微信小程序-增加隐私协议弹窗

真的加了非常之久，非常简单的一个功能，但是因为之前没弄过，加上系统有点bug,软件也有点抽风......

1. 在微信后台配置-更新用户隐私协议信息
   
2. 增加 "__usePrivacyCheck__" : true, 9月15号之后不加也行，好象今天刚刚好9月15

    "mp-weixin" : {"appid" : "xxxxxxxxxx","__usePrivacyCheck__" : true,"permission": {"scope.userLocation": {"desc": "提供准确的定位服务"}
   },
   "requiredPrivateInfos": ["getLocation"
   ]

   
   
3. 微信开发者工具的基础库切换到>3.0(本地运行和发布时都要改，不改不弹窗)
   
4. 首页增加隐私协议弹窗控件，加在最后一个view的上边

   <!-- #ifdef MP-WEIXIN -->
   <ws-wx-privacy id="privacy-popup"></ws-wx-privacy>
   <!-- #endif -->

   

5. 增加隐私协议组件，增加到components文件夹下
   
   

6. ws-wx-privacy.vue代码：
    

   <template><uni-popup id="privacy" type="center" ref="privacyPopup" :maskClick="false"><view class="ws-privacy-popup" :style="rootStyle"><view class="ws-privacy-popup__header"><!--标题--><view class="ws-picker__title">{{ title }}</view></view><view class="ws-privacy-popup__container"><text>{{ desc }}</text><text class="ws-privacy-popup__container-protocol" :style="protocolStyle"@click="openPrivacyContract">{{ protocol }}</text><text>{{ subDesc }}</text></view><view class="ws-privacy-popup__footer"><button class="is-agree" :style="agreeStyle" id="agree-btn" open-type="agreePrivacyAuthorization"@agreeprivacyauthorization="handleAgree">{{agreeText}}</button><button class="is-disagree" id="disagree-btn" @click="handleDisagree">{{disagreeText}}</button></view></view></uni-popup>
   </template>
   <script>import {getContext,getComponent} from './util'const privacyResolves = new Set() // onNeedPrivacyAuthorization的reslovelet privacyHandler = null// 注册监听if (uni.onNeedPrivacyAuthorization) {console.log('register uni.onNeedPrivacyAuthorization')uni.onNeedPrivacyAuthorization((resolve) => {if (typeof privacyHandler === 'function') {privacyHandler(resolve)}})}export default {name: 'wsWxPrivacy',emits: ['disagree', 'agree'],props: {// 标题title: {type: String,default: '用户隐私保护提示'},// 描述desc: {type: String,default: '感谢您使用本应用，您使用本应用的服务之前请仔细阅读并同意'},// 隐私保护指引名称protocol: {type: String,default: '《用户隐私保护指引》'},// 子描述subDesc: {type: String,default: '。当您点击同意并开始使用产品服务时，即表示你已理解并同意该条款内容，该条款将对您产生法律约束力。如您拒绝，将无法使用相应服务。'},/*** 控制是否可以点击不同意按钮并显示提示。* 如果设置为 true，用户可以点击不同意按钮执行后续逻辑。* 如果设置为 false，点击不同意按钮会显示提示信息，但不会执行后续逻辑。* 默认为 true*/disagreeEnabled: {type: Boolean,default: true, // 默认为可以点击},/*** 配置不同意按钮的提示消息内容。*/disagreePromptText: {type: String,default: '请先仔细阅读并同意隐私协议', // 默认提示消息},// 拒绝按钮文字disagreeText: {type: String,default: '不同意'},// 同意按钮文字agreeText: {type: String,default: '同意并继续'},// 自定义背景颜色bgColor: {type: String,default: ''},// 自定义主题颜色（控制同意按钮和隐私协议名称的颜色）themeColor: {type: String,default: ''}},computed: {rootStyle() {if (this.bgColor) {return `background:${this.bgColor}`} else {return ''}},protocolStyle() {if (this.themeColor) {return `color:${this.themeColor}`} else {return ''}},agreeStyle() {if (this.themeColor) {return `background:${this.themeColor}`} else {return ''}}},created() {privacyHandler = (resolve) => {const context = getContext()const privacyPopup = getComponent(context, '#privacy-popup')if (privacyPopup) {const privacy = getComponent(privacyPopup, '#privacy')if (privacy && privacy.open) {uni.hideLoading()privacy.open()}}privacyResolves.add(resolve)}},methods: {/*** 打开隐私协议*/openPrivacyContract() {wx.openPrivacyContract({success: (res) => {console.log('openPrivacyContract success')},fail: (res) => {console.error('openPrivacyContract fail', res)}})},/*** 拒绝隐私协议*/handleDisagree() {uni.setStorageSync('mpweixin_disagree_authorization', 1) if (this.disagreeEnabled) {this.$refs.privacyPopup.close()privacyResolves.forEach((resolve) => {resolve({event: 'disagree'})})privacyResolves.clear()this.$emit('disagree')} else {uni.showToast({icon: 'none',title: this.disagreePromptText})}},/*** 同意隐私协议*/handleAgree() {uni.setStorageSync('mpweixin_disagree_authorization', 0) this.$refs.privacyPopup.close()privacyResolves.forEach((resolve) => {resolve({event: 'agree',buttonId: 'agree-btn'})})privacyResolves.clear()this.$emit('agree')}}}
   </script>
   <style lang="scss" scoped>.ws-privacy-popup {width: 600rpx;padding: 48rpx;box-sizing: border-box;overflow: hidden;width: 560rpx;background: linear-gradient(180deg, #e5edff 0%, #ffffff 100%);border-radius: 24rpx;&__header {display: flex;align-items: center;justify-content: center;width: 100%;height: 52rpx;font-size: 36rpx;font-family: PingFangSC-Medium, PingFang SC;font-weight: 550;color: #1a1a1a;line-height: 52rpx;margin-bottom: 48rpx;}&__container {width: 100%;box-sizing: border-box;font-size: 28rpx;font-family: PingFangSC-Regular, PingFang SC;font-weight: 400;color: #333333;line-height: 48rpx;margin-bottom: 48rpx;&-protocol {font-weight: 550;color: #4D80F0;}}&__footer {display: flex;flex-direction: column;.is-disagree,.is-agree {width: 100%;height: 88rpx;background: #ffffff;border-radius: 44rpx;font-size: 32rpx;font-family: PingFangSC-Regular, PingFang SC;font-weight: 400;color: #666666;}.is-agree {background: #4D80F0;color: #ffffff;margin-bottom: 18rpx;}button {border: none;outline: none;&::after {border: none;}}}}
   </style>

