是 `page``perPage`page 代表页数比如第一页perPage 代表每页显示几行。
如果要其它格式,比如转成 `limit``offset`,可以使用公式来转换,比如
`/api/mock2/sample?limit=${perPage}&offset=${(page - 1) * perPage}`
## 功能
既然这个渲染器叫增删改查,那接下来分开介绍这几个功能吧。

## GraphQL
1.7.0 及之前的版本需要通过配置 `data` 里的 `query``variables` 字段可以实现 GraphQL 查询
```schema: scope="body"
{
"type": "form",
"api": {
"method": "post",
"url": "/api/mock2/form/saveForm",
"data": {
"query": "mutation AddUser($name: String!, $email: String!) { \
insert_user(object: { title: $title, email: $email }) { \
title \
email \
} \
}",
"variables": {
"name": "${name}",
"email": "${email}"
}
}
},
"body": [
{
"type": "input-text",
"name": "name",
"label": "姓名:"
},
{
"name": "email",
"type": "input-email",
"label": "邮箱:"
}
]
}
```
1.8.0 及以上版本简化了 GraphQL 的支持,增加了 `graphql` 属性,如果配置了就会自动并自动将 data 当成 `variables`,上面的例子可以简化为下面的写法,除了简化之外还方便了可视化编辑器编辑
```schema: scope="body"
{
"type": "form",
"api": {
"method": "post",
"url": "/api/mock2/form/saveForm",
"graphql": "mutation AddUser($name: String!, $email: String!) { \
insert_user(object: { name: $name, email: $email }) { \
name \
email \
} \
}"
},
"body": [
{
"type": "input-text",
"name": "name",
"label": "姓名:"
},
{
"name": "email",
"type": "input-email",
"label": "邮箱:"
}
]
}
```
如果设置了 `data` 会被当成 `variables`,比如在 CRUD 里设置分页参数,比如下面的例子
```json
{
"type": "crud",
"api": {
"url": "/api/mock2/sample",
"method": "post",
"graphql": "{ pages(page: $page, perPage: $perPage) { id, engine } }",
"data": {
"page": "${page}",
"perPage": "${perPage}"
}
},
"columns": [
{
"name": "id",
"label": "ID"
},
{
"name": "engine",
"label": "Rendering engine"
}
]
}
```
