抖音小程序一键获取手机号

前端代码组件
在这里插入图片描述

	<button v-if="!isFromOrderList"class="get-phone-btn" open-type="getPhoneNumber"@getphonenumber="onGetPhoneNumber">一键获取</button>

			// 获取手机号回调onGetPhoneNumber(e) {var that = this	tt.login({force: true,success(res) {console.log('获取手机号回调', e)if (e.detail.errMsg === 'getPhoneNumber:ok') {// 获取成功，调用后端接口解密手机号that.decryptPhoneNumber(res.code,e.detail.iv,e.detail.encryptedData)} else {uni.showToast({title: '获取手机号失败',icon: 'none'})}},fail(res) {console.log(`login 调用失败`);},});},// 解密手机号 后端PHP进行解密async decryptPhoneNumber(code,iv,encryptedData) {try {const res = await orderApi.decryptPhone({code: code,iv: iv,encryptedData: encryptedData})if (res.code === 1 && res.data && res.data.phone) {this.phone = res.data.phone} else {throw new Error(res.msg || '获取手机号失败')}} catch (error) {console.error('解密手机号失败:', error)uni.showToast({title: error.message || '获取手机号失败',icon: 'none'})}}

后端使用的PHP去实现思路首先通过前端的code换取sessionkey 然后通过 sessionkey解密前端手机号加密信息
