uniapp微信小程序，使用fastadmin完成一个一键获取微信手机号的功能

前端部分

点击按钮，获取手机号

<button open-type="getPhoneNumber" @getphonenumber="bindGetPhoneNumber" hover-class="none"class="btn-purity">一键获取</button>

传入openid和code

bindGetPhoneNumber(e) {var that = this;if (e.detail.errMsg == 'getPhoneNumber:fail user deny') {uni.showModal({title: '温馨提示',content: '您已拒绝授权，无法获取手机号！',showCancel: false,success: function(res) {if (res.confirm) {uni.$emit("getContract", {});uni.navigateBack();// uni.switchTab({// 	url: "/pages/home/index/index"// })}}});return;} else {var json = {openid: this.userInfo.openid,};let version = uni.getSystemInfoSync().SDKVersion;// json['encryptedData'] = e.detail.encryptedData;// json['iv'] = e.detail.iv;json['code'] = e.detail.code;this.$api.user.getPhone(json).then(res => {console.log(7777123, res)if (res !== false) {this.phoneNumber = res.data.mobile}});}},

后台部分

初始化EasyWechat的核心类

private $app;public $payment;public function __construct(){$config = get_addon_config('lineup');Log::write('[ Log LIST ++++++++++$config ] ' . json_encode($config, JSON_UNESCAPED_UNICODE), 'debug');$options = ['app_id'      => $config['app_id'],'secret'      =>  $config['app_secret'],'response_type' => 'array',];$payment_config = [// 必要配置'app_id'             => $config['app_id'] ?? '','mch_id'             => $config['mch_id'] ?? '','key'                => $config['mch_key'] ??

解析出手机号

public function decryptPhoneNumber($post){$wxmini = new \app\common\library\lineup\Wxmini();//新版本授权try {if(!empty($post['code'])){$return = $wxmini->getPhoneNumber($post['code']);}else if($post['iv'] && $post['encryptedData']){$return = $wxmini->decryptData($post['session_key'], $post['iv'], $post['encryptedData']);}else{throw new Exception("参数错误");}}catch (Exception | ErrorException $e){return ['status' => false,'info'   => $e->getMessage(),'data' => [],];}return ['status' => true,'data' => ['mobile' => isset($return['phoneNumber']) ? $return['phoneNumber'] : '',],];}
