分享增加获取微信官方的获取手机号的功能，以及一些微信小程序的小Bug。

线上效果图：

操作如下：

在\fecshop_win\addons\fecmall\fecyo\lib\wxapp\文件夹放入微信官方的Demo，三个php文件

在fecshop\fecshop_wxapp\fecyo\pages\login\login.wxml文件的47行加上：

<button type="primary" class="save-btn" open-type="getPhoneNumber" bindgetphonenumber="getPhoneNumber" >{{language.read_form_weixin}}</button>

在fecshop\fecshop_wxapp\fecyo\pages\login\login.js文件

18行：去除默认手机号。

102行：只要将下面的代码替换掉从102行开始执行的函数即可。主要是增加保存session_key，顺带修复无伤大雅的小Bug，即：失败重复请求由7次改为作者备注的5次，

	success: function (res) {
        wx.hideLoading();
        app.saveReponseHeader(res);
        //console.log(res);
        if (res.data.code == '1100025') { // 没有相关用户，需要绑定
          that.setData({
            loadAccount: 2,
            userinfo:res.data.data,
          });
          //wx.setStorageSync('userinfo',userinfo);
    
          return
        }
        if (res.data.code == '200') { // 登陆成功，进行跳转
          wx.navigateBack({
            delta: 1
          });
          //that.globalData.uid = res.data.data.uid;
          //wx.navigateTo({
          //  url: "/pages/my/my"
          //})
        } else { // 其他的失败情况，重新进行登陆操作，最大5次
          // 如果获取微信数据失败，则重复获取，最大5次
          
          var reRequestCount = that.data.reRequestCount;
          that.setData({
            reRequestCount: reRequestCount + 1,
          });
          if (reRequestCount < 4) {//此逻辑是第五次执行后才跳过
            // wx.showModal({
            //   title: "提示",
            //   content: "微信登录失败，重试中",
            //   showCancel: false
            // });
            that.wxLogin();
          } else {
            wx.showModal({
              title: "提示",
              content: "微信登录失败",
              showCancel: false
            });
          }
          that.setData({
            loadAccount: 3,
          });
          return;
        }
      }

在文件末尾 }) 前面加上：

getPhoneNumber(e) {
var that = this,
session_key=that.data.userinfo.session_key,
encryptedData=e.detail.encryptedData,
iv=e.detail.iv,
openid=that.data.userinfo.openid;

if (e.detail.errMsg == 'getPhoneNumber:ok') {
  wx.checkSession({
    success:function(){
      that.deciyption(session_key,encryptedData,iv,openid);
    },
    fail:function(){
      that.wxLogin();
      that.deciyption(this.data.userinfo.session_key,encryptedData,iv,openid);  
    }
  })
}
},
deciyption(session_key,encryptedData,iv,openid){
var that = this;
wx.request({
  url: app.globalData.urls + "/customer/login/bindaccount2",  // "/user/wxapp/login",
  header: app.getPostRequestHeader(),
  method: 'POST',
  data: {
    session_key: session_key,
    encryptedData: encryptedData,
    iv: iv,
    openid: openid,
  },
  success: function (res) {
    wx.hideLoading();
    app.saveReponseHeader(res);
    //console.log(res);
    if (res.data.code == '1100026') {  // 无法通过微信api获取信息
      wx.showModal({
        title: "提示",
        content: "无法从Session中获取微信Openid，请重新绑定",
        showCancel: false
      });
      that.wxLogin();
      return;
    } else if (res.data.code == '1100027') { // 登陆成功，进行跳转
      wx.showModal({
        title: "提示",
        content: "您已经有绑定的账户",
        showCancel: false
      });
      return;
    } else if (res.data.code == '1100007') { // 没有相关用户，需要绑定
      wx.showModal({
        title: "提示",
        content: "注册账户失败: " + res.data.data.errors,
        showCancel: false
      });

    } else if (res.data.code == '1100029') { // 没有相关用户，需要绑定
      wx.showModal({
        title: "提示",
        content: "该邮箱已经存在，请点击`已有账户`，输入邮箱密码进行账户绑定",
        showCancel: false
      });

    } else if (res.data.code == '1100028') { // 没有相关用户，需要绑定
      wx.showModal({
        title: "提示",
        content: "用户的账户密码不正确，请重新输入",
        showCancel: false
      });
    } else if (res.data.code == '200') { // 没有相关用户，需要绑定
      //wx.navigateTo({
      //  url: "/pages/my/my"
      //})
      wx.navigateBack({
        delta: 1
      });
    } else {
      wx.showModal({
        title: "提示",
        content: "绑定失败，请重新绑定",
        showCancel: false
      });
      that.wxLogin();

    }

  }
});
},

在文件：\fecshop\fecshop_win\addons\fecmall\fecyo\app\appserver\modules\Customer\controllers\LoginController.php 在文件末尾 } 前加上下面代码：

