隐私弹窗：

1. 启用隐私相关功能在manifest.json文件中配置 __usePrivacyCheck__: true：

"mp-weixin" : {
        "__usePrivacyCheck__" : true,
    },

2. 创建组件：

<template>
	<view>
		<!-- 隐私政策弹窗 -->
		<uni-popup ref="popup">
			<view class="popupWrap">
				<view class="popupTxt">
					在您使用【最美万年历】之前，请仔细阅读<text class="blueColor"
						@click="handleOpenPrivacyContract">{{privacyContractName}}</text>。如您同意{{privacyContractName}},请点击“同意”开始使用【最美万年历】。
				</view>
				<view class="popupBot">
					<button id="disagree-btn" type="default" @click="handleDisagree">拒绝</button>
					<button id="agree-btn" type="primary" open-type="agreePrivacyAuthorization"
						@agreeprivacyauthorization="handleAgreePrivacyAuthorization">同意</button>
				</view>
			</view>
		</uni-popup>
	</view>
</template>

<script>
	export default {
		name: "privacyPopup",
		data() {
			return {
				privacyContractName: "" //协议名称
			};
		},
		mounted() {
			wx.getPrivacySetting({
				success: res => {
					console.log("是否需要授权：", res, res.needAuthorization, "隐私协议的名称为：", res.privacyContractName)
					if (res.needAuthorization) {
						this.privacyContractName = res.privacyContractName;
						this.$refs.popup.open('center')
					}
				},
				fail: () => {},
				complete: () => {},
			})
		},
		methods: {
			handleDisagree(e) {
				this.$refs.popup.close()
			},
			handleAgreePrivacyAuthorization(res) {
				// 用户同意隐私协议事件回调
				// 用户点击了同意，之后所有已声明过的隐私接口和组件都可以调用了
				this.$refs.popup.close()
                //通知父组件
				this.$emit("agreePrivacy")
				console.log(res, "handleAgreePrivacyAuthorization");
			},
			handleOpenPrivacyContract() {
				// 打开隐私协议页面
				wx.openPrivacyContract({
					success: () => {}, // 打开成功
					fail: () => {}, // 打开失败
					complete: (res) => {
						console.log(res, "openPrivacyContract complete");
					}
				})
			},
		}
	}
</script>

<style lang="scss">
	.popupWrap {
		width: 540rpx;
		box-sizing: border-box;
		padding: 42rpx;
		background: white;
		border-radius: 30rpx;

		.blueColor {
			color: rgba(39, 152, 240, 1);
		}

		.popupTxt {
			line-height: 48rpx;
		}

		.popupBot {
			display: flex;
			justify-content: space-around;
			align-items: center;
			margin-top: 30rpx;
		}
	}
</style>

2. 在需要授权的页面引入改组件

例：

<privacyPopup @agreePrivacy="执行同意协议后的逻辑"></privacyPopup>

PS:

也可使用获取手机号和隐私政策藕合方式 ，这样在用户拒绝隐私协议后 ，再次点击授权手机号 可继续弹出授权弹窗，直至用户同意协议为止

<button id="agree-btn" type="primary" 
open-type="getPhoneNumber|agreePrivacyAuthorization" 
@getphonenumber="handleBindPhone"	
@agreeprivacyauthorization="handleAgreePrivacyAuthorization">同意</button>
