前端部分

点击按钮，获取手机号

<button class="button" open-type="getPhoneNumber" @getphonenumber="getPhoneNumber">一键获取</button>

传入sessionKey和encryptedData、iv

其中sessionKey是通过登录时，调用抖音接口https://developer.toutiao.com/api/apps/v2/jscode2session获得

encryptedData、iv则通过点击按钮回传的事件参数

  getPhoneNumber(e) {if (e.detail) {if (e.detail.errMsg == "getPhoneNumber:fail auth den") {uni.showToast({title: '小程序通过试运营期，才能一键获取手机号',icon: 'none'});}this.getUserPhone(e.detail)} else {this.hasPhoneValue = false}},async getUserPhone(query) {// douyin-ad-1ddba+123456 /admin/dyinAd/answerAdlet Authorization = this.$user.token || "none Authorization";let http_url = this.$config.base_url + '/app/user/login/getDyPhone'let http_data = {sessionKey: this.$user.sessionKey,encryptedData: query.encryptedData,iv: query.iv,"admin": this.$config.admin,}let http_header = {Authorization}let result = await this.$http.post(http_url, http_data, http_header, 'json').then(async (res) => {if (res && res.data) {let phone = {}Object.assign(phone, JSON.parse(res.data))this.formPhone = phone.phoneNumber}}).catch((err) => {});},

后端部分

解密手机号

async getDyPhone(query){const decipher = crypto.createDecipheriv("aes-128-cbc",Buffer.from(query.sessionKey, "base64"),Buffer.from(query.iv, "base64"));let ret = decipher.update(query.encryptedData, "base64", 'utf8');ret += decipher.final('utf8');return ret;}