    // 绑定账户
    public function actionBindaccount2()
    {   
        $encryptedData = Yii::$app->request->post('encryptedData');
        $iv = Yii::$app->request->post('iv');
        $wx_session_key = Yii::$app->request->post('session_key');
        $wx_openid = Yii::$app->request->post('openid');

        if (!$wx_openid || !$wx_session_key || !$encryptedData || !$iv) {
            $code = Yii::$service->helper->appserver->no_account_openid_and_session_key;
            $data = [ ];
            $responseData = Yii::$service->helper->appserver->getResponseData($code, $data);
            
            return $responseData;
        }
        
        if (Yii::$service->customer->getByWxOpenid($wx_openid)) {
            // 已经存在绑定的用户，绑定失败
            $code = Yii::$service->helper->appserver->account_has_account_openid;
            $data = [ ];
            $responseData = Yii::$service->helper->appserver->getResponseData($code, $data);
            
            return $responseData;
        }
        
        $resultData = $this->PhoneIpn($encryptedData,$iv,$wx_session_key);
        if (is_array($resultData)) {
             $phone = $resultData['phoneNumber'];
        } 

        if (!$phone) {
            $code = Yii::$service->helper->appserver->account_register_fail;
            $data = $resultData;//[ ];
            $responseData = Yii::$service->helper->appserver->getResponseData($code, $data);
            
            return $responseData;
        }    

        $param = [
            'phone' => $phone,
            'openid' => $wx_openid,
            'session_key' => $wx_session_key,
        ];
        $access_token = Yii::$service->customer->phoneRegisterAndGetLoginAccessToken($param);
        if (!$access_token) {
            $code = Yii::$service->helper->appserver->account_register_fail;
            $data = [
                'errors' => Yii::$service->helper->errors->get(),
            ];
            $responseData = Yii::$service->helper->appserver->getResponseData($code, $data);
            
            return $responseData;
        }
        $code = Yii::$service->helper->appserver->status_success;
        $data = [ ];
        $responseData = Yii::$service->helper->appserver->getResponseData($code, $data);
        
        return $responseData;
        
    }

    public function PhoneIpn($encryptedData,$iv,$sessionKey)
    {
        $wxBizDataCrypt = Yii::getAlias('@fecyo/lib/wxapp/wxBizDataCrypt.php');
        require_once($wxBizDataCrypt);
        
        $pc = new \WXBizDataCrypt(Yii::$app->store->get('payment_wxpay', 'wechat_micro_app_id' ),$sessionKey);
        $decryptData = "";  //解密后的明文
        $errCode = $pc->decryptData($encryptedData, $iv, $decryptData);
        if ($errCode == 0) {
            return json_decode($decryptData,true);
        } else {
            return $errCode;
        }       
    }

在61行左右，有个小瑕疵顺便说下：

        $phone = $wxCode = Yii::$app->request->post('phone');
        $captcha = $wxCode = Yii::$app->request->post('captcha');

改为：

        $phone = Yii::$app->request->post('phone');
        $captcha = Yii::$app->request->post('captcha');

框架作者如果要改，那就顺便把文件： fecshop\fecshop_win\vendor\fancyecommerce\fecshop\app\appserver\modules\Customer\controllers\LoginController.php

207行 到 209行的也改下：

        $isBindNew = $wxCode = Yii::$app->request->post('isBindNew');
        $email = $wxCode = Yii::$app->request->post('email');
        $password = $wxCode = Yii::$app->request->post('password');

同一文件的288行左右，将空数组改为含有session_key和openid信息的数组：

		// 如果$openid 没有 对应的customer，则需要先绑定或者创建相应的账户
        if (!$customer) {
            $code = Yii::$service->helper->appserver->account_wx_get_customer_by_openid_fail;
            $data = [];
            $responseData = Yii::$service->helper->appserver->getResponseData($code, $data);
            
            return $responseData;
        }

改为：

		// 如果$openid 没有 对应的customer，则需要先绑定或者创建相应的账户
        if (!$customer) {
            $code = Yii::$service->helper->appserver->account_wx_get_customer_by_openid_fail;
            $data = $wxUserInfo;
            $responseData = Yii::$service->helper->appserver->getResponseData($code, $data);
            
            return $responseData;
        }

在文件：fecshop\fecshop_win\addons\fecmall\fecyo\services\Customer.php

218行：

$session_key = $param['openid'];

Bug修复改为：

$session_key = $param['session_key'];

在文件：\fecshop\fecshop_win\vendor\fancyecommerce\fec\helpers\CApi.php

53行加入，这样本地开发才能获取openID。

            if (stripos ( $url, "https://api.weixin.qq.com" ) !== false) { 
            	curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);//绕过ssl验证
        		curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);
            }
