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_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

@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

 @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)
