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

{"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

 let record=new withdrawal_record()record.id=Math.floor(Math.random() * 1000000)record.user_id=this.user!.user_idrecord.bank_name=this.bankList[0].bank_namerecord.bank_num=this.bankList[0].bank_cardrecord.creat_time=this.year+"-"+this.month+"-"+this.day+" "+this.timerecord.type_str='0'record.money=this.moneyNumlet 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

@Entry
@Component
struct WithdrawalRecordPage {@State user: User|null=nullbuild() {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

 @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

 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)

现在让我们运行代码查看效果
