上一篇文章中我们实现了项目端云一体化首页部分模块动态配置，实现了对模块模块的后端控制显示和隐藏，这能让我们的app更加的灵活，也能应对更多的情况。现在我们来对配置模块进行完善，除了已有的模块以外，我们还有一些banner ，活动入口等模块，这些模块的数据并不多，所以我们也归纳到配置中去实现。并且我们在配置表中添加了一些不同的id，我们只需要根据相对应的id 去查询对应的表就可以了
**代码实现**
实现横幅海报，商品活动入口
创建海报横幅表
{
"objectTypeName": "home_poster",
"fields": [
{"fieldName": "id", "fieldType": "Integer", "notNull": true, "belongPrimaryKey": true},
{"fieldName": "poster_id", "fieldType": "Integer", "notNull": true, "defaultValue": 0},
{"fieldName": "url", "fieldType": "String"},
{"fieldName": "router", "fieldType": "String"}
],
"indexes": [
{"indexName": "posterIdIndex", "indexList": [{"fieldName":"poster_id","sortType":"ASC"}]}
],
"permissions": [
{"role": "World", "rights": ["Read"]},
{"role": "Authenticated", "rights": ["Read", "Upsert"]},
{"role": "Creator", "rights": ["Read", "Upsert", "Delete"]},
{"role": "Administrator", "rights": ["Read", "Upsert", "Delete"]}
]
}
创建商品活动入口表
{
"objectTypeName": "home_good_center",
"fields": [
{"fieldName": "id", "fieldType": "Integer", "notNull": true, "belongPrimaryKey": true},
{"fieldName": "good_left_id", "fieldType": "Integer", "notNull": true, "defaultValue": 0},
{"fieldName": "title", "fieldType": "String"},
{"fieldName": "url", "fieldType": "String"}
],
"indexes": [
{"indexName": "goodLeftIdIndex", "indexList": [{"fieldName":"good_left_id","sortType":"ASC"}]}
],
"permissions": [
{"role": "World", "rights": ["Read"]},
{"role": "Authenticated", "rights": ["Read", "Upsert"]},
{"role": "Creator", "rights": ["Read", "Upsert", "Delete"]},
{"role": "Administrator", "rights": ["Read", "Upsert", "Delete"]}
]
}
分别填充数据
海报
{
"cloudDBZoneName": "default",
"objectTypeName": "home_poster",
"objects": [
{
"id": 10,
"poster_id": 1,
"url": "在线图片链接",
"router": "string1"
}
]
}
商品活动入口
{
"cloudDBZoneName": "default",
"objectTypeName": "home_good_center",
"objects": [
{
"id": 10,
"good_left_id": 1,
"title": "生鲜严选",
"url": "在线图片链接"
},
{
"id": 20,
"good_left_id": 1,
"title": "西购新品",
"url": "在线图片链接"
},
{
"id": 30,
"good_left_id": 1,
"title": "今日推荐",
"url": "在线图片链接"
}
]
}
都填充完成后，我们把数据提交到云端，然后进行配置类的同步
接下来我们进行数据查询，因为我们在配置表中添加了id ，所以我们要查询出对应id的活动入口。
@State homeActivity:HomeActivitySetting[]=[]//首页活动配置
@State homeGoodCenter:HomeGoodCenter[]=[]//商品活动入口
let listData3 = await databaseZone.query(condition3);
let json3 = JSON.stringify(listData3)
let data3:HomeActivitySetting[]= JSON.parse(json3)
this.homeActivity=data3
hilog.error(0x0000, 'testTag', `Failed to query data, code: ${this.homeActivity}`);
let list5 = await databaseZone.query(home_good);
home_good.equalTo("good_left_id",data3[0].good_left_id);
let json5 = JSON.stringify(list5)
let data5:HomeGoodCenter[]= JSON.parse(json5)
this.homeGoodCenter=data5
hilog.error(0x0000, 'testTag', `Failed to query data, code: ${this.homeGoodCenter}`);
然后我们修改一下商品活动入口的内容
import { HomeGoodCenter } from "../entity/HomeGoodCenter"
@Component
@Preview
export struct SpecialColumn {
@Link goodInfo: HomeGoodCenter[]
build() {
Column(){
List({space:10}){
ForEach(this.goodInfo,(data:HomeGoodCenter)=>{
ListItem(){
Column(){
Text(data.title)
.fontSize(16)
.fontWeight(FontWeight.Bold)
.fontColor(Color.Black)
Blank()
Image(data.url)
.width('28%')
.height(90)
.margin({ bottom: 8 })
.objectFit(ImageFit.Cover)
}
.borderRadius(5)
.backgroundColor("#ffeedeb8")
.padding(5)
}
})
}
.listDirection(Axis.Horizontal)
}
.margin({top:10})
}
}
在首页进行调用
SpecialColumn({goodInfo:this.homeGoodCenter})
到这里我们就实现了活动配置相关的内容
