拉起金融类应用（startAbilityByType）

本章节介绍如何拉起金融类应用扩展面板。

金融类应用扩展面板参数说明

startAbilityByType接口中type字段为finance，对应的wantParam参数：

参数名	类型	必填	说明
sceneType	number	否	意图场景，表明本次请求对应的操作意图。1：转账汇款 2：信用卡还款。默认为1
bankCardNo	string	否	银行卡卡号

拉起方开发步骤

导入相关模块。 ts import { common } from '@kit.AbilityKit';

构造接口参数并调用startAbilityByType接口。

@Entry
@Component
struct Index {
    @State hideAbility: string = 'hideAbility'


    build() {
        Row() {
            Column() {
                Text(this.hideAbility)
                    .fontSize(30)
                    .fontWeight(FontWeight.Bold)
                    .onClick(() => {
                        let context = this.getUIContext().getHostContext() as common.UIAbilityContext;
                        let wantParam: Record<string, Object> = {
                            'sceneType': 1,
                            "bankCardNo": '123456789'
                        };
                        let abilityStartCallback: common.AbilityStartCallback = {
                            onError: (code: number, name: string, message: string) => {
                                console.log(`onError code ${code} name: ${name} message: ${message}`);
                            },
                            onResult: (result) => {
                                console.log(`onResult result: ${JSON.stringify(result)}`);
                            }
                        }


                        context.startAbilityByType("finance", wantParam, abilityStartCallback,
                            (err) => {
                                if (err) {
                                    console.error(`startAbilityByType fail, err: ${JSON.stringify(err)}`);
                                } else {
                                    console.log(`success`);
                                }
                            });
                    });
            }
            .width('100%')
        }
        .height('100%')
    }
}

目标方开发步骤

在module.json5中配置uris，步骤如下：

设置linkFeature属性以声明当前应用支持的特性功能，从而系统可以从设备已安装应用中找到当前支持该特性的应用，取值范围如下：

|取值 |含义 | |————–|—————————-| |Transfer |声明应用支持转账汇款功能 | |CreditCardRepayment |声明应用支持信用卡还款功能 | 2. 设置scheme、host、port、path/pathStartWith属性，与Want中URI相匹配，以便区分不同功能。

{
  "abilities": [
      {
      "skills": [
          {
          "uris": [
              {
              "scheme": "finance", // 这里仅示意，应用需确保这里声明的uri能被外部正常拉起
              "host": "transfer",
              "path": "",
              "linkFeature": "Transfer" // 声明应用支持转账汇款功能
              },
              {
              "scheme": "finance", // 这里仅示意，应用需确保这里声明的uri能被外部正常拉起
              "host": "credit_card_repayment",
              "path": "",
              "linkFeature": "CreditCardRepayment" // 声明应用支持信用卡还款功能
              }
          ]
          }
      ]
      }
  ]
}

解析面板传过来的参数并做对应处理。
```
UIAbility.onCreate(want: Want, launchParam: AbilityConstant.LaunchParam): void
```
在参数want.uri中会携带目标方配置的linkFeature对应的uri;

在参数want.parameters中会携带Caller方传入的参数，如下表所示：

|参数名 |类型 |必填|说明| |——————–|————————————————————|——–|——–| |bankCardNo|string|否|银行卡卡号|

应用可根据[linkFeature](https://www.seaxiang.com/blog/e919364aa72c48bc866e9b51356847bb)中定义的特性功能，比如转账汇款和信用卡还款，结合接收到的uri开发不同的样式页面。