7. util.js文件代码：
    

   /*** 获取当前页面上下文* @returns 页面对象*/
   export function getContext() {// eslint-disable-next-line no-undefconst pages = getCurrentPages()return pages[pages.length - 1]
   }/*** 获取上下文中指定节点组件* @param context 选择器的选择范围，可以传入自定义组件的 this 作为上下文* @param selector 自定义节点选择器*/
   export function getComponent(context, selector ) {let component = null// #ifdef H5context.$children.forEach((child) => {if (`#${child.$attrs.id}` === selector) {component = child} else if (child.$children && child.$children.length) {if (getComponent(child, selector)) {component = getComponent(child, selector)}}if (component) {return component}})// #endif// #ifdef MP-WEIXINcomponent = context.selectComponent && context.selectComponent(selector) && context.selectComponent(selector).$vm// #endif// #ifdef MP-ALIPAYconst alipay = context.$children ? context.$children : context.$vm && context.$vm.$children ? context.$vm.$children : []component = alipay.find((component) => {return `#${component.$scope.props.id}` === selector})// #endif// #ifdef APP-PLUSconst app = context.$children ? context.$children : context.$vm && context.$vm.$children ? context.$vm.$children :[]component = app.find((component) => {return `#${component.$attrs.id}` === selector})// #endifreturn component
   }

8. 一般到这里再次运行就可以成功了，成功的隐私弹窗:
   

9. 如果到这里了还没有成功！！！再来，检查一下弹窗控件对不对
   看一下components 文件夹下边有没有uni-popup文件夹，如果有，一定要删掉！！！
   否则会报错，​easycom组件冲突：[@/components/uni-popup/uni-popup.vue,@/uni_modules/uni-popup/components/uni-popup/uni-popup.vue]​
   如果有页面引用到了，引用的代码也删掉
   
   

10. Hbuilder x 工具更新到最新版本，导入最新版本uni-popup组件
    点击插件安装：
    

11. 找到 uni-popup插件，点击安装
    
    

12. 再次运行，就会弹隐私协议的窗口啦
