## 开发准备

上一节我们实现了回收金提现的功能，并且成功展示了当前账户的支出列表，但是我们的提现相关的记录并没有很好的给用户做出展示，用户只知道当前账户提现扣款，并不知道回收金的去向，这一节我们就要实现回收金记录的查询添加、查询、展示

## 功能分析

要实现这些功能我们需要新建一张表，根据当前用户绑定的信息去填充对应的信息，把提现的银行卡，提现状态，提现时间，提现金额都先添加到表里，在用户进入提现记录页面之后，通过userid去查询当前用户的记录然后在列表里进行展示

## 代码实现

首先我们创建对应的提现记录表

```css

{

"objectTypeName": "withdrawal_record",

"fields": [

{"fieldName": "id", "fieldType": "Integer", "notNull": true, "belongPrimaryKey": true},

{"fieldName": "user_id", "fieldType": "Integer", "notNull": true, "defaultValue": 0},

{"fieldName": "bank_name", "fieldType": "String"},

{"fieldName": "bank_num", "fieldType": "String"},

{"fieldName": "creat_time", "fieldType": "String"},

{"fieldName": "type_str", "fieldType": "String"},

{"fieldName": "money", "fieldType": "Double"}

],

"indexes": [

{"indexName": "field1Index", "indexList": [{"fieldName":"id","sortType":"ASC"}]}

],

"permissions": [

{"role": "World", "rights": ["Read", "Upsert", "Delete"]},

{"role": "Authenticated", "rights": ["Read", "Upsert", "Delete"]},

{"role": "Creator", "rights": ["Read", "Upsert", "Delete"]},

{"role": "Administrator", "rights": ["Read", "Upsert", "Delete"]}

]

}

```

我们生成对应的实体和db类之后，在提现成功的提交记录里，把我们表需要的信息添加进去

```css

let record=new withdrawal_record()

record.id=Math.floor(Math.random() * 1000000)

record.user_id=this.user!.user_id

record.bank_name=this.bankList[0].bank_name

record.bank_num=this.bankList[0].bank_card

record.creat_time=this.year+"-"+this.month+"-"+this.day+" "+this.time

record.type_str='0'

record.money=this.moneyNum

let status = await databaseZone.upsert(record);

```

添加完成之后我们新建一个提现记录展示页面

```css

@Entry

@Component

struct WithdrawalRecordPage {

@State user: User|null=null

build() {

Column() {

CommonTopBar({ title: "提现记录", alpha: 0, titleAlignment: TextAlign.Center ,backButton:true})

}

.backgroundColor("#F1F3F5")

.height('100%')

.width('100%')

}

}

```

首先进行数据的查询

```css

@State user: User|null=null

@State withdrawalRecordList:WithdrawalRecord[]=[]

async aboutToAppear(): Promise<void> {

const value = await StorageUtils.getAll('user');

if (value != "") {

this.user = JSON.parse(value)

}

let databaseZone = cloudDatabase.zone('default');

let condition = new cloudDatabase.DatabaseQuery(withdrawal_record);

condition.equalTo("user_id", this.user?.user_id)

let listData = await databaseZone.query(condition);

let json = JSON.stringify(listData)

let data: WithdrawalRecord[] = JSON.parse(json)

if (data.length>0) {

this.withdrawalRecordList=data

}

}

```

然后把我们查询到的数据展示到列表组件中

```css

List({space:10}){

ForEach(this.withdrawalRecordList,(item:WithdrawalRecord,index:number)=>{

ListItem(){

Column({space:10}){

Row(){

Text(item.type_str=='0'?"提现成功":"提现中")

.fontColor(item.type_str=='0'?Color.Green:Color.Black)

.fontSize(16)

.fontWeight(FontWeight.Bold)

Text("¥"+item.money+"")

.fontSize(16)

.fontWeight(FontWeight.Bold)

.fontColor(Color.Black)

}

.width('100%')

.justifyContent(FlexAlign.SpaceBetween)

Row(){

Text(item.bank_name+" ("+item.bank_num+")")

.fontColor(Color.Black)

.fontSize(14)

.fontWeight(FontWeight.Bold)

Text(item.creat_time+"")

.fontSize(14)

.fontWeight(FontWeight.Bold)

.fontColor(Color.Grey)

}

.width('100%')

.justifyContent(FlexAlign.SpaceBetween)

}

.padding(10)

.width('100%')

.borderRadius(10)

.backgroundColor(Color.White)

}

})

}

.padding(10)

```
