ohpm install @youzanyun/app_web
在加载有赞页面之前对SDK进行初始化，比如：在EntryAbility的onCreate方法中，示例如下:
export default class EntryAbility extends UIAbility {
onCreate(want: Want, launchParam: AbilityConstant.LaunchParam): void {
YouzanSDK.init(this.context, new InitConfig(
false,
"申请的clientid",
"申请的clientKey",
{
support: true
},
{
supportLoading: true,
supportLongPress: true
}))
}
}需要传入一个UIAbilityContext和InitConfig实例，InitConfig实例可以配置clientId、clientKey等等，具体参数说明如下：
debug：是否开启debug模式clientId：您申请的clientIdclientKey：您申请的clientKeylogConfig：日志相关的配置，可以配置support参数，确定是否开启日志打印webConfig：web相关的配置，可以配置supportLongPress参数，确定是否支持长按保存图片
web组件主要依赖三个参数：
url：需要加载的web地址delegate：继承于YzWebEventClient的实例，YzWeb基于系统Web组件，系统Web组件所有的事件通过delegate分发出来，供业务方使用controller：继承于YzWebviewController的实例，YzWebviewController继承于系统的WebviewController，封装了涉及有赞的跳转、js bridge注册、url返回等方法
自定义WebviewController，需继承YzWebviewController，YzWebviewController是继承了鸿蒙 webview.WebviewController，封装了涉及有赞的跳转、js bridge注册、url返回等方法
通过registerJSSubscriber方法订阅有赞的JS事件，具体事件Key对应事件说明如下：
| 事件Key | 说明 |
|---|---|
| KEY_AUTHENTICATION | 获取用户信息 |
| KEY_PAGE_READY | Web页面已准备好，分享接口可用 |
| KEY_SHARE | 分享事件 |
| KEY_FILE_CHOOSER | 文件选择事件 |
| KEY_CUSTOM_ACTION | 通用自定义事件 |
| KEY_ADD_TO_CART | 用户添加商品到购物车 |
| KEY_BUY_NOW | 商品详情页点击“立即购买” |
| KEY_ADD_UP | 购物车页面点击“结算”时回调 |
| KEY_PAYMENT_FINISHED | 支付完成回到结果页，结果页收到支付成功回调 |
| KEY_CHECK_AUTH_MOBILE | 登陆完成后的回调 |
| KEY_AUTHORIZATION_SUCCESS | 一键登录成功回调 |
| KEY_AUTHORIZATION_ERROR | 一键登录失败回调 |
| KEY_INVOKE_DISAGREE_PROTOCOL | 不同意协议并退出 |
| KEY_INVOKE_GO_CASHIER | 拉起三方收银台 |
| KEY_INVOKE_CANCEL_ACCOUNT_SUCCESS | 账号注销成功回调 |
| KEY_INVOKE_CANCEL_ACCOUNT_FAIL | 账号注销失败回调 |
| KEY_INVOKE_CHANGE_PULL_REFRESH | 当前页面下拉刷新功能开关 |
根据业务方具体需求，按需订阅，示例如下:
import { JsSubscribeKey } from '@youzanyun/app_web/src/main/ets/model/constant/JsDefine';
import { YzWebviewController } from '@youzanyun/app_web/src/main/ets/components/YzWebviewController';
import { UserInfoReqBO } from '@youzanyun/app_web/src/main/ets/model/req/request';
import { YouzanSDK } from '@youzanyun/app_web';
export class MyWebviewController extends YzWebviewController {
private doJsEvent(key: string, params: string) {
switch (key) {
case JsSubscribeKey.KEY_AUTHENTICATION: { // 用户登录
YouzanSDK.queryUserInfo(new UserInfoReqBO(
"31467761", // 有赞openId 必传 开发者自身系统的用户ID，是三方App帐号在有赞的唯一标示符，如更换将导致原用户数据丢失
"https://cdn.daddylab.com/Upload/android/20210113/021119/au9j4d6aed5xfweg.jpeg?w=1080&h=1080", // 头像信息
"一百亿养乐多", // 非必传，用户头像，建议传入https的url
"0", // 非必传，性别 0（保密）1（男）2（女）
"" // 非必传，用户额外参数
))
.then((data) => {
setTimeout(() => {
this.refresh()
}, 500)
promptAction.showToast({ message: "请求成功" })
})
.catch(() => {
promptAction.showToast({ message: "请求失败" })
})
break
}
default: {
break
}
}
}
//------------------- YZJs subscribe
registerYZJSSubscribers() {
const eventKeys = [
JsSubscribeKey.KEY_AUTHENTICATION,
JsSubscribeKey.KEY_PAGE_READY,
JsSubscribeKey.KEY_SHARE,
JsSubscribeKey.KEY_FILE_CHOOSER,
JsSubscribeKey.KEY_CUSTOM_ACTION,
JsSubscribeKey.KEY_ADD_TO_CART,
JsSubscribeKey.KEY_BUY_NOW,
JsSubscribeKey.KEY_WX_PAY,
JsSubscribeKey.KEY_ADD_UP,
JsSubscribeKey.KEY_PAYMENT_FINISHED,
JsSubscribeKey.KEY_CHECK_AUTH_MOBILE,
JsSubscribeKey.KEY_AUTHORIZATION_SUCCESS,
JsSubscribeKey.KEY_AUTHORIZATION_ERROR,
JsSubscribeKey.KEY_INVOKE_DISAGREE_PROTOCOL,
JsSubscribeKey.KEY_INVOKE_GO_CASHIER,
JsSubscribeKey.KEY_INVOKE_CANCEL_ACCOUNT_SUCCESS,
JsSubscribeKey.KEY_INVOKE_CANCEL_ACCOUNT_FAIL,
JsSubscribeKey.KEY_INVOKE_CHANGE_PULL_REFRESH,
]
eventKeys.forEach((item) => {
this.registerJSSubscriber({
"key": item,
"onCall": (key: string, params: string) => {
this.doJsEvent(key, params)
}
})
})
}
}自定义WebEventClient，需继承于YzWebEventClient。因为鸿蒙组件不支持继承，Web组件的事件通过WebEventClient分发到业务层，WebEventClient中的事件基本都是透传Web组件原生的事件，具体事件可以参考Web组件的事件。
