Harmony应用开发-用户头像认证实现

说明
本模块首批接口从API version 6开始支持。后续版本的新增接口，采用上角标单独标记接口的起始版本。

一.创建项目
二.示例代码
index.hml

<div class="container">
    <div class="img">
        <text>获取头像</text>
    </div>
    <text class="title">
        <span>是否进行用户认证</span>
    </text>
    <div class="btn">
        <button value="取消认证" onclick="cancelAuth"></button>
        <button value="确定认证" onclick="startAuth"></button>
    </div>
</div>

index.css

.container {
    display: flex;
    flex-direction: column;
    justify-content: center;
    align-items: center;
    width: 100%;
    height: 400px;
}
.img{
    flex-direction: column;
    justify-content: center;
    align-items: center;
    width: 150px;
    height: 150px;
    border: 1px solid #ccc;
    border-radius: 75px;
    margin-bottom: 10px;
}
.title {
    font-size: 30px;
    text-align: center;
}
.btn{
    width: 100%;
    height: 80px;
    flex-direction: row;
    align-items: center;
    justify-content: space-around;
}
.btn button{
    width: 90px;
    height: 30px;
}

index.js

import prompt from '@system.prompt';
import userIAM_userAuth from '@ohos.userIAM.userAuth';

export default {
    startAuth() {
        console.info("开始认证");
        let tipCallback = (tip)=>{
            console.info("receive tip: errorCode(" + tip.errorCode + ") code(" + tip.tipCode + ") event(" +
            tip.tipEvent + ") info(" + tip.tipInfo + ")");
            // 此处添加提示信息显示逻辑
        };
        let auth = userIAM_userAuth.getAuthenticator();
        auth.on("tip", tipCallback);
        auth.execute("FACE_ONLY", "S2").then((code)=>{
            auth.off("tip", tipCallback);
            console.info("auth success");
            // 此处添加认证成功逻辑
        }).catch((code)=>{
            auth.off("tip", tipCallback);
            console.error("auth fail, code = " + code);
            // 此处添加认证失败逻辑
        });
        prompt.showToast({message:"认证成功"})

    },

    checkAuthSupport() {
        console.info("start check auth support");
        let auth = userIAM_userAuth.getAuthenticator();
        let checkCode = auth.checkAvailability("FACE_ONLY", "S2");
        if (checkCode == userIAM_userAuth.CheckAvailabilityResult.SUPPORTED) {
            console.info("check auth support success");
            // 此处添加支持指定类型认证的逻辑
        } else {
            console.error("check auth support fail, code = " + checkCode);
            // 此处添加不支持指定类型认证的逻辑
        }
    },

    cancelAuth() {
        console.info("取消");
        let auth = userIAM_userAuth.getAuthenticator();
        let cancelCode = auth.cancel();
        if (cancelCode == userIAM_userAuth.Result.SUCCESS) {
            console.info("cancel auth success");
        } else {
            console.error("cancel auth fail");
        }
    }
}
